(CNN)There's good news about coronavirus vaccines. At least three of the experimental vaccines show remarkable efficacy, at least according to information released by the makers in news releases.
Global vaccine giant AstraZeneca reports its vaccine prevented coronavirus infection 62% of the time when people got two doses a month apart. But in a subgroup of volunteers who got a half dose followed by a full dose a month later, the vaccine appeared to be 90% effective.
That averages out to 70% efficacy. The vaccines made by Pfizer Inc and biotechnology company Moderna appear to protect against symptomatic infection 95% of the time.
