In recent weeks, opponents of the Covid vaccination have spread a statement not only false, but defying the biological rules: that being around the person who received the vaccine can disrupt the cycle. women’s menstrual periods or cause miscarriage.
The idea, promoted on social media by accounts with hundreds of thousands of followers, are vaccinated people who could spill vaccine material, affecting those around them as if it were smoke. passive medicine. This month, a private school in Florida told staff that if they were to get vaccinated, they would not be able to contact the student because “we have at least three women affected their menstrual cycle after spending it. how long a person is vaccinated. “
In fact, it is impossible to experience any impact when being in close proximity to the vaccinated person, because there is no vaccine ingredient that is capable of leaving their body to be vaccinated.
The vaccines currently approved for use in the US instruct your cells to make a version of the mutant protein found on the coronavirus, so your immune system can learn to recognize it. . Different vaccines use different means of providing instructions – for Moderna and Pfizer, messenger RNA or mRNA; for Johnson & Johnson, an adenovirus is genetically engineered to be inactive and harmless – but the instructions are similar.
“It doesn’t look like a piece of a virus or it does what it does – it’s just a protein that has,” said Emily Martin, infectious disease epidemiologist at the Michigan School of Public Health. same shape. “The transfer of anything from a vaccine from one person to another is impossible. It’s just biologically impossible ”.
Microorganisms spread from person to person by multiplying. The vaccine ingredients and proteins are not renewable, meaning they cannot be spread. They are not even spread through your own body, much less for anyone else.
“They get injected into your arm and that’s where they stay,” said Jennifer Nuzzo, an epidemiologist at Johns Hopkins. “MRNA is picked up by your muscle cells near the injection site, cells use it to make that protein, the immune system learns about the mutant protein and gets rid of those cells. It is not circulating. “
It’s also not something sticking around. Messenger RNA is extremely fragile, which is one reason we never had an mRNA-based vaccine before: Scientists have had a long time figuring out how to keep it intact even for a while. the short amount of time it takes to provide its instructions. It will dissolve within a few days of vaccination.
Said Dr. Céline Gounder, an infectious disease specialist at the Bellevue Hospital Center and a member of President Biden’s transition advisory group on coronavirus. “The people who spread the virus are people with Covid. So if you want to prevent yourself or others from spreading the virus, the best way is to vaccinate against Covid infection ”.
This brings us to reports of women having irregular menstrual periods after being around vaccinated ones. Because one person’s vaccine cannot affect anyone else, the two events cannot be linked. Many things, like stress and infection, can disrupt your menstrual cycle.
Dr. Christopher M. Zahn, vice president of practice operations at the American University of Obstetrics and Gynecologists, said in a statement. “Such plots and false accounts are dangerous and have nothing to do with science.”
Some women have expressed concern that self-vaccination may affect their menstrual cycle. Unlike passive effects, this is theoretically possible and research is underway – but anecdotal reports could be explained by other factors and no research is available. found a link between vaccines and menstrual changes.
“There is no evidence that vaccines affect your menstrual cycle,” said Dr. Gounder. “It’s like saying just because I got my vaccination today, we’ll have a full moon tonight.”
