When should adults be vaccinated against chickenpox?

ANSWER

All adults who have never had chickenpox or received the vaccination should be vaccinated against it. Two doses of the vaccine should be given at least four weeks apart. If you've never had chickenpox or been vaccinated and you are exposed to chickenpox, being vaccinated right away will greatly reduce your risk of getting sick. Studies have shown that vaccination within three days of exposure is 90% effective at preventing illness; vaccination within five days of exposure is 70% effective. If you do get sick, the symptoms will be milder and shorter in duration.
