Which of the following vaccines is specifically a combination vaccine?

The DPT vaccine, which stands for Diphtheria, Pertussis (whooping cough), and Tetanus, is classified as a combination vaccine because it contains more than one active component to provide immunity against multiple diseases. This approach simplifies vaccinations by allowing a child to receive protection from these three diseases in a single shot, rather than requiring separate vaccines for each illness.

Combination vaccines like the DPT are beneficial as they reduce the number of injections a child needs to receive, improving compliance and making the vaccination process less burdensome for families and healthcare providers. Each component of the DPT vaccine is crucial for preventing serious infections: diphtheria can cause throat swelling and airway blockage, pertussis is highly contagious and can be severe in infants, and tetanus is a serious condition that causes muscle stiffness and spasms.

In contrast, the other vaccines listed are not combination vaccines. The MV vaccine refers to the Measles vaccine, which specifically targets one disease. The BOP vaccine, which protects against diseases including Bordetella pertussis (separate from DPT), and Hib (Haemophilus influenzae type b) vaccine, which prevents a specific bacterial infection, also do not form combinations of multiple diseases within
