So, about that vaccine…

StatNews.com reports it’s time to face reality: There won’t be a vaccine for coronavirus before Election Day, and one before the end of the calendar year looks highly unlikely, too.

It is important to note that, to date, none of the vaccines being developed for the U.S. market has been proven to be effective in preventing Covid-19 disease. Early stage clinical trials have shown what appear to be promising signals; multiple vaccines have triggered production of important antibodies in people who have been immunized.

But data generated in a few hundred people aren’t enough to determine whether a vaccine will actually fend off illness. That answer comes from large, Phase 3 trials, five of which are now underway in the United States. Their findings will ultimately tell us how soon vaccines may start to be rolled out to the masses.
