WHO GENEVA : VACCINE SOLUTIONS VECTORS

WHO says researchers working on more than 200 vaccine candidates around the world.

The World Health Organization said Thursday that a few hundred million Covid-19 vaccine doses could be produced by the end of year and be targeted at those most vulnerable to the virus.

The UN health agency said it was working on that assumption, with a view to two billion doses by the end of 2021, as pharmaceutical firms rush to find a vaccine.

WHO chief scientist Soumya Swaminathan said researchers were working on more than 200 vaccine candidates around the world, including 10 that are in human testing.

''If we're very lucky, there will be one or two successful candidates before the end of this year,'' she told a virtual press conference.

She identified three groups most in need of the first vaccine doses.

They are front-line workers with high exposure, such as medics and police officers, those most vulnerable to the disease, such as the elderly and diabetics; and people in high transmission settings, such as urban slums and care homes.

''You have to start with the most vulnerable and then progressively vaccinate more people,'' Swaminathan said.

''We are working on the assumption that we may have a couple hundred million doses at the end of this year, very optimistically,'' she said.

''We're hoping that in 2021 we will have two billion doses of one, two or three effective vaccines to be distributed around the world. But there's a big 'If' there, because we don't yet have any vaccine that's proven.

''But because of all the investments going into this, let's say we have two billion doses by the end of 2021, we should be able to vaccinate at least these priority populations,'' [AFP]
