From the Guidelines
At 1 year of age, children should receive the MMR (Measles, Mumps, Rubella), Varicella (Chickenpox), and Hepatitis A vaccines, as these provide crucial protection against serious illnesses. The MMR and Varicella vaccines are particularly important as they protect against highly contagious diseases that can have severe complications in young children 1. According to the Advisory Committee on Immunization Practices (ACIP), the first dose of MMR and Varicella vaccines should be administered at age 12-15 months, and the second dose at age 4-6 years 1.
For the first dose of measles, mumps, rubella, and varicella vaccines at age 12-47 months, either MMR vaccine and varicella vaccine or MMRV vaccine may be used, but the CDC recommends that MMR vaccine and varicella vaccine should be administered for the first dose in this age group unless the parent or caregiver expresses a preference for MMRV vaccine 1. The Hepatitis A vaccine is also recommended at 1 year of age, as a 2-dose regimen, and can be administered concurrently with other vaccines 1.
Key points to consider when administering these vaccines include:
- The MMR and Varicella vaccines can be administered as separate injections or as a combination MMRV vaccine 1
- The Hepatitis A vaccine should be administered as a 2-dose regimen, with the first dose at 12-23 months of age 1
- Immunocompromising conditions are not a contraindication to receiving the Hepatitis A vaccine, but a hypersensitivity to any of the vaccine components is a contraindication 1
- The vaccines should be administered according to the approved schedules, and the child's immunization record should be updated accordingly 1
From the Research
Vaccinations Recommended at 1 Year of Age
- The studies provided do not directly address the vaccinations recommended at 1 year of age 2, 3, 4, 5, 6.
- However, the studies discuss the effectiveness and safety of vaccines for measles, mumps, rubella, and varicella in children, which are typically administered in the first two years of life 3, 4, 5, 6.
- According to the studies, two doses of the combined measles-mumps-rubella-varicella vaccine (MMRV) are effective in preventing varicella, with a vaccine efficacy of 95% after two doses 3, 4, 5.
- The American Academy of Pediatrics recommends that children receive the MMRV vaccine at 12-15 months of age and again at 4-6 years of age, but the exact timing may vary depending on the child's health status and other factors.
- It is essential to consult with a healthcare professional to determine the recommended vaccinations for a child at 1 year of age, as the specific vaccines and schedule may vary depending on individual circumstances.
