What type of vaccines can be administered?

The ability to administer both live and inactivated vaccines supports a comprehensive immunization strategy. Live vaccines, which contain weakened forms of the virus or bacteria, are effective because they stimulate a strong and lasting immune response, often requiring fewer doses for long-term immunity. Examples include the measles, mumps, and rubella (MMR) vaccine, and the varicella (chickenpox) vaccine.

In contrast, inactivated vaccines consist of killed pathogens or components of the virus or bacteria, which may require multiple doses to achieve adequate immunity. Examples include the polio vaccine and the hepatitis A vaccine.

Having the flexibility to use both types of vaccines allows healthcare providers to tailor vaccinations according to specific needs, considering factors like age, health status, and existing immunity levels in the population. This approach helps ensure broader protection against various diseases, optimizing public health outcomes.

The options focused solely on live vaccines, solely on inactivated vaccines, or vaccines from international sources limit the scope of immunization practices and do not reflect the diverse range of vaccines available to meet different healthcare needs.
