NBC News (KNBC-TV) interviewed Dr. Kristen Choi, UCLA Fielding School of Public Health assistant professor of health policy and management, about research by the National Institutes of Health that suggests mixing vaccines may enhance the immune response to the COVID-19 virus.
A government study of 450 people says that "mixing vaccines may enhance the immune response" to the COVID-19 virus.
In light of that research by the National Institutes of Health, some public health experts tell the I-Team people might want to switch vaccines when getting booster shots.
"For people who got the J&J vaccine originally, their protection was much greater if they get an MRNA vaccine as their second booster," said Professor Kristen Choi of UCLA's Fielding School of Public Health and School of Nursing.
