These keep coming out, and it is worth noting the trends of the research as well, now that the official story has kind of changed to “gee, that epidemic response really was stupid”.
This is actually a pretty important study, because it deals with methodological issues in the assessment of vaccine efficacy, or really the efficacy of any treatment. Qatar, which has a good health system, has done interesting CV-19 research. This study attempted to assess the presence of a “healthy vaccinee” bias in studies on vaccine efficacy. While some studies attempted to adjust for health status differences between those who were and weren’t vaccinated, the adjustment was rarely complete. Qatar’s own work on vaccine effectiveness in two large studies was examined. Despite attempts at cohort matching, all-cause mortality in succeeding months suggested a very large remaining bias toward healthier persons getting vaccinated, particularly in the population aged 50 and over.

And on the other side of efficacy studies we have safety ones, where the VSNs continue to misrepresent everything they can. Somehow this study on a new form of mRNA vaccine is said to say that adverse events were widespread. There were some, if you consider a slightly sore shoulder an adverse event. Here is what the authors actually said: “No serious vaccine-related events occurred.” (Vaccines Study)
As if the American public needed another excuse for malingering, CV-19 has been said to have many post-acute impacts, often referred to as “long” CV-19. Every serious disease tends to have lingering symptoms, so CV-19 should not be any different. This study looked at the extent to which their were differences in symptoms following a CV-19 versus influenza infection. The study was done in the Kaiser health system. There was no general greater risk of post-acute symptoms between the two infections, although those persons hospitalized with CV-19 had a somewhat higher risk of complications necessitating additional hospitalization, (Medrxiv Study)
Another study compared CV-19, influenza and RSV infections. CV-19 and influenza had similar rates of inpatient use, while RSV had far higher rates. Of the three, RSV clearly seems to be the most serious, leading to far heavier use of health system resources. Fortunately it also seems to have a lower prevalence. (Medrxiv Study)
Notwithstanding the plethora of research and real-world evidence indicating that they are pretty ineffective, people are still trying to justify additional vaccine doses. The primary authors are funded by pharmaceutical companies and are likely trying to justify their earlier failed predictions that vaccines would stop infections from spreading, In any event, this study looks at 2024-25 vaccine effectiveness and found that it was a pathetic 41% effective against hospitalization. You may recall that usually effectiveness against hospitalization is much higher than against infection, so I assume that it was worthless versus infection. As usual the attempt to match groups receiving and not receiving the vaccine is inadequate. (Medrxiv Study)
Young people generally had very mild CV-19 infections. Among those who did not, this study examined what characteristics might account for severity. Being African American and being obese were the most substantial risk factors for a CV-19 hospitalization among children and young adults. Asian Americans were least at risk. (Medrxiv Study)
The Qatar study on the vax effectiveness of the healthy vs non healthy is interesting. The higher death rates for the unvaxed may be partially explained by a larger percent of that unhealthy subpopulation not getting a vax, thus giving the appearance of the vax being more effective than actual. With any health study, proper accounting for other variables should be made to avoid erroneous conclusions. My observation is that hospitalization and death from covid are directly correlated to overall health of the individual, so without adjusting for pre covid health status, most of the vax effectiveness studies are flawed.
My personal observations -Several of my elderly clients/customers who were not very healthy did not get vaxed for what appears to have been a fear of getting exposed to other people (not because the feared the vax ). Thus the qatar study has some validity. I will note that I fall on the other end of the spectrum since I chose not to get vaxed because I judged my health risk from covid to be very low due to my better than average health status.
