Protease inhibitors are currently used to treat such afflictions as HIV and hepatitis C.

If clinical trials go as planned and the Food and Drug Administration approves it, the drug could be distributed across the U.S. by the end of the year, Bourla told CNBC.

Health experts say the drug, taken orally, could be a game-changer because people newly infected with the virus could use it without needing to enter hospitals.

In addition to the drug, Pfizer is still testing its vaccine in 6-month to 11-year-old children. Vaccinating children is crucial to ending the coronavirus pandemic, public health officials and infectious disease experts say helping the country to reach herd immunity.

Earlier this month, the company asked the FDA to expand its vaccine authorization to adolescents ages 12 to 15 after the shot was found to be 100% effective in a study.

Bourla in the CNBC interview expresses optimism that the FDA will approve the use of the shot in adolescents.
