General | Latest Info

The 2020 - 2021 flu season is not shaping up to be a normal one. That's not to say it is going to be particularly bad: Clues from the Southern Hemisphere, where flu season is well underway, actually hint that it will be a mild year for Influenza across the globe. But it will be exceedingly complicate. First of all, mild flu season in the Southern Hemisphere is probably due in large part to masks and social distancing. Second of all, coronavirus is still raging in the US and if flu season packs hospital,ss mortal dangers of both COVID - 19 and flu increase. Coming down with a cough and fever could also mean locking down in quarantine while you wait for COVID - 19 test results. It is more crucial than ever to get your flu shot. This year, getting vaccinated for the flu will be a bit different too. For one, kids can get vaccinations and flu shots at pharmacies, new approval by the Trump administration. Many pharmacies can give adults flu shots too. And it is more important than ever to get vaccinated on time. August is too soon because protection might wear off by heavy - hitting months later in season. But September is ideal and you should definitely be up to date by the end of October, though later is better than never. There are also new and improved flu vaccine options for older adults, who are hit hard by both the flu and COVID - 19. And the government may require some people to get flu shots, such as Massachusetts, which is mandating vaccines for students. Every year, scientists around the world do their best to get one step ahead of the flu by developing that years iteration of flu shot. As a reminder, vaccines work by giving your body the chance to fight off altered versions of viruses or bacteria, so that if and when it encounters a live virus, it already knows how to react, and you never get sick. But what is in flu shot is a little more complicated. The recipe starts with four most popular Influenza strains from around the world, injected into fertilized chicken eggs or mammalian cells, deactivated so it doesnt give you actual flu, mixed with a grab - bag of preservatives, antibiotics, and sugars, and then formulated for shot or spray to make it in time for 2020 flu season. For those science - is - fucking - awesome types out there, this is indeed fucking awesome. It is also complex as hell, something that keeps virologists on their toes every year. Influenza strains constantly mutate, but scientists get one shot at annual vaccine, making their best guess some 30 weeks in advance to get flu shot out to the public. Fortunately, CDC published its recommendations for 2020 - 2021 flu shot on Friday, meaning it is actually possible to understand what you have injected into yourself and your child, wherever it is you get your flu shot.

Polysorbate 80

Immunization is a global health and development success story, saving millions of lives every year. Vaccines reduce risks of getting disease by working with your body's natural defences to build protection. When you get a vaccine, your immune system responds. We now have vaccines to prevent more than 20 life - threatening diseases, helping people of all ages live longer, healthier lives. Immunization currently prevents 2 - 3 million deaths every year from diseases like diphtheria, tetanus, pertussis, influenza and measles. Immunization is a key component of primary health care and an indisputable human right. It is also one of the best health investments money can buy. Vaccines are also critical to prevention and control of infectious - disease outbreaks. They underpin global health security and will be vital tool in the battle against antimicrobial resistance. Yet despite tremendous progress, far too many people around the world - including nearly 20 million infants each year - have insufficient access to vaccines. In some countries, progress has stalled or even reverse, and there is a real risk that complacency will undermine past achievements. Global vaccination coverage - the proportion of world children WHO receive recommended vaccines - has remained the same over the past few years.

Formaldehyde

Image also claim that formaldehyde is in flu vaccines and that it is a carcinogen and also causes infertility and hormone imbalance. Formaldehyde is used in production of some vaccines, including some flu vaccines, to kill bacteria or viruses. Vaccine protects you against. Because of that, traces of it may get into the final vaccine. The Vaccine Knowledge Project at University of Oxford says that the amount of natural formaldehyde in two month - old blood is around ten times greater than the amount found in any vaccine. Or, to give another comparison, that pear contains around 50 times more formaldehyde than any vaccine. Formaldehyde is carcinogenic and can cause skin and eye damage, but only in certain concentrations. The amount that could potentially get into Vaccine is a lot lower than this. Studies on formaldehyde and fertility have looked at these hazards among people who work with chemicals at concentrations far higher than youd ever find in Vaccine.

Preamble

The most common way that flu vaccines are made is using an egg - base manufacturing process that has been used for more than 70 years. Egg - base Vaccine manufacturing is used to make both inactivated Vaccine and live attenuate Vaccine. The egg - base production process begins with CDC or another laboratory partner in WHO Global Influenza Surveillance and Response System providing private sector manufacturers with candidate Vaccine viruses grow in eggs per current FDA regulatory requirements. These CVVs are then injected into fertilized hen eggs and incubated for several days to allow viruses to replicate. Fluid containing viruses is harvested from eggs. For inactivated Influenza Vaccines, vaccine viruses are then inactivate, and virus antigen is purify. The Manufacturing process continues with quality testing, filling and distribution. For nasal spray Flu Vaccine, starting CVVs are live, but weaken viruses that go through different production process. Fda tests and approves all Influenza Vaccines prior to release and shipment. There are several different manufacturers that use this production technology to make flu vaccines for use in the United States. This production method requires large numbers of chicken eggs to produce the vaccine and may take longer than other production methods.

Availability and characteristics of specific products and presentations might change and / or differ from what is described in this table and in the text of the full report. History of severe allergic reaction to egg is labeled contraindication to use of most IIVs and LAIV4. However, ACIP recommends that persons with a history of egg allergy may receive any licensed, recommended influenza vaccine that is otherwise appropriate for their age and health status. Those who report having had reactions to egg involving symptoms other than urticaria or who require epinephrine or another emergency medical intervention should be vaccinated in inpatient or outpatient medical settings supervised by a health care provider who is able to recognize and manage severe allergic reactions, If vaccine other than ccIIV4 or RIV4 is use. The Dose volume for Afluria Quadrivalent is 0. 25 mL for children aged 6 through 35 months and 0. 5 mL for people aged 3 years. Im - administer influenza vaccines should be given by needle and syringe only, with the exception of MDV presentation of Afluria Quadrivalent, which may alternatively be given by PharmaJet Stratis jet injector for persons aged 18 through 64 years only. For adults and older children, recommended site for intramuscular influenza vaccination is deltoid muscle. The preferred site for infants and young children is the aspect of thigh.

Efficacy

According to the CDC, flu vaccines reduce the odds of getting the flu by about 60%. But that number varies from year to year and among different groups of people. You may wonder why there's such a wide range. And in fact, it's even wider than it seem: that statistic only applies to healthy adults. It turns out that the effectiveness of Flu Vaccine depends on a number of different factors. Here's rundown of what they are. Flu Vaccine doesn't work equally well for all people. Itas most effective in healthy adults. In young children under 24 months, Flu Vaccine is a little less effective at preventing Flu. Itas more effective as children get older. After middle age, immunity naturally becomes weaker. Flu Vaccine wonat work as well as it once did. But because the flu virus is much more dangerous for older people, it is crucial that they get the vaccine. Even in cases where it does prevent the flu, it can still reduce the risk of serious side effects. Studies show that in older people who do not live in care facility, Flu Vaccine can cut the risk of hospitalization by 30% to 70%. In people who do live in nursing homes or care facility, flu vaccine is 50% to 60% effective in preventing hospitalization and 80% effective in preventing death from flu complication.S There may also be slight differences depending on which vaccine you get. This season, American Academy of PediatriciansA recommends that pediatricians offer Flu shotA to all children aged 6 months and older. Shot has provided the most consistent protection against Flu virus in recent years. Along With CDC, AAP supports use of nasal spray vaccine for children ages 2 and older for the 2018 - 19 Season, but the spray'sa effectiveness against / H1N1 strain of virusA is unknown. A high - dose vaccine called Fluzone is recommended for adults aged 65 and older when available. High - Dose Flu shots contain four times as much active ingredient as regular flu shots tp provide better immunity.

Vaccination Timing

Recently, concerns have arisen regarding the need for annual Influenza vaccinations and optimal timing of Influenza Vaccination and Vaccine effectiveness. Protective immunity generated by vaccine typically takes up to 2 weeks to develop, with moderate effectiveness lasting about 6 months. Annual Vaccines are designed to introduce the immune system to any mutations a virus has make. Repeated vaccinations were found to be effective in preventing severe and fatal influenza, especially in older adults, highlighting the importance of annual Influenza Vaccination. 25 with arrival of flu shots as early as July, question is, how early is too early? It has been recommended to receive Influenza Vaccine before Influenza Season begin, typically by the end of October. However, many people are beginning to receive them as early as August due to widespread availability. It is estimated that Influenza Vaccine loses between 6% and 11% of its absolute effectiveness per month, depending on Influenza strain. 26 Fears that patients may be receiving vaccines too early have led to studies evaluating use of compressed Vaccine schedule by limiting distribution of vaccines until the beginning of October. Using 2014 - 2015 Influenza Season strain distributions, delaying vaccination to October or later results in a decrease of 11 423 cases, with projections of 481 fewer hospitalizations and 134 fewer deaths for people aged 65 years and older in the US. However, this statement assumes that the total number of vaccinations received by patients will remain the same despite new restrictions on distribution and that Influenza peak will occur in February. Although the effects of this limited schedule on the total number of patients getting vaccinated are uncertain, decrease of at least 3. 5% in 20142015 Influenza Season would reverse benefits and result in more Influenza cases. 27. Secondly, if there were early Influenza peak, then late vaccine schedule would result in more cases as well. Similar results were shown when Flu Vaccines were given early in season during the late Influenza peak. 28 Recommending the optimal time for Influenza Vaccination is difficult; Influenza seasons are unpredictable, and limiting distribution may result in fewer people receiving vaccine. However, CDC does recognize that getting vaccinated too early, such as in July or August, may be associated with reduced protection later in the Influenza season, especially in older adults. Cdc recommends that individuals receive their vaccinations early in fall, before Flu Season begin, but no later than the end of October. Vaccinations beyond this date may still be beneficial, and vaccines should be offered throughout the entire Influenza Season.

Adverse Effects

There are many misunderstandings about the influenza vaccine and its side effects. The common misconception about the influenza vaccine is that it can cause influenza. Both IIV and LAIV are safe and cannot cause the flu. The most common side effect of IIV is soreness or redness at the site of injection. Systemic effects, including fever, malaise, and myalgias, may occur in a small percentage of individuals, most often in those who have had no previous exposure to influenza virus antigens in the vaccine. These Adverse reactions are usually mild and self - limiting, most resolving in 2 days or less. In clinical trials, HD - IIV injection site and systemic reactions were more frequent. Similarly, an is associated with more pain and tenderness at the injection site within the first 7 days. Studies have shown small association between the influenza vaccine and Guillain - Barre syndrome; although rare, those with a history of this disorder should be cautious when weighing benefits versus risks. 30 - 33 every ingredient found in a vaccine has a purpose, whether it is providing immunity, preserving product, or necessary component of production. One ingredient found in multidose vials is preservative thimerosal, which is metabolized to ethyl mercury. Following Administration, ethyl mercury is found in much lower concentrations in the brain and has a much shorter elimination half - life compared with its commonly mistaken counterpart, methyl mercury. Small amounts used to preserve vaccine do not cause mercury - associated adverse events, such as tremors. Formaldehyde is used to inactivate viruses and is diluted during later stages of the manufacturing process, but trace amounts may still be found in vaccine. Concentration found in vaccines is much smaller than the amount that appears naturally in the body and, thus, is not a concern. Egg protein is used to allow viruses to grow and replicate before it is harvest. Acip provides recommendations for people who are allergic to egg products.


Are flu vaccines safe?

Children younger than 6 months cannot get flu shot. Those who 've had severe allergic reaction to flu vaccine in the past should generally not be vaccinate, CDC say. You should not get the flu vaccine if you have high fever. However, if you have minor illness, like a mild cold or headache, you can still get flu shot, Schaffner say. Vaccines do perfectly well in those folks. But people who have COVID - 19 should not get flu shot until they have met criteria to discontinue isolation, according to the CDC. Although people can generally get flu shots if they have mild illness, they should not go get flu shots while they could be contagious with COVID - 19 to avoid exposing health care workers and other patients to the virus, CDC say.

What kinds of flu shots are there?

Exactly when flu season starts and ends is unpredictable, so health officials recommend that people get their flu shot in early fall, preferably by the end of October, CDC say. The same recommendation applies this year during the COVID - 19 pandemic. Flu activity typically peaks in January or February. We d like to get as many people protected against influenza before influenza becomes active in communities across the country, Schaffner say. Most flu vaccines are given before Thanksgiving, Schaffner say, but people can still get their shot throughout winter months. Each season's flu shot expires in June of that year, but Schaffner said that he would consider it too late to get flu vaccine after March, unless person is traveling to the Southern Hemisphere. After vaccination, it takes person about two weeks to build up immunity against flu. People can visit CDC's vaccinefinder. Org to find flu shot locations.
