There were/are a few, (serious scientists), who argued that should have been our M/O, from the very start of this pandemic. ie: Shield the elderly and vulnerable and just go about as business as normal. They argue that not only is vaccination not particularly effective, but that it also encourages the virus to mutate. Personally, I don't agree and much preferred the ''stay at home and hide'', method. Besides, MMR and Flu jabs have always seemed pretty effective?
