The flu is an infection caused by the influenza virus, which affects the nose, throat and sometimes the lungs.
According to the World Health Organization, the vaccine is one of the ways to prevent it.
There are many myths surrounding this vaccine that are confusing to many patients, however. For example: that it can be harmful to pregnant women, that the virus will become stronger as it spreads, or that it is no longer effective after the flu season. Despite the existence of these myths, according to the Centers for Disease Control and Prevention (CDC), these myths have not been proven.
How does it work?
“Flu vaccines cause antibodies to develop in the body about two weeks after vaccination. These antibodies provide protection against infection with the viruses that are in the vaccine,” states the CDC’s webpage.
Flu vaccines are approved to be administered to pregnant women and to patients with chronic health conditions. Children under age six and people that are allergic to the vaccine’s ingredients should not receive it. It is always best, however, to consult with your doctor prior to getting it.
