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."
