WASHINGTON (Reuters) - Antibodies from survivors of the 1918 flu pandemic, the worst in human memory, still protect against the highly deadly virus, researchers reported on Sunday.
The findings by a team of influenza and immune system experts suggest new and better ways to fight viruses -- especially new pandemic strains that emerge and spread before a vaccine can be formulated.
These survivors, now aged 91 to 101, all lived through the pandemic as children.
Their immune systems still carry a memory of that virus and can produce proteins called antibodies that kill the 1918 flu strain with surprising efficiency, the researchers report in the journal Nature.
