What is a characteristic of Vivotif vaccine?

The characteristic of Vivotif vaccine that highlights its unique administration route is oral administration. This means that the vaccine is delivered through the mouth rather than by injection, which is typical for many other types of vaccines. The oral route is particularly advantageous for ease of use and patient compliance, as it does not require needles and can often be taken at home.

In addition to its oral administration, Vivotif is also a live attenuated vaccine. This means it contains weakened forms of the bacteria that cause typhoid fever, which helps to stimulate an immune response without causing the disease in healthy individuals. The recommendation for use in non-immunocompromised individuals underscores the safety profile of this vaccine in the target population, as those who are not immunocompromised can safely receive live attenuated vaccines.

In contrast, inactivated vaccines do not use live pathogens and are administered differently, often requiring injections. Therefore, oral administration is a defining characteristic of Vivotif, setting it apart from many other vaccines.
