Can a vaccinated person ‘shed’ the COVID-19 vaccine, causing unvaccinated people in close proximity to have changes in their period or miscarriages?

It is biologically impossible for a vaccinated person to “spread” the vaccine to someone else. Also, evidence shows that the COVID-19 vaccines do not cause miscarriages in those who have gotten it.

False posts online inaccurately blamed “extended or extremely heavy cycles” on “being around people who are recently vaccinated and shedding.” Some falsely claimed miscarriages were “up 400%.”

Dr. Jen Gunter, an obstetrician-gynecologist in the Bay Area, told AP that the vaccine cannot be shed: “It is not biologically possible for the vaccine to do that.”

COVID-19 vaccines also do not affect fertility or cause miscarriages, data shows.

“Not only do they not cause miscarriages in the people who are near vaccinated people, they do not even cause miscarriages in the people who got them during pregnancy,” Dr. Andrea L. Cox of Johns Hopkins University School of Medicine told AP.
