US pharmaceutical giant Pfizer is planning a new version of its coronavirus vaccine that can be stored in a standard freezer and comes diluted and ready for use, its CEO told AFP on Friday.
The vaccine developed by Pfizer and Germany’s BioNTech is already a mainstay in international efforts to control the pandemic — and in Israel it has been nearly exclusively used to vaccinate the population — but it is a challenge to ship and protect.
The current version must be stored at minus 70 degrees Celsius (minus 94 degrees Fahrenheit), limiting its distribution to specially equipped vaccination centres.
But Pfizer’s chief executive Albert Bourla told AFP in an interview that a new version is in the pipeline and that he was optimistic the vaccine will also prove effective against new virus variants.
Bourla said Pfizer has large amounts of real-world data from some of the variant outbreaks.
