According to Health Department spokesperson Foster Mohale healthcare workers awaiting their booster Covid-19 vaccines needn’t fear mixing and matching of vaccines (as happened in the US) due to “consistency purposes”. – The Citizen (4 Nov 2021).

South African Medical Association president, Dr Angelique Coetzee, said international studies had confirmed the efficacy of the Covid vaccine started waning after six to eight months, which meant doctors and healthcare workers needed to be given a booster shot. She said while they were not sure when the fourth wave would come, studies have shown that booster shots were needed to reduce deaths and hospital admissions. The booster is only for those who received their first dose under the Sisonke trial. The rest of the country will get it a few months later because they are not yet over their six to eight months period.
