The vaccine, it is like wearing underwear.This is not because you did it last year that you should not the
Similarly, as with underwear, the protection afforded by a flu vaccine does not last forever.The duration of protection can vary considerably from person to person, but in some cases, the protection may disappear after about 6 months, which is still much longer than wearing underwear.This is one of the reasons why you should get vaccinated Every year, baduming you have at least 6 months, because you can read this and you do not have any medical (for example, a life-threatening allergy) to not receive the vaccine.
Another reason is that strains of the flu virus are like stars in reality TV. Different come and go from one year to the next. Therefore, strains of an influenza vaccine, and therefore the strains against which you are protected, vary from one year to the next.
And if you are concerned that the annual influenza vaccine will reduce your immunity to the flu, look at the study that was published in JAMA . In fact, do not just look at it, read it. For the study, a research team recruited children who had visited outpatients at Baylor Scott & White Health (Temple, Texas), Marshfield Clinical Research Institute (Marshfield, Wisconsin), Vanderbilt University Medical Center (Nashville, Tennessee) and Wake. School of Forest Medicine (Winston-Salem, North Carolina) during the 2013-2014, 2014-2015 and 2015-2016 influenza seasons. To be able to participate in the study, a child had to have fever and acute respiratory illness and be real children (ages from 2 to 17 years old) instead of true immature adults. The research team finally recruited 3369 children in the study. Every child has received an influenza test. The researchers checked whether each child had received the flu shot the previous year. This allowed the researchers to divide the children into 4 groups, depending on whether or not they received the influenza vaccine the year of enrollment and the year before:
- Received the vaccine both in the year of registration and the year before.
- Received the vaccine just the year of enrollment
- Received the vaccine only the year before.
- did not receive the vaccine the previous year
About 23% (or 772) of the children were tested positive for the flu. About half (1674) had received the influenza vaccine. Each year, the children could have received one of two different types of influenza vaccine: one that contained the live but weakened virus that squirted the nose and one that contained the dead virus injected into the arm.

Researchers have attempted to evaluate the effectiveness of the influenza vaccine by comparing the percentage of people who tested positive influenza screening among those who received the vaccine. compared to those who did not receive the vaccine during the year of enrollment. Of course, this is a somewhat indirect way to estimate the effectiveness of the flu shot. In addition, children visiting a clinic for fever and respiratory diseases do not necessarily represent the general population.
Nevertheless, the study did not reveal any evidence that being vaccinated the previous year reduced its effectiveness. In other words, according to the results of the study, receiving the vaccine last year will not reduce the effectiveness of the vaccine and increase the risk of getting the flu this year. In fact, the results of the study suggest that having the vaccine the year before could help further strengthen the protection of the vaccine against certain types of influenza, type B.
So, why not get vaccinated all years, as the Centers for Disease Control and Prevention (CDC) recommends? And change your underwear a lot, a lot more often. If you want to maximize your immunity against the flu, you must get vaccinated every year. There is no scientifically proven way to dramatically increase your immunity against this virus that could kill you, regardless of your condition. Of course, staying healthy by eating well and doing physical activity can help to some extent. But a supplement, a particular food or a magic potion will not offer you the same immunity as a flu shot. Do not listen to supplement vendors who claim to have protection against the flu and who have no scientific evidence to support it. Like underwear that lasts too long, many false claims about protection against the flu can become really lousy.

the protection afforded by a flu vaccine does not last forever.If the duration of protection can vary significantly from one person to the other, in some cases it may after about 6 months, which is much longer than you should wear it, which is one of the reasons why you should get the flu shot every year, baduming you have at least 6 months, because you can read it and you have no medical reason (eg an allergy danger of death) to not receive the vaccine.
