Mix and Match Booster Vaccine Recommendations: What You Should Know

“Mix and match COVID-19 vaccine,” also known as heterologous booster vaccination, means everyone who’s eligible for a booster can either stay with their original brand or opt for a new COVID-19 vaccine if they prefer. A recent study found that people who received the Johnson & Johnson vaccine produced stronger antibody levels after they got booster shots made by Moderna or Pfizer compared to boosters from Johnson & Johnson. The study researchers also found that those who were originally vaccinated with the Pfizer or Moderna vaccines and received either company’s booster shot produced similarly strong immune responses.
