Bay Area man believes he has immunity to COVID-19 after participating in Pfizer's vaccine trial

A Bay Area man volunteered for Pfizer's COVID-19 vaccine trial and now believes he could be part of the data that indicates Pfizer's vaccine may be 90% effective.

"When I left I didn't feel any different. My arm was a little bit sore."

That was in September, after Lafayette resident, Daniel Horowitz, received his first injection during Pfizer's coronavirus vaccine trial.

 

"I met the criteria because I'm over 65, but I'm in good health," he said.

Horowitz also says it helped that he has some potential exposure to the virus as an attorney who meets with clients and goes to court.

The trial is double-blinded, so neither Horowitz or the researchers know whether he received the vaccine or the placebo.

Three weeks later, after his second injection at a medical facility in Walnut Creek, Horowitz said, "I got little achy in my muscles, I just don't feel right... "It went away after that day and I said, 'I think I got a real side effect.'"

So Horowitz decided to get an antibody test to check for immunity, outside of the trial, which came back positive.

"You have a lot of antibodies and she was thrilled, so I started crying and I just said, 'then we're out of this, it's going to be over, it's going to be okay.'"
