NIH trial finds mixing and matching boosters is safe and effective
A study from the National Institutes of Health published in the New England Journal of Medicine found mixing and matching boosters are safe and create a similar immune response to sticking with your initial vaccine.
An earlier version of this study, with more preliminary findings, helped guide the CDC's decision to allow mix-and-match.
The study authors make no claims about specific combinations being more or less effective. The study did find that people who got an mRNA vaccine (Pfizer or Moderna) and then received the Johnson & Johnson booster had a significant increase in T-cell response, a part of immunity.
The trial looked at 458 participants who received a vaccine with no prior COVID-19 infection. This data is only for the first 29 days after receiving the booster; researchers plan to follow the participants for one year, allowing for more data.
