On Saturday 26th September a trial began involving 1,000 children to test two swine flu vaccines before the launch of a UK vaccination. The information is limited but the trial will allow the experts to observe immune reactions and any side effects which may occur.
The children participating in this trial are aged between six months and 12 years from Oxford, Southampton, London, Bristol and Devon. Participation in the trial is voluntary and consenting parents were be briefed on the risks. The children are given two doses of the vaccine three weeks apart, then a blood test three weeks after that.
The aim of the trial is to find out if one of the vaccines is better than the other in terms of immune reactions. They also want to ensure that the side effects are minimal before launching the UK vaccination programme.
One of the main problems the study seems to be having is recruiting enough children under the age of three, getting older children didn’t seem to be a problem just the younger ones, Doctor Saul Faust suggests that the younger children don’t usually respond to vaccines as well as adults and older children but says that they need to find out how the younger children respond before the vaccine becomes available to the UK. This could be because the younger children are deemed to be one of the high risk groups because young children, especially those that are under five, do seem to be at risk of serious illness. Also flu epidemics and pandemics are spread very efficiently by children.
The Department of Health has said that they will have enough vaccine for half of the population by the end of the year and that the high risk groups which are medical staff, the elderly and the very young will be immunised first.
