An article from 2012... That's super relevant. And then at the bottom page, the author brings up the "poison" ingredients.
It's like you don't even try. And the fact you continue to play your "bUt ThE fLu" card in this thread is an excellent display of abject ignorance. Yes, the flu is bad. It does its share of damage every single year. WTF does that have to do with COVID-19, though - a completely different and new virus?
There's also no valid argument against getting the flu shot if you're healthy and able to get it. Obviously, there are exceptions who can't get it but that's the importance of herd immunity. The flu shot has proven to work and if more people bothered to get it, instead of listen to idiots who spread misinformation and lies fueled by ignorance and willingness to learn, there would likely be far fewer deaths from influenza every year. Outside of mandatory vaccination, what measures would you like to see against the various flu strains that circle the glove every year? The simple reality is people need to do their part, but many do not - and choose wilfully to do so.
The difference with COVID-19, a novel* coronavirus, is there is no vaccine or other measures available to stop or lessen its lethality. That's why it's been so damaging since it spread globally: we don't have the means to fight it the same way we do other viruses. That's why the experts (doctors, epidemiologists, virologists, etc.) have told us to stay home, distance from others, and avoid travel to minimize that damage and not overwhelm medical infrastructure while slowing the spread. Again, though: people need to do their part and listen.
* novel means new, as in it is a new strain we haven't seen before
