in fact, the function of the vaccine is not so important anymore. It is still important that which country can produce the first vaccine to prevent this covid epidemic as soon as possible.https://www.cnbc.com/2020/11/09/covid-vaccine-pfizer-drug-is-more-than-90percent-effective-in-preventing-infection.html#close
As you know, this is the economic virus. If you let people live with such epidemics for another year, the economy would have really collapsed before you were excited
Hopefully Pfizer has the resources and the energy to be able to announce the vaccine sale in Q1 2021, which is really the good news we want to look forward to.
