A recent Israeli study has concluded that women who take COVID-19 vaccines are two times more likely to develop side effects, as compared to men.
A new Israeli study published in the peer-reviewed journal Vaccines showed that women experience nearly twice as many adverse events following inoculation with the Pfizer COVID-19 vaccine as men.
The study was conducted by a team of scientists from the School of Public Health at the University of Haifa using data from four sources: the Health Ministry database of adverse events, the national cross-sectional survey based on an internet panel, and from two different cross-sectional surveys among employees of a large company. The data was collected between December 2019 and September 2021. The researchers found that women reported side effects following the first, second, and third vaccines at a rate 1.9 times higher than men.
Furthermore, the research recommended that different doses of the vaccine for men and women should be explored.
Other findings included that women experienced a greater rate of pain in their entire arm: seven times higher than that of men for the first shot, 4.2 times for the second, and 4.1 for the third. Weakness was 30 times higher for women than men after the first dose, 2.6 times after the second, and 1.6 after the third. Lead researcher Professor Manfred Green explained to JNS that the 30% is a result of the small sample size: one male experienced weakness compared to 23 females, according to the data.
