Third coronavirus vaccine succeeds at trials

AstraZeneca on Monday said its COVID-19 vaccine was up to 90 percent effective in late-stage trials. The manufacturing company and Oxford University ran trials of the vaccine in Brazil and the United Kingdom. Pfizer and Moderna also reported nearly 95 percent efficacy last week from similar late-stage trials.

What do we know about the vaccine? The vaccine uses a weakened version of a common cold virus combined with the genetic material for the protein of the virus that causes COVID-19. A half-dose of the jab followed by a full dose one month later proved 90 percent, while two full doses one month apart was 62 percent effective. Unlike the two other vaccines at late-stage trials, the Oxford-AstraZeneca vaccine does not require ultra-cold temperature for storage, making it easier to distribute in developing countries. Patients receiving the vaccine did not report any severe cases or hospitalizations. Regulators must approve the vaccine to allow for a widespread rollout.

    This appears to be great news -- three vaccines that are basically ready, that have 90%+ effectiveness, when experts were hoping for at least 60% effective. Thank the Lord!

    Does this one use aborted fetal tissue? 
    Are the vaccines good for one time, or does everyone have to get a new one each year? 
    Will they be required?
