There is no relation between reduced immunity 🤧 and 🩸🩸🩸 periods. Period.
If it really was, then we’ll get be getting all sorts of viral & bacterial infections during menses and the ensuing immune system reactions such as fever, cough etc. If you cannot scientifically explain reduced immunity during periods, then don’t spread misinformation about not getting vaccinated during cycle times because we cannot have ladies delaying vaccination because of their menstrual cycle, considering the critical situation we are in.
