Which live vaccines should be avoided for 11 months in a child diagnosed with Kawasaki disease?

The correct answer is B: (MMR) vaccine and Varicella vaccine. Children diagnosed with Kawasaki disease should avoid live vaccines due to potential risks of triggering a recurrence of the disease. MMR and Varicella vaccines are live vaccines, so they should be avoided for 11 months post-diagnosis. Polio and Hepatitis vaccines are not live vaccines and do not pose the same risk. Influenza vaccine is also not a live vaccine, but it is not relevant to this specific scenario. Therefore, the correct choice is B, as it aligns with the precautionary measures to prevent complications in children with Kawasaki disease.
