If a patient is breast-feeding her six-month-old baby, can she receive varicella vaccine without the risk of transmitting the vaccine virus to her baby?

There has been only one published report of mother to child transmission of varicella vaccine virus. If the susceptible woman were to be infected with wild varicella virus, the risk of transmission to the infant would be much higher. Breastfeeding is not a contraindication or a precaution to varicella vaccination of the mother when vaccination is indicated.
