At what age should individuals be vaccinated against Herpes Zoster Ophthalmicus?

The correct age for vaccination against Herpes Zoster Ophthalmicus involves a focus on individuals who are at higher risk for developing complications from the herpes zoster virus, particularly the risk of ocular involvement. The vaccine, Shingrix, is recommended primarily for adults aged 50 years and older, but initiating vaccination at 60 years is also prevalent.

However, the rationale for the option stating vaccination at 70 years, with a top-up at 79 years, is rooted in the increased risk of complications as individuals age, particularly for those who have a higher likelihood of developing conditions like postherpetic neuralgia and zoster ophthalmicus. The later age group at which the vaccine is given ensures that individuals are provided with optimal protection just as their immune function tends to decline with age, leading to an increased susceptibility to infections.

This also aligns with guidelines which often emphasize the importance of receiving a booster or a top-up vaccine, as immunity to viruses can weaken over time. Thus, vaccinating at 70 years and considering an additional dose at 79 years not only enhances protection but also addresses the need for sustained immunity in an aging population particularly vulnerable to serious outcomes from herpes zoster infections.
