The process of inducing the immune system or immunisation induces immune reactions. It is quite common to have the mild side effects described noted in the detail of this text. There is no proven causality between the more serious side effects described and the vaccine. Indeed the side effect profile detailed in this superficial article would certainly be superior to a commonly prescribed drug such as penicillin or even an over the counter one such as aspirin.
The induction of any aspect of the immune system is a source of potential risk. To look at this from another angle consider more ‘natural’ immune stimulants such as echinacea. In my admittedly limited experience with echinacea this natural remedy has been associated with one case of immune related paralysis, two cases of flares of autoimmune disease, and approximately 10 flares of allergic conditions. It is after all an immune booster so what else should we expect. Of course I cannot prove a causal association between echinaccea and the conditions I describe and unfortunately the capacity for reporting such reactions with complementary medications is limited (although increasing). This means we are unlikely to be able to make a clear judgement about the risks and benefits of many ‘natural’ remedies.
Vaccination has a risk benefit profile. Administration of any medication has a risk benefit profile. The process of informed consent allows individuals to make judgements about the suitability of vaccination for themselves. The information being gathered by the MHRA in the UK allow us to make these informed decisions. I’m sure those gathering this data would be dismayed at the way it has been manipulated in this article.
