To be effective, vaccine formulas need to cover all emergent strains. But there are still plenty of unknowns.
Manufacturing is just one part of the vaccine ecosystem. It’s the health system that delivers vaccines and people must be willing to take them.
The need of the moment is for low- and middle-income countries to improve their own manufacturing capabilities.
Afrigen will be a technology transfer and training hub: it shares technology and develops skills specifically around how to produce a safe, effective and affordable mRNA vaccine.
Continuous growth of energy production and consumption, even from low carbon energy sources, could create more problems than solutions.
The creation of a Research Excellence Barometer for Africa would contribute to retaining talent and expertise and ensure that Africans benefited from their own research efforts.
This challenges the current assumption that coughing is the primary driver of TB transmission.
For the first time, the drug substance, or active ingredient for a COVID-19 vaccine - in this case mRNA - will be manufactured on the continent.
New technologies can help reduce the cost of producing maps that warn where floods might happen.
Pre-COVID-19 dentists wore some sort of respiratory protection like examination masks, surgical masks or respirators. COVID-19 has elevated the number of personal protective equipment needed.
To achieve malaria elimination on the continent, Africans need to own the agenda.
The successful development of an effective vaccine against the deadliest form of malaria that is most common in sub-Saharan Africa is indeed a major achievement.
The WHO and the manufacturers of the vaccine will be rallying countries, particularly those with high malaria burdens, to adopt the vaccine.
Smallholder rice farmers in Ghana should be supported by the government to access finance needed to adopt modern technologies for greater productivity.
Making vaccines in South Africa by building on the foundation that’s been laid is possible. But only if substantial and sustained investment in human resources and infrastructure becomes a reality.
Sexually transmitted infections and bacterial vaginosis can provide ideal conditions for HIV infection in women. A new test aims to detect these conditions even when women don’t show symptoms.
Current approaches to expand renewable energy in Ghana are not inclusive of the rural poor.
Malaria control must move away from relying too much on insecticides to more innovative and sustainable options. Genetic programming of mosquitoes is one.
Potential benefits of human genome editing include new ways to diagnose, treat and prevent genetic disorders. But there’s a significant gap in regulation.
