In-depth: How a Cape Town company made an mRNA vaccine and what happens next

In January, Cape Town-based biotechnology company Afrigen Biologics announced that it has successfully produced a lab-scale batch of a mRNA vaccine against COVID-19 that is similar to that made by pharmaceutical company Moderna. Catherine Tomlinson takes an in-depth look at how Afrigen managed to reach this point and what further challenges have to be overcome before mRNA vaccines can be produced at scale in South Africa

COVID-19: Will vaccinated people in South Africa need booster shots?

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.

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.

In-depth: What will it take to actually make mRNA vaccines in SA

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.

Analysis: How do you price a life-saving vaccine during a pandemic?

In late January, Dr Anban Pillay, Deputy Director-General in South Africa’s National Department of Health, revealed that South Africa would pay more than double the price paid by the European Union (EU) for AstraZeneca’s COVID-19 vaccine. This set off a flurry of questions on how vaccine prices are set and why, in many cases, the prices themselves are not known to the public. Catherine Tomlinson takes a closer look at the issues involved.

Opinion: Pivot to J&J vaccine makes sense in light of new findings

Government deserves criticism for various aspects of its COVID-19 response, but some social media criticism following Sunday’s announcement that the Oxford University/AstraZeneca vaccine has little or no efficacy in preventing mild-to-moderate disease caused by the 501Y.V2 variant has been unfair, writes Marcus Low.

Where are we in the race for a HIV vaccine?

While progress in the race for effective COVID-19 vaccines has been rapid and impressive, an effective HIV vaccine remains elusive. As part of Spotlight’s World AIDS Day 2020 coverage, Kathryn Cleary asks two of South Africa’s top vaccine researchers to update us on where we are in the race for an HIV vaccine.
