Link between fertility and Covid-19 vaccination investigated

14 October 2022 – Swissmedic has recently received enquiries from the public and media representatives concerning a possible link between COVID-19 vaccination and fertility. Therefore, Swissmedic and ten partner authorities have reviewed indications of a possible link between fertility and Covid-19 vaccination. Investigations have included countries with significantly higher vaccination coverage than Switzerland. The partner medicinal product regulatory authorities are responsible for a population of around 800 million people. None of the countries in question have seen or evaluated a signal related to Covid-19 vaccination and fertility. From a scientific perspective, neither the published literature nor global market surveillance yield any indication that mRNA vaccines could impair human fertility. Furthermore, Swissmedic has not received any safety signals from within Switzerland.
