@Duine I've seen that 4chan screenshot a while back. I think the post is real, but take the Moderna engineer claim with a huge grain of salt, given the completely anonymous nature of 4chan.

But if children of the vaccinated are going to be sterile, then we won't know for almost another two decades and even then, fertility rates have been dropping like a rock and it really gets talk about. Sperm counts have been decreasing dramatically in the past few decades. So you are going to have to take that into account.
