Real-World Monitoring of COVID-19 Vaccines: An Industry Expert View on the Successes, Challenges, and Future...

Pharmacovigilance leaders from major vaccine developers describe the learnings from the coronavirus disease 2019 (COVID-19) pandemic in the area of pharmacovigilance and pharmacoepidemiology. The authors aim to raise awareness of the co-operation among vaccine developers, highlight common challenges, advocate for solutions, and propose recommendations for the future in the areas of real-world safety and effectiveness, safety reporting and evaluation, and regulatory submissions. To enable timely evaluation of real-world safety and effectiveness, multi-sponsor study platforms were implemented, resulting in quicker recruitment over wide geographical areas. Future gains could be derived by developing geographically flexible, common protocols and/or joint company-sponsored studies for multiple vaccines and a collective strategy to build low/middle-income country (LMIC) sentinel sites. Safety reporting, signal detection and evaluation was particularly challenging given the unprecedented number of adverse events reported. New methods were required to manage increased report volume while maintaining the ability to quickly identify and respond to new data that could impact the benefit-risk profile of each vaccine. Worldwide health authority submissions, requests for information and differing regulatory requirements imposed significant burden on regulators and industry. Industry consensus on the safety reporting requirements and joint meetings with regulatory authorities markedly reduced this burden for all stakeholders. The most impactful innovations should be undertaken rapidly and expanded to other vaccines and therapeutics, with a multi-stakeholder approach. The authors of this paper make future recommendations and have launched an initiative named BeCOME (Beyond COVID Monitoring Excellence) with a focus on actions in each of the highlighted areas.
