2 Ebola vaccines show immune response for a year

Two shots that protect against Ebola virus yielded immune responses lasting for at least a year, according to a study suggesting they might keep the virus at bay for the long-term.

Researchers studied the vaccines, one from Merck & Co. and a two-dose regimen from Johnson & Johnson and Bavarian Nordic A/S, in 1400 adults and 1401 children enrolled from April to December 2018, according to a report from the Partnership for Research on Ebola Vaccinations research consortium.

People responded to the shots within two weeks of receiving them, and the highest rate of response was achieved by the Merck vaccine plus a booster, according to the study published Wednesday in the New England Journal of Medicine.

Ebola has been a thorn in the side of health officials as it continues to emerge unpredictably in African countries.

The World Health Organization is working with Uganda to fight a vaccine-resistant Ebola strain called Sudan that’s caused more than 140 confirmed cases and 55 deaths there.
