Brazil's Bolsonaro asks Pfizer to speed up COVID vaccine delivery

Brazilian President Jair Bolsonaro on Monday asked Pfizer to bring forward planned delivery of COVID-19 vaccines, a government source said, aiming to speed up a slow national inoculation program. The request is a turnaround for Bolsonaro who last year ignored offers of vaccines from Pfizer, according to testimony to a Senate commission investigating delays in vaccinating the country with the world's second-deadliest outbreak.
