Is it cases or symptomatic cases? I presume they were testing their sample regularly. Preventing symptoms would be a great outcome anyway, but it’s not the same as preventing cases.
That’s not good though... really could but a kink in establishing herd immunity until everyone is actually vaccinated.
b) It's likely that it is protecting against those. But hard to specifically prove that it's protecting against each and every symptom. I think the hope is that if you don't develop lung issues, you are unlikely to develop long term damage.
Maybe I'm misunderstanding the data here. It seems like we've only directly proven that the vaccine has been effective at reducing the normal symptoms (coughs, fevers) to the point where candidates don't seem to be prompted enough to go get tested anymore. It doesn't directly prove those candidates didn't get covid.
Still, I'll use this vaccine if I can't get Moderna in time. The safety profile looks great.
What does that mean? Don't both vaccines work exactly the same? Both are mRNA vaccines.
I can't say anything about these vaccines, but there is such a thing as a non-sterilizing immunity, that would prevent you from developing COVID-19 but still be infected and able to spread SARS-CoV-2.
What does this mean?
As I understand it, all vaccines ever do is provide you with a prepared immune system for when you do get infected.
