So the poor people WOULD improve their chances of advancing by killing rich people.

Nonsense. It shouldn't be hard to grasp that a second hand off handed comment from someone who might or might not have a clue what's going on isn't something to take as a certainty.

Can you tell me what factor in the current atmospheric condition caused it to rain?

We know there's TB, where it is coming from is the open question here.

For the same reason chicken pox itself is increasingly dangerous as you get older, so is the vaccine.

Fortunately, I got my immunity the old fashioned way. No need for a booster.

You seem deeply invested in treating an offhanded remark you are reading second hand as the gospel. Any reason?

Why are you assuming he has personal experience in the three areas I mentioned? That would be a bit unusual. Actually, I guessed (but didn't assume) that he probably works at a regular paid practice as well.

Mostly, I am guessing that it was an off-hand comment rather than a careful statistical study.

Likewise, I am cautioning not to put too much stock in what was an off-hand comment made by someone who may or may not have any particular qualifications but almost certainly was not making a formal statement as an expert.

Many epidemiologists are physicians, but few practice.

Looking at the other post, immigration is corelated with TB but I see nothing that claims that to be at all causal. At most, we can say that one or more of those factors probably has something to do with it (possibly one step removed).

You may be surprised to know that many police departments break the law on a regular basis and then cover it up. Very occasionally they get caught. Still less often, something is done about it. It isn't hard for them to get away with it since mostly, the people with the authority to do anything about it would rather not know.

It doesn't matter if it's legal or not. Many will do it anyway. Then they will invent a (barely) plausible legal way they 'just happened to stumble over the evidence'. It is documented to happen.

It's common enough that it's worth considering what EM may radiate from your house.

Vaccines for children is a great idea. Adults don't qualify. The CDC price if for the actual vaccine in bulk, but it costs a surprising amount to get someone to sell you a dose and shoot it into your arm. They won't let you self-administer.

Experience at a free clinic would be suggestive of issues faced by the poor and lower middle class in general. To really draw conclusions from experience, he would need to have worked in a free clinic far from immigrant populations and in a clinic (free or not) in a wealthy area.

Did you read your link? It associated TB with poverty and a high minority population ( not independent factors). If you're going to scold, make sure your ducks are in a row first. Also note that what I questioned was the liklihood that the doctor was making an authoritative statement given the context.

Nah, they're just as pissy, they just have smaller bladders.

It is a lot more nuanced than that. There are vaccinations that work quite well. Rabies, tetanus, smallpox, and polio are examples. Flu vaccines do not work well due to our inability to predict which flu will be prevalent in a given year with accuracy (in other words, we keep vaccinating for the wrong thing).

Some such as chicken pox are questionable. They work for a time, but there is a real risk that over a lifetime, the risks are higher with it than without since the disease is a lot worse if contracted as an adult, but when contracted a a child it isn't a big deal.

Perhaps they can't afford it? Immunizations used to be dirt cheap but these days, not so much.
