Pfizer expects to cut COVID-19 vaccine production time by close to 50% as production ramps up, efficiencies increase

Pfizer expects to nearly cut in half the amount of time it takes to produce a batch of COVID-19 vaccine, from 110 days to an average of 60, as it makes the process more efficient and production is built out, the company told USA TODAY. As the nation revs up its vaccination programs, the increase could help relieve bottlenecks caused by vaccine shortages.
