A 2024 study of over 200,000 older US adults found that the recombinant shingles vaccine was linked to a larger reduction in dementia compared to the live shingles vaccine. [56] Over a six-year follow-up, those who received the recombinant vaccine had a 17% increase in time without a dementia diagnosis compared to those who received the live ...
Schematic drawing of a Herpesviridae virion. All members of the Herpesviridae share a common structure; a relatively large, monopartite, double-stranded, linear DNA genome encoding 100–200 genes encased within an icosahedral protein cage (with T=16 symmetry) called the capsid, which is itself wrapped in a protein layer called the tegument containing both viral proteins and viral mRNAs and a ...

Influenza A virus structure. The influenzavirus virion is pleomorphic; the viral envelope can occur in spherical and filamentous forms. In general, the virus's morphology is ellipsoidal with particles 100–120 nm in diameter, or filamentous with particles 80–100 nm in diameter and up to 20 μm long. [5]
1975: Measles vaccination for 1 year old children. 1975: Rubella vaccination for 11–13 years old girls and seronegative mothers. 1982: Two doses of MMR vaccination at 14–18 months and 6 years of age were introduced in the national childhood vaccination programme. 2009: Rotavirus vaccine introduced at 2, 3 and 5 months to all children ...
Shingles, also known as herpes zoster or zona, [6] is a viral disease characterized by a painful skin rash with blisters in a localized area. [2] [7] Typically the rash occurs in a single, wide mark either on the left or right side of the body or face. [1]
Research has gone into vaccines for both prevention and treatment of herpes infections. As of October 2022, the U.S. FDA have not approved a vaccine for herpes. [123] However, there are herpes vaccines currently in clinical trials, such as Moderna mRNA-1608. [124] Unsuccessful clinical trials have been conducted for some glycoprotein subunit ...
