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.

Novel triple assortments of swine influenza virus detected in pigs by active surveillance analysis in China

Researchers discuss the results of an active surveillance analysis for the swine influenza virus.

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.

Omicron has higher risk of in-hospital mortality compared to influenza

In a recent study published in the journal JAMA Network Open, researchers compared the hospital outcomes of patients infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant with those of influenza patients in Switzerland, assess the current disease burden due to coronavirus disease 2019 (COVID-19).

Hemagglutinin stem immunogens may hold the key for broad protection against influenza A viruses

Researchers proposed that vaccines targeting the immunosubdominant yet conserved hemagglutinin (HA) stem could trigger broadly neutralizing antibodies (bnAbs) against influenza A viruses.

Skipping methotrexate for one week after flu vaccine provides the same seroprotection as a two-week hold in RA patients

New research presented this week at ACR Convergence 2022, the American College of Rheumatology's annual meeting, showed that discontinuing methotrexate for one week after seasonal influenza vaccination provided the same seroprotection as a two-week discontinuation period in patients with rheumatoid arthritis.
