That’s a very broad statement on your part!
A lady I know, in her 50’s, got it and she said she had the worse migraine type headache plus other symptoms
It took a good friend of mine, in her 60’s, 5 weeks to recover.
I would say both women were healthy when they contracted it.
Anecdotal I know.....but your statement was nebulous.
Have your anecdotes (which I have no reason to believe they are not true) caused you such concern that you have or plan to receive the vaccine? Just curious, that’s all.
