As the COVID-19 vaccine roll-out continues worldwide to prevent the virus from spreading, an Illinois doctor says there is still a slim chance a person can get COVID-19 despite being vaccinated.

Statistically speaking, people have around a 5% chance of getting COVID-19 after being vaccinated, according to OSF General Surgeon Dr. John Wieland of Bloomington.

Weiland says the Johnson and Johnson COVID-19 vaccine, which has yet to be approved in the United States, has more "game-changing" messenger RNA technology than the Pfizer and Moderna vaccines.

According to Bloomberg, more than 26 million doses of the COVID vaccine in 43 countries have been administered.
