AstraZeneca said Dec. 11 that it will begin a clinical trial of its COVID-19 vaccine in combination with Russia's COVID-19 vaccine before the end of the year.
The trial will enroll volunteers 18 years and older.
Preliminary results have shown Russia's Sputnik V vaccine to be 90 percent effective in preventing COVID-19 infection, according to The Hill. Russia authorized the vaccine in August, the first country to do so. It began vaccinating people this week.
