You need to see if you actually got the VIRUS about the same time. Your symptoms from the shot should have been mild, especially on the first shot. I don’t know of many who had much issue with the first. A few had symptoms for a day or two with the second shot.
Exactly. Start there. Possible that the old fashioned flu was contracted and independent of the Covid vax.
OTOH - vaccines are foriegn agents introduced to the human body to trigger an immune response, which is a very delicate and complicated cascade of events.
It is not without risk or complication. Whey we are talking about 100 million people, there is a % that will have adverse reactions.
You could have 5000 people have an adverse reaction, but out of 100 million, that is 0.00005%. If you are one of that minute percentage, it suxs, but that
does not mean the treatment is bogus. I repeat, it is not without risk.
