A flu shot is a vaccine for several strains or influenza virus. This year, you get the shot and “the flu.” What happened? (There are at least three explanations.)
To explain: The reason why a person who got the flu shot for several strains of influenza virus yet got the flu infection.
Concept introduction: The flu shots or flu jabs are the vaccines that protect against the infection by the influenza virus. As the influenza virus rapidly changes, a new version of this vaccine is developed twice a year. The vaccination against influenza can reduce sickness, medical visits, hospitalizations, and also deaths.
There are chances that the influenza virus is infected to the person may not be included in that year’s vaccine. There is another possibility that the body does not develop the antibodies properly against the viruses...
