Mixing and matching coronavirus vaccines for booster shots is safe and effective, says a new study by the National Institutes of Health.

The study’s preliminary data shows recipients of the one-dose Johnson & Johnson vaccine whose booster shot was either of the two-dose Moderna or Pfizer versions had the biggest immune response, according to U.S. News & World Report.

The study, which hasn’t been peer-reviewed, found that people who originally got the Moderna or Pfizer vaccines and then got either one as a booster dose had similar immune responses, U.S. News reported.

So far, booster shots have generally been restricted to those 65 and older and people with underlying medical conditions or high-risk jobs or living situations.

As of Thursday, only about 5% of the U.S. population has gotten a booster dose, according to the Centers for Disease Control and Prevention.
