Your first link, as it has to do with vaccines, relates mainly to a minority view that is skeptical that flu vaccine reduces deaths* in the elderly. Apparently the article was published before it became widely known that H1N1 was disproportionately causing serious illness and death in previously healthy young people with strong immune systems. The article also contains the following:
"Nancy Cox, the CDC’s influenza division chief, says flatly, “The flu vaccine is the best way to protect against flu.” Anthony Fauci, a physician and the director of the National Institute of Allergy and Infectious Diseases at the NIH, where much of the basic science of flu vaccine has been worked out, says, “I have no doubt that it is effective in conferring some degree of protection. To say otherwise is a minority view.”
If you buy into the minority view, there remain other issues, such as that of herd immunity through vaccination protecting typically vulnerable people (children, the elderly and immunosuppressed). And even among vaccine skeptics there appear to be very few who’d want to do large scale double-blind placebo-controlled trials of flu vaccine, leaving half of participants unprotected against influenza,
Other parts of the linked article just seem silly - like the implication that getting vaccinated means people think they’re invulnerable and don’t take other precautions against getting sick. These measures (like handwashing, getting adequate rest and nutrition) are continually emphasized by physicians, so it’s not as if people are told to just get their shots and not worry. And the author is really stretching by including a reference to the Sinclair Lewis novel “Arrowsmith” as evidence of harm caused by premature reliance on a vaccine. (As a fan of this novel, I note that the article’s author is confused about a major plot line in the book - the anti-plague measure that the hero is researching is not a vaccine at all, but a bacteriophage (a viral “predator” on bacilli) that people were supposed to be injected with as a plague stopper.
The other linked article is a general blast at the fallibility of research studies, particularly single studies that proclaim statistical significance but don’t get replicated and confirmed in subsequent work. The problem with extending these conclusions to influenza vaccine is that there’s a lot of published research demonstrating vaccine efficacy, not just a random study here and there. (I’m also amused by the occasional research article that says we shouldn’t trust research. Presumably that includes all research, including that of the skeptic(s)). :dubious:
Here’s another study relating to vaccine effectiveness in the elderly.
“Conclusions
During 10 seasons, influenza vaccination was associated with significant reductions in the risk of hospitalization for pneumonia or influenza and in the risk of death among community-dwelling elderly persons. Vaccine delivery to this high-priority group should be improved.”
*it is very common among vaccine doubters and outright antivaxers to place emphasis only on deaths caused by vaccine-preventable infectious disease (statistics about which they’re typically wrong), and to ignore suffering, disability and permanent injury caused by these diseases.
