Thanks, Stan, and good afternoon to everyone on the call. I’ll start with an update on our Phase 3 trial of RSV named Prepare, which is designed to demonstrate protection of infants by maternal immunization. As reminder, the Prepare trial is supported by a grant of up to $89 million from the Bill & Melinda Gates Foundation whose goal is to reduce global infant mortality through an infected RSV vaccine. The Prepare trial is a randomized, observer-blinded, placebo controlled trial that utilizes a group sequential design, offering flexibility in trial size that is responsive to the rate of endpoint event and evolving evidence of efficacy, while maintaining and integrity of the blinded trial. The trial includes a single injection given between 28 and 36 weeks of estimated gestational age. The primary objective of the Prepare trail is to determine the efficacy of maternal immunization with the RSV F Vaccine against symptomatic RSV lower respiratory tract infection with hypoxemia in the infants through minimum of first 90 days of life. Participants are being recruited and vaccinated at global clinical sites based in the timing of each region’s RSV season. This trial will include a minimum of 4,600 participants. As we previously noted in November, we finished year one in U.S., South Africa, Australia, New Zealand and Chile. In the year two, we’re in the process of adding multiple Northern and Southern hemisphere sites. Enrollment in Southern hemisphere is progressing well, and we’re excited to carry that momentum forward to new sites. As a reminder, we will follow maternal participants for nine months and the infants for one year after they are born. As we’ve discussed previously, this trial is being monitor by Data Safety Monitoring Board that is out of necessity unblinded. The DSMB’s primary mandate is to look over evolving aggregate safety data. To do this, it reviews the data monthly in unblinded fashion during enrollment. Today, this group has met many times and the former recommendations made by the DSMB after review of the data, each meaning have been to continue the trial without operation. That means there have been no apparent safety concerns and no advisement to modify or hold the trial. As Stan mentioned, our discussion with the FDA to-date lead us to believe, we will be allowed to conduct an information analysis as early is the end of 2017, which will provide us an indication on the vaccine’s potential efficacy as to primary endpoint. We look forward to providing an update, once we have more specific information in agreement with the FDA. I’ll now move on to our RSV program in older adults. As Stan mentioned, in January, we initiated a Phase 2 clinical trial in this population, which we refer to as E205. The objective of this trail is to assess the safety and immunogenicity of one and two dose regimens of the RSV F Vaccine with or without aluminum phosphate or proprietary Matrix-M adjuvant. This trial is a randomized, observer-blinded, placebo-controlled trial that has enrolled 300 older adults in the southern hemisphere. We’re conducting this trial in the southern hemisphere to avoid the ongoing RSV season in the northern hemisphere and to ensure that the immunogenicity results from the trail are solely resulting from the vaccine and not from natural infection from circulating virus. We expect the trial will determine the effect of adjuvantation and/or a two dose regiments on the quality and quantity of the RSV related immune response in older adults. The top line results from the study are expected in the third quarter of 2017. Results from this trial will be interpreted in the context of our learnings from the previous RSV F Vaccine Phase 2 and Phase 3 studies, as well as the ongoing epidemiology studies and our discussions with KOLs. We expect to use the 205 results in augmented epidemiology data to map out our path forward for this important vaccine, and are considering older adult population or initially working in high-risk population. Moving now to a brief update of our current status of the Resolve Phase 3 trial of RSV F Vaccine in older adults from which we announced data last September. We continue to analyze the data from the Resolve trial in order to better understand these results and to map a path forward for this important program in the older adult population. Our efforts include analyses of existing immunogenicity and efficacy data, and the application of new assays to test the archived samples. We have also undertaken external epidemiologic studies to further understand the attack rate, healthcare burden and seasonality of RSV disease in older adults. As I mentioned earlier, we expect these analyses to provide important information and context when we review the results from the ongoing E205 clinical trial in older adults. Taken together, the data from the current Phase 2 and the evaluation of our Phase 3 data as well as other past clinical trials in older adults will help us determine our next steps. Now, moving to our Zika vaccine program, we are conducting non-human primate challenge studies with colleagues at Harvard. Data analyses from our first study show that does responses reduction in the peak Zika viremia of up to 94% by vaccine induced antibodies and suggested levels of immune response that Novavax candidate could provide sterile immunity and desired outcome. We’ve conducted follow-up formulation studies to suggest that we can achieve higher immunogenicity through relatively simple formulation improvement. Such new vaccine formulations are being evaluated as we continue to conduct IND-enabling pre-clinical studies including studies both in non-human primates and other animal models. Our goal is to initiate a Phase 1 clinical trial of our Zika envelope dimer nanoparticle vaccine candidate later this year. Finally, regarding flu, as you know, we continue to develop recombinant nanoparticle version of our flu vaccine. This construct should have a number of advantages over our previous VLP vaccines including purity and stability, and importantly we believe the ability to simulate broadly neutralize the antibodies. We’re targeting the product profile that could be adjuvant with our Matrix-M adjuvant and that could compete with Sanofi’s high dose vaccine in the elderly market. Our preclinical studies have shown that our nanoparticle flu vaccine candidate does indeed elicit broadly neutralized antibody and it’s our goal to move this program into a Phase 1 clinical trial by the end of this year. So, with that, I’ll now turn the call over to Buck to review our financials. Thank you.
