This is Scientific American's 60-Second Science. I'm Karen Hopkin. This will just take a minute.
Some people never forget a face. Others never forget a flu. Even if they were infected more than 90 years ago. A team of American scientists studied 32 people who survived the 1918 flu epidemic1. That virus, also called the Spanish flu, killed an estimated 20 to 100 million people worldwide.
Of course many more survived, and some are still around today. The scientists tracked them down and took a small sample of their blood. And they found that all 32 people they tested still had circulating antibodies that could recognize the 1918 flu strain. What’s even more remarkable2 is that these immune molecules3 still work. Injecting the antibodies into mice protected the animals from experimental infection with the virus. The results were published online in the journal Nature on August 13th.
The scientists say that these elder antibodies could guide the way to new therapies to ward4 off flu should a virus similar to the 1918 strain arise. In the meantime, I guess you can be thankful that as your joints5 grow creaky and your vision fades, at least your immune system stays on its feet.
Thanks for the minute for Scientific American's 60-Second Science. I'm Karen Hopkin.
