Horses get the flu, too

(University of Rochester Medical Center) Flu vaccines for horses haven't been updated in more than 25 years, but researchers have developed a new live equine influenza vaccine that's safe and more protective than existing vaccines. Proactively preventing the spread of flu in animals is important, as animals are the most likely source of future human pandemics. Animals can be infected with multiple influenza viruses and have the potential to act as 'mixing vessels,' generating new strains that could infect people.
