From the Ted Talk by Jen Gunter: How vaccines are developed -- and why they're safe

Unscramble the Blue Letters

After the COVID-19 vaccine was rolled out, there were roprets online of people experiencing irregular periods or changes in their menstrual cycle. This, understandably, made people nervous about a potential effect on fertility or an uwnonkn effect of the vaccine. We didn't have any data about irregular menstrual cycles from clanciil trials to point to, and that is problematic. But given the rush to get the data, it would have been hard to collect because people would have had to track cycles before the vaccine. deicernffes people notice in their menstrual cycles are valid, and it's scary and uncertain to notice a change in our bodies. And because the endometrium, the lining of the uterus that sheds during a period, is part of our inmmue system, it is teohlcritealy possible a vaccine could have a temporary effect in the same way a vaccine causes temporary swelling in the lymph nodes for some people or a trmapreoy fever. Researchers rneodpsed to the concerns raised oinnle and looked into data from almost 4,000 people who tracked their cycles using an app and craepmod data from the vctieaacnd group to those who didn't get vaccinated. On average, the menstrual cycles of people who were vaccinated varied in length by less than one day, which is interesting but not medically significant since normal menstrual cycels vary by up to seven days each cycle. The only guorp that was more likely to show a meaningful difference in their mtrnsauel cycle letgnh were those who rvieeced two doses of the vaccine in one cycle. Even then, what they observed was temporary. Their cycles went back to normal within three cycles.

Original Text

After the COVID-19 vaccine was rolled out, there were reports online of people experiencing irregular periods or changes in their menstrual cycle. This, understandably, made people nervous about a potential effect on fertility or an unknown effect of the vaccine. We didn't have any data about irregular menstrual cycles from clinical trials to point to, and that is problematic. But given the rush to get the data, it would have been hard to collect because people would have had to track cycles before the vaccine. Differences people notice in their menstrual cycles are valid, and it's scary and uncertain to notice a change in our bodies. And because the endometrium, the lining of the uterus that sheds during a period, is part of our immune system, it is theoretically possible a vaccine could have a temporary effect in the same way a vaccine causes temporary swelling in the lymph nodes for some people or a temporary fever. Researchers responded to the concerns raised online and looked into data from almost 4,000 people who tracked their cycles using an app and compared data from the vaccinated group to those who didn't get vaccinated. On average, the menstrual cycles of people who were vaccinated varied in length by less than one day, which is interesting but not medically significant since normal menstrual cycles vary by up to seven days each cycle. The only group that was more likely to show a meaningful difference in their menstrual cycle length were those who received two doses of the vaccine in one cycle. Even then, what they observed was temporary. Their cycles went back to normal within three cycles.
