Vaccinated Americans have been getting their second doses on time, CDC says.
A new CDC analysis reveals that nearly 9 in 10 Americans who received the first dose of a two-dose COVID-19 vaccine have completed the regimen, and the majority of people who received two doses did so within the recommended time frames. The analyses comprised data on 40.5 million Americans who received the Moderna or Pfizer-BioNTech vaccines between December 14, 2020, and February 14, 2021. In one analysis, CDC researchers examined the records of 12.4 million people who received the first dose of a two-dose vaccine regimen and had enough time to receive the second dose. Roughly 88% completed the series, while 8.6% were still within the allowable interval — 42 days — to receive the 2nd dose. About 3.4% missed that window. The percentage of people completing the regimens varied considerably by jurisdiction and between demographic groups. Among vaccine recipients for whom information on race and ethnicity were known, the lowest completion rates were among Native American or Alaska Native individuals. A second analysis of 14.2 million people who completed the full regimen found that 95.6% received the second dose within the recommended period, with figures varying widely by community. The study authors urged providers and public health workers to encourage Americans to return for second doses; stress the need for full vaccination; and identify hurdles people face, such as access or lack of confidence in the vaccines.
