The European Medicines Agency (EMA) states that Pfizer vaccine can be safely stored at refrigerator temperature for up to a month.
Recently, there have been several studies on whether Pfizer vaccine is easier to store than it has been until now. The vaccine, which has become the favorite in the European Union, first had to be stored in special freezers stored at 60 to 90 degrees Celsius.
Later, the EMA concluded that it could be kept in regular refrigerators, and now the Medicines Agency states that regular refrigerators last as long as the vaccine has not been stored for more than a month. The flasks must be unopened.
This makes vaccination much easier. The need to store in extremely cold temperatures was one of the reasons why vaccines like AstraZeneca, among other things, have been the preferred choice in the Covax collaboration.
Storage problems have also posed some challenges in Norway, but Deputy Director of Health Espin Nakstad does not believe that it will be necessary for the Norwegian vaccination to facilitate the storage of the vaccine.
This is good news, although it may not be important for the Norwegian vaccination program. But that means you get more flexibility in municipalities, and the risk of vaccination doses falling off is less, Nakstad told NTB.
