Pfizer's Covid-19 vaccine should be delivered to local pharmacies in the U.S. within 3 weeks, said Gen. Gustave F. Perna, the chief operating officer for the government's Operation Warp Speed. Pfizer Inc. gained emergency U.S. authorization for its Covid-19 vaccine on Friday, completing an unprecedented scientific sprint that could eventually help bring an end to a pandemic that has killed nearly 300,000 Americans. The Food and Drug Administration’s decision to authorize use of Pfizer and partner BioNTech SE’s vaccine will now set in motion a complicated immunization drive that will launch across the country in coming days. Gen. Gustave F. Perna, the chief operating officer for the government vaccine program Operation Warp Speed, said at a news briefing Saturday that vaccines are being packaged and will arrive at the first administration sites on Monday. Among the first to be inoculated will be health-care workers and seniors living in long-term care facilities. The shot is a landmark achievement, built from a breakthrough technology in a matter of months, in the face of a pandemic that has sickened millions worldwide. It has already been cleared by regulators in the U.K., Canada and other countries.
