Pfizer will need to use ultralow temperature freezers and thermal shipper storage for its COVID-19 vaccine candidates, according to comments made by … Room Temperature for Vaccination: Once the vaccine is removed from the refrigerator for administration, it can be kept at room temperature conditions for up to 12 hours. Vaccines made from mRNA can be made much faster than older vaccines could, explains Margaret Liu, a vaccine researcher who chairs the board of the International Society for Vaccines and specializes in genetic vaccines. Since there will be limited vaccine doses at first, immunization managers across the country will need to have plans to distribute any and all vaccine doses that are available. Room Temperature for Vaccination: Once the vaccine is removed from the refrigerator for administration, it can be kept at room temperature conditions for up to 12 hours. “All those steps need to happen, and [when] they do, then people like me and many other infectious disease experts will line up for the vaccine,” Dr. Boucher says. But even with the stabilized building blocks and lipid coating, the mRNA could still fall apart easily, which is why the vaccine is frozen. Just days ago Pfizer and BioNTech announced that their Covid-19 vaccine has proven 90% effective against the novel Corona virus.
