...may prove to be of value in another way besides preventing infection.
Currently, there are victims of the SARS-CoV-2 that are experiencing lingering effects even after they win the fight and survived the infection. These victims will have to be followed as to their wellness in regards to the protection provided by the vaccines. In other words, are vaccine recipients immune to the lingering effects once they have recovered from any exposure?
Defeating the lingering effects of exposure to the virus and the variants is just as important to surviving and being immune to end any disability produced by exposure. It is my estimate the vaccines will prevent the long term effects of cell damage. If body cells are protected or at least minimized from invasion by the vaccines the long term effects will end or be diminished.
There are additional vaccines in the pipeline, too.
