Personally I think this is one decision that needs to made carefully. According to the Government we should all immunise our children and any other "at risk" person. However, there is a lot of other reputable information out there to suggest that there are risks with this approach. This vaccine in particular was rushed into circulation and there has been much debate about the standard of testing (or lack thereof) and also the multi-use vials it comes in. Neither of my boys have asthma or other complications, so it is not the same situation, but we have decided that they will not have this vaccine despite the pressure from the government to do so (we have had brochures telling us we should, and where to get it for free from both kindy and school).
