In such cases, Tdap is recommended to be substituted for one dose of Td, again preferably between 27 and 36 weeks of gestation, and then the series completed with Td. Specific types
The first vaccine is given in infancy. The baby is injected with the DTaP vaccine, which is three inactive toxins in one injection. DTaP protects against diphtheria, pertussis, and tetanus. This vaccine is safer than the previously used DTP. Another option is DT, which is a combination of diphtheria and tetanus vaccines. This is given as an alternative to infants who have conflicts with the DTaP vaccine. Quadrivalent, pentavalent, and hexavalent formulations contain DTaP with one or more of the additional vaccines: inactivated polio virus vaccine (IPV), Haemophilus influenzae type b conjugate, Hepatitis B, with the availability varying in different countries.For the every ten-year booster Td or Tdap may be used, though Tdap is more expensive. Schedule
Because DTaP and DT are administered to children less than a year old, the recommended location for injection is the anterolateral thigh muscle. However, these vaccines can be injected into the deltoid muscle if necessary.The World Health Organization (WHO) recommends six doses in childhood starting at six weeks of age. Four doses of DTaP are to be given in early childhood. The first dose should be around two months of age, the second at four months, the third at six, and the fourth from fifteen to eighteen months of age.
