As I said in another thread, your sons will soon be injecting more dangerous live bacteria into their small bodies than all the vaccinations they will ever get. Babies put things in their mouth, and small children play in dirt and step on rusty nails. It always happens. If you do not give them a DPT shot you are risking tetanus, which is a horrible way to die. So I hope this delay is not long.

Parents who forgo vaccinations completely usually get a free ride with measles or mumps. They can count on other parents acting responsibly. Sure, they still endanger the child for no reason, and exposing him to far greater risk than the vaccination would, but the chances are they will get away with it. But tetanus is as prevalent as it ever was.
