There is no AiDS vaccine. There is no vaccine for flu and many other pathogens. I’m curious why so confident a SARS-CoV-2 one will arrive?



Just 50% of Americans say they will take such a vaccine, and a lot of that skepticism lies in the speed at which one is being pursued. It seems many people understand it takes years to develop safe and successful vaccines. Resistance to a vaccine will ebb as a function of time passing with it being safe and working. This is a large part of why I feel waiting for a vaccine instead of seriously changing our approach to getting the outbreak under control, is a bad idea.

Huh?  There is an influenza vaccine.

I generally share akiddoc's optimism.  There are currently almost 200 vaccines in development, and over a dozen that have started testing in humans.    While the chances of any given vaccine working are not great (especially the ones pursuing novel technologies), the chances that at least one of them will be safe and effective are pretty decent.

I would not be surprised if there is waning immunity and people will have to get booster shots.  Hopefully over time vaccines will be developed with longer-lasting immunogenic response, but for the moment, I think even the modest goals set by the FDA (>50% efficacy) will make a very big difference in terms of helping control the pandemic.
