Viral pandemics — H1N1 (from China), bird flu (from China), SARS (from China) and now the Wuhan virus (from China).15 Viruses.. 9 vaccines developed to prevent them… What’s the chance a Corona Virus Vaccine will be developed?
In fact a Coronavirus vaccine has been developed and is under test right now but a successful vaccine is many months away so shelter in place and follow all precautions. Look at the smallpox vaccine for an example of how a vaccine against a virus can be found. Same for rabies. OTOH a successful HIV/AIDS vaccine is still not available so we hope the Corona Vaccine is successful and it seems likely it will be but until the tests are over there is no vaccine available.
