It is possible to transport and store bottles with undiluted frozen Pfizer/BioNTech vaccine for two weeks in usual refrigerating chambers for pharmaceutical drugs with temperatures 15-25 degrees below zero. The mitigation was approved by U.S. Food and Drug Administration (FDA).
Pfizer/BioNTech renewed the recommendations on the basis of data received during nine months since the beginning of the drug’s development.
Earlier, it was reported that the storage of the vaccine is possible only with deep-freeze temperature from 60 up to 80 degrees below zero to prevent the accelerated destruction of the drug’s structure. It was allowed to store the vaccine in usual refrigerating chambers only five days before the use of it.
After the dilution, the drug can be stored at the refrigerating chamber or indoor temperature for not more than six hours.
Meanwhile, the vaccination from Covid-19 began in Ukraine on February 24. The first person to receive the vaccine was Yevhen Horenko, a resuscitator at the Cherkasy Regional Hospital.
Despite the fact that President of Ukraine Volodymyr Zelensky stated that CoviShield is ‘one of the best vaccines’, the majority of medics of Oleksandrivsky hospital of Kyiv, who work with Covid-19 patients, refused to be injected with it.
Today, the Health Ministry of Ukraine reported seven ‘unfavorable events’ after the first vaccination with CoviShield.
