A bold statement backed by decades of science and a healthy dose of sarcasm. This black button (or magnet) reads: “Vaccines cause adults”. A hilarious clapback to anti-vax nonsense and a celebration of growing up with basic healthcare. Perfect for doctors, science nerds, and anyone who survived childhood thanks to modern medicine. Stick it on your lab coat, backpack, or fridge and let the facts do the trolling. Pairs well with everyday skepticism, evidence‑based humor and peer‑reviewed sass.
