From the report:
QUOTE
If initial containment is not effective, it is anticipated that
global spread will occur as soon as 3 months after the
emergence of a pandemic virus, with outbreaks reported
from all continents. By that time, large-scale influenza vaccine
production is likely to have only just started. This scenario
would indicate that influenza vaccines will be available
only to a small minority of countries and their populations.
The current manufacturing capacity for influenza
vaccine is driven by demand for seasonal vaccine
(~300 million doses per year). If the antigen content of a
pandemic vaccine was similar to the seasonal one, and if
the production yields were the same as for seasonal vaccine,
then this would result in 900 million pandemic vaccinations
available per year. It is important to consider that
>65% of world influenza vaccine is produced in Europe
and that 3 companies hold >80% of the manufacturing
capacity. Several technical solutions are to be explored to
shorten the influenza pandemic vaccine gap. However, in
the short and mid-term (up to 5 years), inequitable access
to influenza pandemic vaccines will remain a reality, and a
profound change is unlikely without new vaccines and immunization
approaches. It is important therefore that
countries without access to pandemic vaccines have other
public health control measures in place.
