A cure is extraordinarily unlikely. We don't have cures for smallpox, rabies, polio, measles, the flu, the mumps, pertussis, German measles, and well, you get the idea. Cures for viruses just aren't in our arsenal yet, and there is none on the horizon for COVID or any other viral scourges. What we do have, in many of these cases, is an effective and safe vaccine. I believe that this is what we will have for COVID too, though we may not know for some time for whom it is most effective and what the side effects may be. I know enough about vaccines to have confidence that an effective vaccine is likely to be helpful--either by making it very unlikely that a vaccinated person will come down with the disease or else will get a much milder case. At the moment, we have a large number of candidate vaccines in development, with quite different mechanisms to create purported effectiveness. That is why I won't be first in line--as an older person living with an even older spouse who is immunocompromised, I'll be waiting for data on which of the candidate vaccines promotes the most robust immunity among the elderly. But, once the data is in, I won't care whether the pharmaceutical company took government money or not. Science is science...
