This immunization schedule is a handy reference to help you keep track of which vaccines your child needs to receive and when.
Types of Vaccines
Four different types of vaccines are currently available:
- Attenuated (weakened) live viruses are used in some vaccines such as in the measles, mumps, and rubella (MMR) vaccine.
- Killed (inactivated) viruses or bacteria are used in some vaccines, such as in IPV.
- Toxoid vaccines contain a toxin produced by the bacterium. For example, the diphtheria and tetanus vaccines are toxoid vaccines.
- Conjugate vaccines (such as Hib) contain parts of bacteria combined with proteins.
Immunizations for Travel
Specific information about which immunizations are required by travelers to each country worldwide is available directly from the Centers for Disease Control and Prevention (CDC). Ask your doctor for more information.
Depending on the type and length of travel, some vaccines may be recommended. Most immunizations should be given at least 1 month before travel. Take your child's immunization records with you when you travel internationally.
