Not really, because if there are long-term side effects, we need to have a control group.
For example, the vaccine used for the 2009 Swine Flu:
https://en.wikipedia.org/wiki/Pandemrix https://en.wikipedia.org/wiki/Pandemrix
"Pandemrix was found to be associated with narcolepsy from observational studies, increasing the risk of narcolepsy by 5-14 times in children and 2-7 times in adults. The increased risk of narcolepsy due to vaccination in children and adolescents was around 1 incident per 18,400 doses."
If you don't have a large section of the population unvaccinated, you can't conclusively prove that the vaccine was the cause.

It’s just, which would you rather have: a perfectly run trial because your vaccine efficacy is so low that your control group doesn’t feel incentivized to get vaccinated? Or a vaccine that works well enough to quell a pandemic, causing your control group to jump ship and potentially lessen your statistical power?

- H8crilA 5y agoThere was a comment here that got deleted. It had something cool I haven't seen before: a risk calculator/estimator for Covid (both death and hospital admission), for the UK: https://qcovid.org/Calculation https://qcovid.org/Calculation
- chiefalchemist 5y agoInteresting. Especially that it uses a number of different "properties" (e.g., post code) to "fine tune" the calculation.
- guscost 5y agoEither way, the higher-order effects will continue and cascade in perpetuity. The world is not a well-controlled experiment, and if you think there is an obvious “better” choice here which can be separated from all the context, then you have no idea how the world works.
- hprotagonist 5y agoand if you think all choices are obviously bad (because there's no discernable 'better'), then i don't want you running a public health office. (disclaimer: i've run experiments with patients, i'm well aware of how messy the world is)
- guscost 5y ago> i'm well aware of how messy the world is No, you are not. Not even close.
- jdavis703 5y agoIn this case, there is a suspected autoimmune link between the similarity of the inactivated viral protein and a brain protein that is associated with sleep regulation. The real question to ask isn’t whether the placebo group was better off, but whether people infected with Swine Flu had a lower risk of narcolepsy than vaccine recipients.
- markus92 5y agoNot necessarily true. The incidence rates of those are well-known. Rarer side effects are impossible to find by comparing vaccinated/unvaccinated in a phase 3 and need larger groups to be found. That’s routine, though. Look at the VITT for the Adenoviral vector vaccines, no strict control group was necessary to identify that.
