My husband and I had our first vaccine shot today at a local hospital While we were standing in line we began conversation with another couple who had COVID in November, one hospitalized and one stayed home, their doctor said they should have the vaccine. So they went in for their shots and were there a short time and left without the vaccine. They were told that they could not get the vaccine until ninety days after having had COVID. THe staff at the hospital also told them that when they came back for the vaccine to take an OTC Benadryl before. So it sounds to me that the period of immunity must be 90 days.
Your conclusion is false. The reason she told them to wait 90 days was because the mRNA vaccine can react to the virus itself with Pathogenic Priming or Antibody Dependent Enhancement. It kills you.
