My pediatrician recommends that I get flu vaccination done for my daughter every year and she suggests that even adults should get it. Is it really helpful?
Influenza A viruses which causes flu keep mutating and evolving each year in course of shifting between animal and human hosts and thus can easily escape the already immunized person’s immune response and can make them sick. Flu shots are designed every year by properly matching vaccine antigens with the circulating viruses. So, it is recommended to get flu shots every year till the age of 9 years. People having weak immunity like senior citizens, pregnant women (after first trimester) and persons with certain medical conditions (lung or heart disorders; metabolic disorders e.g. Diabetes, kidney ailments, etc.; and immunosuppression) should also get the current Influenza vaccine.
