Research by Yoppie, the pioneers of personalised period care, has found that a quarter of women are concerned about the impact of the COVID-19 vaccine on their menstrual cycle, as well as their fertility.

Yoppie’s research found that 11% of women said they have seen a change to their menstrual cycle since having the COVID-19 vaccine, with changes including, but not limited to, a heavier flow or a change in the frequency of their period.

Yoppie also found that 26% of women were worried about how the COVID-19 vaccine might potentially impact their menstrual cycle.

These irregularities caused by the COVID-19 vaccine have also prompted concerns that it may also impact fertility, with Yoppie’s research again finding that this is a concern for 26% of women.

Despite these concerns, many women are still keen to get themselves vaccinated. Yoppie asked if worries surrounding either their menstrual cycle or fertility would prevent, or had already prevented them from getting vaccinated against COVID-19. Just 9% answered yes, with 91% still intending to get the COVID-19 vaccine if they hadn’t already done so.

Founder of Yoppie, Daniella Peri, commented:

“The menstrual cycle is an incredibly personal and unique thing for every woman and so it makes sense that any changes as a result of a COVID-19 vaccine will also differ greatly between one woman and the next. It’s also natural that any changes to our cycle might cause an initial degree of alarm or worry.

The important thing to remember is that you’re not alone and if you need some reassurance, don’t be afraid to seek medical advice from your GP.”
