South Africa hopes to obtain doses of Covid-19 vaccines as early as next month, but this will depend on the success of ongoing negotiations with pharmaceutical companies, according to the country’s health minister. The government is aiming to vaccinate a minimum of 67% of the population – approximately 40.3 million citizens – by the end of the year. Health Minister Zweli Mkhize said the government had so far secured enough doses to immunise 10% of the population.
