Google it. This is from end of April, but I think most of the concerns are still valid. It isn’t like we have not been trying to make a Coronavirus vaccine before.
“We’ve tried getting vaccines for coronaviruses before, particularly SARS and MERS. We just haven’t done it yet. We think this is going to be a hard effort.”
Nothing in either of those articles says a vaccine is “unlikely to work.”
There is a lot of concern that finding a vaccine will take more time than we would like. There is concern that it’ll have to be taken annually or that it will not be 100% effective.
There is some concern that we won’t find one. That is possible. But likely? If anyone is saying that it’s likely that we won’t find one that works (and I haven’t read anyone saying that) they’re in the minority.
