Multidose COVID-19 vaccines will test state tracking systems: People have to get two shots of the same type of vaccine (12/04/2020) | @verge
… Both take two doses, given a few weeks apart, and both could be circulating at the same time. And that’s just the two front-runners. Other multidose vaccines are still in the development pipeline.
There are a few ways states, doctors, and patients could keep the dosages straight, says Claire Hannan, executive director of the Association of Immunization Managers. In the simplest solution, everyone who gets a COVID-19 vaccine will also get a card that tells them which vaccine they had and when their next dose should be. But that’s the last line of defense in a complex vaccine tracking system. “As the backup to the backup to the backup, they’ll hand out cards,” Hannan says.
Ideally, the cards won’t be necessary because patients and doctors will be able to rely on electronic records and digital registry systems to keep track of who got which vaccine and when they got it. Through the pandemic, states have struggled with digital systems for other key areas, like COVID-19 testing – sometimes relying on fax machines and incomplete, handwritten forms to send information from testing sites to local health departments. But Hannan says the US immunization data collection systems at the state level are prepared to manage the expected crush of information from an unprecedented mass vaccination campaign like the one the country is about to start. Most tools were in place even before the pandemic hit. …
Big health systems with robust electronic health record management will likely have an easier time with this process than smaller clinics, says Howard Forman, a professor of public health, management, and economics at Yale University. “They’re used to keeping track of whether patients have had their followup appointments…
… Each state has its own Immunization Information System (IIS), a centralized registry that keeps track of every vaccine each person vaccinated in that state has received. Vaccination clinic software and electronic health records systems feed into those registries, which help doctors keep track of the vaccination records for individual patients, and also give each state big-picture data on vaccination rates in individual communities.
A state-level IIS can also notify doctors and patients when people are due for a second dose of a vaccine. They already use them to keep track of doses for the meningitis B vaccine…
The systems in place to track vaccinations today are much more advanced than they were in 2009, when the country struggled to distribute and track the H1N1 flu vaccine (which was only one shot), and electronic health records were rare. Only some states used their IIS programs. Many states had to rely on SurveyMonkey to connect with health care providers about vaccine delivery…

Moderna reaffirms 20M vaccine dose goal for December (12/04/2020) | @BosBizJournal
… The biotech has enlisted Italian firm Lonza to ramp up production to 500 million to one billion doses of the vaccine annually and Catalent Inc. to make all of the labels, seals and glass vials. Local life sciences unicorn Ginkgo Bioworks has also been helping Moderna optimize its production of raw materials for the drug.
Moderna has additionally hired another 150 employees to produce the vaccine out of its Norwood manufacturing facility. …

Moderna to submit Covid-19 vaccine to FDA as full results show 94% efficacy (11/30/2020) | @statnews
… Moderna said that safety data is being reviewed continuously, but that there are no new serious safety concerns. The most common adverse events included site pain, fatigue, muscle or bone pain, headaches, and redness at the injection site. The reactions were more serious in the vaccine group after patients received a second dose. The results Pfizer and BioNTech released 12 days ago for their vaccine are roughly similar. …
… Each strand of synthetic mRNA is designed to encode for a protein found on the surface of SARS-CoV-2, the virus that causes Covid-19. Those mRNA strands enter the body’s cells and instruct them to produce that protein. The immune system then recognizes it as a foreign invader and produces antibodies that protect against Covid-19 if a person is later exposed to the virus.
The Covid-19 vaccine would be Moderna’s first product approved by the FDA and, assuming Pfizer’s vaccine is approved first, only the second mRNA medicine ever licensed. …

Moderna’s COVID-19 Vaccine Candidate Gets More Good News (w Voice; 11/30/2020) | @NPR
… Both use the same novel technology. Instead of injecting a weakened or dead virus, which is a common strategy for vaccines, these products are essentially small pieces of genetic material. When that’s injected into a person’s arm, it’s picked up by cells in the immune system. The cells read the genetic code and use that to produce a protein that is actually a key fragment of the coronavirus. The body then builds antibodies that latch onto that fragment, so if and when someone encounters the actual coronavirus, the body is primed to fight it off with antibodies. …

Pfizer And Moderna Face Their Biggest Challenge: Vaccinating The World (12/03/2020) | @IBDinvestors
… The obstacles can’t be overestimated, experts say. The vaccine supply chain is mindbogglingly complex. It involves local, state and federal authorities as well as hospitals, pharmacies and doctors’ offices.
The two most advanced coronavirus vaccines must be stored at specific temperatures and given in two doses several weeks apart. Stakeholders must keep tabs on who gets which vaccine and when. And don’t forget the public perception challenges of vaccinating people with drugs that went through clinical testing at record speeds.
Experts say 60% to 80% of the world must be vaccinated to achieve herd immunity. It will be many months – or years – before that happens as vaccine makers iron out supply constraints. Besides the Covid-19 vaccine companies themselves, a raft of other parties like drug distribution company McKesson (MCK) will be involved.
…the Centers for Disease Control and Prevention. The agency has overseen vaccine distribution in the U.S. for decades, including the national effort to vaccinate during the H1N1 influenza pandemic in 2009.
The coronavirus vaccination effort will probably look similar to that…
First, vaccination sites will need to enroll in the CDC’s Covid-19 vaccine distribution program. These sites will include doctors’ offices, clinics, hospitals and pharmacies. The program ensures these locations have enough well-trained staff, the right equipment and space to vaccinate large numbers of people.
Then, the vaccination sites will request doses of the coronavirus vaccine through a state agency…
Public health officials will then confirm the vaccination site is approved. If so, the order will head to the CDC. …
In August, the CDC tapped McKesson to help it distribute all coronavirus vaccines. …McKesson could rely on UPS, DHL and FedEx trucks to help it get the job done.
Pfizer, on the other hand, has a bigger challenge. The company’s coronavirus vaccine must be stored at ultracold temperatures. How cold? Penguins would find these temperatures chilly. …
Moderna’s vaccine can live in a standard refrigerator for 30 days. It can also be frozen for six months. Once thawed, providers must administer the vaccine within 12 hours – or toss it out. That creates a logistical challenge for transportation.
“Moderna will be heavily reliant on external suppliers…It will be using companies like CryoPort (CYRX), Stirling Ultracold and CH Robinson (CHRW) to work out cold chain logistics plus storage and shipping management.” …
…Pfizer has developed a special shipping container that can store the coronavirus vaccine for 10 days unopened…
The vaccine can be stored in an ultracold freezer for up to six months. It can stay in the shipping container for up to 30 days when replenished with dry ice every five days. Or, the drug can be stored for five days in a standard refrigerator.
…the strict storage requirements limit where Pfizer’s vaccine can be used. Those ultracold freezers cost about $20,000 apiece. …
…”Imagine getting one dose to Appalachia, a rural community. Now imagine having to come back and making sure everyone who got the first dose also gets the second one. That’s a challenge.”
…it’s likely the Pfizer vaccine will go to more populous locations with cold-storage capabilities. Coronavirus vaccine stock Moderna will probably send its drug to more rural communities.
…expects Pfizer to generate $875 million in coronavirus vaccine sales in 2020 and $7.25 billion in 2021. Eventually, that will trend down to $700 million to $800 million each year, depending on how often people need booster shots of the vaccine. …
“The drugmaker that gets this thing out first…Overnight, Pfizer becomes one of the most loved brands in America. It’s the McDonald’s (MCD) of the pharma industry.”

Pfizer to Ship Half as Many Coronavirus Vaccine Doses as Originally Planned in Initial Phase (12/03/2020) | @themotleyfool
…”Scaling up the raw material supply chain took longer than expected, and it’s important to highlight that the outcome of the clinical trial was somewhat later than the initial projection.”
BNT162b2, which showed an extremely high efficacy rate of 95% with no serious safety concerns in phase 3 clinical trials, has been submitted for similar approvals throughout the European Union, and with the U.S. Food and Drug Administration (FDA). In the wake of the U.K. approval, Pfizer and BioNTech anticipate decisions from other major regulators this month. …

Pfizer and BioNTech announced in July an agreement with the U.K. to supply 30 million doses of its mRNA-based vaccine…increased to 40 million doses in early October. As a two-dose vaccine, the U.K. will have enough doses to vaccinate around a third of its 66 million population. …
“I consider this decision to be problematic and recommend that EU Member States do not repeat the process in the same way. A few weeks of thorough examination by the European Medicines Agency is better than a hasty emergency marketing authorization of a vaccine,” said Peter Liese, a member of German Chancellor Angela Merkel’s party…

…multilayered masks with water-resistant fabric, high number of threads, and finer weave may be more protective… Masks should be able to prevent a stream of fluid flowing at a pressure of up to 160 mm Hg from seeping through the mask and potentially into the mouth. …
Cloth masks…ideally washing in hot water with soap. Other methods or products include using bleach, isopropyl alcohol, or hydrogen peroxide; autoclaving or microwaving; and application of ultraviolet radiation or dry heat…
…in a widespread pandemic, differentiating asymptomatic from healthy persons in the community is very difficult, so at least in high-transmission areas, universal face mask use may be beneficial. The general public should be educated about mask use because cloth masks may give users a false sense of protection because of their limited protection against acquiring infection…

Late Sequelae of COVID-19 (11/13/2020) | @CDCgov
Characterization of the etiology and pathophysiology of late sequelae is underway, and may reflect organ damage from the acute infection phase, manifestations of a persistent hyperinflammatory state, ongoing viral activity associated with a host viral reservoir, or an inadequate antibody response. Factors in addition to acute disease that may further complicate the picture include physical deconditioning at baseline or after a long disease course, pre-COVID-19 comorbidities, and psychological sequelae following a long or difficult disease course as well as those relating to lifestyle changes due to the pandemic. Likely, the persistent sequelae of COVID-19 represent multiple syndromes resulting from distinct pathophysiological processes along the spectrum of disease.
Though there is limited information on late sequelae of COVID-19, reports of persistent symptoms in persons who recovered from acute COVID-19 illness have emerged. The most commonly reported symptoms include fatigue, dyspnea, cough, arthralgia, and chest pain. Other reported symptoms include cognitive impairment, depression, myalgia, headache, fever, and palpitations. More serious complications appear to be less common but have been reported. These complications include:
・Cardiovascular: myocardial inflammation, ventricular dysfunction
・Respiratory: pulmonary function abnormalities
・Renal: acute kidney injury
・Dermatologic: rash, alopecia
・Neurological: olfactory and gustatory dysfunction, sleep dysregulation, altered cognition, memory impairment
・Psychiatric: depression, anxiety, changes in mood

Long-term Health Consequences of COVID-19 (w PDF; 10/05/2020) | @JAMA_current
Manifestations
The most commonly reported symptoms after acute COVID-19 are fatigue and dyspnea. Other common symptoms include joint pain and chest pain. In addition to these general symptoms, specific organ dysfunction has been reported, involving primarily the heart, lungs, and brain. From a pathogenesis standpoint, these complications could be the consequence of direct tissue invasion by the virus (possibly mediated by the presence of angiotensin-converting enzyme 2 receptor), profound inflammation and cytokine storm, related immune system damage, the hypercoagulable state described in association with severe COVID-19, or a combination of these factors.
Cardiovascular
Myocardial injury, as defined by an increased troponin level, has been described in patients with severe acute COVID-19, along with thromboembolic disease. Myocardial inflammation and myocarditis, as well as cardiac arrhythmias, have been described after SARS-CoV-2 infection. … However, an increased incidence of heart failure as a major sequela of COVID-19 is of concern, with considerable potential implications for the general population of older adults with multimorbidity, as well as for younger previously healthy patients, including athletes.
Pulmonary
…interstitial thickening and evidence of fibrosis. …decreased diffusion capacity for carbon monoxide and diminished respiratory muscle strength…
Neurologic
…headache, vertigo, and chemosensory dysfunction (eg, anosmia and ageusia). …encephalitis, seizures, and other conditions such as major mood swings and “brain fog”…

…brain fog, fatigue, difficulty concentrating…
Who will experience coronavirus sequelae?
…“Sequelae of the disease have been seen in people with mild cases of COVID-19.”
In other words, it’s not yet proven who is affected by sequelae.
What are the symptoms of coronavirus sequelae?
Fever; Fatigue; Muscle or body aches; Joint pain; Shortness of breath; Difficulty concentrating (or “brain fog”); Nausea, heartburn, or vomiting; Headache; Difficulty sleeping; Prolonged loss of taste or smell; Hair loss …
… “There are some individuals who may have long-lasting kidney damage, blood clots, or other problems of the blood vessels and skin as well as worsening hypertension (high blood pressure).”
…lasting effects on the heart. …cardiac involvement…myocardial inflammation…lasting damage to the lungs, including post-COVID fibrosis.
What causes coronavirus sequelae?
…the SARS-COV-2 utilizes the spiky protein on its membrane to interact and bind to the ACE 2 receptors, which can be seen in the lungs, heart, and various organs to trigger an inflammatory response…
…inflammation of the heart muscle…heart palpitations, fast heart rate (tachycardia), irregular heartbeat or chest pressure…
… Part of the cascade of events includes the release of cytokines, in the blood, which mediate subsequent immune responses against the foreign invader (the virus). In the event where such mediators cross the blood brain barrier and accumulate in the central nervous system, they can activate the primitive regulatory parts of the brain phenomenon, resulting in many of the symptoms seen in post-viral syndrome. This was also observed in select patients who contracted SARS during the 2002-2003 outbreak.”
What should you do if you experience coronavirus sequelae?
Taking over-the-counter pain relievers such as Tylenol or ibuprofen; Eating a balanced and healthy diet; Getting plenty of sleep and resting during the day as needed; Practicing relaxation techniques such as yoga, massage therapy, and meditation

Coronavirus (COVID-19) Update: FDA Authorizes Drug Combination for Treatment of COVID-19 (11/19/2020) | FDA
…an emergency use authorization (EUA) for the drug baricitinib, in combination with remdesivir, for the treatment of suspected or laboratory confirmed COVID-19 in hospitalized adults and pediatric patients two years of age or older requiring supplemental oxygen, invasive mechanical ventilation, or extracorporeal membrane oxygenation (ECMO).
… Baricitinib is not authorized or approved as a stand-alone treatment for COVID-19. …
Baricitinib is a janus kinase inhibitor, which blocks the activity of one or more of a specific family of enzymes, interfering with the pathway that leads to inflammation. Baricitinib is a prescription oral tablet medication that is FDA-approved (and sold under the brand name Olumiant) for the treatment of moderately to severely active rheumatoid arthritis. …
Remdesivir is an FDA-approved (and sold under the brand name Veklury) intravenous antiviral drug for use in adult and pediatric patients 12 years of age and older and weighing at least 40 kilograms (about 88 pounds) for the treatment of COVID-19 requiring hospitalization. Remdesivir also remains authorized for emergency use for the treatment of suspected or laboratory-confirmed COVID-19 in hospitalized pediatric patients weighing 3.5 kg (about 7.7 pounds) to less than 40 kg or hospitalized pediatric patients less than 12 years of age weighing at least 3.5 kg. …
… Possible side effects of baricitinib in combination with remdesivir include serious infections, blood clots, changes in certain lab test results and allergic reactions.
The EUA was issued to Eli Lilly and Company. …

… Remdesivir is also being studied in combination with other medications. Early results reported that hospitalized COVID-19 patients who got both remdesivir and baricitinib (Olumiant) recovered about 1 day faster than those who only got remdesivir. Additionally, patients had a 30% higher chance of clinical improvement at day 15 when taking both medications together. The full data has not been shared yet.
Not all remdesivir studies have been promising. On October 15, 2020, a large, randomized study from the World Health Organization (WHO) found that remdesivir had little or no effect on death rate in hospitalized patients with COVID-19. The death rate was about 11% regardless of whether patients got remdesivir or not. These results have not been peer-reviewed yet. …

Experimental drug given to Trump to treat covid-19 wins FDA clearance: But Regeneron’s antibody treatment is expected to be in short supply. (11/21/2020) | @washingtonpost
… The drug, made by Regeneron Pharmaceuticals, is designed to prevent infected people from developing severe illness. Instead of waiting for the body to develop its own protective immune response, the drug imitates the body’s natural defenses. It is the second drug of this type — called a monoclonal antibody — to be cleared for treating covid-19. The FDA authorized Eli Lilly & Co.’s drug on Nov. 9.
Regeneron’s drug is a cocktail of two monoclonal antibodies, called casirivimab and imdevimab. The FDA said in authorizing the cocktail that it may be effective in treating mild to moderate covid-19 in adults and children 12 or older, and is indicated for those at high risk of developing severe illness. Doctors hope the drugs will keep those patients from being hospitalized.
But as with the Lilly treatment, the Regeneron drug is a biological product that is complicated and time-consuming to make…
In a study published Oct. 28 in the New England Journal of Medicine, researchers said the Lilly cocktail lowered the risk of follow-up medical visits and reduced levels of virus in people with mild to moderate symptoms of covid-19. …
Through Operation Warp Speed, the Trump administration effort to speed up treatments and vaccines, the government has bought 300,000 doses each from Lilly and Regeneron at a cost of about $1,250 and $1,500 per dose, respectively, with an option to buy hundreds of thousands more. But that comes as the nation is approaching 200,000 new coronavirus cases each day.
In a sign of how quickly the supply could be used up as the pandemic surges across the country, 40 percent of the doses of Lilly’s bamlanivimab has already been allocated to states. …

Rheumatoid arthritis drug appears to help Covid patients in ICU: Trial suggests that tocilizumab improves outcomes for critically ill patients, say researchers (19/11/2020) | @guardian

Efficacy and safety of tocilizumab in COVID-19 patients: A living systematic review and meta-analysis (w PDF; 11/05/2020) | @CMIJournal
Conclusion
Cumulative moderate certainty evidence shows that tocilizumab reduces the risk of mechanical ventilation in hospitalized COVID-19 patients. While RCTs showed that tocilizumab did not reduce short-term mortality, low certainty evidence from cohort studies suggests an association between tocilizumab and lower mortality. We did not observe a higher risk of infections or adverse events with tocilizumab use. This review will continuously evaluate the role of tocilizumab in COVID-19 treatment.

Efficacy of Tocilizumab on Patients With COVID-19 (08/24/2020) | @MGHMedicine,@genentech ClinicalTrials.gov @nlm_news
Brief Summary:
This is a randomized, double blind, multi-center study to evaluate the effects of tocilizumab compared to placebo on patient outcomes in participants with confirmed SARS-CoV-2 infection and evidence of systemic inflammation.
The aim of this study is to test the effect of Tocilizumab on multi-organ dysfunction in a phase 3 randomized controlled trial among hospitalized patients with COVID-19 infection.
Specifically, as compared to placebo, we will test whether tocilizumab is associated with a reduction in multi-organ dysfunction among hospitalized COVID-19 adult patients with elevated inflammatory measures. Multi-organ dysfunction will be measured as the incidence of the following composite endpoint (mechanical ventilation, renal replacement therapy, mechanical support, need for inotropes or vasopressors, liver dysfunction (increased bilirubin), and all-cause mortality). We will also assess multiple pre-specified secondary (exploratory) endpoints and safety endpoints.
We hypothesize that, as compared to placebo, tocilizumab will reduce transfer to the ICU, need for mechanical ventilation, increase rates of hospital discharge in patients diagnosed with severe COVID-19 infection and evidence of exaggerated inflammatory response.

The FDA has authorized convalescent plasma treatment for coronavirus patients – but some scientists worry it’s too soon (08/26/2020) | @businessinsider
During the 1918 Spanish flu pandemic, doctors discovered they could treat sick patients with the blood of those who had already recovered. …
Antibodies develop in plasma, the liquid portion of blood – they’re part of our body’s natural response to a foreign pathogen. So the idea behind the treatment is to help sick people mount an antibody response to the virus by transferring plasma intravenously from those who already have antibodies.
“What we really need are drugs that, when given early, can prevent a symptomatic person from requiring hospitalization or very dramatically diminish the time that they’re symptomatic,” …
… Plasma must be transferred quickly from a donor to a recipient – and both must have compatible blood types. The quantity is also limited, since it depends on blood donations. …
A national study of 35,000 hospitalized coronavirus patients, which is still awaiting peer review, found that patients less than 80 years old who weren’t on a respirator and received plasma containing high levels of antibodies within three days of their diagnosis had a 35% lower mortality rate than those who were treated four or more days after their diagnosis.
The process of creating hyperimmune globulin involves pooling plasma from recovered patients and heat-treating it so that any remaining pathogens get destroyed. The result is a vial of medicine with consistent antibody levels that can easily be administered to patients. The drug focuses on the most common antibody found in blood ? immunoglobulin G (IgG) – which usually confers long-term immunity.

Key Facts About Seasonal Flu Vaccine | @CDCgov
FluVaccines_CDC1-table1FluVaccines_CDC2-recommended&viruses
Flu Vaccination
How do flu vaccines work?
Flu vaccines cause antibodies to develop in the body about two weeks after vaccination. These antibodies provide protection against infection with the viruses that are used to make the vaccine.
The seasonal flu vaccine protects against the influenza viruses that research indicates will be most common during the upcoming season. Most flu vaccines in the United States protect against four different flu viruses (“quadrivalent”); an influenza A (H1N1) virus, an influenza A (H3N2) virus, and two influenza B viruses. There are also some flu vaccines that protect against three different flu viruses (“trivalent”); an influenza A (H1N1) virus, an influenza A (H3N2) virus, and one influenza B virus. Two of the trivalent vaccines are designed specifically for people 65 and older to create a stronger immune response.
What kinds of flu vaccines are available?
CDC recommends use of any licensed, age-appropriate influenza vaccine during the 2020-2021 influenza season, including inactivated influenza vaccine [IIV], recombinant influenza vaccine [RIV], or live attenuated influenza vaccine (LAIV). No preference is expressed for any influenza vaccine over another. Both trivalent (three-ingredient) and quadrivalent (four-ingredient) influenza vaccines will be available.
Quadrivalent flu vaccines include:
Standard-dose quadrivalent influenza shots that are manufactured using virus grown in eggs. These include Afluria Quadrivalent, Fluarix Quadrivalent, FluLaval Quadrivalent, and Fluzone Quadrivalent. Different influenza shots are licensed for different age groups. These four vaccines are approved for people 6 months of age and older. Most influenza shots are given in an arm muscle with a needle. One quadrivalent influenza shot (Afluria Quadrivalent) can be given either with a needle (for people aged 6 months and older) or with a jet injector (for people aged 18 through 64 years only). …
Are any of the available flu vaccines recommended over others?
…the Advisory Committee on Immunization Practices (ACIP) recommends…including inactivated influenza vaccine (IIV), recombinant influenza vaccine (RIV), or live attenuated nasal spray influenza vaccine (LAIV4)…
Who Should Not Be Vaccinated?
… Factors that can determine a person’s suitability for vaccination, or vaccination with a particular vaccine, include a person’s age, health (current and past) and any allergies to flu vaccine or its components. …

Vaccine Benefits
What are the benefits of flu vaccination?
Vaccine Match
What if circulating viruses and the vaccine viruses are different?
Why is there sometimes not a good match between a vaccine virus and circulating viruses?
Flu viruses are constantly changing (called “antigenic drift”) ? they can change from one season to the next or they can even change within the course of one flu season. Experts must pick which viruses to include in the vaccine many months in advance in order for vaccine to be produced and delivered on time. …
… While all influenza viruses undergo changes when they are grown in eggs, changes in influenza A(H3N2) viruses are more likely to result in antigenic changes compared with changes in other influenza viruses. These so-called “egg-adapted changes” are present in most of the vaccine viruses recommended for use in egg-based vaccine production and may reduce their potential effectiveness against circulating influenza viruses. …

Flu Vaccine (Flu Shot) | @MedicineNet
Facts you should know about the influenza vaccine (flu shot)
・Types of influenza (flu) vaccines include the injection (killed virus), recombinant (made without flu virus), and nasal spray vaccines (containing live virus). …
What is influenza (flu)?
… Flu is a respiratory infection, that is, an infection that develops primarily in the lungs. People often call respiratory infections caused by other viruses the flu, but this is incorrect. These other infections are usually categorized as URIs (upper respiratory infections) and have multiple causes. …
Influenza viruses are divided scientifically into three types, designated A, B, and C. Influenza types A and B are responsible for epidemics of respiratory illness that occur almost every winter. Influenza type C usually causes either a very mild respiratory illness or no symptoms at all; it does not cause epidemics and does not have the severe public health impact of influenza types A and B. Type A viruses are divided into subtypes and are named based on differences in two viral surface proteins called hemagglutinin (H) and neuraminidase (N). There are 16 known H subtypes and nine known N subtypes. …
The so-called swine flu pandemic of 2009 was caused by a novel influenza A virus designated H1N1 based upon its surface protein types. This virus was originally referred to as swine flu because many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs in North America. However, this virus was actually quite different from the typical swine flu viruses found in pigs.

Types of seasonal influenza vaccine | @WHO_Europe
Two types of influenza vaccine are widely available: inactivated influenza vaccines (IIV) and live attenuated influenza vaccines (LAIV). Traditionally, influenza vaccines (both IIV and LAIV) have been produced to protect against 3 different seasonal influenza viruses (also called trivalent vaccines). In most countries this is still the case and the current trivalent vaccines contain influenza A(H3N2), pandemic A(H1N1) and 1 of 2 influenza B lineage viruses. However, recently vaccines which protect against 4 different viruses, including both influenza B lineage viruses (quadrivalent vaccines), have become available in some countries. …
Annual selection of viruses
The composition of influenza vaccines (both IIV and LAIV) are updated annually by WHO based on information gathered from the Global Influenza Surveillance and Response System (GISRS)…

Flu vaccine | @NHSuk
Flu vaccine and coronavirus (COVID-19)
Flu vaccination is important because:
・if you’re at higher risk from coronavirus, you’re also more at risk of problems from flu
・if you get flu and coronavirus at the same time, research shows you’re more likely to be seriously ill
・it’ll help to reduce pressure on the NHS and social care staff who may be dealing with coronavirus
If you’ve had COVID-19, it’s safe to have the flu vaccine. It’ll be effective at helping to prevent flu.
