One day after an FDA advisory panel signed off on the Pfizer coronavirus vaccine and with emergency use authorization expected sometime in the next 24 hours, experts at the Johns Hopkins Bloomberg School of Public Health shared a virtual update on what they’ve learned so far, and what challenges we face moving forward.
One of the most interesting moments in the virtual update came after one of the panelists, Dr. Brian Garibaldi, was asked a pretty personal question.
“As soon as the vaccine is available, I plan to get vaccinated,” Garibaldi said. “We have a system in place. We don’t anticipate having enough vaccine for all of our frontline health care providers up front, so there will be a process that I’ll go through at Hopkins and when my number comes up, I plan to get vaccinated.”
And what about the rest of Maryland? Bill Moss, executive director of the Johns Hopkins International Vaccine Access Center, sharpened the timeline for the general public.
“Eventually, there will be sufficient doses of vaccine in the United States for everyone who should and wants to get it, but that’s not going to be until mid to third quarter of 2021,” Moss said.
It’ll be sometime between June and September, Moss said, assuming there are no hiccups with the manufacturing process, he said.
How long after getting a shot would he expect someone to have immunity?
Moss answered, in terms of the Pfizer candidate: “That 95% efficacy that we talk about? That’s starting seven days after the second dose. However, their trial did show that there was protection starting after the first dose, maybe 10 to 14, or 12 to 14 days after the first dose, maybe 82% protection after first dose. So, there is some partial protection actually, substantial protection after the first dose.”
