Thank you, Jamey. Today, I'll review updates from our clinical programs that were shared during our recent Vaccines Day, as well as new developments in our therapeutics portfolio.
Starting with respiratory vaccines. We shared updates to many of our respiratory programs at Vaccines Day in March. Our RSV vaccine in Canada is undergoing regulatory review in multiple countries. And pending approval, we expect to launch the product in the United States following the June ACIP meeting and recommendations this year.
At Vaccines Day, we shared updates from co-administration studies of RSV, confirming the ability to administer our vaccine and other vaccines given during the respiratory season.
With our flu program, we recently presented data from our Phase III P303 study at ECCMID and continued discussions with regulators globally towards the goal of filing this year. For our next-generation COVID vaccine, mRNA-1283, we have presented positive Phase III safety and immunogenicity data and are engaging with regulators on the path to approval for that product. Our combination flu and COVID vaccine, mRNA-1083 is in Phase III, and we look forward to sharing those clinical data in the current quarter.
Turning now to our leading and other vaccines. As shared at Vaccines Day, we've had -- we've made significant progress in this portfolio. Our CMV vaccine, mRNA-1647, has fully enrolled its Phase III trial, and we have the potential for an interim analysis of efficacy this year. We announced positive Phase I immunogenicity and safety data from our EBV vaccine candidate, mRNA-1189, and we are now advancing towards pivotal trials with that program.
A second therapeutic EBV candidate, mRNA-1195 is in a separate ongoing Phase I study. mRNA-1468, our vaccine against varicella-zoster virus showed strong immunogenicity, including strong T cell responses, and we are preparing to move that program forward towards a pivotal Phase III study as well.
And our HSV vaccine against Herpes simplex mRNA-1608, is now fully enrolled in its Phase I/II study, and we look forward to sharing clinical data updates when that's available. Now rounding out this portfolio, we presented the positive clinical data from our norovirus vaccine candidate, mRNA-1403 and shared that we are advancing that program towards its pivotal Phase III trial.
Turning now to Oncology Therapeutics. We are happy to report our ongoing Phase III studies are enrolling well. We were excited to announce 3 new INT trials, including a randomized Phase II/III study in neoadjuvant, adjuvant cutaneous squamous cell carcinoma; a randomized Phase II trial in adjuvant high-risk muscle invasive bladder cancer; and lastly, a randomized Phase II trial in an adjuvant renal cell carcinoma.
Now recently at AACR, we presented Phase I data from our INT program in advanced unresectable HPV-negative head and neck cancer in the metastatic setting. At AACR, we also presented Phase I translational data from another oncology therapeutic program, mRNA-2752 in various tumor types. Links to both of these presentations are provided on the slide.
Now as a final note, at ASCO, we'll be hosting another Moderna oncology event on the evening of June 3, and we look forward to seeing you there or having you join us virtually.
With that, I'll turn it back over to Stéphane.
Stéphane Bancel: Thank you, Stephen and Jamey. Slide 18 is an overview of our COVID-19 strategy for 2024, which is focused on the need of each 2 region.
In the U.S., our focus is working with public health officials, health care providers and pharmacies to increase vaccination coverage rates. In Europe, we are actively participating in the 2024 tender process. The tender allows for up to 36 million doses per year for up to 4 years. And in the Rest of the World, we have reoriented our commercial teams to prioritize markets for greater commercial focus and impact.
As mentioned earlier, the Brazil contract is an example of how this is working. In the fall of 2023, U.S. COVID vaccination rates lagged behind flu-vaccination rates. U.S. COVID vaccination rates were 11%, with flu vaccination rates at 4x that. And yes, COVID continues to show a higher [indiscernible] dieses.
U.S. operation for COVID began October 2023. And last week, we have 424,000 people, which is markedly higher demonstration from either flu or RSV infection. Actually, COVID operations were around the same level as [indiscernible] of flu plus RSV combined.
In addition, long COVID continues to be a serious risk to many healthy young adults in their 20s, their 30s, their 40s are losing lung capacity and the mental capacity due to long COVID. The data shows that COVID-19 vaccine reduced the risk of long COVID by 70%.
We believe education and awareness will be very important. We are working on educating consumers about the need for an annual COVID vaccine, just like flu. Too many people are getting hurt when we have safe and effective vaccines available. Our job will not stop until these vaccination numbers come down significantly.
As you know, strength selection by health authorities received approval and launch of COVID vaccine. Health authorities including the WHO and EMA in Europe, have recently selected the JN.1 strain for the 2024-25 formula. The FDA will launch the [ real fast ] meeting on May 16 to select the strength for the U.S. market.
Moderna has already manufactured JN.1 drug substance to support the potential August launch. We have also prepared for backups in case the FDA does not select JN.1. In 2023, COVID vaccines were available 5 weeks later after 2 vaccines. In the recent channel alone, more than 3 million flu vaccines were administered before the updated COVID vaccines were available.
As we look into the fall 2024 season, we see the potential to align the timing of flu and COVID vaccine approvals. We are encouraged by the earlier [indiscernible] meeting for this year's COVID trend selection versus last year. And we're working here and [indiscernible] for timely COVID approval. We expect higher vaccination uptake if COVID vaccines are available sooner.
Turning now to the anticipated launch of our second respiratory vaccine, or RSV vaccine, which is expected to launch into a large market. In its first year, the older adult RSV market was $2.5 billion in sales, and analysts expect the older adults' market to grow between $6 billion and $8 billion per year. With marketing application filed in markets globally, we are anticipating approval beginning in the first half of 2024. In the U.S., we're targeting a launch after the June ACIP meeting.
We are very excited to bring a product from a strong differentiated profile to market. Our vaccine has a strong efficacy and safety in clinical trials, and we'll be the only product available in the pre-lled syringe or PFS presentation.
Let me now double-click on what we believe are the benefit of PFS. We recently published a time and motion study that shows faster preparation time for PFS relative to vaccines that require constitution. We call that both RSV combination vaccines on the market require multiple steps to prepare their vaccines for administration.
One vaccine requires process and the overall next steps to prepare. Our PFS presentation is ready to use vaccine straight out of the box. The study from the PFS presentation to be 3x to 4x more efficient as measured by preparation time. Details from the study can be found through the link on the slide.
We believe our PFS presentation for RSV vaccine has the potential to ease the personal burden on pharmacies during the fall respiratory season. The pharmacy chains [indiscernible] independent pharmacies and we're looking forward to the launch.
Let me close with major upcoming pipeline milestones. While we're excited about the commercial prospects for the year, we're even more excited about the upcoming pipeline milestone and the effect they will have on our commercial outlook for the next several years serving patients.
In respiratory vaccines, we are eagerly awaiting the approval of RSV and the [indiscernible]. We are also waiting for data for RSV in the age group 18 and above. We are in discussion with regulators on our flu program and intend to file in 2024. We won next-gen COVID vaccine and on [indiscernible], we are pleased with a positive Phase III immunogenicity data and are engaging with regulators. Our flu plus COVID vaccine combo should get this Phase III data soon.
In latent with CMV fully enrolled and at current cases, we look forward to potential for Phase III data efficacy data in 2024. In our INT program, we're looking forward to completion of enrollment for Phase III adjuvant melanoma study. In addition, we are keen to discuss the possibility of accelerated approval with regulators based on Phase II study data.
As we shared before, there are 3 things we view as necessary before we could consider pursuing fed approval for INT. First, durability data from our Phase II study, which we announced in December last year; second, a substantially enrolled Phase III adjuvant melanoma study; and third, manufacturing readiness at the Marlborough site. And last but not the least, our revenue portfolio, we look forward to initiating pivotal study for PMMA.
This milestone will represent continued progress towards our mission to deliver the greatest possible impact to people for mRNA medicines. And asModerna, we are dedicated to achieving them all. Every data continues to confirm the power of our platform and its breadth in the service of patients. Two important save a date for your calendars. We will discuss our COVID program in Chicago on June 1, and our annual R&D Day will be held in New York the morning of September 1.
Thank you for listening, and we look forward to taking your questions. Operator?
