About 0.01 percent of people became infected with COVID-19 between January and April despite being fully vaccinated, a US government study confirming the shots' high efficacy showed Tuesday.
"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.A total of 10,262 infections were documented at 14 days or more after the final dose of a vaccine provisionally authorized by the Food and Drug Administration -- Pfizer, Moderna or Johnson & Johnson.
The genomic sequences were available for five percent of all infections, and showed that 64 percent of cases came from variants of concern. 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.
