Menstruation can be affected by a multitude of factors, such as stress, thyroid dysfunction, endometriosis, or fibroids. If you have questions about your menstrual cycle, be sure to speak with your doctor.
Women seem to have more side effects after vaccination than men
A study from the Centers for Disease Control and Prevention, published in February, looked at the Pfizer-BioNTech and Moderna vaccines and found that 79 percent of the side effects reported to the agency came from women, though only 61 percent of the vaccines had been administered to women.
It could be that women are more likely to report side effects than men, said Sabra L. Klein, professor of molecular microbiology and immunology at the Johns Hopkins Bloomberg School of Public Health. Or, he added, women may experience the side effects to a greater extent. “We’re not sure which one it is,” he said.
If women have more side effects than men, there could be a biological explanation: women and girls can produce up to twice as many antibodies after receiving the flu and measles, mumps, and rubella (MMR) vaccines and hepatitis A and B, probably due to a mix of factors, such as reproductive hormones and genetic differences.
A study revealed that, over nearly three decades, women accounted for 80 percent of all adult allergic reactions to vaccines. In addition, CDC reported that most anaphylactic reactions to COVID-19 vaccines, although rare, have occurred among women.
And in a letter Published in the New England Journal of Medicine describing the experiences of people who had redness, itching and swelling that started four to 11 days after the first injection of Moderna’s vaccine, 10 of the 12 patients were women. However, it is not clear whether women are more prone to the problem.
If you have mild side effects, like a headache or a low fever, it’s actually a good thing, Klein said, because it means your immune system is kicking in. However, the absence of side effects does not mean that the vaccine is not working.
