According to the Journal of Obstetric Gynecologic & Neonatal Nursing, women generally have a higher immune response to vaccines. These data support results from other vaccines. Women had received 61.2% of the available vaccines.Īlso, nearly all reported anaphylactic allergic reactions to the Pfizer and Moderna vaccines occurred in women. In February 2021, the Centers for Disease Control and Prevention (CDC) released a report on safety data from more than 13.7 million vaccine doses given in America.Īccording to the study, 79.1% of the reported side effects came from women.
How Does Sex Affect COVID-19 Vaccine Side Effects?Īccording to available data, women more often reported side effects to the COVID-19 vaccine than men.

For the Pfizer-BioNTech vaccine, 88.7% of people ages 18 to 55 reported local reactions, and 82.8% reported systemic reactions.The data held true for local reactions (pain, swelling, or redness at the injection site) and systemic reactions (headache, fatigue, muscle pain, fever/chills, and nausea).
