Harvard Medical School and the Boston University School of Public Health are among a group of institutions awarded funding to study potential links between coronavirus vaccinations and changes in menstruation.

Researchers at five institutions were awarded a total of $1.67 million by the National Institutes of Heath to look into the question after anecdotal reports from women earlier this year that after they were vaccinated, they saw changes, including earlier, heavier, and more painful periods.
