People are not vaccinated at birth, so even with 100% effective vaccination really young children are still at risk. However, the reality is vaccinations while effective are not perfect so there is are range protection. AKA, Some poeple while at lower risk of infection can still get sick with prolonged exposure.
PS: A fire resistant couch save lives dispute the fact they can still burn in a hot enough fire, the benefit is focused on small ignition sources aka a spark or cigarette not a kiln.
right so we vaccinate even though theres a low chance of contracting a disease, a significant chance that the vaccination will cause side effects and a chance that it might not work anyway. Makes sense to me!
EX: Just the M in MMR prevents ~1/2 million people from getting sick each and every year. The benefit of measles vaccination in preventing illness, disability, and death has been well-documented. The first 20 years of licensed measles vaccination in the U.S. prevented an estimated 52 million cases of the disease, 17,400 cases of mental retardation, and 5,200 deaths.[10] During 1999–2004, a strategy led by the World Health Organization and UNICEF led to improvements in measles vaccination coverage that averted an estimated 1.4 million measles deaths worldwide.[11]
Vaccinations prevent well over 50,000 deaths per year in the US alone along with a large number of vary serious side effects. On an individual basis the lifetime chance of infection is still higher than you might think and only increases as more people avoid vaccination. If we where talking about an adult taking the risks for themselves that's one things, but we are talking about making the choice for someone else as well increasing the overall risk to society.
