Die Spanische Grippe kehrt zurück
Vielleicht. Mittlerweile haben Forscher immerhin die Antikörper isoliert:
The team was then able to isolate exceedingly rare B cells – the immune cells that produce antibodies – from eight of those samples and grow them in culture. Seven of those samples produced antibodies to a 1918 virus protein, suggesting that their immune systems were waiting on standby for a long-awaited second outbreak.
"The B cells have been waiting for at least 60 years – if not 90 years – for that flu to come around again," said Crowe Jr., "That's amazing…because it's the longest memory anyone's ever demonstrated."
[...] Although aging typically causes immunity to weaken, "these are some of the most potent antibodies ever isolated against a virus," Crowe said. "They're the best antibodies I've ever seen."
