If the vaccines don’t work why should we take boosters? This makes no sense what so ever.
I am not planning on a booster although I chose the one vaccine that has not had an official announcement of a booster. I had blood drawn three times and developed antibodies after 30 days. That's good enough for me, it means it "works". Vaccinated people getting COVID after taking risks is not proof that vaccines don't work. It is proof that vaccines were oversold, specifically the myth that COVID is less serious if you are vaccinated.
The numbers show that COVID is just as serious, 100 deaths in 10,000 cases in Mass. Those same numbers show the vaccines are very effective: 10,000 breakthrough cases in 4.4 million people vaccinated.
