Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said there may not be enough time to study the efficacy of receiving one vaccine dose and people should stick to the available data.
Some experts have supported the idea of delaying second doses of Covid-19 vaccines in order to get as many people as possible vaccinated with at least a first dose.
Speaking to NBC’s Chuck Todd Sunday, Fauci said: “From a theoretical standpoint, it would be nice to know if you just get one dose, how long the durability lasts and what is the level of effect... But, what we have right now and what we must go with is the scientific data that we’ve accumulated and it’s really very solid.”
The current data say people should get a booster dose 21 days after their first Pfizer shot and 28 days after the first Moderna shot.
“You can do both. You can get as many people in their first dose, at the same time as adhering within reason to the timetable of the second dose,” Fauci said. “So it would be great to have the study, but I don’t think we could do it in time.”
