A new CDC presentation from two days ago was mysteriously received by someone and is available to the public.
The presentation has a very important part called “VISION Multi-State Network of Electronic Health Records,” starting on Page 17.
This analysis is extremely important because it relies on a data set where patients have solidly documented vaccination status. This method of analyzing vaccine effectiveness does NOT depend on incorrect “estimates” of the percentage of unvaccinated people. Instead, the vaccination status of every individual is available via personal medical database records. In addition, the CDC scientists adjusted results by age and several other confounders.
The results are shocking. Here are the estimates of protection against HOSPITALIZATION from the original (monovalent) Covid vaccine. The extent of protection is called “vaccine effectiveness” and is abbreviated as VE.
For example, “protection against emergency visits” for 18-64-year-olds, given by the monovalent vaccine, was a measly 2 percent! Protection against COVID hospitalization for the same age group was only 19 percent!
Does this sound like a great deal of “severe illness protection”? It does not seem like it to me.
Maybe the bivalent booster, much touted by the CDC, would greatly help? The next slide dispels this notion. It shows “relative vaccine effectiveness (RVE).” Relative VE measures how much the bivalent booster helps, comparing monovalent-vaccinated people to bivalent-vaccinated people.
You can see that compared to those who declined the bivalent booster, people two months after having a bivalent booster would have hospitalizations reduced by only 31%.
This 31% is worse than it may seem: the bivalent boosted individuals are vaccine enthusiasts and are more likely to have had more previous doses than those who rejected the bivalents. Despite all these multiple doses, the chances of these enthusiasts being hospitalized for COVID are only reduced by 31% if we are to believe the CDC.
Not much.
