South Africa announced Thursday that it will import 1.5 million doses of a COVID-19 vaccine developed by England's University of Oxford and British-Swedish pharmaceutical giant AstraZeneca.
South African Health Minister Dr. Zwelini Mkhize said the country will be receiving 1 million doses later this month, followed by 500,000 doses in February. Mkhize said the healthy ministry has purchased the doses directly from the Serum Institute of India, which has a licensing agreement with AstraZeneca to manufacture the vaccine.
Meanwhile, South Africa's drug regulatory body is "fine-tuning and aligning all the regulations processes to ensure that there are no unnecessary delays or regulatory impediments to activate this rollout," Mkhize said.
The country's health care workers in both public and private hospitals -- an estimated 1.25 million people -- will have first priority in getting the vaccine, according to Mkhize.
The announcement comes as South Africa grapples with a new, more contagious variant of the novel coronavirus. Some hospitals are reportedly already at capacity amid the recent surge in infections.
South Africa has reported more than 1.1 million confirmed cases of COVID-19 since the start of the pandemic, including at least 30,524 deaths, according to the latest data from the Africa Centers for Disease Control and Prevention. The country of 60 million people has by far the highest number of diagnosed infections in Africa.
Los Angeles County reported 258 new deaths and 11,841 new cases on Wednesday.
County Public Health Director Dr. Barbara Ferrer said Wednesday, “Today, I am more troubled than ever before.”
During the summer, 1 in every 10 people tested were positive; now, 1 in every 4 or 5 people are testing positive, she said.
The rate of transmission this month is almost double that of December and Los Angeles County hospitals are admitting more patients than they can discharge, she said.
Some paramedics told ABC News they’ve seen as many as 22 ambulances stacked up in hospital parking lots this week. They said they felt helpless waiting.
“They signed up to take care of people, not wait with people in agony,” EMT Bill Weston told ABC News.
“This is by far the worst disaster I've ever been involved in,” he said.
