That really depends on the vaccine. What you are referring to is sterilizing immunity. Ie you don’t get sick at all and neither can you pass it on. The hopes for this kind of a vaccine aren’t very high.
- xg15 6y ago> The hopes for this kind of a vaccine aren’t very high. Why actually? SARS2 is extremely contagious and it attaches to a receptor which is involved in various vital systems in the human body and can cause a wide range of life-threatening symptoms. This is what makes this virus so dangerous. However, apart from that, it's an "ordinary" coronavirus: It's not a retrovirus like AIDS and does not mutate as fast as rhinoviruses. I've not read any news about serious complications in vaccine development either. So what would make developing a vaccine so particular hard here? > What you are referring to is sterilizing immunity. Why would this be a requirement? The point of herd immunity is that it also works if less than 100% of the population is immune, as long as the probability of transmission is lowered enough to effectively stop the spread. A vaccine that would lower the probability of infection enough seems to be able to archive the same.
