CHICOPEE, Mass. (WWLP) – As more information becomes available and eligibility for the booster shots increase, is mixing vaccines a safe way to stop the spread of COVID-19?

As the country’s top public health organizations continue to debate the booster shots, the National Institutes of Health report says mixing and matching of COVID-19 boosters is safe and effective.

The National Institutes of Health says that all three of the Moderna, Pfizer and Johnson and Johnson boosters created an increase in antibody levels regardless of which initial vaccine was received.

Patients who originally got Johnson and Johnson saw stronger immune responses when they received a Moderna or Pfizer booster.
