Yes but cake is dangerous for some people with egg allergies I don't get why people are more suspicious of a vaccine than the foods they buy off the supermarket shelf. I really don't think there is a hidden agenda here. I also don't get the comparison with Thalydimide... sure medical professionals will never know how everything affects everyone but I do believe them when they say they have seen more deaths (due to contracting the virus) than birth defects from the H1N1 vaccine. At one stage there were half a dozen pregnant women on life support (due to having contracted H1N1) in one Sydney hospital alone the last time it swept through. BUT I still believe that all of us need to weight up our individual intuitive response to this. I agree it is not for everyone. But I suspect it is safe for the majority.
