Question 1 of 5
In addition to pertussis vaccination, which vaccine when given to pregnant women has been shown to reduce the likelihood of disease in their infants up to 3 months of age?
Correct Answer: B
Rationale: Maternal influenza vaccination (Choice B) reduces infant influenza risk up to 3 months via transplacental antibody transfer, with evidence showing significant protection against severe disease. Hepatitis B (Choice A) vaccination protects against chronic infection, not acute infant disease. Measles (Choice C) vaccination isn’t given in pregnancy due to live virus risks. Meningococcal B (Choice D) lacks robust data for infant protection via maternal immunization. Influenza’s proven efficacy makes it the correct choice.
