Recent vaccine developments are focusing on improved efficacy and responses to emerging variants. Research led by the Oxford Vaccine Group demonstrated that the ChAdOx1 nCoV-19 vaccine reduces disease severity in vaccinated individuals compared to those unvaccinated, confirming its effectiveness against COVID-19 [1]. 

Additionally, mRNA technology continues to be a priority, with the UK government partnering with Moderna to enhance domestic mRNA research and manufacturing [2]. Projects like the Biden administration's Project Next Gen aim to create next-generation RNA platforms to improve vaccine durability and effectiveness against new variants [3][4]. Overall, advancements in both traditional and novel vaccine technologies are essential for future pandemic preparedness.
