Company executives and some public health officials have expressed hope that this recombinant protein-based vaccine will be more palatable to the vaccine-hesitant than existing vaccines using new (and therefore scarier) mRNA and adenovirus If we need additional booster shots in the future, it will be important for us to have an appropriate vaccine supply here in the U.S.. Moderna uses the same mRNA technology as Pfizer-BioNTech and had a similarly high efficacy at preventing symptomatic disease when the companies applied for authorization; it also needs to be stored in freezer-level temperatures.
