O'Connor said Biden, 80, also was vaccinated several weeks ago against the respiratory illness known as RSV. Kevin O'Connor, said in a memo that Biden received both shots on Friday. Klein said.WASHINGTON – President Joe Biden has gotten the updated COVID-19 vaccine and annual flu shot, the White House said Saturday. “Women have greater immunity, whether it’s to ourselves, whether it’s to a vaccine antigen, whether it’s to a virus,” Dr. These robust immune responses help to explain why 80 percent of autoimmune diseases afflict women. But research now shows that 15 percent of genes escape this inactivation and are more highly expressed in women. Historically, immunologists believed that only one X chromosome in women was turned on, and that the other was inactivated. Many immune-related genes are on the X chromosome, of which women have two copies and men have only one. Genetic differences between men and women may also influence immunity. Among other things, testosterone suppresses the body’s production of immune chemicals known as cytokines. Klein said, “is kind of beautifully immunosuppressive.” The flu vaccine tends to be less protective in men with lots of testosterone compared with men with less of the sex hormone. Exposure to estrogen causes immune cells to produce more antibodies in response to the flu vaccine, for example.Īnd testosterone, Dr. Sex hormones including estrogen, progesterone and testosterone can bind to the surface of immune cells and influence how they work. These differences are often most robust among younger adults, which “suggests a biological effect, possibly associated with reproductive hormones,” she said. They often mount stronger responses from immune fighters called T cells, too, Ms. Research has shown that, compared with their male counterparts, women and girls produce more - sometimes twice as many - infection-fighting antibodies in response to the vaccines for influenza, M.M.R., yellow fever, rabies, and hepatitis A and B. Another study found that between 19, women accounted for 80 percent of all adult anaphylactic reactions to vaccines. and other institutions found that four times as many women as men between the ages of 20 and 59 reported allergic reactions after receiving the 2009 pandemic flu vaccine, even though more men than women got those shots. In a 2013 study, scientists with the C.D.C. “This sex difference is completely consistent with past reports of other vaccines.” “I am not at all surprised,” said Sabra Klein, a microbiologist and immunologist at the Johns Hopkins Bloomberg School of Public Health. ![]() ![]() ![]() researchers reported that all 19 of the individuals who had experienced such a reaction to the Moderna vaccine have been female, and that women made up 44 of the 47 who have had anaphylactic reactions to the Pfizer vaccine. Nearly all of the rare anaphylactic reactions to Covid-19 vaccines have occurred among women, too. Among the side effects reported to the agency, 79.1 percent came from women, even though only 61.2 percent of the vaccines had been administered to women. In a study published last month, researchers from the Centers for Disease Control and Prevention analyzed safety data from the first 13.7 million Covid-19 vaccine doses given to Americans. Kendeffy observed among her co-workers are playing out across the country. “I wouldn’t change a thing, because it sure beats the alternative,” she said. But “clearly, us women suffered a severity of the side effects.” She felt better after 24 hours, and is thrilled she got the vaccine.
