Czech health authorities said Friday they had cancelled around a third of their order of one million H1N1 vaccines from British pharmaceutical company GlaxoSmithKline (GSK).
"Under a supplementary part of the contract with GSK, the Czech Republic will obtain 700,000 doses," Health Minister Dana Juraskova said.
"This modification of the contract isn't linked to any kind of a financial penalty," she told journalists.
Health authorities planned to expand the use of the vaccine beyond the initial project which covered 500,000 people including doctors, those "necessary for the functioning of state" and high-risk cases, Juraskova said.
Czech health authorities said Thursday the H1N1 virus had claimed 100 lives in the republic of 10.2 million people.
A total 2,434 cased of H1N1 were confirmed while 64,066 doses of the vaccine had been administered as of Thursday, they said.
