From 2013, the UK National Health Service (NHS) started offering shingles vaccination to elderly people. People aged either 70 or 79 on 1 September 2013, were offered the vaccine. People aged 71 to 78 on that date would only have an opportunity to have the shingles vaccine after reaching the age of 79. The original intention was for people aged between 70 and 79 to be vaccinated, but the NHS later said that the vaccination program was being staggered as it would be impractical to vaccinate everyone in their 70s in a single year.In 2021, vaccination against shingles is available on the NHS to people aged 70 to 79. Vaccination is with single-dose Zostavax, except for people for whom Zostavax is deemed unsuitable, for example, with a condition that affects the immune system, for whom two-dose Shingrix vaccine is recommended. The NHS stated "The shingles vaccine is not available on the NHS to anyone aged 80 or over because it seems to be less effective in this age group". United States
Zostavax was developed by Merck & Co. and approved and licensed by the U.S. Food and Drug Administration (FDA) in May 2006, In 2011, the FDA approved the live vaccine for use in individuals 50 to 59 years of age. Shingrix is a zoster vaccine developed by GlaxoSmithKline that was approved in the United States in October 2017.On June 30, 2020, Merck discontinued the sale of Zostavax in the U.S.
Vaccine already held by practitioners could still be administered up to the expiration date (none expired later than November 2020).The U.S. Centers for Disease Control and Prevention (CDC) recommends that healthy adults 50 years and older get two doses of Shingrix, at least two months apart. Initial clinical trials only tested a gap of less than six months between doses, but unexpected popularity and resulting shortages caused further testing to validate wider spacing of the two doses. Shingrix, which provides strong protection against shingles and PHN, was preferred over Zostavax before Zostavax was discontinued.The zoster vaccine is covered by Medicare Part D. In 2019, more than 90% of Medicare Part D vaccine spending was for the zoster vaccine. 5.8 million vaccine doses were administered to Part D beneficiaries that year at a cost of $857 million.
