The one and two-dose vaccines produced no measurable level of antibodies in nearly all of the hundreds of thousands of organ recipients in the US. A third dose

The one and two-dose vaccines produced no measurable level of antibodies in nearly all of the hundreds of thousands of organ recipients in the US. A third dose produced some measurable response in about 40% of people as per a Johns Hopkins study. My Dad luckily had some response from a third shot. I got the Pfizer two shot and a booster and I wear a mask daily when indoors to prevent the spread and creation of new variants to protect others.
