Delay in periods after vaccination is temporary
Scientists found that women’s period was 0.64 days late after getting the first vaccine. At the same time, when the second vaccine was administered, the period was delayed by 0.79 days. For women who had not been vaccinated, their period came at their normal time. There were also 358 women in the vaccinated group, whose period cycle increased by 2.38 days.
