Calm down old man, we're just talking here. No need to get all fuckity-fuck with your words of wisdom.
Being the 95% effectiveness rate is vs sickness/symptoms, not infection, this should be a relevant question.
Why is that even a question? You missed biology in school?
Because a statistical shift as such may explain what's happening around us. And, incredibly, I scraped together the patience to put up with Internet randos harping about how stupid my question, and by extension myself, must be.
i) There is no vaccine blocking infection - how the fuck would that be scientifically possible?
I'm not prepared to explain the apparent 60% resistance boost from the Israeli study I read about. Maybe they're making it up. Perhaps there was a bizarre chain of events giving such a result. Or maybe there is a biological event neither of us is familiar with at play. Consult your text of choice.
ii) There is no vaccine preventing you spreading it - how the fuck would that be scientifically possible?
I would guess the immune system you mention that "is hard trained to kill the buggers quickly" might reduce the shed rate of vaccinated carriers. Maybe this would approach a statistically trivial number of downstream infections.
Of course none of the event firing chances are reduced to zero. But are they sufficient to alter the course of the pandemic? Does India now have an army millions strong that are vaccinated, still subject to infection, unlikely to develop symptoms, will then go on mingling instead of realizing they are infected and quarantining, then spread further infections?
I think that's a reasonable question but, please, accept my sincere apologies if you already know the answer and reading this disturbs your interwebs harmony. I'll show myself back down the mountain.
