Every single assisted living facility that has had COVID outbreaks was COVID-free before the outbreak. Then, someone who was infected and likely had no symptoms entered, and COVID-19 began to spread.
This has been happening way before anyone got a flu shot. This conspiracy theory nonsense about the flu shot causing COVID is going to get a lot of people killed.
My contention is that flu shot MAY cause immune system problems. Especially for weaker folks.
And, more people will be killed because medical community does not check vit d3 levels, IMHO.
