The last two times I took a flu shot I got the flu badly within a week. One case within days. I stopped taking the flu shot (more than the decade ago) and I "may" have had the flu twice. Though maybe not even that in that time.
I am fairly certain my family and I had what is being called COVID in January of 2020. It felt like a nasty flu but did have some cyclic behavior that was new and I'd not experienced before. Plus family was tested for flu and pneumonia and both came back negative. This is before the CDC or WHO were saying anything about COVID. I was aware something was out there but it didn't yet have a name because I pay attention to more than just CDC and WHO.
At first I saw COVID as a potential huge threat.
Now I consider it far less of a threat than the flu.
The thing that is horrible and doing massive damage is the RESPONSE to COVID.
The things that have been done using it as an excuse are worse than any illness.
