Part of me wants to believe that Covid-19 is scaring the pants off everyone. But some family members are anti-vaxxers (the pejorative term for vaccine hesitancy) and I see their attitude to the present virus, I am less hopeful.
My medical friends are certain a vaccine will emerge in the next 18 months, and for good reason. There is a full court press by many labs and governments and science knows so much more than it did a decade ago.
