  • Prefilled syringe offers healthcare professionals a convenient administration option
  • New presentation will begin rolling out across EU countries in 2026
  • Shingles affects approximately 1.7 million people in Europe each year,1 with certain chronic conditions linked to a higher risk of shingles2,3

GSK plc (LSE/NYSE: GSK) today announced the European Commission’s (EC) approval of Shingrix (GSK’s Recombinant Zoster Vaccine or RZV) in a prefilled syringe. The current vaccine presentation comprises two vials, one with a lyophilised powder antigen and another with a liquid adjuvant. The lyophilised powder antigen requires reconstitution, where the suspension in the adjuvant vial is withdrawn and injected into the antigen vial. The new prefilled syringe simplifies the vaccine administration process for healthcare professionals by removing the need to undertake these steps prior to administration.

Tony Wood, Chief Scientific Officer, GSK, said: “This new presentation of Shingrix has been designed to improve ease of administration, helping healthcare professionals to provide protection against shingles. Shingles is a painful disease that can have serious and long-lasting complications. It affects millions of people each year in Europe, often imposing a greater burden on people living with common chronic diseases such as cardiovascular disease and diabetes. GSK is proud to support the healthcare community by making administration of its shingles vaccine easier."
 
This approval is based on data confirming technical comparability between the prefilled syringe and the existing vaccine presentation.4 The new presentation does not involve a change in indication or dosing.

About shingles

Shingles is caused by the reactivation of the varicella-zoster virus (VZV), the same virus that causes chickenpox.2 Globally, up to 1 in 3 adults will develop shingles in their lifetime.2,5,6,7 Over 90% of adults have the VZV dormant in their nervous system, waiting to reactivate.2,8,9,10 In addition to advancing age, chronic conditions like cardiovascular disease, chronic kidney disease, chronic obstructive pulmonary disease, asthma, and diabetes are all linked to higher risk of shingles.2,3

Shingles typically presents as a rash, with painful blisters across the chest, abdomen or face.8 Following the rash, up to 30% of people experience post-herpetic neuralgia (PHN),11 a long-lasting nerve pain that can last weeks or months and can occasionally persist for several years.2

About Shingrix (Recombinant Zoster Vaccine or RZV)

Shingrix combines an antigen, glycoprotein E, with an adjuvant system, AS01B, and may help overcome the natural age-related decline in responses to immunisation that contributes to the challenge of protecting adults aged 50 and over from shingles.12,13 RZV is not indicated to prevent primary varicella infection (chickenpox). The use of RZV should be in accordance with official recommendations and local product label.

GSK’s shingles vaccine has been approved in the European Union for the prevention of herpes zoster (HZ) and PHN in adults aged 50 years or older since 2018; and in adults 18 years or older at increased risk of HZ, since 2020.
