> I heard that the flu vaccine is also around 30% effective. The flu vaccine is so ineffective that if we actually applied evidence-based medicine standards to it / actually looked at a real cost:benefit analysis, we would never be pushing the flu vaccine. https://www.cochrane.org/CD001269/ARI_vaccines-prevent-influenza-healthy-adults https://www.cochrane.org/CD001269/ARI_vaccines-prevent-influ... > Injected influenza vaccines probably have a small protective effect against influenza and ILI (moderate-certainty evidence), as 71 people would need to be vaccinated to avoid one influenza case, and 29 would need to be vaccinated to avoid one case of ILI. Vaccination may have little or no appreciable effect on hospitalisations (low-certainty evidence) or number of working days lost. So: a miniscule reduction in actual flu cases (granted, a slightly-better-but-still-weak reduction in general ILI), with no appreciable difference on hospitalizations or working days lost, meaning that the economic benefit of giving the flu vaccine is basically zero. It's pretty great that the first world (at least America) has been so heavily socialized to accept the flu vaccine as effective and necessary, because it makes arguing for the effectiveness of the COVID vaccine much easier, since the bar is so incredibly low.
