5 Reasons To Get A Flu Shot Every Year
The Body Makes Antibodies for Protection

Unfortunately, the research isn't always correct about what strain of the flu will be prevalent in a particular season. Sometimes a new strain can develop, or another one appears out of nowhere. This is often why strains like H1N1 can be devastating. However, even in cases where this happens, it is still important to receive the flu shot every year. Even when the prevalent strains do not match the vaccine, the body will still create antibodies, which can help it fight other strains of the flu. And as stated numerous times, the vaccines make it easier to fight the flu and lessen the severity of the flu when someone does catch it. This applies even when strains do not match!
