My husband took the Pfizer........( &health wise he is my major concern)
.....he had absolutely no problems
....he Is taking a healthy dose of Vitamin D daily
I had the Moderna......no reactions other than.a bit of tiredness the next day
I’m also taking a daily Vitamin D supplement every day
When we took the vaccine we also took Ibuprofen before and after the jab......and every 4 hours through the day
As do I. I also take Zinc daily as the combination of Vitamin D and Zinc is supposed to be the most effective.
I read that here on FR, researched it to confirm it and found the posts here to be accurate. Hope this is helpful to you.
