World News – AU – Study Confirms AstraZeneca’s COVID-19 Vaccine Is Moderately Effective


. .

Peer-reviewed research released Tuesday confirms that the coronavirus vaccine developed by AstraZeneca and Oxford University is moderately effective in preventing infection and it appears to keep people out of the hospital.

Why It Matters: Some questions about AstraZeneca’s vaccine remain, but the results published in The Lancet medical journal help confirm that the product works and is safe.

The big picture: When AstraZeneca’s vaccine was given in two standard doses, it was approximately 62% effective in preventing symptomatic infections.

The big question: the company inadvertently gave some patients a modified dosage regimen – half a dose followed by a standard full dose. In these patients the vaccine registered 90% effectiveness.

The lower starting dose also appeared to be much more effective in preventing asymptomatic spread – a critically important part of preventing the virus from spreading.
