What immunization would carry the greatest risk for immunocompromised patients?

Live attenuated vaccines carry the greatest risk for immunocompromised patients. These vaccines contain a weakened form of the virus or bacteria, which can potentially cause disease in individuals with weakened immune systems. Examples include the measles, mumps, rubella (MMR) vaccine and the varicella (chickenpox) vaccine. It is crucial for immunocompromised individuals to consult their healthcare providers for appropriate immunization strategies.
