The big thing....If you're sick....STAY HOME !!
Since many people who are sick DON’T stay at home, I carry a container of disinfectant wipes in the car. Whenever I come back to the car from a store (grocery, hardware, etc.) I grab a wipe and clean my hands well. Maybe it’s my imagination, but it seems to help - don’t feel like I’ve caught as many ‘bugs’ since I’ve been doing this.
a meta-study analyzing 22-23 flu studies over the last 50 years to see the efficacy of the flu vaccine found that getting the flu shot only decreased your chances of getting the flu by 4%.
IOW it’s hardly effective and hardly worth it. especially if you already take hygiene/disinecting precautions with hands, exposure, etc.
I got a flu shot in November - lot of good it did me, been in bed three days with the flu!
