All of the flu shots for the 2024-2025 season are trivalent, meaning they protect against three different flu viruses. The new shots will include two influenza A viruses (H1N1 and H3N2) and one influenza B virus, per the CDC. “We include different strains because more than one strain is ...
"There has been another strain in Canada that caused really severe disease in a teenager who ended up in critical condition in the hospital," Dr. Meghan Davis, an associate professor of environmental health and engineering at Johns Hopkins Bloomberg School of Public Health, told ABC...
The first person confirmed to have contracted the Bird Flu from cattle was in Texas back in March. This was the first instance globally of a confirmed diagnosis in humans. Canva The CDC has been tracking a strain of Bird Flu since 2020 that has been spreading in more and more animals spec...

to be contagious between humans, and it is not certain to evolve in that direction, but the disease is clearly changing. The current strain of H5N1 has been spreading to animals that have never been affected before, and pets that can pass it to people could play a role in how it ...
Tests showed that the strain that caused the person’s illness is one found in wild birds, but not in cattle. Last month, health officials in Canadareportedthat a teen in British Columbia was hospitalized with a severe case of bird flu, also with the virus strain found in wild birds. ...
People also have benefited from mutation trends in COVID, which have tended to favor the Omicron strain and its descendants, Schaffner said. “Those viruses appear to be somewhat less severe in their presentations,” he pointed out. But Lovins and Schaffner stressed that people should n...

strain selection. Experts select strains based on experimental measurements of antigenic drift and predictions made by models from hemagglutinin sequences. We developed a novel influenza forecasting framework that integrates phenotypic measures of antigenic drift and functional constraint with previously ...
