That's not my impression. My impression is that official sources are claiming that it reduces the chances that you get it at all, and maybe reduces the chances that you'll pass it on as well.

I have never (that I recall) seen an official source saying what you claim. (Mind you, I'm not saying that you're wrong in your assessment of the effectiveness of the vaccine. I'm not even saying that you're wrong in your read of what officials are claiming - just that I have never seen it.)

Can you point me to someone official making that claim? And, what country are you in?
