Infanrix Dosage

Dosing guidelines for Infanrix recommend five separate injections given at the age of 2 months, 4 months, 6 months, 15 to 20 months, and 4 to 6 years. However, some flexibility is allowed with this schedule. The first Infanrix dosage can be given to babies as young as six weeks old, and the last dose can be delayed up until a child's seventh birthday.

Dosing With Infanrix: An Introduction

There is only one standard dosage for Infanrix® (DTaP), although there is some flexibility in the exact vaccination schedule.

Ideal Infanrix Vaccine Schedule

The recommended Infanrix dosage is five doses (each one 0.5 mL injected into a muscle) at the following ages:
  • 2 months
  • 4 months
  • 6 months
  • 15 to 20 months
  • 4 to 6 years.

Other Vaccination Schedules

Some variability is allowed with this particular vaccine. The first dose can be given to infants as young as six weeks old. The last dose can be delayed slightly, up until the child's seventh birthday, but a different vaccine (either the Tdap or the Td vaccine, depending on the age of the individual) is recommended after the age of seven.
The Centers for Disease Control (CDC) also allows the fourth dose to be given as early as 12 months of age, as long as six months have passed since the third dose.
If you choose a delayed vaccination schedule (or your child's vaccines are interrupted for any reason), there is no reason to "start over," regardless of how much time has elapsed.

General Information on Infanrix Dosages

Some considerations for people receiving Infanrix include the following:
  • This vaccine is typically given as a five-dose series. The first dose usually occurs at two months of age, and the fifth dose is given between four and six years of age.
  • For infants, Infanrix is injected into a muscle (intramuscularly), usually in the thigh. In older children, the upper arm can be used.
  • Children can be vaccinated if they have a minor illness, such as the common cold. However, the vaccine should be postponed if the child is moderately or severely ill.
  • If you are unsure about anything related to Infanrix dosing, please talk with your doctor, nurse, or pharmacist.
