congrats mukesh and mr anonymous

THE CORRECT ANSWER IS
D-Measles vaccine



It’s a pretty complicated question which tests your knowledge of vaccines needed for international travel, vaccine contraindication in HIV and vaccines made using egg protein.



Vaccines that contain live, attenuated viruses should not be given to pregnant women or persons who are immunodeficient or who are potentially immunodeficient like in HIV. Oral typhoid and oral polio vaccines are both live, attenuated vaccines and should not be given to an HIV-positive individual. An alternative to both vaccines is the killed parenteral vaccines. Yellow fever is also a live vaccine; the risks of the use of this vaccine in HIV-infected patients have not been established. However, severe allergic reaction to egg proteins is a contraindication for yellow fever vaccinations, and therefore, that vaccine should not be

given to this person. Some countries in South America may require proof of yellow fever vaccination, and the patient should be advised of this before travel. The one exception to the use of live, attenuated vaccines in immunocompromised individuals is measles vaccinations. Measles can be severe in HIV-positive patients, and therefore, measles immunization should be provided if the patient is not severely immunocompromised (i.e AIDS) and if he was immunized for measles before 1980.
