A universal flu shot may be on the horizon.
Researchers at the University of Pennsylvania believe they have created a one-time vaccine that can fight 20 strains of influenza and remain effective for the patient’s lifetime. The school announced last week.
Dr. Scott Hensley and his team have created a ‘multivalent’ vaccine to establish immunity against all known influenza strains, but it is not intended to replace the annual flu vaccination. explained the researchers their published papersWhile annual vaccinations are tailored to combat the strongest strains of that year, university vaccinations are aimed at combating the next major influenza pandemic.
“The idea here is to develop vaccines that give people a baseline level of immunological memory against different strains of influenza, so that when the next flu pandemic hits, they will get much less sick and die. will be,” Hensley said in a statement.
of Estimation of CDC Influenza is responsible for 52,000 deaths annually between 2010 and 2020.
The researchers created the shot using the same technique used by Pfizer and Moderna to make the COVID-19 jab. A universal influenza vaccine would induce a “memory immune response that can be quickly recalled and adapted to new pandemic virus strains” rather than providing a “bactericidal” effect in individuals.
Hensley and his team found that they were able to successfully test jabs in mice, even when the animals were exposed to a strain of influenza different from that used in the injection.
The team plans to test this universal vaccine in humans in the near future.
Vaccines are designed for people of all ages, but Hensley told the Philadelphia Inquirer It is believed to be most effective when administered to children.
“If the vaccine is administered early in childhood, it may offer the first blessing of induced immunity,” Hensley said.
