LONDON (AP) — AstraZeneca said Monday that late-stage trials showed its coronavirus vaccine was up to 90% effective, giving public health officials hope they may soon have access to a vaccine that is cheaper and easier to distribute than some of its rivals.
The results are based on interim analysis of trials in the U.K. and Brazil of a vaccine developed by Oxford University and manufactured by AstraZeneca. No hospitalizations or severe cases of COVID-19 were reported in those receiving the vaccine.
AstraZeneca is the third major drug company to report late-stage results for a potential COVID-19 vaccine as the world anxiously waits for scientific breakthroughs that will bring an end to a pandemic that has wrought economic devastation and resulted in nearly 1.4 million confirmed deaths.
Pfizer and Moderna last week reported preliminary results from late-stage trials showing their vaccines were almost 95% effective. But, unlike its rivals, the AstraZeneca vaccine doesn’t have to be stored at ultra-cold temperatures, making it easier to distribute, especially in developing countries.
“I think these are really exciting results,” Dr. Andrew Pollard, chief investigator for the trial, said during a news conference. “Because the vaccine can be stored at fridge temperatures, it can be distributed around the world using the normal immunization distribution system. And so our goal … to make sure that we have a vaccine that was accessible everywhere, I think we’ve actually managed to do that.”
