It has taken a long time and they have overcome many hurdles along the way, but it is an inspiring example of that perseverance pays. The approval has received a lot of attention in the US. Protein Sciences is planning to have a limited launch of the product in February 2013 with the full launch occurring in time for the 2013/14 influenza season. Diamyd Medical holds about 8 percent of the shares in Protein Sciences. Flublok is the first vaccine against seasonal influenza that is manufactured using modern recombinant technology to reach the US market. The advantages compared to traditional vaccine manufacturing are that it requires less lead time to manufacture after the identification of the year's flu strains, the vaccines are not produced in eggs and therefore do not contain egg derivatives, and the manufacturing does not require the use of live influenza virus, the mercury compound thimerosal or antibiotics. Protein Sciences is also developing a similar vaccine against pandemic influenza in collaboration with the Biomedical Advanced Research and Development Authority, a division of the US Department of Health and Human Services. We see a continued strong interest from researchers in our own diabetes vaccine Diamyd®. Our plan is to encourage researcher initiated studies, where Diamyd® is tested in combination with other drugs, in limited, less costly clinical pilot studies in recent-onset type 1 diabetes. By attacking the disease from several sides with combination therapy, the idea is to provide a better chance for the diabetes vaccine to intervene in the autoimmune disease process underlying type 1 diabetes. We also want to see more researcher initiated studies started to test the diabetes vaccine in people who have not yet developed type 1 diabetes, but are demonstrated to have an elevated risk of developing the disease. There is already such a pilot study ongoing in Sweden, where results are expected in 2015. By collaborating with externally funded research groups, we will be able to test more treatment paradigms than if we would have conducted and funded all the studies ourselves. On January 31, we have an Extraordinary General Meeting in Stockholm. The meeting will resolve on the distribution of SEK 118 million, corresponding to about a third of the Company’s cash, to our shareholders through a share redemption program. If the meeting resolves on the redemption of shares, the shareholders will receive detailed information on the redemption procedure.
