The vaccines do work. It is statements like this that reveal you’re one of the people who got played.
There is data. But there is no data past about a year for obvious reasons. Do you get your science from reading actual data or from some media hack who want to stir things up? Whoever has told you the vaccines don’t work has lied to you. You can decide if it was intentional or accidental.
It depends on how you define "work". They don't keep you from getting COVID. They do have some effectiveness in keeping it from being severe. But even that is being questioned.

This could suggest that it is less effective against Delta or possibly waning over time, which has added to a debate about whether booster shots may be needed and for whom. All of this is still being monitored.
But since we don't know what a "case" is and most infections are asymptomatic and most people with no symptoms don't get tested we have no idea who has it, how effective the vaccine really is, how long it lasts, how its effectiveness changes over time, how effective it is on the various varieties, whether its effectiveness changes based on demographics, general health of the person, diet, supplements, other conditions, other vaccines, and on and on.
They do work? How do you know? Yes, I got my two shots and a booster. I'm doing what I believe is the right thing for me and those close to me. But I still have VERY grave doubts about big pharma and government policymakers driving the conversation. Is it effective? I don't know. Will it be effective in the future? I don't know. Does it cause side effects? I don't know. Does it cause SEVERE side effects? I don't know. And neither does anyone else.
