This is my concern for undocumented immigrants.
...I'd be interested in knowing your source of information...
My eyes, ears, and heart provide the sources of concern for outbreaks among undocumented individuals. It is interpersonal. I did not need statistical data to have human empathy and concern. Local PSAs on TV may have been of some influence in raising my awareness.
We also have things like DTaP as an alternative to DTP (a vaccine which resulted in some claims).
No, we don't. DTP isn't an alternative to DTaP; it's an old vaccine for the same diseases (licensed 1949). It hasn't been used in the United States since 1991. The risk of neurological problems due to the old vaccine was 1:140,000 ---
I did not mention DTP as an alternative for DTaP. Rather I stated DTaP is the alternative. You reversed it in your post. To expound upon my original sentence, in the event clarity may be needed: We now have an alternative between DTP and no vaccine: it is DTaP. We agree that DTP resulted in some claims. While you posted that DTP was not administered since 1991, I have different information indicating DTaP was administered only on request and DTP continued to be administered as the default.
you're doing a great job of demonstrating how people argue/make decisions based on misinformation. This is bordering on being enough for a case study.
I have acknowledged concern for people in their suffering... including vaccine-claimant families, undocumented immigrants upon being ill. There is no misinformation, decision, or argument in my posts. I have tried to convey an open-minded respect for individuals' varied experiences.
In summary, the OP's linked articles suggested higher IQ correlated with better health, possibly with a patient's independent personal research and advocacy having a causal relationship or being one determining factor. Meanwhile several posters have cited cases where they believe higher education may lead to more risk-taking... whether through hubris/arrogance, plethora of material of questionable value which people may encounter when researching, or relying more on personal anecdotes than peer-reviewed published research.
Health/medicine is a fascinating field with new scientific and behavioral studies and observations ongoing. What research indicates one year may be set aside at a later date. Except for hand washing... that was proven to provide health benefits over a century ago... wikipedia link-
