Act Hib

The usual dose of this vaccine is 0.5 mL given as an injection into the muscle of the outer thigh or the outer side of the upper arm. Depending on when your child starts their immunization (vaccination) series, the number of doses they receive may be different.

This vaccine is given by a health care professional in a doctor's office, hospital, or clinic.

When immunization begins at 2 months to 6 months of age, 3 doses should given (0.5 mL per dose): the first dose is given at the initial visit, the second dose 2 months later, and the third dose 4 months after the initial visit. A booster dose is recommended between 15 and 18 months of age.

Children between the ages of 7 months to 11 months who have not previously received the vaccine should be given 2 doses (0.5 mL per dose): the first dose is given at the initial visit, followed by a second dose 1 month later. A booster dose should be given sometime between 15 and 18 months of age.

Children between the ages of 12 and 14 months who have not previously received the vaccine should be given 1 dose (0.5 mL per dose).  A booster dose is recommended at or after 18 months of age.

Children between the ages of 18 months and 5 years who have not previously received the vaccine should be given 1 dose (0.5 mL) only.

It is very important that this vaccine be given on a regular schedule as prescribed by the doctor. If your child misses a dose of this vaccine, check with your child's health care professional. Add all vaccines your child receives to their immunization record.
