Period late after vaccine

9 May, 2021


I have a very regular cycle and am not usually more than a day or 2 late to get my period. Since getting the corona vaccine I have not had my period (6 days).

Can me and my husband be together? Do I need to do a daily bedikah?

I’ve seen this begin to be reported but at the moment there is not much research as too how long and the details of this side effect.


Medical consensus is that the Corona vaccine and booster may slightly affect a woman’s cycle, but that any effects are short term.

If you have observed all of your vesatot, including (at minimum) a bedika on or following your veset kavua (if you have one) or onah beinonit (if you don’t), then you and your husband may resume relations as usual and no further steps need be taken. In that case, though, you should keep an eye out for signs of impending bleeding such as staining, and consider abstaining if you have them.

Please let us know if we can be of further assistance.
