COVID-19 cases among vaccinated seniors soared in 2021, according to newly disclosed data that was acquired by U.S. health agencies but not presented to the public.
Humetrix researchers found that the proportion of total COVID-19 cases among the seniors was increasingly comprised of vaccinated people, according to the newly disclosed documents.
For the week ending on July 31, 2021, post-vaccination COVID-19 cases represented 73 percent of the cases among people 65 and older, the company found.
The breakthrough cases started in January 2021, according to the data.
Humetrix also found that among the beneficiaries, there had been 133,000 cases, 27,000 hospitalizations, and 8,300 intensive care admissions among the fully vaccinated since the start of the COVID-19 pandemic.
During the meeting, CDC officials went over emerging data on waning vaccine effectiveness.
The CDC did present data from COVID-NET, one of its systems, that showed effectiveness against COVID-19-associated hospitalization was falling among the elderly since the emergence of the Delta variant but that data still showed 80 percent effectiveness.
