The mechanism for menstrual irregularities after COVID vaccination? Not really.

Robert F. Kennedy, Jr.’s running mate Nicole Shanahan posted a link to a bad study “explaining” menstrual issues caused by COVID vaccines. It’s an in vitro study that explains almost nothing. It’s basically the scientific equivalent of clickbait.

COVID-19 vaccines and female infertility: A lie that never dies

Antivaxxers have long claimed that vaccines can cause female infertility. That claim has been resurrected for COVID-19 vaccines. This time, it’s the lipid nanoparticles attacking the ovaries, echoing very old claims about polysorbate-80. Truly, everything old is new again.

Shedding: An antivax trope resurrected for COVID-19 vaccines

Antivax pediatrician Dr. Larry Palevsky recently demonized COVID-19 vaccines by resurrecting the old antivaccine trope of vaccinated people “shedding” and causing illness in the unvaccinated.

Consistent with that delusion, her latest study of HPV vaccination is all amateurs hour, in which she misses a major potential confounder on her way to “proving” that HPV vaccination could be associated with decreased fertility in young women.
