It can start out mild, then turn severe

You can be contagious even before you feel symptoms including fever, cough, sore throat, body aches and fatigue. People age 65 and older with certain conditions are at higher risk of severe flu which can lead to hospitalization.

It’s updated yearly

The virus changes, so flu shots are updated to help protect against the types scientists think will be most common.

It’s also recommended after age 65 if you have heart disease, asthma, COPD, diabetes, or other conditions that put you at higher risk of severe flu. Even if you feel healthy, the immune system weakens with age, making it harder to fight respiratory infections including flu.

When temps dip to 41°F or colder, flu starts to spread.

That’s why vaccination is recommended in September and October, before the temperature drops.
