Influenza Viruses

Vaccination reduced influenza-related hospitalizations by around one-third in the Southern Hemisphere this year, according to interim data published Thursday by the CDC.

HHS announced that it will give Moderna around $176 million to accelerate the development of a messenger RNA-based pandemic influenza vaccine amid an ongoing outbreak of avian influenza.

A novel combination of neuraminidase mutations detected in influenza A(H1N1)pdm09 viruses on several continents has left these viruses less susceptible to treatment with oseltamivir, researchers found.

Moderna announced positive phase 3 trial data for its combination COVID-19 and influenza vaccine this week, suggesting a combination shot for respiratory infections is on the way.

Moderna announced positive interim results from a phase 3 trial of its next-generation COVID-19 vaccine, which the company said will help pave the way for its combination shot against COVID-19 and influenza.

Similar to SARS-CoV-2, which can cause long COVID, people hospitalized with influenza are at an increased risk for health issues long after they have cleared the infection, according to a study.

BOSTON — Expanded use of wastewater surveillance confirmed spikes in clinical cases of COVID-19, influenza and respiratory syncytial virus in one of Canada’s largest cities, according to study findings presented at IDWeek.

Moderna said Wednesday that its messenger RNA-based combination vaccine against influenza and COVID-19 elicited neutralizing antibody levels that were as high — or higher — than existing vaccines in a phase 1/2 trial.

LISBON, Portugal — The risk for death from COVID-19 is three to four times higher than it is from influenza among hospitalized patients requiring oxygen therapy, researchers found.

A new study reinforced that influenza vaccination protects children from serious illness even when vaccines are a poor match for circulating viruses.
