If a link between vaccination and menstrual changes is confirmed, this will allow individuals seeking to get vaccinated to plan in advance for potentially altered cycles, Dr Male wrote in the BMJ editorial.
Though the link is currently unproven, the aforementioned reasons outline how the vaccine could be causing changes to periods – but these changes are not anything to worry about, reproductive specialists say.
While painful or unexpected periods can be distressing, they are not a sign of any long-term harm.
Doctor Randi Hutter Epstein at Yale School of Medicine wrote “So far, there’s no data linking the vaccines to changes in menstruation. Even if there is a connection, one unusual period is no cause for alarm.”
