I still remember the trauma of childhood injections and have never really lost my fear of needles, tending to pass out when faced with an injection. I was interested to read this article which suggests some injections may soon become obsolete and be replaced with a vaccine that can be inhaled. Rather than being faced with the dreaded needle patients would simply breathe in fumes from a bag. Human trials on the vaccine will begin within the next few weeks and if successful could potentially lead to inexpensive vaccines for illnesses such as tuberculosis and cervical cancer. The bad news is, however, that it could take around five years to become available in Britain and whilst it may work with vaccines there are still blood tests to look forward to. :(
