At what age is the herpes zoster vaccine first recommended for immunocompetent adults?

The herpes zoster vaccine is first recommended for immunocompetent adults at the age of 50 years. This recommendation is based on research demonstrating that the risk of developing herpes zoster, also known as shingles, increases with age. The vaccine is designed to boost the immune response to the varicella-zoster virus (the virus that causes chickenpox and shingles), thus helping to prevent the onset of the disease as well as its complications, such as postherpetic neuralgia.

By immunizing adults starting at 50, healthcare providers aim to reduce the incidence and severity of shingles in the adult population, which is particularly pertinent because individuals over the age of 50 are more likely to experience severe symptoms and long-term complications from shingles.

The other age suggestions for vaccination do not align with the current guidelines; options below 50 do not adequately capture the increased risk that begins at that age. As such, the recommendation at age 50 strikes the appropriate balance between public health objectives and individual health risk management.
