A British study that found people who have had COVID-19 are unlikely to contract the disease again for at least six months is good news and also provides hope for vaccines, a senior official from the World Health Organization (WHO) said Friday.
"This is really good news to see that we are seeing sustained levels of immune responses in humans so far," Mike Ryan, the WHO's top emergency expert, told a news conference. "It also gives us hope on the vaccine side."
Maria van Kerkhove, the WHO's technical lead on COVID-19, said: "We still need to follow these individuals for a longer period of time to see how long immunity lasts." (Reuters)
