Statement re MVA Cambridge, UK and Cambridge, Massachusetts - 22 August 2005 - Acambis plc ("Acambis") (LSE: ACM, NASDAQ: ACAM) Acambis notes the press release issued by Bavarian Nordic A/S ("BN") after the market close on Friday, 19 August. In that, BN said that it had filed two legal actions against Acambis in the US, in relation to the intellectual property on its MVA smallpox vaccine. Acambis has not yet received a copy of the legal claims, so is unable to comment on any of the specifics. However, based on the information in BN's press release, Acambis believes the claims are without foundation. To the extent that it is required to do so, Acambis will be vigorously defending its legal position. Gordon Cameron, Acambis' Chief Executive Officer, commented: "We have always maintained, having consulted throughout with external patent counsel, that we have freedom to research, develop, manufacture and sell our MVA vaccine candidate. That position still stands and we do not expect either of the BN legal actions to affect that position, in particular for the current US Government tender process, for which a Request for Proposals was issued last week. We continue to believe that we are very well positioned to win an award under that process." -ends- Enquiries: Acambis: Gordon Cameron, Chief Executive Officer: Tel +1 (617) 761 4200 David Lawrence, Chief Financial Officer: Tel +44 (0) 1223 275 300 Lyndsay Wright, VP, Communications and Investor Relations: Tel +44 (0) 1223 275 300 Financial Dynamics: David Yates/Lucy Briggs: Tel +44 (0) 20 7831 3113 About Acambis Acambis is a leading developer of vaccines to prevent and treat infectious diseases.
