Dr Sarah Wollaston MP has made a heartfelt plea to her constituents to get their children vaccinated following an outbreak of measles in Wales.
The Devon MP who was a practising GP before her election, wrote on her blog that many of her constituents mistakenly believed that homeopathy would protect their children.
The real 'herd' effect may be an unwarranted fear that vaccination is harmful or the belief that 'natural' methods like homeopathy can boost a child's immunity and thereby offer a safe alternative to protect against this virus.
Most homeopaths do encourage parents to vaccinate alongside the use of homeopathy. Given the current outbreak in Wales, it is also time for their their governing bodies to issue an unequivocal statement that homeopathy offers no protection whatsoever against this serious illness.
The British Homeopathic Association said that there was no evidence to suggest that homeopathy should be used to prevent measles and stressed that parents should give their children the MMR vaccine.
A man who died in from a suspected case of measles in Wales was infected with the disease at the time of his death, health officials said.
A mother convinced the MMR vaccine led to her son's autism has not immunised her daughter, despite the link being disproved.
