AstraZeneca coronavirus vaccine safe, 70% effective, study suggests
Experts say the vaccine seems likely to be approved
Operation Warp Speed chief adviser: Any hesitation from Americans about taking coronavirus vaccine is ‘concerning’
Dr. Moncef Slaoui, chief adviser to Operation Warp Speed, tells ‘America’s Newsroom’ that the U.S. is committed to immunizing the U.S. population by the end of 2021 and addresses public fears about the vaccinations.
New results on a possible COVID-19 vaccine from Oxford University and AstraZeneca suggest it is safe and about 70% effective, but questions remain about how well it may help protect those over 55 — a key concern for a vaccine that health officials hope to rely on around the world because of its low cost, availability and ease of use.
Still, experts say the vaccine seems likely to be approved, despite some confusion in the results and lower levels of protection than what other vaccine candidates have shown.
“What we can see looks reasonable, but it’s a bit more complicated than what we’ve seen so far,” said Dr. Buddy Creech, a Vanderbilt University researcher helping to test two other vaccines. “If this had been the first report out, the field would have still been excited to have a vaccine.”
The medical journal Lancet on Tuesday published partial results from tests of the vaccine in the United Kingdom, Brazil and South Africa — safety results on 23,745 participants and protection levels on 11,636.
