Challenges...
Getting the vaccine from the factory to people’s arms could pose some major challenges.
Like Moderna’s vaccine, Pfizer and BioNTech’s preparation is based on mRNA, which falls apart unless it’s kept in a deep freeze. As a result, the vaccine will have to be chilled to minus 70 degrees Celsius until it’s ready to be injected. Pfizer is building boxes that will keep the vaccines cold as they’re being transported. In addition, like most vaccines currently in trials, it requires two doses. Ensuring that people return after three weeks for their second injection will add an extra layer of complexity to the vaccine’s distribution.
