500,000 health workers should be vaccinated against COVID-19 by Saturday. That’s according to the Sisonke programme co-lead. Just over 400,000 have received the jab so far, with the doses for the Sisonke trial expected to be finished by the weekend. The programme says a number of factors slowed the vaccination process, but government's rollout to the public will be on a much bigger scale. Courtesy #DStv403
