The “traditional” alternative
An analysis of more than 1,000 research articles concluded that few health problems are caused by or clearly associated with vaccines. A committee of experts convened by the Institute of Medicine to review the scientific literature on possible adverse effects of vaccines found convincing evidence of 14 health outcomes — including seizures, inflammation of the brain, and fainting — that can be caused by certain vaccines, although these outcomes occur rarely. It also found indicative though less clear data on associations between specific vaccines and four other effects, such as allergic reactions and temporary joint pain. In addition, the evidence shows there are no links between immunization and some serious conditions that have raised concerns, including Type 1 diabetes and autism…
The majority of these problems have occurred in individuals with immunodeficiencies, which increase individuals’ susceptibility to the live viruses used in MMR and varicella. Six vaccines — MMR, varicella, influenza, hepatitis B, meningococcal, and the tetanus-containing vaccines — can trigger anaphylaxis, an allergic reaction that appears shortly after injection. And, in general, the injection of vaccines can trigger fainting and inflammation of the shoulder, the committee noted.
The evidence suggests that certain vaccines can lead to four other adverse effects, although the data on these links are not as convincing, the report says. The MMR vaccine appears to trigger short-term joint pain in some women and children. Some people can experience anaphylaxis after receiving the HPV vaccine…
The committee’s review also concluded that certain vaccines are not linked to four specific conditions. The MMR vaccine and diphtheria-tetanus-acellular pertussis (DTaP) do not cause Type 1 diabetes, and the MMR vaccine does not cause autism, according to the results of several studies. The evidence shows that the flu shot does not cause Bell’s palsy or exacerbate asthma. Suggestions that vaccines can lead to these serious health problems have contributed to parental concerns about immunization for their children.
Establishing a cause-and-effect relationship between an agent and a health outcome requires solid evidence. The committee’s conclusions are based on the strengths and weaknesses of several types of evidence, including biological, clinical, and epidemiological research. In many cases of suggested vaccine-related adverse outcomes, there is too little evidence, or the available evidence offers conflicting results or is otherwise inadequate to draw conclusions…
Which won’t mean much to those suffering from the most notable American disease – irrational, spooky conspiracy theories relying on gossip for decision-making.
Computational analysis comes to the aid of modern medicine once again. I know it won’t touch the fears of the conspiracy crowd – but, it’s a delight to have a sufficient level of readily-available computing horsepower at hand nowadays to throw at a task like this one.
