It sounds like a myth and was laughed away for a long time, but the grown cup size that countless women claim to experience just after coronavaccination may be scientifically explained.
This week, international news media reports that the Australian Department of Health has officially included enlarged lymph nodes as a side effect, following the findings of American scientists.
For months there have been claims from women who suddenly have a larger cup size. The effect even has a name: the Pfizer boob job. “I can say from my own experience that Pfizer does make your breasts bigger,” someone writes. “I feel my breasts are growing, or am I hallucinating?” , asks another.
Some note that their lymph and mammary glands are swollen. The Australian government has now officially confirmed that first as a rare side effect, which may explain the findings on breast size.

In America, where the vaccination campaign is in a more advanced stage, a mammogram is often applied after vaccination above average. Many women mistakenly think of cancer, says Laura Esserman, director of the University of California San Franciscos Breast Care Center. In reality, its about swollen glands. “Im sure it concerns hundreds of thousands of women.”
Research by the Radiological Society of North America showed that vaccination swollen glands are an important side effect that doctors, patients and cancer researchers should focus on.
Ex on the Beach
Hoongelach included a Flemish participant of TV show Ex on the beach, Olivia Talar. “I heard your cup size can increase to two sizes after the Pfizer vaccine. Thats when I had a slight breakdown. Is there anyone who knows a little more about this?” , she wrote on Twitter. “I hope this is a joke.”
Yes, epidemiologist Pierre Van Damme (UAntwerp) responded immediately. “I think this is utterly nonsense,” says Van Damme. “It may be that the axillary gland is slightly swollen after an inoculation, but that will not immediately lead to an enlarged chest circumference.” According to him, the mammary glands are “not involved in the immunological process.” So women can definitely feel something or notice something, but a really larger outline is unlikely, according to this expert.
Anyone who notices difference and has gained hope for an ever-larger bosom will be deceived. It is still unclear how long the larger breasts last — probably up to four weeks — but the effect is temporary anyway.
The lymph nodes are completely harmless. The phenomenon only indicates the production of antibodies. “That can make the breasts grow for a short period of time after a coronavine vaccine,” said a writer of the Nautilus science magazine. “But its not a cause for concern.”
However, according to experts, there are other anecdotal stories of women that need to be better sorted out. Americas best-known gynecologist, Jen Gunter, who writes regularly in The New York Times and also wrote the books The Menopause Manifesto and The Vagina Bible, calls for more research of stories about changed menstrual periods, which are increasingly popping up.
Researchers at the University of British Columbia also find that research into side effects of women, such as the stories about women in the transition that are suddenly being postponed, is largely lacking. Female specific studies account for 6% of literature, with mens research that percentage is 40%. The scientists ask for more research, but do stress that vaccination should continue at the moment and that the effects on menstruation are presumably temporary.
