Immunizations and Antibiotics for Oversea Travel (cont.)

Specific Vaccine Notes

  • Most vaccine courses can be interrupted without the need for extra doses. (Typhoid is an exception.)
  • Typhoid vaccination is not required for international travel but is recommended for anyone older than 2 years of age. Breastfeeding infants is a way to protect them against infection from water sources. Infants who are not breastfed should have carefully prepared formula and food.
  • The hepatitis A vaccination should be given to travelers older than 2 years of age. It is now part of routine vaccinations; however, for travelers who are older than 10 years of age, they may not have received the vaccination as a child. The disease is much less severe in children younger than 5 years of age compared with adults. For children younger than 2 years of age, the hepatitis A immunoglobulin should be given to confer passive immunity and protection.
  • Some African countries require proof of yellow fever vaccination prior to entering the country. Note that infants younger than 9 months of age cannot be immunized for this because of the risk of contracting encephalitis. Travelers with infants in this age group are strongly advised against traveling to areas with endemic yellow fever.
