(I have a workshop long stocked with both disposable surgical and N95 masks and reusable P100 masks/cartridges, so I have no skin in the game.)
I don't think their credibility should be negatively impacted for updating their advice with the latest science. It's a shame people are reading it in the most negative light possible.
As a scientist, my answer to “should we wear masks?” wouldn’t have been to deflect to contaminated surfaces - even setting aside that subsequent research showed that to be largely a non-issue.
But now that masks are common place, the guidelines were evolved to reflect the new reality.
Clearly vitamins are better than a drug that has been in use for decades with a proven safety record AND while being recommended by physicians bound to the hippocratic oath.
Why can't there be validity to both vitamins and certain existing drugs? (AND vs OR)
It as though we actively do not want to admit that we may already have something out there that can help us.
PS: Vitamins is a friendly name for often synthetic or derived compounds, not necessarily in the exact same chemical structure as found naturally in organic matter. Not to mention there are also various chemistries that affect absorption etc.
Vitamin C and D are over the counter, or easily obtained from diet (citrus fruits and milk).
Moreover, HCQ was promoted by political entities as “100% effective” for COVID-19 (viral Charlie Kirk tweet, quoted by Rudy Giuliani, deleted by twitter). There was no clear scientific evidence of this and it was studied extensively and the best scientific trials (RCTs) of HCQ have shown no effect on the disease progression.
A big part of the concern with HCQ is that it was promoted as a cure alongside the claim that all other efforts to fight the virus could be discontinued, since HCQ would cure the disease.
HCQ is a drug that most people will never consume, can have adverse effects and cause allergic reactions, and was often recommended at doses more likely to cause side effects. Taking it is better than having malaria, but taking it without a proven benefit is a dangerous choice.
* it still has had no good RCTs backing it up
* it has significant negative side effects
But I have been eating zinc and quercetin rich foods, like spinach and kale (respectively). Quercetin is a zinc ionophore like HCQ but without the side effects.
I don't understand what your problem with vitamin C and D supplements is. People have taken supplements for a long time, and those vitamins have been a part of the human diet for much longer than HCQ has existed.
I also find it amusing that I get down voted on HN whenever I bring it up. Sheep.
Plus, your theory doesn't have any legs because it makes no sense for other countries to ruin their economies and lockdown themselves just to make Trump look bad. If it was a magic cure then countries like India wouldn't give a flying fuck about Trump or whatever your pet theory is.
It does seem to be a valid treatment option and most countries that temporarily stopped using it soon reinstated it as their mortality rates spiked.
