Thank you, Rob. I'm very pleased to report on another quarter of strong financial performance. I'll highlight the key financial items and then review our updated full-year 2022 guidance and provide a few closing thoughts. Please note that all financial comparisons are versus the prior-year period unless otherwise noted. Please refer additionally to our press release and 10-Q for the detailed financial information. Beginning with our revenue performance, we delivered total revenue of $256 million for the second quarter of 2022, up 386% year-over-year. We're extremely excited about the commercial progress of Heplisav-B in the U.S. and now also in Germany. The second quarter marked another record breaking quarter total Heplisav-B net sales of $33 million, including approximately $1 million of sales associated with commercialization in Germany, and represents significant year-over-year growth of 139% for the franchise. Additionally, we continue to execute across our global portfolio of CpG 1018 adjuvant commercial supply agreements for COVID-19 vaccines, achieving $223 million in CpG 1018 adjuvant revenues with a gross margin of 67%. Included in this amount is approximately $55 million in revenue at 100% gross margin associated with the final delivery under our commercial supply agreement with Valneva. Now turning to expenses. Our research and development expenses for the second quarter of 2022 were $10 million, reflecting continued advancement of our ongoing pipeline programs in Tdap and shingles, as well as our funded Phase 2 contract with the DOD for an adjuvant in plague vaccine. Looking ahead, we are very encouraged by the continued progress in our clinical pipeline and look forward to multiple potential data catalysts across our portfolio by the end of the year as Rob highlighted. Selling, general and administrative expenses for the second quarter of 2022 increased to $36 million, compared to $22 million for the second quarter of last year primarily driven by increased headcount across field sales and G&A coupled with focused marketing investments to drive growth in Heplisav-B. Moving on to profitability. For the second quarter of 2022, we generated GAAP net income of $129 million or $1.02 per share basic and $0.87 per share diluted, compared to GAAP net income of $4 million, or $0.04 per share basic and $0.02 per share diluted in the second quarter of 2021. Now turning to the balance sheet, we ended the second quarter with a robust balance sheet including cash, cash equivalents and investments of $518 million. We believe this level of capital is sufficient to support our core business without the need to raise additional funds. Lastly, I'm pleased to refine our 2022 full-year financial guidance, including CpG 1018 adjuvant revenues of between $550 million to $600 million with approximately 60% gross margin for the year, which reflects the economics associated with the remaining firm orders under our commercial supply agreements for 2022. R&D expenses in the range of $50 million to $60 million, SG&A expenses in the range of $130 million to $140 million. And we are reiterating our previously guided interest expense of approximately $7 million. These refinements to our operating expense guidance reflect our disciplined approach to capital allocation, focused on selective investments to drive growth in Heplisav-B and thoughtfully advance our clinical pipeline to drive long-term shareholder value. We remain on track for another great year with anticipated record revenues for both of our commercial assets, continued progress and meaningful catalysts across our clinical portfolio, and a second consecutive year of profitability. Thank you everyone for your attention today. Operator, we would now like to open the Q&A portion of today's call.
