Why A COVID-19 Vaccine That's Only 50% Effective Could Still Help Stop The Pandemic
As we get closer to a COVID-19 vaccine, it's exciting to imagine a day when the virus is gone. But a vaccine will not be a magic bullet. In fact, it may be only about 50% effective. Dr. Anthony Fauci, chief of the National Institute of Health and Infectious Disease, has tried to set realistic expectations when discussing the importance of a vaccine. "We don't know yet what the efficacy might be. We don't know if it will be 50% or 60%," Fauci said during a Brown University event in August."I'd like it to be 75% or more," Fauci said, but he acknowledged that may not be realistic.

China Says No Need To Vaccinate Entire Population Against Covid-19 At This Stage, Only Frontline Workers
Not everyone in China will need to get vaccinated against Covid-19, according to the country's top medical official, as Beijing looks to prioritize frontline workers and high-risk populations in a move that underscores rising confidence among policy-makers of their ability to contain the virus.
