While the coronavirus pandemic started with no vaccine, now several have been developed and are being administered, and in addition, the virus continues to be studied.  

Dallas County Health Department Public Information Officer Ann Cochran says even as more vaccines are administered, the virus will continue to be studied even after the pandemic has subsided. 

“The scientists who specialize in the study of infectious diseases will keep watch on the coronavirus worldwide even after it clears the U.S. For probably a decade or more studies will continue to figure out what we did early on that helped or hurt the efforts to keep people from dying from this disease.”

Cochran tells Raccoon Valley Radio one example of this is with the Johnson and Johnson vaccine and the rare blood clots that developed, along with the other adverse reactions. Cochran says the investigation showed the risk was extremely low for blood clots which is why Johnson and Johnson has started being used again.
