Even as medical scientists have detected a new, potentially more contagious variant of the coronavirus that also may pose greater risks to children, the high hopes for a faultless roll-out of Covid-19 vaccines are getting tempered with unhappy doses of reality.
Roughly 1 million Americans have been vaccinated already, most with a product from Pfizer and some with a vaccine from Moderna.
That is good news to start. It may, however, also start to raise concerns about the plans to inoculate more than 300 million Americans, many with a two-shot vaccine. That’s because Trump Administration officials had forecast with great confidence in recent days that 20 million Americans would be vaccinated before 2020’s end.
