What vaccines are typically given at 4 years of age?

The vaccines typically administered at 4 years of age include a combination of immunizations that are crucial for protecting children against multiple serious infections. The correct choice encompasses the Diphtheria, Tetanus, Pertussis (DTaP) vaccine and the Measles, Mumps, and Rubella (MMR) vaccine.

The DTaP vaccine is important as it helps protect against three potentially life-threatening bacterial diseases: diphtheria, tetanus, and whooping cough (pertussis). These diseases can lead to severe complications, particularly in young children, making the DTaP a core part of childhood immunizations.

The MMR vaccine, administered around 4 years of age, provides immunity against three viral infections that can cause significant morbidity and complications, especially measles, which can lead to serious complications like pneumonia and encephalitis.

This combination of vaccines at 4 years old is aligned with the recommendations from health authorities to ensure children are adequately protected before they enter school settings, where they may be exposed to these diseases.

The other options listed do not fully represent the vaccines that are standard for this age group, particularly those that include the critical MMR vaccine alongside DTaP.
