How flu vaccination works in Russia, Germany, the U.K., and eight other countries

Flu vaccination occurs in late October, as recommended by the World Health Organization. It takes about two weeks for the vaccine to provide protection. Protection gradually decreases, so the timing affects immunity at season's end. The European Center for Disease Prevention and Control advises having immunity by mid-November.

High-risk individuals include those with chronic conditions, older adults (65+), pregnant people, children under five, those on aspirin-like medications, and individuals with a BMI of 40 or higher. Healthy adults rarely become seriously ill, so the benefit per vaccinated person is low, but preventing illness in the vulnerable benefits everyone.

Vaccination procedures vary by country, typically requiring a doctor's visit or being available at pharmacies or mobile clinics. Some countries provide free vaccination for high-risk groups and frequent contactees. In Russia, Armenia, and Germany, details can be found on regional health websites.

Vaccines like Ultrix Quadri, Flu-M, and Flu-M Tetra contain 15 micrograms of hemagglutinin per dose, which is equivalent to foreign vaccines. Other vaccines, such as Grippol Plus and Sovigripp, contain less of the active ingredient but are still considered effective. The nonprofit Kollektivny Immunitet recommends using whatever vaccine is available.

It's never too late to get vaccinated if the flu is still circulating, even in the spring. Other preventive measures include handwashing, avoiding touching faces, maintaining distance from sick people, staying away from crowded places, disinfecting frequently touched objects, and wearing FFP2 respirators for high-risk individuals.
