Thanks, Stéphane, and hello, everyone. Today, I will walk you through our financial performance for the first quarter and provide commentary on our 2024 financial framework. Let me start with our commercial performance on Slide 8. Net product sales for Q1 were $167 million, down 91% year-over-year, mainly driven by lower sales volumes of our COVID-19 vaccine in regions outside the United States. This decline aligns with the anticipated transition of the COVID-19 vaccine market or it's a seasonal pattern, whereas in the first quarter of 2023, we primarily delivered doses that were deferred from 2022. Q1 was driven by sales in the U.S. and the Rest of the World, largely Latin America markets. For Q2, we expect about $100 million in sales for a total of approximately $300 million in the first half of 2024. Q2 will include a portion of our recently announced contract with Brazil. Moving to Slide 9. Net product sales were $167 million, as I just explained. For the first quarter of 2024, our cost of sales was $96 million, which included third-party royalties of $8 million, inventory write-downs of $30 million and $27 million related to unutilized manufacturing capacity and wind out costs. This resulted in our cost of sales representing 58% of net product sales, up from 43% in the same quarter last year. The increase in cost of sales percentage was primarily due to the lowest level of sales in the quarter. We continue to expect the full year cost of sales to be approximately 35% of product sales. However, due to the strong seasonality of our business, we expect a higher percentage in the first half. Moving to our R&D efforts. Q1 R&D expenses were $1.1 billion, reflecting a decrease of 6% year-over-year. This reduction was primarily due to the absence of upfront collaboration payments being made this quarter. The upfront payments made in the first quarter of 2023 were related to our strategic collaborations with Generation Bio and Life Edit Therapeutics. With the Q1 spend of $1.1 billion, we are tracking towards the full year expected spend of approximately $4.5 billion. Q1 SG&A expenses were $274 million, marking a 10% decrease year-over-year. Importantly, this decrease was driven by all functions in SG&A, and it is a result of our strong focus on cost discipline and strategic investments, driving productivity. I will provide additional color on the next page. We reported an income tax expense of $10 million for the first quarter of 2024 compared to an income tax benefit of $384 million in the same period last year. The shift is primarily due to the continued application of valuation allowance on the majority of our deferred tax assets, which we first established in the third quarter of 2023. Net loss for the period was $1.2 billion compared to net income of $79 million last year. Diluted loss per share was $3.07 compared to diluted earnings per share of $0.19 in 2023. We ended the first quarter with cash and investments totaling $12.2 billion, down from $13.3 billion at year-end 2023, largely attributable to research and development expenses and operating activities. Moving to Slide 10. I want to take a moment to elaborate on the efficiencies we are now seeing across the company. As a platform company, we have the opportunity to build a unique operating model. And over the last few years, we have invested purposefully into people, processes and technologies to build foundational capabilities that will allow us to scale efficiently. First, we ended 2023 with nearly 6,000 employees, up from 1,300 at the end of 2020. Every function scaled capabilities to enable the increasing product launches we expect over the coming years. Additionally, as you know, Moderna has always led with a digital-first mindset. Over the past 3 years, we have nearly doubled our built-for-purpose software applications to digitally enable our teams. As an example, we recently went live with the newly implemented rebuilt ERP system. SAP S4/Hana is our new digital backbone for all our operational activities. We have used SAP in the past, however, it was built for a research and development-focused company. And now we have implemented an entirely revised version, supporting our end-to-end business processes more effectively and efficiently. Another example is our rapid adoption of artificial intelligence. Over the past year, we have built over 750 GPTs. One example in the legal space, our contract companion GPT streamlines the task of reviewing and summarizing contracts across the business. With the GPT providing step-by-step guidance to craft a tailored and insightful salary. This enables any function to extract critical insights on contracts whenever needed, minimizing bottlenecks and freeing up Moderna's legal department to focus on work of higher strategic value, thus enhancing operational efficiency and decision making. Another example in G&A is a big purchase of paid GPT for all questions around our procurement and payment processes. Instead of our employees having to find and read policies and procedures, they can easily query to GPT. It also saves time for our procurement and payables teams from answering numerous questions. AI has already been a good chance for win in short period of time. In general, we see the areas helping incredible speed that allows for an unprecedented impact on productivity and many more. We have rolled out a comprehensive training program and are committed to driving this technology breakthrough. 1 As a result of these strategic investments in the people, processes and technology, we were able to significantly reduce purchase services and our use of external consultants, which contributed heavily to the 10% year-over-year reduction in SG&A spend. We are also seeing similar benefits in R&D and manufacturing. In general, we now have a solid foundation with our operating model. As we continue to grow our commercial activities, we will need to further invest, however we will be able to do that more efficiently. Now let's turn to the 2024 financial framework on Slide 11, which is in line with what I shared on our last earnings call in February. We continue to expect net sales for 2024 of approximately $4 billion, which we think will be a low point as we expect to return to growth in 2025. Sales in the first half of the year are now expected to be approximately $0.3 billion. We continue to expect cost of sales of approximately 35% of product sales for the full year. For R&D we continue to expect full year expenses to be approximately $4.5 billion, down from $4.8 billion in 2023. For SG&A, we continue to expect full year expenses to be approximately $1.3 billion down from $1.5 billion in 2023, and we expect taxes to be negligible in 2024 and capital expenditures in 2024 to be approximately $0.9 billion. Finally, we expect to end 2024 with approximately $9 billion in cash after touching a low point of approximately $8 billion at the end of Q3, due to the seasonality of collections. Finally, let me also touch on our recently announced project financing deal with Blackstone, which we are excited about. In March, we entered into a development and commercialization funding arrangement, which commits Blackstone to providing us with up to $750 million of funding for our flu program, so that we can strengthen the product label and fulfill our remaining regulatory applications. Subject to the regulatory approval in the United States, which depends on data from the funded activities, Blackstone will be entitled to receive up to $750 million in sales milestone payments. These milestone payments are contingent upon achieving specified cumulative net sales targets for our future influenza and combination vaccines. Additionally, Blackstone will earn royalties on applicable net sales at a low single-digit percentage rate. This funding will offset our R&D expenses and is factored into our R&D framework for the year of approximately $4.5 billion. Overall, we are excited that this deal enables us to accelerate the advancement of our pipeline. And with that, I will now hand the call over to Stephen.
