An-Najah News - The UK vaccines chief said that the first wave of COVID-19 vaccines are unlikely to end the pandemic.

Kate Bingham, who heads the Vaccine Taskforce, said uncertainties remain over how much protection they give and for how long.

Bingham added they should show whether the vaccines stop the virus spreading or just alleviate symptoms.

The reason we've gone for a range of vaccines is to maximise our chances that we will have at least one successful vaccine that works in the population who are most vulnerable.

"We are always looking for additional vaccines for delivery at different times or with a different immune profile."

But Ms Bingham said even a vaccine that reduces the severity of disease in vulnerable patients would still be worthwhile "a partially effective vaccine is better than no vaccine at all".
