Janssen Vaccines, formerly Crucell, is a biotechnology company specializing in vaccines and biopharmaceutical technologies.It was formed when Johnson & Johnson acquired the Dutch biotech company Crucell based in Leiden and placed it in their pharmaceutical division.__TOC__
In 1993 Introgene, Crucell’s predecessor, was established as a spin-off of Leiden University. The company formed a partnership with Genzyme to collaborate on its vector technology and viral-based products. In 1999 the company founded Galapagos Genomics as a joint venture together with Tibotec. In 2000 IntroGene acquired U-Bisys to form Crucell.
In 2006, Crucell and Swiss Berna Biotech; Swedish SBL Vaccines and US-based Berna Products joined forces to become the sixth largest vaccine company worldwide, with their own clinical programs.
On 7 January 2009 Crucell released a press release saying Crucell and Wyeth were in discussion on a merger of the two companies. On 26 January 2009 Crucell released another press release saying the discussions on a combination of Crucell and Wyeth was discontinued due to Pfizer's acquisition of Wyeth.
In September 2009 Johnson & Johnson bought 18% stake in Crucell for €302 million in order to collaborate on the development of a flu vaccine.[1] This followed Crucell's discovery of CR6261, a potent human antibody that neutralizes a broad range of influenza A viruses. J&J acquired the rest of the company in October 2010, taking its stake to over 95% by February 2011[2] [3] and delisting the company from stock exchanges two months later.[4]
After the takeover by Johnson & Johnson in 2011, Crucell was assigned to Janssen Pharmaceuticals division. In 2014, the subsidiary was renamed from Crucell to Janssen Vaccines.[5] [6]
