Which immunizations are generally administered at 12-15 months of age?

The immunizations administered generally at 12-15 months of age include the measles, mumps, and rubella (MMR) vaccine, the pneumococcal conjugate vaccine (PCV), and the inactivated poliovirus vaccine (IPV). This immunization schedule reflects recommendations from health organizations that aim to protect children during this critical stage of development.

At around 12-15 months, children are at an increased risk for infections such as measles and pneumococcal disease. The MMR vaccine is highly effective and is usually given at this age to initiate protection against these serious contagious diseases. Similarly, the PCV vaccine helps to reduce the risk of pneumococcal diseases, which can lead to complications such as pneumonia and meningitis. IPV further boosts immunity against polio, an important step in preventing this debilitating disease.

The other immunization schedules listed do not align with the standard recommendations for this age group. For example, while Hepatitis A and Hib may be relevant immunizations, they are typically administered at different times during infancy and early childhood rather than specifically at 12-15 months. Therefore, the combination of IPV, PCV, and MMR correctly reflects the immunization schedule at this developmental stage.
