Flu Vaccination

Influenza (flu) is a contagious respiratory illness caused by influenza viruses. The influenza virus changes every year and develops new strains. Therefore, it is necessary to vaccinate each year.

Even when vaccinated against influenza, it is important to keep projection measures, as the vaccination does not provide guaranteed full immunity.  Therefore, keep all measures like hygiene, social distance and wearing mask.  

A vaccination against influenza can significantly reduce the risk for you to contract the virus and develop an influenza illness. If you may fall ill with influenza, the vaccination can reduce the risk of more serious complications.  

As the influenza virus constantly mutates, there is no guaranteed natural or vaccinated immunity from previous shots. Therefore, an updated vaccination at the beginning of flu season is required. The exact time frame of the seasonal influenza can vary. Therefore, it is recommended to get the vaccination when it becomes available for 2021 (expected at second half of October). 

The vaccine itself cannot cause influenza, as the shot does not include live viruses. Instead, it contains inactivated particles. These particles are not alive and cannot cause respiratory illness. 

For the vaccine to become effective, it usually takes about 2 weeks.  

As with all vaccines and medications, also influenza vaccines may cause side effects, like feeling feverish, redness or swelling at the injection spot, etc. These side effects usually resolve within a few days and do not require treatment and your body starts producing antibodies for immunity.  

Allergic reactions are uncommon, however always consult with your physician.
