In its November 2017 update, the Quebec Immunization Protocol tells us that it is possible to vaccinate a person regardless of their history of chickenpox. Whether or not you had chickenpox when you were young is unlikely to change the side effects you may experience after the injection (muscle pain, fatigue, headaches). These side effects are more common in people your age than in people over 70. However, you should know that most people do not suffer from these effects after about 3 days.
