COVID 19 VACCINES AND THEIR EFFECTIVENESS
I had assumed that the vaccines under development for Covid 19 would have 90% or more effectiveness. Dr. Fauci today said a new vaccine for Covid 19 would likely be between 50 and 60% effective, like the vaccines for the flu, not like the vaccines for the measles. That may mean we are looking at a very long and slow road back with lots more mask wearing, more social distancing and limited social interactions. If so we will have to learn to be assiduous about prevention not just today, and tomorrow, but next year. We are going to need to work from home wherever possible, and learn to do distance learning much better, and develop new lifestyles about our social and work and family lives.
If it proves accurate, this is pretty heart breaking as I was expecting life to return to normal by next spring or early next summer. Stay well and take good care of yourselves.
