The nurse is reinforcing teaching with a client who is postpartum about the rubella vaccine. Which statement should the nurse include?

• A. You can become pregnant immediately after vaccination
• B. You should delay breastfeeding for 1 month
• C. You must not become pregnant for 28 days after receiving this immunization
• D. The vaccine has no restrictions for pregnancy

Answer: (C)

Postpartum rubella vaccination uses a live attenuated vaccine, so there is a precaution about conceiving after receiving it. To minimize any theoretical risk to a fetus, you should not become pregnant for about 28 days following the shot. That’s why the statement about not becoming pregnant for 28 days after immunization is the correct guidance. It’s also safe to breastfeed after vaccination, and there’s no need to delay breastfeeding. The other options don’t fit because immediate pregnancy after vaccination is not advised, and there’s a specific 28-day pregnancy avoidance period rather than no restrictions or delays to breastfeeding.
