More than half of children taking the swine flu drug Tamiflu experience side-effects such as nausea and nightmares, research suggests.
Britain is offering the vaccine to anyone who wants it, and overall is very concerned with the number of new cases continually popping up.
In children, side-effects of Tamiflu include:
- stomach cramps
- trouble sleeping
- neuropsychiatric side-effects (nightmares, the inability to think or act clearly)
