Accra, 18 March 2021 – COVID-19 vaccination in Africa is gathering pace, with more than 7 million doses so far administered. But the continent received vaccines later than other regions of the world and in limited quantity. A few weeks after launching vaccinations, some countries are nearly exhausting their initial supplies. Professor William Ampofo, chairperson of the African Vaccine Manufacturing Initiative, discusses vaccine manufacturing in Africa.

What is the current vaccine manufacturing capacity in Africa?

There are fewer than 10 African manufacturers with vaccine production, based in five countries: Egypt, Morocco, Senegal, South Africa and Tunisia. There is very limited upstream production, with most local companies only engaging in packaging and labelling, and occasionally fill and finish steps. There are about 80 sterile injectables facilities on the continent, which may provide an opportunity for vaccine production given the primary dosage form in Africa is vials.

How does that capacity affect vaccine availability in the continent?

Almost all the current vaccine capacity in Africa is focused on supply to internal country markets with very little export taking place. Current capacities are modest with a glaring absence of large-scale (fewer than 100 million doses) capacity.

As highlighted by COVID-19, this severely limits vaccine availability in disease emergency situations as there is no immediate readiness to repurpose facilities for large-scale production through partnerships. It is therefore vitally important that African vaccine manufacturers establish supply networks to export to markets in Africa and elsewhere. Supply chain could use the existing economic zones in Africa. For example, the Economic Community of West African States.

How does Africa source vaccines and what are the challenges?

Most African countries are supplied with vaccines by UNICEF supported by Gavi, the Vaccine Alliance, with fewer than 10 countries being self-sufficient in terms of vaccine procurement. This has led to a very specific shaping of vaccine markets in Africa where more than 1.5 billion doses are supplied through UNICEF.

Consequently, this presents enormous challenges when trying to establish sustainable vaccine industries in Africa which would ideally require advance purchasing support from African governments. In the current dispensation this is simply not possible when most countries don’t buy their own vaccines and therefore cannot commit to buying locally manufactured vaccines.

What are the impediments to developing African vaccine self-sufficiency?

The biggest impediment is the way vaccine markets are structured in Africa. Without the commitment and support to buy vaccine manufactured in Africa it will forever remain a difficult challenge to build a sustainable industry capable of producing vaccine doses at scale.

This is where African governments, continental bodies such as the African Union and other stakeholders can make a difference. The current system design requires a shift and complete review to enable this desperately needed capacity to be established as shown by COVID-19 and the delays despite the best efforts of the COVAX Facility

Vaccine manufacturing is complex and requires huge financial investments and a long-term vision. It’s a long-distance race not a 100-metre dash. One must begin with the end in mind i.e. the vaccine market in Africa and the way vaccine procurement and supply currently occurs. There is a need to focus on core issues such as innovative financing, enabling local and regional regulatory capacity to assure quality, critical technical elements including skills development, technology transfer and product development partnerships, Good Manufacturing Practice facility design and establishment.

How can vaccine development and manufacturing be scaled up?

What must be appreciated from the start is that when it comes to setting up vaccine production capability at scale to meet current global quality standards, the whole is greater than the sum of the parts. We cannot simply look at the different pieces separately or in boxes and think that we can approach this in a linear fashion. 

The capability to produce vaccines requires a fully integrated approach, pulling together elements mentioned earlier (finance, skills development, regulatory, facilities, technology know-how, etc).

It might be useful to think of this as coin with two sides. On one hand are what one might consider to be technical issues: facilities, quality systems, skills development etc. On the other the issues of finance, the vaccine market and procurement channels are most critical. 

So, for Africa, focusing specifically on the technical aspects, what might work best is to establish what is called fill/finish capacity - otherwise referred to as drug product manufacture - first. This would allow for collaboration with multiple partners for multiple products using a single formulation/filling line.

Then in a phased approach, step back-up the vaccine manufacturing value chain and install capacity to produce drug substance, antigen or active pharmaceutical ingredients. This approach manages the investment risk upfront and builds vaccine manufacturing know-how in a manageable way. 

The current COVID-19 pandemic presents a great opportunity to harness the various conversations and proposals into an action oriented road map led by the African Union and regional bodies that will lead to increased vaccine production in Africa to facilitate immunization of childhood diseases and control outbreaks of highly infectious pathogens.
