High-income countries are claiming a lion’s share of the first available batches of the COVID-19 vaccine in total disregard of the consequences such approach would have on the low-income countries that lack both the manufacturing wherewithal and the financial resources to purchase the vaccine and other products needed to combat the pandemic. This paper reviews the existing TRIPS Flexibilities and analyses their limitations with respect to equitable access of pharmaceutical products in times of health emergencies. This paper then considers the unique challenges that have been brought to the fore by the COVID-19 pandemic. Finally, this paper analytically explores some options that have been proposed so far that the World Trade Organization (WTO) or governments can take in the immediate to near term to facilitate equitable access to COVID-19 pharmaceutical products and technologies. This research is non-empirical, desk-based research. It is, therefore, based on the literature review of existing body of work that is relevant to the topic under discussion. Mindful of the epistemological challenges that are always associated with desk-based research, part of the methodology of this work is to seek support from related empirical studies based on different philosophical underpinnings but that confirm the working hypothesis of this research.\u0000\u0000\u0000Findings\u0000This paper finds that there is still a need for a comprehensive reform of TRIPS Agreement to streamline the voluntary licencing system which is an important tool for low-income countries’ access to affordable pharmaceuticals.

Its goal of voluntary convergence is portrayed as standardisation rather than as absolute congruence.

This is evidenced by provisions in African regional investment instruments such as the 2007 Common Market of Eastern and Southern Africa Investment Agreement and the 2008 Economic Community of West African States Supplementary Act on Investments produced by the different African regional economic communities (RECs), new-generation IIAs such as the 2016 Nigeria-Morocco IIA and the China-Tanzania IIA and the African Union’s Pan-African Investment Code 2016. The common features of these instruments include linking the objective of investment promotion and protection to sustainable development; excluding portfolio investments; including provisions on investor-obligations; and reserving wide scope of regulatory space for host-states, including the ability to take emergency measures without incurring liability to investors. Some of these provisions are rare in IIAs.\u0000\u0000\u0000Findings\u0000The study finds that, while the efforts are commendable, there are real challenges. Firstly, there are inconsistencies in the regimes existing on the continent due to differences in the contents of the international investment instruments promulgated by the different RECs, and also differences in the content of IIAs signed by some member-states of the RECs with countries external to the RECs. Secondly, there are governance gaps and a lack of enforcement in practice, which would undermine the effectiveness of the laws being forged. Thirdly, the Africanised IIL alone would not attract investment if other important determinants, such as critical infrastructure, remain lacking. Fourthly, there is under-representation of Africa in the arbitral institutions that develop and enrich the laws, which, if it continues, would undermine the effectiveness of the Africanisation provisions being included in IIAs.\u0000\u0000\u0000Research limitations/implications\u0000While the research discusses both law and policy, more is discussed of the law, owing to space limitation.\u0000\u0000\u0000Practical implications\u0000It is anticipated that this research will impact the content of the investment protocol under the African continental free trade area and beyond and will prompt review of existing and future IIAs by member states of the various RECs to align them for consistency.
