In 2009, the world saw the first influenza pandemic in more than forty years in the form of the H1N1 strain. Although response to this variant was fast and a vaccine quickly developed, the fight against influenza hasn’t ended. Bailey Willett ’20 continues to be a part of this fight as a Cornell undergraduate researcher working to combat the new strains of influenza that appear every year. Willett works alongside graduate student David Buchholz in the Aguilar-Carreno Lab of Microbiology and Immunology doing research concerning antigenic drift, one of influenza’s greatest hidden weapons. According to the Centers for Disease Control, antigenic drift is an abrupt change in the glycoprotein receptor makeup of the virus.
