Brief summary

Hepatitis A vaccine will be given either alone or together with measles, mumps, rubella, and varicella vaccine and pneumococcal 7-valent conjugate vaccine at the first dose and together with measles, mumps, rubella, and varicella \[Oka/Merck\] virus vaccine at the second dose. Immunogenicity and safety data will be collected after each dose of vaccine.

Detailed description

Vaccines: V251, Hepatitis A Vaccine, Inactivated (VAQTA™) administered with Measles, Mumps, Rubella and Varicella Vaccine (ProQuad™) and Pneumococcal 7-Valent Conjugate Vaccine (Prevnar™) will have a Duration of Treatment: 2 Doses, 6 months apart. Vaccine: Hepatitis A Vaccine, Inactivated (VAQTA™), administered alone will have a Duration of Treatment: 2 Doses, 6 months apart.
