ATLANTA (CNN) — It's the claim that's suddenly everywhere: The COVID-19 vaccine is going to make women infertile!

Richard Beigi: There's never been any vaccine that's been linked with infertility.

There is no clear scientific reason to think the new vaccine would cause fertility problems in adults.

Just like getting the flu after a flu shot, these events were very likely to have already been under way when women received the vaccines, and then they became clinically recognized after the vaccine was given.

Pregnant women weren't part of the original clinical trials, but this year over 100,000 pregnant women have received one of the vaccines — mostly the mRNA vaccines of Moderna and Pfizer, but also some women have gotten the J&J vaccine.

We know this because 106,000 women who received the vaccine and signed up with government's v-safe program said they were pregnant.

That's why we're looking at bigger groups of pregnant women who have taken the vaccine and comparing them to what we already know happens to pregnant women — and at what rates — before we had these vaccines.

As the data comes out, what we're now seeing in these thousands of women who took the vaccine is that their pregnancy outcomes are no different than the population of pregnant women who did not get one of the vaccines.

I would think that hearing that thousands of pregnant women who have taken this vaccine and there are no signs of problems — I would hope for some people with concerns, that would be reassuring.

And I am undoubtedly going to get my two teenage girls immunized when the vaccine is available in my area.

There was absolutely no reason to think there's going to be new problems in this age group
