Which statement regarding vaccine-related side effects is accurate?

The option regarding the oral polio vaccine causing paralytic disease in immune deficient individuals is accurate because the oral polio vaccine (OPV), which is a live attenuated vaccine, can in rare cases lead to vaccine-derived poliovirus, particularly in individuals who are immunocompromised. In these cases, the weakened virus in the vaccine may replicate and potentially lead to a form of paralysis similar to that caused by the wild poliovirus. This scenario emphasizes the importance of careful consideration when administering live vaccines to individuals with specific health conditions, such as immune deficiency.

In contrast, other statements are not correctly represented. For instance, the inactivated influenza vaccine does not contain live virus and, therefore, cannot cause clinical influenza; the measles vaccine has undergone extensive research and has not been shown to be associated with autism; and thimerosal, a mercury-containing preservative used in some vaccines, has not been conclusively linked to mental retardation, leading health organizations to deem it safe in vaccines.
