Thank you, Mark. In addition to the financial results, I will discuss now, you can find additional information in our Form 10-Q, which we filed earlier today. Our cash, cash equivalents and the carrying value of investment grade security, including accrued interest were approximately $27.4 million at March 31, 2021, compared to $29.2 million at December 31, 2020. Research and development revenue for the quarter ended March 31, 2021 increased to approximately $461,000 compared to $315,000 for the same period a year ago. Cost of the research and development revenue for the quarter ended March 31, 2021 increased to approximately $391,000 compared to $278,000 for the same period a year ago. The increase in revenue and costs of research and development revenue for the three months ended March 31, 2021 reflected that the increase the number of ongoing research collaborations to eight compared to five collaborations for the same period a year ago. R&D expenses for the three months ended March 31, 2021, increased to approximately $1,808,000 compared to $755,000 for the same period a year ago. The increase primarily reflected Phase 1 clinical trial costs of DYAI-100 or COVID-19 vaccine in the amount of $882,000 and the additional cost of $159,000 related to our other internal research projects. G&A expenses for the three months ended March 31, 2021, decreased 6% to approximately $1,554,000 compared to $1,653,000 for the same period a year ago. The decrease principally reflected reductions in travel and rent expenses of $65,000. Insurance and other outside services of $47,000, other decrease of $30,000 offset by increase in legal expenses of $43,000. Interest income for the three months ended March 31, 2021 was approximately $26,000 compared to $168,000 for the same period a year ago. The decrease was primarily due to the lower balance of held-to-maturity, investment securities and the less reinvestment as a result of the decrease of interest rates. Net loss for the three months ended March 31, 2021 was approximately $3.3 million or $0.12 per share, compared to $2.2 million or $0.08 per share for the same period a year ago. Looking forward, we maintained our guidance for our total cash burn for 2021, which we expected to be in the range of $10 million to $12 million in inclusive of the Phase 1 clinical trial and our other ongoing internal research projects. We believe we have sufficient funds to provide at working capital needed for our research and operations for the next couple of years. With that, I will now ask the operator to begin our Q&A session. Dr. Ronen Tchelet and Matthew Jones will be joining Mark and I to answer your questions. Each caller will be allowed one question and one follow-up question to provide all callers an opportunity to participate. If time permits, the operator will allow additional questions from those who have already spoken. Operator, back to you.
