Today, GlaxoSmithKline KK (GSK) in Japan confirmed that it has reached an agreement with the Government of Japan (Ministry of Health, Labour and Welfare) to amend its existing contract to receive approximately 68 per cent of the ordered vaccine.

The Company is currently in ongoing discussions with a number of governments worldwide regarding their specific pandemic planning needs, including governments who are changing their planned immunization programs.
