When can the US expect coronavirus vaccine rollout to start?
Fox News medical contributor Dr. Marc Siegel discusses upcoming COVID-19 vaccine distribution.
AstraZeneca and Oxford said Monday their vaccine was as much as 90% effective in preventing COVID-19, marking the latest candidate to inch closer toward approval. In a press release posted early Monday, the companies said there were no hospitalizations or severe cases of disease in trial participants who received the vaccine.
In the trial, the one-dosing regimen of AZD1222 got promising results when it was split into two jabs dated one month apart. The efficacy went from 90% down to 62% when two full doses were given one month apart.
“An Independent Data Safety Monitoring Board determined that the analysis met its primary endpoint showing protection from COVID-19 occurring 14 days or more after receiving two doses of the vaccine,” the firms said in the press release. “No serious safety events related to the vaccine have been confirmed AZD1222 was well tolerated across both dosing regimens.”
