Health Minister Dr Zweli Mkhize has told Parliament that Johnson and Johnson is refusing to sign off the supply of a further 20 million doses of the Covid -19 vaccine. The pharmaceutical giant first wants a letter from the Department of Trade and Industry endorsing the local investment it has made in Aspen. Mkhize says this is a surprise move as such support is already part of the agreement and has been publicly stated. He says this is only one of the many hurdles they have had to deal with as they try to secure vaccines for the country.
