How many vaccines are routinely used for laboratory rodents?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: (A)

Routine vaccination of laboratory mice and rats is not performed in standard practice. In these species, vaccines that are approved or widely used are limited, and many can alter immune responses and potentially confound experimental results. Because most colonies are kept in barrier, pathogen-free conditions and are maintained through health surveillance, quarantine, and strict biosecurity rather than vaccination, there is little justification for routine vaccination. Vaccination is considered only in specific cases where a clear, unavoidable risk exists and after weighing any potential impact on the study. This is why zero vaccines are routinely used for laboratory rodents.
