US Trial Shows AstraZeneca Vaccine Is Safe and Effective



AstraZeneca Vaccine Shown to Be 79% Effective

A US trial found that the COVID-19 vaccine developed by AstraZeneca (AZN) and Oxford University is safe and highly effective. The 32,449-person trial showed that the vaccine is 79% effective against symptomatic illness and 100% effective at preventing severe illness and hospitalization.

For context, the Moderna (MRNA) vaccine has proven to be 94% effective at preventing COVID-19. The Pfizer (PFE) and BioNTech (BNTX) vaccine has been shown to be 95% effective.

European Countries Restart Distribution After Safety Concerns

A number of countries paused use of the shot due to reports that some people had developed blood clots after receiving the vaccine. But the results of the US AstraZeneca trial were published yesterday, , and have shown that the shot is safe.

The World Health Organization and the International Society on Thrombosis and Hemostasis have recommended that governments resume distribution of the AstraZeneca vaccine. Countries including France, Italy, and Germany have started giving out the shot again.

Emergency Use Authorization in the US

Now that results of the trial are out, AstraZeneca plans to file for emergency use authorization of its vaccine in the US early next month. AstraZeneca says that if the FDA approves the shot, it will be ready to distribute 30 million doses in the US immediately.

COVID-19 vaccine rollout is progressing steadily in the US. Over 44 million people in the country are already fully vaccinated, which is about 13.3% of the US population. Soon, one more safe and effective vaccine candidate will likely be available.
