Reuters: H1N1 vaccine production far less than forecast – WHO

Production of H1N1 vaccine over the next year will be 'substantially less' than the 4.9 billion doses previously forecast but one dose should provide adequate protection, the World Health Organisation (WHO) said on Friday. Skip related content

Based on clinical test results from some 25 drugmakers, weekly production of the new vaccine will be less than 94 million doses, WHO spokesman Gregory Hartl said.

'The real figure will be substantially less than 4.9 billion (over the year),' Hartl told reporters.

But supply fears have eased as the northern hemisphere heads into winter and with major drug manufacturers reporting that a single dose is successfully providing immunity.

'All the clinical trial results that we have seen show that apparently one dose is enough,' Hartl said.

The United Nations agency previously forecast one third of the world's nearly seven billion people could be affected by the H1N1 pandemic, but so far the vast majority of victims are suffering only mild symptoms.

Health care workers and people at high risk, including pregnant women and those with underlying conditions such as asthma or diabetes, should be top priority for receiving the new vaccine, it says.
