Highlights from the article:
"Anyone who has had chickenpox – which is about 90 per cent of people born before 1995 – can develop shingles later in life, and about one-third do. The varicella zoster virus lies dormant for years, or decades, and erupts for reasons that are unclear, usually after age 50."

"Shingrix is a recombinant vaccine, produced with DNA technology. It also contains adjuvants (a substance added to a vaccine to increase the body's immune response), which may also explain why it is more effective. Unlike the old vaccine, it contains no live virus, and is safe for people who are immune-compromised."

"In a massive clinical trial of 37,000 patients, the Shingrix vaccine produced eye-popping results, especially when compared with data on Zostavax, the only other shingles vaccine on the market:
•In healthy adults aged 50-59, Shingrix reduced the likelihood of shingles by 97 per cent, compared with 70 per cent for Zostavax;
•In the 60-69 age group, it was 97 per cent versus 64 per cent;
•In the 70-79 age group, Shingrix was 91 per cent effective, compared with 41 per cent for Zostavax;
•In the over-80s, it was Shingrix was five times more effective – 91 per cent versus 18 per cent for Zostavax."
