The Centers for Disease Control and Prevention recommends that people 50 and older get the new shingles vaccine whether or not they remember having had chickenpox as a child. Those who never had chickenpox but did get the vaccine for it may also be susceptible to shingles because the vaccine contains a weakened live virus. However, the risk of shingles for those who had the chickenpox vaccine is much lower than for people who had the natural infection. Thus, if the result is positive, Dr. Leipzig says you’d be wise to get the shingles vaccine because you could be harboring the live virus. Lest you have doubts about the value of this vaccine, consider the effects of shingles.
