Thank you, Erika, and thank you, everyone, for joining us. I'm pleased to be with you today along with the members of our executive team to reflect on our fourth quarter and full year 2023 financial results and operating highlights and to discuss our priorities for 2024. In 2023, we made significant progress in our priorities, strengthening our foundation and helping to position us for success in 2024 and beyond. Throughout the year, we kept you updated on the progress we were making against our three priorities, which were, number one, deliver an updated product for the fall vaccination season. Number two, reduce our rate of spend, manage our cash flow, and evolve our scale and structure. And finally, number three, leverage our technology platform, our capabilities, and our assets to drive additional value beyond new Nuvaxovid alone. So let's take a look back at 2023 and what we were able to accomplish in these three key areas of focus for Novavax. Under priority one, deliver our updated vaccine for the fall season. All of us at Novavax are very proud that this fall we delivered on this priority. And in the face of a COVID market that was smaller than we and many others had projected, we were able to achieve $1 billion of revenue for the full year 2023, including fourth quarter total revenue of $291 million. Despite this success, we also had some misses and were disappointed in our U.S. market performance last season. Last season was a transitional season and the first fully commercial one for us in the U.S. market, and we intend to make improvements in key areas for 2024. Later on in our presentation, John Trizzino will discuss this topic in more detail. Priority number two, reduce our rate of spend, manage our cash flow, and evolve our scale and structure. 2023 was a pivotal year for the COVID market and for Novavax, as it was the first year post-pandemic and represented the first chapter in our new journey as a company post-pandemic. A key priority for Novavax in 2023 was to scale the organization appropriately and reduce our spend to better align with the evolving market opportunity. To that end, we took decisive action to reduce our expenses and our scale. We entered 2023 with approximately $2.5 billion in current liabilities and over the course of the year reduced that figure by over $800 million. And with the resolution of the Gavi arbitration, this number should be reduced further by another $500 million. In addition, we reduced our total operating expenses by over $1.1 billion in 2023, almost $150 million ahead of our stated target. And finally, under priority three, leveraging our technology platform, our capabilities and our assets, to drive additional value beyond Nuvaxovid alone. During 2023, we were able to outline a faster path forward for our flu/COVID combination vaccine program with a potential launch as soon as 2026. We are still on track to initiate a Phase 3 study this fall, and last week the FDA confirmed the data requirements to achieve accelerated approval. Dr. Filip Dubovsky will provide details later on the call on this matter. So, looking ahead to 2024 and beyond, I would like to say with 2023 now behind us, we intend to build upon our successes, learn from our disappointments and drive towards a successful 2024. In this second chapter of our new journey post-pandemic, over the next two seasons, our focus will be on share growth in the COVID market, further streamlining our business model and preparing the market for a successful launch of our combination vaccine, which we anticipate in 2026. When achieved, the launch of our combination vaccine will mark our third and potentially most exciting chapter yet post-pandemic, allowing us to expand beyond a one product company. When combined with the potential both organic and inorganic product expansion, this further supports our vision of becoming a leading global vaccine innovator. Filip will give an update on our combination program shortly through the course of this presentation. Before handing it over to the rest of the management team, I want to outline our three main priorities for 2024. So please turn to Slide 5. Our first priority is to deliver an updated product for the 2024-2025 fall vaccination season with a more competitive presentation, broader retail availability and early availability in the market with the goal of capturing increased share. Our second priority is to independently launch the Phase 3 trial of our COVID-flu combination vaccine product and showcase more of what our scientific platform is capable of through the generation and sharing of new clinical data. Finally, our third priority is to continue the evolution of Novavax with our eyes firmly on the future opportunity, further reducing our operating expenses and enhancing our processes, and while maintaining our capabilities so we can deliver on our intended business objectives. We are excited about the prospects ahead of us as we enter the second chapter of our post-pandemic journey. Our base plans, should we succeed in executing them in 2024 and 2025, promise to place Novavax in a stronger, leaner position, ready to launch our new combination vaccine and accelerate the company towards profitability and significant growth potential. Now I would like to hand it over to additional members of the team to discuss our results from the quarter in more detail, beginning with John Trizzino for our commercial updates. John?
