Experts Say Both Doses of Vaccine Necessary to Protect Against Delta Variant
With vaccine interest dwindling in the U.S., the COVID-19 Delta variant is becoming a major concern.
Early data suggests the variant, first discovered in India, is more contagious and deadlier than any other known variant.
Health experts are stressing the importance of getting vaccinated as cases of the Delta variant are on the rise.
A British study illustrates just how important it is to get both doses of the vaccine.
The Pfizer vaccine was found to be almost 90% effective against the Delta variant with two shots, but only 33% effective with just one.
