odyssey7•13h ago
Vaccines are unpopular with many. I don’t see why the motives have to be more complicated than that.

But, I would say that trying a different approach that acknowledges how patients feel could help rebuild public trust in healthcare institutions. Taking a broader viewpoint, this could save lives.

Vaccines eradicated some of the worst diseases humans had. If thousands of kids were paralyzed by polio vaccines would become very popular again.

I think the idea that changing stated recommendations based on the public opinion is a questionable strategy that can just backfire into more distrust and behavior that follows the "true" best practices even less as they look for the 'sensible position between extremes'[1].

There are a lot of examples from the response to COVID: frequent early mixed messages around the effectiveness of masks for preventing infection and transmission not based on the actual understanding of said effectiveness but in order to manage supply shortages, arguable overstatement about the one-time long-term effectiveness of the initial vaccines against infection and transmission and not just severity of disease, overemphasis on ineffective measures like hand hygiene or six-foot-distancing over effective measures like air cleaning and masking based on the perceived willingness of the public to follow them, reduction of the stated duration of contagiousness without evidence of such.

It's one thing if it's genuinely not known what the best practices are, but knowing and misleading can confuse people who are willing to follow them and can further alienate skeptics who may seek out charlatans promising them the "real, unfiltered truth".

odyssey7•6h ago
Expert opinions are pluralistic, not a monolith, so there’s a judgement call when a policy is written. There is a spectrum of importance when you consider medical interventions. A pluralistic society, including pluralistic opinions among experts, is the norm outside of 1984. It’s just reality.

Policymakers could prioritize more or fewer vaccines, and the reasons to prioritize any particular vaccine would be expected to change over the decades.

Why the CDC isn’t prioritizing more vaccines might be seen as reckless to some. I think it’s a huge mistake that there isn’t a strep vaccine and a universal mandate for that, but it’s clearly not been historically prioritized. Strep has been known for decades to cause mental health conditions in children.

On the other hand, some infections might be better handled by vaccinating around where cases show up, a capability that is possible only now that we have electronic medical records, better tests, the information era, etc. Just-in-time logistics is a huge success story of the modern world.

Opinions of experts are important: expertise requires that opinions should change as the realities do.

An expertise that’s required of a policymaker is to maintain the effectiveness of their institutions by translating expertise into policies that are actually listened to. We have serious warning signs that public trust in healthcare is disintegrating, and that the vaccination campaigns are failing. Policies that are more focused could play out better.

Infants have rights too. It's against the law for a "seatbelt skeptic" not to put their kid in a safety seat.
odyssey7•7h ago
As you increasingly mandate things that the public thinks are optional, eventually mandates in general start to look unimportant, and eventually you get less safety seat compliance.

If there are some illnesses we can handle with without universal vaccination, then including those vaccines as mandates means you’ll eventually get less compliance for high-priority vaccines too. This is what we’ve seen play out when the public distrusts medical authorities. We live in a democratic society and (not) listening goes both ways.

psyklic•1h ago
How many deaths are acceptable to say we can "handle" an illness?

Public health requires over 95% vaccination. There has never been a realistic path to that other than requiring students to be vaccinated to attend school. Without that requirement, even well meaning parents forget or may not make it a priority.

It's not fair for kids and others vulnerable in society to die because certain parents are ignorant.

Common Kennedy is THE person that worked very actively and hard to turn people against vaccines.

He wanted to make them unpopular, partially succeeded and now is trying to remove them.

ndsipa_pomu•10h ago
Maybe we should bring back leeches if we're just going to ignore medical science and instead just go with the feelings of a misinformed public.
odyssey7•6h ago
Do you want public advice that is followed (useful) or public advice that is ignored (not useful)?

The ability to have the public accept advice is a capability that has unquestionably eroded. However smart an expert may be, they aren’t helping anyone if people won’t listen when they speak.

ndsipa_pomu•5h ago
Public advice should be as complete and accurate as possible. If there's a recommendation that is unlikely to be followed, then that can be indicated along with the alternate next best suggestion. e.g. "COVID prevention is best with a complete Hazmat suit, but just a mask may provide some benefit"

The job of experts is mainly to provide information and the job of the public is to pay attention to relevant information. If the public decides to ignore advice (e.g. "no level of alcohol consumption is safe"), then that doesn't change what the advice should be.

odyssey7•5h ago
I appreciate the nuance you’re bringing to this topic.

The child vaccinations schedule is a step further than public advice due to its role in clinical practice and social expectation setting. Policymakers have a job that stands apart from that of both the medical experts and the general public, and the child vaccinations schedule is a policy document, not simply a medical one.

aussieguy1234•14h ago
In many developing countries folks don't get vaccinated either and a lot of them die. TB, Typhoid, Hepatitis and others are still major problems.

So with this approach, the US will be going the way of those developing countries.

Apart from the deaths, there will almost certainly be economic damage.

nwienert•14h ago
Like Japan or Denmark, which closely align to the new schedule?

Without the postpartum and early childcare of those countries.

Denmark doesn't do mandatory vaccines to the same degree as they catch early development of disease and treat it when it appears, consistently across the whole population.

The US has a case for mandatory multi childhood vacination as the data shows otherwise preventable childhood diseases will spread untreated and unchecked.

If you like Japan and Denmark and want the same - get onto improving the US health system for everybody regardless of employment status.

lostlogin•11h ago
Imagining isn’t the way to do this. There is hard data on the harm vaccines cause and the benefit provided. That’s the point of the scientific organisations US taxes fund.

Abandoning a scientific approach and using whatever this administration is doing is what was voted for I guess.

joshcsimmons•8h ago
This is directionally correct but methodologically flawed.

The US requires 5-10 more vaccines for children by 5 years old than Japan does. Japan also has a much more spaced out schedule over those 5 years.

Given that the American health machine is largely driven by pharmaceutical companies, it seems likely that there is some fat that can be trimmed. Did they trim it here? Who knows.

hshdhdhj4444•7h ago
Japan has a different medical system, different levels of adherence, different cultural hygiene standards, different exposure risk profiles for different pathogens.

Comparing the U.S. to Japan, or any other system for that matter, with a simple “well the vaccine schedule is different there” is simplistic and almost certainly not useful.

What is useful is to compare the U.S. with and without a certain vaccine or when delaying certain vaccines.

And we know how that plays out because all these vaccines have been added because of specific threats and actual diseases faced by Americans.

jimmydddd•6h ago
Not sure "comparing A to B is 100% totally useless because A and B have some differences" is a good strategy?
