Covid-19: Fourth dose of mRNA vaccines is safe and boosts immunity, study finds, BMJ

Year of publication

Fourth doses of covid-19 mRNA vaccines are safe and provide a substantial boost to antibody concentrations and cellular immunity when given more than six months after a third dose of Pfizer’s vaccine, a study has found.


The latest findings from the UK Cov-Boost study, published in Lancet Infectious Diseases, compared antibody and T cell responses after a fourth dose of an mRNA covid-19 vaccine with immune responses after a third dose. Giving a fourth dose of Pfizer’s and a half dose of Moderna’s vaccine was effective at increasing antibody levels and cellular immunity up to and above the baseline and peak levels seen after third dose boosters, the results show.
