COVID has demonstrated the importance of regulatory systems that ensure the safety and efficacy of therapeutic products as well as patient access to these products, especially in the complex network of healthcare, scientific, pharmaceutical, regulatory, and patient communities in Europe. “Regulators and industry have worked day and night over the last two years to bring vaccines and therapies forward. We know very clearly that sustainability of the system is an issue. More regulatory resources and simpler processes are desperately needed,” explains Isabelle Stoeckert, Bayer AG vice president and head of regulatory affairs for Europe, Middle East, and Africa. “Many countries have learned that reliance and collaboration between regulators is a really good thing. COVID-19 has really shown that,” suggests Henrik Nielsen, Novo Nordisk vice president of global regulatory sciences. “And I think this will stay, so we will see more reliance between regulatory sources, and we'll probably see increased use of different collaboration schemes around the world.”
