Which of the following vaccines is administered as part of the MMR vaccination?

The MMR vaccination is specifically designed to protect against three viral diseases: measles, mumps, and rubella. The inclusion of mumps in the MMR vaccination is essential, as it helps to prevent the outbreaks and complications associated with the disease, which can include swelling of the salivary glands, fever, and, in some cases, more severe health issues. As part of the routine childhood immunization schedule, the MMR vaccine plays a crucial role in maintaining community immunity and preventing the resurgence of these diseases. The other options relate to different diseases and vaccination protocols: tetanus is included in the DTaP vaccine, varicella protects against chickenpox, and hepatitis B is given as a separate vaccine, none of which are components of the MMR vaccine.
