What is true regarding the Varicella vaccine?

The Varicella vaccine is designed to protect against chickenpox and is especially important for individuals who may not have developed immunity through previous infection or vaccination. When it comes to women who are pregnant or considering pregnancy, it is crucial to address immunity to Varicella.

Women who do not have immunity to Varicella should indeed receive the first dose of the vaccine upon completion of pregnancy. This timing is recommended to ensure that the vaccine does not pose any risk to the fetus during pregnancy and allows the mother to develop immunity to protect both herself and her future children from chickenpox.

This approach is aligned with public health recommendations, as the Varicella vaccine is a live attenuated virus vaccine and is not recommended during pregnancy due to the potential risks to the developing fetus. Therefore, vaccinating after pregnancy ensures that the woman can still gain immunity without any adverse effects on the pregnancy.

The other answer choices do not accurately reflect the correct information about the Varicella vaccine, making them less suitable answers to the question.
