There are two Shingles vaccine, and one of these (Zostavax) is a live vaccine. Transmission to susceptible household contacts has been reported but is rare. The vaccine is however recommended for healthy susceptible contacts of immunocompromised patients where continuing close contact is unavoidable (e.g. siblings of a leukaemic child, or a child whose parent is undergoing chemotherapy). If in doubt check with your centre if they would be happy for you to be vaccinated, if the answer is yes, you need not worry about household contact transmission.
