Nearly two years after Covid-19 was first detected in Wuhan, the world is still very much in a pandemic. The toughest phase may behind us, but we are still faced with the possibility of new variants of concern, waning immunity and vaccine evasion. As first-generation vaccines start to show their weaknesses, next-generation vaccines are becoming more and more important. While hundreds of vaccines are in the pipeline, there are a few frontrunners and other interesting candidates that might be meaningful additions to our Covid vaccine armamentarium. Experts discuss the current status of a number of protein-based vaccines including candidates from Novavax, Vaxine, Clover, GSK/Sanofi and others. DNA vaccines are also still an attraction with the first authorization for Zydus Cadila in India. Other mRNA vaccines might offer meaningful differentiation, while vaccines targeting the S and N protein might also have greater importance when it comes to tackling future variants. While nasal and oral vaccines seem appealing for the prevention of infection and transmission, they also have some inevitable hurdles to overcome and are still a long way off materializing. Experts discuss future manufacturing hurdles that will require greater global collaboration to achieve future vaccine production and distribution goals. Finally, experts discuss the current global status so far and forecasts for exiting the pandemic state and entering a livable endemic.
