A fascinating paper in the Journal of the American Medical Association hints the answer may be yes
Last week, JAMA published a paper comparing natural-plus-vaccine Covid immunity versus vaccine-only immunity in over 500,000 people in Qatar.
Researchers looked at about 140,000 people who had received either the Pfizer or Moderna vaccines after a previous Covid infection and 400,000 who received the vaccines and had no prior infection.
No surprise, they found combined immunity is far superior to vaccine-only immunity.
After adjusting for age and other factors, people who had received vaccines but didn’t have natural immunity were about SIX times as likely to be infected with Covid as those who had a base of natural immunity.
