The correct answer is D. Varicella.Choice A rationaleRotavirus vaccination is typically administered in infancy, not at 5 years of age. The rotavirus vaccine is given to infants to protect against rotavirus infections, which can cause severe diarrhea and dehydration in young children. By the age of 5, children have usually completed the rotavirus vaccination series.Choice B rationaleHepatitis B vaccination is also typically completed in infancy. The hepatitis B vaccine is given to infants to protect against hepatitis B virus infection, which can cause chronic liver disease and liver cancer. By the age of 5, children who are up-to-date with their immunizations have usually completed the hepatitis B vaccination series.Choice C rationaleHaemophilus influenzae type b (Hib) vaccination is typically completed by 15 months of age. The Hib vaccine protects against infections caused by Haemophilus influenzae type b, such as meningitis, pneumonia, and epiglottitis. By the age of 5, children who are up-to-date with their immunizations have usually completed the Hib vaccination series.Choice D rationaleThe second dose of the varicella vaccine is usually given at 4-6 years of age.
