Blog:Babies’ breathing problems vaccine ‘closer’
The British Lung Foundation says it is closer to finding a vaccine for breathing problems suffered by babies in winter.
Experts believe the results of a three year study give them a better understanding of what causes the viral infections common amongst children in the first year of their lives.
They have identified how infants’ immune systems react to these infections - called bronchiolitis - which are the greatest cause of hospital admissions among babies in the developed world.
The condition often starts in infants as a common cold but then develops into breathlessness.
The research team headed by Dr Imran Hussain at Southampton General Hospital studied the immune responses of asthmatic and non-asthmatic children by observing white blood cells collected from their tonsils.
They were able to gain a clearer understanding of how the blood cells react to the most common form of bronchiolitis - respiratory syncytial virus (RSV).
The project identified RSV infections as causing harm to the immune system that would normally protect children from allergic reaction.
