This is the issue with misinformation, its usually based on a legitimate concern that was suppressed instead of answered; There was an issue with a protein in placental? tissue being similar to the spike protein, this is why the vaccine isn't recommended for pregnant women unless they are at high risk.
Now the layman knows the spike teaches the immune system what to attack, and puts two and two together, and assumes the vaccine will make all women sterile. I would love to put this argument down when i see it, but no one has explained why this isn't the case.. so I'm left with "surly they wouldn't do that" which is not a compelling argument.
