The CDC and big pharma have not been able to come up with a vaccine yet that they feel will be effective for the corona virus. We hear from them that it normally takes a year to break down the genetic structure of a virus, and then be able to construct a vaccine from that information. However, they expect us to believe that, every year without fail,  they soothsay which genetic variety of the flu will be prevalent, and make vaccines, in advance, for the flu, and pneumonia.
