A. Measles
B. Mumps

Textbook Explanation Highlight:
The classic triad of fever, rash, and parotitis strongly points towards Mumps. While Measles causes fever and rash, parotitis is not a primary feature. Rubella also causes fever and rash but typically without parotitis. A single dose of MMR provides...

A 10-month-old child presents with bloody diarrhea and fever. Stool culture is positive for Rotavirus. The child received two doses of Rotavirus vaccine at 6 and 10 weeks of age. What is the most likely reason for this infection?
A. Vaccine failure due to inadequate immune response
B. Infection with a serotype not covered by the vaccine
C. The vaccine only prevents severe disease, not all infections
D. Improper storage of the vaccine rendering it ineffective
Textbook Explanation Highlight:
Rotavirus vaccines are highly effective in preventing severe rotavirus gastroenteritis, hospitalization, and death. However, they do not prevent all rotavirus infections or mild to moderate episodes. Breakthrough infections can occur, but they are ty...
