The CDC has indicated on their website for months that 92% of adults have taken at least on shot of a COVID-19 vaccine. Yet a prior surveys Zogby and Rasmussen indicated that fraction may only be two thirds.
Now a recent, independent report from Northeastern University has found that the proportion of unvaccinated is not 8% but more like 25%. This agrees separately with a Kaiser Family Foundation report. Apparently the CDC vaccination administration system is not accurately identifying each person by a unique identifier and linking each injection to that code. Therefore, if a patient does not have the prior vaccine card or goes to a different vaccines center with slightly different name spelling, then the encounter is counted as a brand new person coming forward. This is leading to double-counting of “vaccinated” in CDC records.link
