H3N2 News and Research

RSS

Influenza A virus subtype H3N2 (also H3N2) is a subtype of viruses that cause influenza (flu). H3N2 viruses can infect birds and mammals. In birds, humans, and pigs, the virus has mutated into many strains. H3N2 is increasingly abundant in seasonal influenza, which kills an estimated 36,000 people in the United States each year.

New mRNA flu vaccine shows promise: Faster to produce, highly effective in mice

The study evaluates the efficacy of a new quadrivalent mRNA influenza vaccine, finding it to be highly immunogenic and protective in a mouse model. Compared to traditional vaccines, the mRNA-based option offers advantages like reduced production time and elimination of the risk of growth-promoting mutations.

How does chronic HBV infection affect flu and COVID-19 vaccine responses?

The influenza season marks the beginning of a time of illness, sometimes serious or even fatal, in much of the world. For this reason, flu shots are recommended, especially for individuals with underlying diseases such as chronic hepatitis B (CHB) infection, since they are at higher risk for adverse outcomes.
