People can receive vaccinations against the shingles virus, though experts advise against one popular option until patients are about 60 years old. The vaccines offer protection for approximately five years but do not guarantee that shingles won't occur. If a vaccinated person develops shingles, however, the vaccine lessens the duration and severity of the illness. Doctors administer shingles injections as a preventative measure, not as a treatment for the active virus, and pregnant women or people who've never had chickenpox should not get the shingles vaccine.
