Depression may lower the effectiveness of the shingles vaccine, a new study found.
The research showed that adults with untreated depression who received the vaccine mounted a relatively weak immune response. But those who were taking antidepressants showed a normal response to the vaccine, even when symptoms of depression persist.
Shingles, an acute and painful rash, strikes a million Americans each year, mostly older adults. Health officials recommend that those over 60 get vaccinated against the condition, which is caused by reactivation of the same virus that causes chickenpox, varicella-zoster.
In the new study, published in the journal Clinical Infectious Diseases, researchers followed a group of 92 older men and women for two years. Forty of the subjects had a major depressive disorder; they were matched with 52 control subjects of similar age. The researchers measured their immune responses to the shingles vaccine and a placebo shot.
Compared with the control patients, those with depression were poorly protected by the vaccine. But the patients who were being treated for their depression showed a boost in immunity — what the researchers called a “normalization” of the immune response. It is unclear why that was the case.
The authors of the study speculated that treatment of older people with depression might increase the effectiveness of the flu shot and other vaccines as well.
