from Pfizer on Andrew Mar show just now .
When asked whether any vaccines introduced would just reduce the symptoms of covid, and leave a person infectious or would any vaccine eradicate the infection in any individual . He said that at present we do not know the answer to this - but hopefully the person would not be infected anymore - but said that maybe only around 50% of the infection would be eradicate along with a reduction in symptoms, ( a bit like flu, really, i guess).
If this turns out to pass then many people will remain infectious, after vaccine when they have reduced symptoms.....bad news for us ALL, but good news for those company's that make vaccines and testing kits , i guess.
