Based on the previous posters question about risks, here is a little info on adverse effects resulting from pertussis vaccine, it might be useful when weighing up risk of vaccine versus risk of adverse effects. An example here is that a serious allergic reaction has an of occurence of less than 1 out of a million doses.
Even the chance of a high fever is approximately 1 out of every 16,000 doses, so extremely small.
So when we compare that to the risk of catching whooping cough, having short or long term adverse effects and even death the numbers tell a pretty convincing story, which is why the government and health professionals advocate their use.
And as in any vaccine, it is not 100% - it is approximately 80% and above with regard to efficacy which means you are reducing yours and your babies chances of getting it substantially…at least you are doing everything in your power any way.
If I have time later I will post some more scientific evidence for you. But I have to go and get breakfast for everyone at the moment.
