The 1957-58 influenza pandemic, also called Asian flu was a time when many people caught H2N2 influenza A and became sick. Westerners first learned about this influenza when it was in Singapore. It killed 1.1 million people.[1]

The influenza virus that caused the pandemic had an HA antigen and NA antigen that scientists had never seen before, so they named it "H2N2."[2]

The 1957 influenza pandemic was the first time scientists truly studied how influenza could move through large groups of people who had not had vaccines that worked against it yet.[2]
