Thank you, Stephen, and good day to everyone. I will first start with a review of sales in the quarter. On Slide 22, we summarized the composition of our sales in the first quarter. As you'll see on the chart, our sales to Europe were $0.6 billion and sales to the rest of the world were $1.3 billion. Approximately $1.8 billion of sales from previously announced APAs were delivered in the first quarter of 2023, representing the vast majority of the $2 billion expected in the first half of 2023. As a reminder, U.S. sales for COVID vaccines are expected to begin in the second half of 2023, with updated strain manage. Now as we turn to Slide 23, looking at the 2023 COVID deliveries, today, we are reiterating a minimum of approximately $5 billion in COVID vaccine deliveries from current advanced purchase agreements. And we continue to expect additional orders from key markets. Of the $5 billion in 2023 deliveries from previously announced APAs, $2 billion, as I mentioned earlier, are expected to be delivered in the first half of 2023. We have already delivered $1.8 billion of that $2 billion in the first quarter with substantial fulfillment to Japan and the European Union. We expect to deliver the remaining approximately $3 billion in previously announced APAs in the second half of this year. Additionally, we expect new sales in the U.S., Japan, European Union, Asia and Latin America. I'm happy to announce that the commercial team has signed a contract with the Australian Government for 2023. Our discussion with commercial buyers in the U.S. are positive, and I will elaborate on that shortly. In our discussions with commercial customers in the U.S., it is clear that our customers are aware that COVID is still a substantial health urban. Throughout 2022, COVID continued to be a leading cause of hospitalizations. Data available through September 2022, list COVID as the third leading cost of death in the U.S. only after heart disease and cancer, as shown in the first chart on the left. The chart on the right-hand side of the slide shows the most recent data available for U.S. hospitalizations for COVID, flu and RSV. As you'll see, with current season hospitalizations of over 600,000 per COVID, the hospitalization rate for COVID is almost triple that of flu as well as more than triple that of RSV. There continues to be a clear need to protect against severe COVID infections and our customers recognize that need. For full of 2023, we expect the U.S. market volume to be approximately 100 million doses. As we highlighted earlier in the year, the successful transition of our U.S. COVID business from a government driven to a commercial-driven model is critical. We have made great progress on this front, executing on our action plan to rapidly develop this commercial market. Importantly, the commercial team is in active discussions with customers throughout the U.S. We are contracting with national and regional pharmacies, integrated delivery networks, government health providers, including the VA, the CDC and the Department of Defense, for purchasing, organizations and other providers. In addition, our established national distribution infrastructure and our Moderna Direct e-commerce site is fully operational. Our global supply chain is in place to handle all U.S. customer needs including prefilled syringes and single-dose files at the time of launch. I'm excited to share some of the launch preparation activities for the updated COVID-19 vaccine for fall vaccination campaigns. We believe these activities will drive consumers to get vaccinated. First, we are taking an omnichannel approach via tailored digital messaging to healthcare providers. This multifaceted approach will allow us to drive broad awareness and continue to emphasize the ongoing need for COVID production. Later this year, we will be disseminating customized content to drive physician demand across immunizing physicians, institutional decision-makers, as well as influencers. We are also partnering with our customer base across the different commercial segments to assist with their fall immunization programs. We believe there's an opportunity to continue to provide education, both to staff as well as to patients. And we believe there is an opportunity to harmonize and simplify the vaccination process for patients who are going in to skip their flu vaccine. Consumer promotion will be focused primarily in the fall of this year, driving patients to seek Moderna's COVID vaccine through significant DTC efforts. As I mentioned earlier, we are looking to simplify the experience for our consumers who are already going in together seasonal influenza vaccine this fall. We are energized for this fall season. Moving on to Slide 27, I will update you on our second near-term commercial opportunity, which is RSV. We are excited for the expected 2024 launch of our RSV vaccine and the commercial team is undertaking a number of activities to ensure that we develop what we hope will be a large share of that market as quickly as possible. We are already raising awareness of the health and economic burden of RSV by generating and presenting detailed data from our Phase 3 study at major medical meetings. Our medical team has shared additional data showing that vaccine efficacy is consistently high across all tested age groups as well as in participants with preexisting comorbidities. The figures on the right-hand side of the slide, detail efficacy data in these important subgroups, as we share these data at medical congresses, we are encouraged by and key opinion leader feedback on our data and the application of our mRNA platform to prevent RSV. We're engaging with payers and ITAC to ensure access upon launch. And the commercial team is active in local markets preparing for a commercial launch in 2024. Specifically, we are building our digital capabilities so that we will be able to efficiently educate customers as soon as the vaccine is approved. And as we invest in prelaunch activities, we have already begun manufacturing components of the vaccine and prefilled syringes. We are excited about the profile of the products we will be launching into these large respiratory markets. As we discussed at Vaccines Day, the estimated total addressable markets for our three key respiratory vaccines are substantial. With COVID, RSV and flu offering potential addressable markets of $15 billion, $6 billion to $8 billion and $6 billion to $9 billion, respectively. We believe we can take a sizable share of this roughly $30 billion respiratory market. The commercial team is well underway in preparing for RSV and flu launches in 2024. We believe our opportunity in the respiratory market will continue to expand beyond 2024 with our next-gen vaccines and importantly, with future combination vaccines, positioning us to drive share over time. Now on to Slide 29, I want to share with you how the commercial team is helping identify eligible patient populations in the adjuvant and neoadjuvant settings for various tumor types. Along with our partner, Merck, we have already announced that we will start Phase 3 trials in Adjuvant melanoma and adjuvant non-small cell lung cancer. There is an annual population of over 130,000 new patients in the U.S. and Europe in these two indications. Patient populations for additional potential adjuvant and neoadjuvant tumor types are listed on the right-hand side. Our commercial teams are working closely with our clinical teams to identify the largest unmet need for addressable tumor types for individualized neoantigen therapy. We are excited to be launching into a space where we have one medicine for one patient in areas of great in cancer. Given the individualized approach, we are reimagining our commercial model, along with our partner, along with patient care journey, end-to-end. With that, I will turn it over to Jamie.
