OXFORD, United Kingdom. — AstraZeneca says its COVID-19 vaccine is highly effective in preventing the disease.
The drug company and the University of Oxford are in late-stage trials of developing a coronavirus vaccine.  Today, researchers are claiming the new vaccine prevented 70-percent of people from developing the virus.
The head researcher said those who were given a half dose followed by a full dose were about 90-percent protected.  He said the test shows that it’s an effective vaccine that will save many lives.
Last week, drugmakers Pfizer and Moderna reported preliminary results showing their COVID-19 vaccines were about 95-percent effective.
