A nurse is reinforcing teaching with a client who is postpartum about the measles, mumps, and rubella (MMR) vaccine. Which of the following instructions should the nurse include in the teaching?

A. "If you are allergic to gluten you should not receive this vaccine." Gluten allergy is not a contraindication for the MMR vaccine. The vaccine does not contain gluten, and an allergy to gluten would not prevent someone from safely receiving the vaccine. However, individuals with severe allergies to neomycin or gelatin (which are components of the vaccine) should not receive it. B. "Avoid pregnancy for at least 28 days after receiving the vaccine." The MMR vaccine contains live attenuated viruses, and there is a theoretical risk to the fetus if a woman becomes pregnant shortly after vaccination. Therefore, it is recommended that women avoid becoming pregnant for at least 28 days after receiving the MMR vaccine to reduce any potential risks. C. "Avoid breastfeeding for 3 days after receiving the vaccine." The MMR vaccine is safe for breastfeeding mothers and does not require any interruption in breastfeeding. The vaccine viruses are not transmitted through breast milk in a way that would harm the infant. D. "Your partner should also receive the MMR vaccine." While it is important for all individuals to be up-to-date on their vaccinations, the partner's vaccination status is unrelated to the postpartum administration of the MMR vaccine to the client. This instruction does not address a specific concern related to the postpartum period or the MMR vaccine's administration at this time.
