re: Covid vaccine check in

My NP wife has taken 2 of the Pfizer vaccinations,1’st she had no side effects,2’nd she had low grade fever,chills and body aches about 24 hours.
I haven’t taken it yet but I will when it’s convenient,I’m not worried about it enough to make appointment and all that.
Based on studies I’ve read and our experience in our family I really believe Vit D3 is huge when it comes to prevention.My wife has been around a hundred plus patients plus bunch co-workers that got the Covid and she never got it.Our immediate family(15 people) have all been on Vit D3 and none of us have gotten it.
We’re all good about wearing masks in stores ,etc.She ,of course,wears one all day at work.Here at the house,we all still get together for meals and visits just like we always did pre-Covid.It’s possible we’ve just been lucky.
