'Killer' cells in Ebola immunity study could help Covid research

Immunity from the deadly Ebola virus could last years after the infection, the world’s longest study of survivors by British and Guinean scientists has concluded in findings that could have implications for Covid immunity research.

The findings are the result of the world’s longest and most comprehensive study of survivors from the devastating west African outbreak between 2013 and 2016. They could help the understanding of the body’s immune response to Covid and other zoonotic diseases.

A recent study suggested antibodies for Covid may only last two months, leading to speculation that immunity to the virus may not be long-lived and those who have recovered would be at risk of reinfection.

The team of scientists in Guinea found that some Ebola survivors there showed no antibodies three months after the infection even though they would have to mount a strong response to fight such a lethal virus.
