Masks with close to zero efficacy according to a systematic review of 78 studies by Cochrane:
🇳🇱
Because it is a systematic review by Cochrane that in this field usually mean "this is the state of the art at the moment".
Having studies pointing to the opposite is normal. I have read both those in favor of masks and those against and have drawn my conclusions.
Systematic reviews exist precisely to bring order. And this one, from the most renowned organization of evidence-based medicine, confirms my conclusions at 100%.
From now on, saying "there are also studies that say the opposite about masks" is ideological, rhetorical and anti-scientific.
✅ Scientific literature denies the effectiveness of lockdowns
✅ Scientific literature denies the effectiveness of masks
🕐 Scientific literature denies the effectiveness of Covid vaccines
It's a matter of time...

It doesn't say so.
