If anybody told you vaccines are safe they are lying to you
The ‘flu vaccines seem to be generally safe. Whether they’re effective or not is another question.
I’ve taken it twice. Once, I got the ‘flu anyway.
The other time, I felt like hell - and as if I were coming DOWN with the ‘flu - for several months.
I don’t take that anymore. But I might take a Covid vaccine, if my doc thought it was thoroughly tested.
