Agreed. In my previous post, I asked the question about genetically altered strains of smallpox -- and would our vaccine be effective.
Thoughts?
I suspect that if the mode of virulence is the same, then previous vaccinations would be effective against even a genetically altered form of the virus (although this is far from certain).
There is also considerable question in the mind of immunolgists, as to whether or not those vaccinated against smallpox would maintain their immunity for so long without a booster. Precious little experience in this area.
