In 2013, a program of vaccination against infections with Herpes zoster (chicken pox, shingles, postherpetic neuralgia that is less) has been introduced in England for adults aged 70 years, for the prevention of herpes zoster and postherpetic neuralgia that is less.
In this study, the researchers extracted data from the primary health care network the Royal College of General Practitioners consultation of patients aged 60 to 89 years of age for varicella and postherpetic neuralgia that is less. The study, carried out on public funds, has been published in the journal The Lancet Public Health.
To do this, they have identified individual-level data on vaccinations. Then, they reported to the vaccine coverage estimated for the vaccination and consultations. Several search criteria were selected to assess the consequences of : age, area, sex, time period, and the availability of the vaccine.
Very interesting results
The analysis focused on more than three million people have consulted their general practitioner over three years. To August 31, 2016, the coverage of vaccination against herpes zoster in the population over 65 years varies between 58% for the cohorts recently targeted and 72% for the first cohort vaccinated.
During the first three years of follow-up of vaccination on the cohort originally targeted, the incidence of herpes zoster has decreased by 35% and the postherpetic neuralgia that is less than 50%.
The program of vaccination against herpes zoster in England has had an impact on the population, equivalent to about 17 000 episodes of zoster less and 3 300 episodes of postherpetic neuralgia that is less and less in 5.5 million people.
These results are particularly interesting for the prevention of herpes zoster and, in particular, of the postherpetic neuralgia that is less, a chronic illness that is very disabling and very difficult to treat.
