Please stop with this misleading hypothetical question narischkeit. No, the vaccine does not effect fertility. Ten months of millions of women taking it has proven that much. It is not “too soon to say”, it’s literally false.
COVID, on the other hand, can potentially impact fertility. So perhaps if someone doesn’t take the vaccine, gets COVID, and now can no longer have babies they’ve been oiver on pru u’revu? Maybe they are also oiver on Lo Sa’amod by convincing someone not to get vaccinated and then watching them get hospitalized?
