Dr. Anthony Fauci said this week that we will soon learn what the data show about mixing-and-matching COVID-19 vaccines.

Fauci, the director of the National Institute of Allergy and Infectious Diseases, said at a White House press briefing that there will soon be data about whether you can use the Johnson & Johnson vaccine as a booster for Pfizer and Moderna shots.

  • “Then the data looking at Pfizer as the (booster) to the (others) will be available somewhere in the first week or at the most, (second week) of October,” Fauci said, per the New York Post.
  • Fauci also said there is data available on whether you can use the Moderna vaccine as a booster for other vaccines, but he didn’t share the results of that data, according to New York Post.

Fauci’s comments come as the Food and Drug Administration authorized the booster shot of the Pfizer-BioNTech COVID-19 vaccine for those who received the first two doses of the Pfizer vaccine. Questions still surround whether or not people who got the Moderna or Johnson & Johnson vaccines can get a booster.

Fauci said on  NBC News’ “Meet the Press” last Sunday that the data on that idea is coming soon.

  • “The actual data that we’ll get (on) that third shot for the Moderna and second shot for the J&J is literally a couple to a few weeks away,” he said. “We’re working on that right now to get the data to the FDA, so they can examine it and make a determination about the boosters for those people.”
