- Concerning COVID-19, possibly the best to be hoped for over the next many months will be the emergence of ‘herd immunity’. ‘Herd immunity’ will occur when approximately two-thirds of the population has been in contact with the coronavirus, creating enough antibody protection to severely slow its spread. Nevertheless, that will still leave one-third living under the sword of Damocles. Randomly, someday, somewhere, somehow, they may be touched by COVID-19 with possibly dire consequences. At least, that will be case until an effective vaccine has been created.
- This is where the science becomes fascinating, but also complicated. Apparently, there may be development of several different makes and models of COVID-19 vaccine. A standard vaccine uses a weakened version of the offending virus to prod a body into launching an overwhelming defense posture. A new ‘platform’ approach, with a shorter testing and approvals span, modifies a known closely related virus ‒ maybe even from the animal kingdom, since there are untold numbers of viruses with an incredible diversity of characteristics ‒ to become a harmless copycat of the latest interloper, in order to engage the body’s immune system and set in place a rapid deployment system to fight off future attacks.
