Still waiting for you guys to let me know what the word "prevent" means in this context.
Suffice it to say that if you believe the polio vaccine "prevents" polio, then in summer 2021 it would have been entirely accurate to say that the COVID vaccines "prevent" COVID.
Not sure why you would think we can't determine sex by scientific means.
If I were to take a guess, I'd say it's because you probably think sex and gender are the same thing.
Prevent means exactly what it says. It either prevents it, helps to prevent it, or does not prevent it. If it does one but is advertised as the better version then it is a lie. Kind of like telling your wife you stopped over for a few drinks with the neighbor and left out the part where you had sex. It's either the truth or a distraction to the lie.
