THE HSE DESTROYED more than €6 million worth of unused vaccines between 2005 and the end of 2010.
According to the Medical Independent, the stocks of vaccines were destroyed because they had expired or because of a break in the cold chain.
The HSE said the figure is within the international standards as the World Health Organisation (WHO) recommends that destroyed vaccines should account for less than 5 per cent of total vaccine spend.
In the five-year period, the HSE purchased €91 million of childhood vaccines and it returned €1.2 million worth for destruction.
Between 2005 and the end of 2010 the HSE destroyed €5.06 million worth of unused season flu and H1N1 vaccine.
