A nurse is providing discharge teaching to a postpartum client who had no immunity to rubella and received the rubella immunization. Which of the following statements by the client indicates an understanding of the teaching?

Choice A rationale A single dose of the rubella vaccine is typically sufficient to confer immunity. A second dose is not routinely recommended after postpartum administration. The primary goal is to prevent congenital rubella syndrome in future pregnancies by ensuring the mother develops adequate antibody titers to the virus. Choice B rationale The rubella vaccine contains live attenuated virus, which carries a theoretical risk of congenital rubella syndrome if the vaccine virus crosses the placenta during pregnancy. Therefore, clients are advised to avoid conception for at least 1 to 3 months, commonly stated as 4 months, after vaccination to minimize any potential fetal exposure. Choice C rationale The rubella immunization typically provides long-lasting immunity. It is not necessary to receive an additional rubella immunization during the first trimester of a subsequent pregnancy. Antibody titers are usually maintained, protecting against future rubella infection and subsequent fetal harm. Choice D rationale The rubella vaccine is considered safe for breastfeeding mothers and their infants. The live attenuated virus is not shed in breast milk in significant amounts that would pose a risk of infection to the infant. Therefore, breastfeeding can continue without interruption after rubella immunization.
