The Centers for Disease Control and Prevention provided its first public data regarding breakthrough Covid-19 cases in the U.S. to CNN last week and it shows that vaccines are highly effective at preventing infections, hospitalizations and death.

Out of the 78.5 million people fully protected, the number of breakthrough cases only amounts to 0.0074%.
