LONDON (AP) — Warning that the first COVID-19 vaccines may be imperfect, the head of the U.K effort to develop a vaccine called Wednesday for immediate international cooperation to prevent the “largest global recession in history.’’
U.K. Vaccine Taskforce chair Kate Bingham also warned against over-optimism, saying there is no guarantee a successful vaccine against the novel coronavirus will ever be developed.
“The first generation of vaccines is likely to be imperfect, and we should be prepared that they might not prevent infection, but rather reduce symptoms, and, even then, might not work for everyone or for long,’’ Bingham wrote in an essay published in The Lancet medical journal.
No vaccine has ever been developed against any coronavirus, and numerous attempts to design vaccines against SARS and MERS, two which are related to the virus that causes COVID-19, have failed. Scientists also warn that immunity against coronaviruses appears to fade over time and that achieving any vaccine-induced immunity to protect against infection or severe disease could be challenging.
