215 Patients:
H1N1 critically illness mostly affects young adults and is often fatal
JAMA 12 October 2009
Conclusion:
”Our data suggest that severe disease & mortality in the current outbreak is concentrated in relatively healthy adolescents and adults between the age of 10 and 60 years, a pattern reminiscent of the W-shaped curve seen only during the 1918 H1N1 Pandemic”
JAMA 12 October 2009

The Vaccine
“The A H1N1 Vaccine is made exactly by the same manufacturers with the same processing, the same materials, as we make seasonal flu vaccine which have extraordinarily good safety record”.
WHO Centre, IC London
The Vaccine
"The risks associated with not getting the H1N1 vaccine are far greater than the sore arm that may result from getting the shot"
"This virus has the potential to cause serious illness and death. Receiving a vaccination is an effective way to help fight the spread of the virus."
