A report published by the Centers for Disease Control and Prevention (CDC) said that about 0.01% of people contract the coronavirus despite being fully vaccinated. This confirms the high efficacy of the vaccine.

The report, named as “breakthrough”, showed cases among 101 million people who are fully vaccinated in the United States.

“Even though FDA-authorized vaccines are highly effective, breakthrough cases are expected, especially before population immunity reaches sufficient levels to further decrease transmission,” the report said.

It examined the period from January 1 to April 30.

A total of 10,262 infections were documented at 14 days or more after the final dose of a vaccine.

Of these cases, 6,446 or 63% occurred in females.

Among the total number of breakthroughs, 2,725 or 27% were asymptomatic, 706 or 7% were hospitalised for COVID-related issues, and 1% died from reasons related to Covid.

The rate of breakthrough infections is thus roughly 0.001%, hospitalisations are 0.0007%, and deaths are 0.0001%.

The study occurred during a period when the coronavirus was surging through the United States, with approximately 355,000 cases reported in the last week of April alone.

“The number of Covid-19 cases, hospitalizations, and deaths that will be prevented among vaccinated persons will far exceed the number of vaccine breakthrough cases,” the authors wrote.

About 50% percent of the United States’ total population have now had at least one dose of vaccine.
