First of all, you should stick to the calendar and at the age of 16 update vaccinations against diphtheria and tetanus. If a person in childhood did not receive the full range of these vaccinations, he is vaccinated according to a separate scheme, since it is very important to receive all doses and form a full protection.
It is also extremely important to get vaccinated against polio, especially to people who travel frequently.
These vaccinations must be repeated every 10 years. The assertion that there are age restrictions and that older people are not vaccinated is erroneous.
Older people also need immunization
Why flu shots should be done every season
You need to be vaccinated against influenza every year, because the viral strains are different every season. The flu virus is very mobile and it is constantly changing. There are separate institutions that study the hepatitis virus.
At the beginning of the year, somewhere in February-March, they begin to predict which strains of viruses will be relevant in the next epidemiological season.
Also, experts monitor the migration of migratory birds that carry it: there are varieties of viruses that are characteristic only for them.
It happens that the strain repeats in the next season, it happens that it is very different. The virus is characterized by so-called antigenic drift and shift. Drift is a seasonal change in the virus, not very noticeable. Shift is its qualitative change that occurs due to the accumulation of quantitative ones. Antigenic shift usually gives a high rise in incidence.
And therefore, it is so important to be vaccinated against the flu every year – this trains the immune memory.
However, it should be understood that the vaccine does not insure against influenza – it prevents complications and severe forms of the disease.
It is especially important to be vaccinated for people who are at risk: doctors, employees of closed institutions, law enforcement agencies, and teachers. It is also important for people with chronic diseases, cancer patients.
They additionally need to re-vaccinate against pneumococcus.
The most vulnerable to influenza are older people, especially if they are limited in mobility or bedridden. The vaccine protects against complications, and it is because of them that older people most often die if they get the flu.
This virus is capillarotoxic, it provokes real vascular catastrophes. The consequences of the flu can be heart attacks and strokes.
In fact, getting vaccinated against flu is important for everyone. And at 30, and at 50, and at 90, vaccinations can and should be done. Life is changing, people communicate, travel, go to the cottage and come into contact with the earth. Infections threaten them at any age.
