Overall, the median onset of local reactions in the vaccine group was 1 to 2 days after either dose, with a median duration of 1 day after onset. No grade 4 local reactions were reported. Redness and swelling were more common after dose 2 than dose 1 or 3. Injection site swelling following either dose was reported less frequently. Redness was reported slightly more frequently in the older age group than the younger age group (10.9% vs 7.5% after dose 3). Injection site redness was the second most frequently reported local reaction. After dose 1, the older age group (2 – 4 years) reported pain/tenderness more frequently than the younger age group (6 – 23 months) (30.8% vs 16.6%) a similar pattern was observed after dose 2 and 3 (31.0% vs 15.0% and 26.7% vs 16.0%, respectively). Pain/tenderness at the injection site was the most frequent and severe reported solicited local reaction among vaccine recipients. Vaccine recipients reported similar rates of local reactions after dose 1 and dose 2, but slightly lower after dose 3. Local reactions were reported by half (48%) of vaccine recipients and at higher rates than placebo recipients. "I think because it rises to a level of importance to the public," she says, "it's something that should be included.Persons Aged 6 Months – 4 Years Local Reactions Ultimately, Edelman thinks changes to menstruation probably should be added as a possible minor side-effect of the vaccines, along with headaches and sore arms. Bianchi hopes that the additional research can look at a more diverse population than those that use the app, and also start to nail down other reported side-effects, including heavy periods and breakthrough bleeding. Last summer, the agency funded five studies including Edelman's work, and the results of the other researchers should provide more data. "The risk of COVID-19 disease in pregnant women is incredibly serious," said Edelman, who has watched pregnant women end up in intensive care because they're not vaccinated.īianchi says that the NIH should have more data on how vaccines alter menstruation in the near future.

Given that relationship, it's entirely possible that triggering the immune system through vaccination might change a person's cycles. Edelman says the immune system and the reproductive system are linked, and some signaling immune cells also can affect the body's natural clock. Researchers still aren't exactly sure why the changes occur. The immune and reproductive systems are linked "I think the beauty of the study is that it does affirm what individuals were reporting," she says. Nevertheless, she adds, it does prove that the vaccines are affecting menstruation independently of other possible factors such as pandemic stress. "It's really nothing to get alarmed about," Bianchi says. In other words, people who were vaccinated experienced - on average - a slightly longer menstrual cycle around the time of their first and second doses. "We see a less-than-one-day change in their menstrual cycle length with vaccination," Edelman says. Looking at data from 3,959 individuals, they were able to see a small shift in the time between bleeding. Diana Bianchi, director of the Eunice Kennedy Shriver National Institute of Child Health and Human Development, which funded the work.Įdelman's team took data from a popular app known as " Natural Cycles," which people can use to track their menstrual cycles. "There was a need to be able to counsel women on what to expect," says Dr.
