Since some vaccine hesitancy is centered around a theory about fertility concerns, maybe seeing anecdotal evidence of successful post-vaccine and post-disease pregnancies could help calm anxieties until a proper study is done. (I see a couple of posts on this topic, but not with this precision or a poll to help count and compare cases.)

Consider the full text of the answers to be:

Pregnant 2 weeks post vax: I had the complete vaccine and successfully became pregnant at least two weeks after vaccine completion.

No pregnancy after vax: I had the vaccine and tried to conceive but haven’t yet (with no other known infertility factors).

Pregnant after recovery: I had covid-19 and successfully became pregnant at least two weeks after recovery.

No preg after recovery: I had covid-19 and tried to conceive but haven’t yet (with no other known infertility factors).

Details of your experience are welcome in the comments!

For what it’s worth, it seems the proteins of concern share a sequence of only 4 out of over 500 amino acids. Since only 20 amino acids exist, this is unlikely to cause a problem. It would be like saying two 500-letter words are the same because they share a set of four letters. If the immune system attacked based on so short a sequence, it would be surprising it didn’t attack much more throughout the whole body. (Hemoglobin apparently shares a sequence of 5 amino acids with the spike protein, for example.)

But emotions aren’t always rational, and in the absence of a proper study, maybe anecdotal evidence from even anonymous users can help.
