A question or two:
It seems like many of those who are becoming severely ill and dying are doing so from contracting pneumonia as a "side-result" of the ChinaVirus.
Will having had a "pneumonia shot" (vaccine? supposed good for 7 years) in the past offer any protection against this?
Anyone have any idea?
I don't know. The three main identifiable risk factors are Hypertension, Diabetes, and Coronary Disease.
Age may be a factor, but the three above are more common as people get older, so that may be a red herring.
Some have postulated that the pneumonia is a form of pulmonary edema brought about by an overly intense immune response, similar to a Cytokine Storm.
Certainly, anything which might prevent an opportunistic bacterial pneumonia can't hurt, but may not provide any protection from the virus, itself.
