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.
Absolutely no question the flu vaccine works. It can be debated whether everyone should get it, but the gigantic pandemics do not occur like they used to occur.
Disinfectant wipes help as well.
