Q & A

Why is a flu shot needed every year?
(1) Immunity declines over time
(2) Flu viruses constantly change/evolve so a new vaccine is administered EVERY year

Can I still get sick with flu even after vaccination?
It is possible to be exposed to flu virus shortly before getting vaccinated so vaccine will not have time to build antibodies to protect you

Different flu viruses go around every year (3 or 4 vaccines made per year) so it is possible to be exposed to a flu virus not included in the seasonal flu vaccine(s)

– Overall health/age factors can affect susceptibility (older people and people with chronic illnesses may have weaker immune systems)

The Flu Vaccination

– Everyone 6 months and older should get it ANNUALLY (end of October) to allow time for antibodies to be generated

– Can be administered as shot or nasal spray
