Contagious respiratory illness caused by influenza viruses infecting nose, throat, and sometimes lungs
– Sore throat
– Runny/stuffy nose
– Muscle/body ache
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
