The two vaccines used in South Africa’s vaccination programme, those from Johnson & Johnson and Pfizer/BioNTech, have both been shown to be highly effective against COVID-19, particularly in preventing hospitalisation and death. But protection may wane over time and new variants may or may not render these vaccines less effective. Adele Baleta unpacks what we do and do not know about the potential need for booster shots and surveys some of the studies that will help fill the gaps.
On Monday President Cyril Ramaphosa announced that South Africa will host the first World Health Organization-backed COVID-19 mRNA vaccine Technology Transfer Hub – an initiative designed to get the production of mRNA vaccines off the ground in Africa. Parties involved in the hub expect to hear as early as next week whether pharmaceutical companies with mRNA COVID-vaccines for COVID-19 on the market – Moderna and Pfizer/BioNTech – will share their know-how with the hub.

Messenger RNA (mRNA) vaccines, such as the COVID-19 vaccines made by Moderna and Pfizer/BioNTech, have been hailed for their manufacturing advantages over conventional vaccines – so much so that African leaders such as President Cyril Ramaphosa has called for mRNA production capacity to be developed in Africa. Catherine Tomlinson examines why mRNA vaccines are easier to make than some other types of vaccines and asks what it will take to build such production capacity.
