The first vaccine which protects children against hand, foot and mouth disease has been reported by scientists in China.
The infection causes a rash and painful blisters, but in some cases results in brain infections which can be fatal.
A trial involving 10,000 children, published in the Lancet, showed the vaccine was 90% effective against one virus which causes the disease.
It does not protect against other viruses that result in the disease.
Viruses can cause large outbreaks of hand, foot and mouth disease. In 2009, there was an outbreak in China involving 1.2 million people. Nearly 14,000 people had severe complications and 353 people died.
Groups of researchers in Jiangsu province and Beijing tested a vaccine made from a deactivated enterovirus 71 (EV71), which causes the disease.
Two jabs were given to children between six and 35 months old. They prevented 90% of cases of hand, foot and mouth disease caused by EV71.
