My brother in law got vaccinated in December(With Pfizer) he recently had a blood test done to show if he has any antibodies and it said yes..not sure how much it was just a yes or no blood test. My Mom had her vaccine in March, she got a different antibody blood test done and it showed her antibody number at 960 not sure if that is good or not..the doc said he’s seen people with 20,000
1) Did either veer away from the 3 week gap between doses and wait longer for their 2nd dose? Studies show delaying the 2nd dose as Canada/UK have done creates more immune durability.
2) Did either have Covid? I would imagine those who’ve had Covid have higher counts...
