Tetravac is a vaccine that helps protect children against diphtheria, tetanus, whooping cough, and polio by helping their body build defenses.
For young children, it's usually 2 or 3 shots given a few months apart, followed by a booster at 12 months. An additional booster is recommended between 4-13 years of age.
A doctor or nurse will give this vaccine as a shot into your child's thigh or upper arm muscle. It should never be injected into a blood vessel.
Only one dose of the vaccine is given at each scheduled visit.
