International healthcare customers should be aware that no vaccination can ever provide "perfect protection" against the influenza virus, but some at-risk groups should think about getting one anyway.
This is the view of Dr Catherine Hood, scientific adviser to Mentholatum responsebeta anti-viral hand sanitizer, who noted that some people should seek medical advice about taking precautions against flu.
"All people over 65 years old, people with chronic illness or severe respiratory problems like asthma, those who have a weakened immune system through illness or medical treatment and pregnant women should all talk to their doctor about the flu jab," she said.
For elderly individuals, a bout of flu can lead to complications such as bronchitis or pneumonia, which would require medical treatment and possibly result in a claim made on their expat insurance.
Dr Hood's advice comes after the UK's Health Protection Agency noted that just 40 per cent of people in 'at-risk' groups are taking up the offer of vaccination against flu.
