@tracy_tysonmd: Replying to @Caffeine&Chaos “Why haven’t they injected different doses of formaldehyde into babies just to see what happens?” Because that would be unethical, unnecessary, and scientifically impractical. Toxicology doesn’t require deliberately exposing infants to potentially harmful doses of a substance. Instead, scientists can study how a substance is produced, metabolized, cleared, and distributed in the body and use pharmacokinetic modeling to estimate exposure. That’s exactly what researchers did in a 2013 vaccine study: they modeled infant exposure to formaldehyde from vaccines and compared it with the formaldehyde infants naturally produce and already have circulating in their bodies. Good science isn’t defined by doing the most extreme experiment imaginable. It’s defined by using the best study design to answer the question safely and accurately. Not having an unethical experiment ≠ not having safety data. #Vaccines #VaccineSafety #Formaldehyde #Pediatrics #Toxicology
Who on earth would volunteer their child for a study knowing they’re TRYING to poison them 🤷♀️🤦♀️I can’t even anymore 🙄

They learned that placebo controlled double blinded studies are the gold standard and inferred that this is the *only* way for science to advance. Obviously this is extremely flawed, all-or-nothing thinking.

These are also the people who think the only real placebo is saline.

I beg people to learn about good clinical practice and ethics and research. As someone who works in clinical research, I’m dying out here!

So many of the people in our communities are uneducated and taught to fear knowledge. It is a failure on the part of our leadership and the people that allowed them to lead.

It’s similar to like how we don’t know how much etoh is safe do consume during pregnancy bc why would we ever test it?

people don't realize how much we know in medicine is from the terrible things done during WW2 and other wars. like the information is valuable but the only way to get that information is inhumane so of coarse we don't study it.

We also KNOW the whole vaccine, as packaged and formulated, is safe, effective, and performs at least as well as previous versions. Statistics doesn't parse out the antigen effect from the adjuvants, preservatives, saline, or even the needle prick itself. But if he wants a study, he's more than welcome to fund it.

These anti-VAX idiots have absolutely no idea what ethics actually is in clinical trials. I say this as someone who runs oncology clinical trials for a living.

the irony of them wanting babies to be given study doses to prove they shouldn't be given any doses😂

I know you're using a collective we in the sense of "humanity" and "the healthcare and health science community" but I honestly think a lot of the disconnect is that "we All" decidedly did NOT know that the body naturally makes and processes formaldehyde. Or that when you see a brain floating in a jar THATS NOT EVEN FORMALDEHYDE EITHER😂
