The CDC has recorded second doses and booster shots as first shots, thereby largely exaggerating statistics, said the report.
While the CDC's data show around 240 million Americans had received at least one dose of a vaccine, only 203 million were fully vaccinated, suggesting 37 million U.S. citizens got one shot without completing their vaccination, it said.
This gap is highly unrealistic as it is far larger than other developed countries.
The European Union has just a 2.6 percent gap between the singly-vaccinated and the fully-jabbed, while the U.S. has the largest disparity at 11 percent, said the report, citing Bloomberg's statistics.
