  • Work to distribute the experimental COVID-19 vaccine developed by Pfizer Inc and BioNTech SE is gearing up after the companies announced successful interim data earlier on Monday , but it will not be coming to local pharmacies for the general public any time soon.
  • The main issue is that the vaccine, which is based on a novel technology that uses synthetic mRNA to activate the immune system against the virus, needs to be kept at minus 70 degrees Celsius (-94 F) or below.
  • The vaccine of Moderna Inc, which is working on a vaccine based on similar technology, does not need to be stored at such a low temperature.
