Officials with Operation Warp Speed, the federal government program to fast-track the development and delivery COVID-19 vaccines, anticipate that 40 million doses of the Pfizer and Moderna products will be available by January, enough to vaccinate about 20 million Americans. The majority of American adults will likely have access to the vaccine by spring 2021 or early summer, according to most estimates.
However, even after the vaccines are in circulation, people should not expect a sudden return to normal. …
[A] person who gets one of the two available vaccines has a 95% chance of being protected against serious illness, personally, but they may still be able to contract the virus and spread it to others. That would mean a greater opportunity for the pandemic to continue despite vaccine availability.
