She includes the bit about whooping cough at the Los Angeles school but the numbers don't tells us anything about the likelihood the 18 unvaccinated would've had contact with those 30 who contracted the illness.
CDC tells us the booster shot protects 70% in the first year and 40% four years after receiving it so it's "good" but not fool proof.
