Which of the following individuals are contraindicated from receiving the MMR vaccine?

The MMR vaccine, which protects against measles, mumps, and rubella, is a live attenuated vaccine and is generally contraindicated in certain populations. In this case, the individual in her third trimester of pregnancy should not receive the MMR vaccine. This is due to the potential risk to the fetus, as live vaccines like MMR could theoretically be harmful if given to pregnant women.

Pregnant individuals are advised to wait until postpartum to receive the MMR vaccine to ensure the safety of the developing fetus.

While the other options contain individuals with various health conditions, they do not have the same degree of risk associated with the vaccination as a pregnant individual does. Therefore, the contraindication for the MMR vaccine primarily applies to the individual in her third trimester.
