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?
- Immunity declines over time.
- Flu viruses constantly evolve, so a new vaccine is administered every year.
Can I still get sick with the flu even after vaccination?
- It is possible to be exposed to a flu virus shortly before getting vaccinate, so the vaccine will not have time to build antibodies to protect you.
- Different flu viruses go around every year (3 or 4 vaccines per year), so it is possible to be exposed to a flu virus not included in the seasonal flu vaccine(s).
- Overall health and 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 vaccinated annually (end of October) to allow time for antibodies to be generated.
- Can be administered as shot or nasal spray
