Tripedia Dosage

The recommended dosing schedule for Tripedia calls for five injections, typically given at the age of 2 months, 4 months, 6 months, 15 to 20 months, and 4 to 6 years. Some variability is allowed with this vaccine, as long as there is at least 4 to 8 weeks between the first three Tripedia dosages and 6 to 12 months between the third and fourth doses.

Tripedia Dosing: An Introduction

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

Tripedia Vaccination Schedule

The standard Tripedia dosing schedule consists of five injections, usually given at the following ages:
 
  • 2 months
  • 4 months
  • 6 months
  • 15 to 20 months
  • 4 to 6 years.
     
Each dose consists of 0.5 mL injected into a muscle (intramuscularly). The fourth dose, if given between the ages of 15 and 18 months, is approved to be mixed together with ActHIB®, a Haemophilus influenzae type b vaccine (Hib vaccine).
 
Some variability is allowed with Tripedia. 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.
 
There should be at least 4 to 8 weeks between the first three doses and 6 to 12 months between the third and fourth doses. In general, if the fourth dose is given after the age of four, a fifth dose is unnecessary.
