When a Miami school said earlier this week that it wouldn’t allow vaccinated teachers in its classrooms, its founder cited “vaccine shedding” as her main concern.
The trope is currently abuzz in anti-vaccine circles, said Nicole Baldwin, MD, a pediatrician who has been a target of attacks by the anti-vaxxer community.
“It’s amazing, and sad, what people will believe,” Baldwin told MedPage Today.
Essentially, they believe that people who’ve had the vaccine can somehow shed the spike protein, which in turn can cause menstrual cycle irregularities, miscarriages, and sterility in other women just by being in close proximity.
“This is a new low, from the delusional wing of the anti-vaxx cult,” said Zubin Damania, MD, a.k.a. ZDoggMD, in a video he recently posted to bust vaccine shedding myths.
Damania said the misinformation originates from an earlier claim that syncytin, a protein involved in placental formation, bears some structural similarities to the spike protein, and therefore vaccination would interfere with women’s reproductive systems. Many a fact check has shown that vaccines don’t target the protein.
Once injected, the vaccines prompt cells to make the spike protein, but it’s usually cleared in 24 to 48 hours, leaving little opportunity for “shedding,” even if it could occur — which it can’t, Damania emphasized.
Another logical fallacy he pointed out: “Why, then, wouldn’t natural spike protein do the same thing? Wouldn’t you be more scared of natural coronavirus infection? Oh, but it’s ‘natural.'”
Damania noted that there are legitimate questions and research about whether the coronavirus itself and vaccines have an impact on women’s menstrual cycles. Since the beginning of the pandemic, women who’ve had COVID-19 reported changes to their menstrual cycle, and Damania said that researchers are assessing reports of changes to the menstrual cycle following vaccination.
Regarding the potential relationship to vaccination, “we don’t understand, first, if it’s true, and if it were true, what is the mechanism?” he said. “Anything that causes stress, inflammation, and an immune response may have an effect on the menstrual cycle. … Could it be that the vaccine causes a temporary change in menses? Sure, it’s possible, and it’s being looked at.”
Leila Centner, co-founder and CEO of Centner Academy, the Miami school that has banned vaccinated employees, told NBC News in a statement that “tens of thousands of women all over the world” have reported reproductive issues from being around someone who has been vaccinated.
Baldwin pointed out an Instagram video, now marked as misinformation, in which a nurse, Maureen McDonnell, RN, and a physician, Lawrence Palevsky, MD, discuss the effect of vaccines on women’s menstrual cycles.
“This isn’t just a trivial thing,” Damania said. “It’s quite harmful.”
A new piece in the Atlantic sparked debate this week about the risk of ongoing COVID exposure to children as the country navigates toward the end of the pandemic. Brown University economist Emily Oster equated a child’s risk of serious illness from the coronavirus to that of their vaccinated grandmother. If grandma receives the Pfizer vaccine, her risk of serious illness is decreased by 95 percent. According to Oster, the condition of “being a child” aged 0-17 is 98 percent protective against hospitalization—so go ahead, plan that family summer vacation!
Oster cites no clinical or scientific experts in her piece, but some doctors were quick to respond that the comparisons are not equivalent (and also provide ready-made scripting for the “anti-vaxx” movement, which could claim that kids are already “basically vaccinated”).
But the article does bring up a real question that millions of families will soon face: what can we do when grandma and grandpa (and hopefully mom and dad) are vaccinated, but the kids are not? Given the pace of clinical trials, teens could be eligible for vaccination as soon as late summer, but COVID vaccines might not be approved for younger children until months later—and this generational vaccine divide will likely linger into 2022.
Undoubtedly children are at lower risk from COVID than adults, and likely transmit the disease less frequently (although much of the data supporting the latter comes from studies in schools, where social distancing and masking are enforced). And we’re not out of the woods yet: as COVID cases surge again in Michigan, schools there have seen a spike in outbreaks as well.
As families look at conflicting data and messages in the media, they need clear, coordinated guidance from state and federal officials to help them gauge safety as they navigate their second “pandemic summer”.
