Roughly 221 million doses of the Pfizer-BioNTech vaccine have been dispensed thus far in the United States, compared with about 150 million doses of Moderna's vaccine. In a half-dozen studies published over the past few weeks, Moderna's vaccine appeared to be more protective over the long term than the Pfizer-BioNTech vaccine.
