The immunisation of children in large scale was started in Sri Lanka in in nineteen sixties.There were no deaths related to immunisation up to 2000.Now deaths occur related to immunisation and workshops are held to discuss safe immunisation. (like safe sex) .In early days only good quality products were available.Now mushrooming drug companies produce substandard vaccines which are being used in immunisation projects for reasons best known to health authorities.
The whole process has made parents to loose confidence in immunising children.This will lead to poor immunisation uptake figures. High immunisation uptake figures of Sr Lanka ,about which we can be proud of is the result of many generations of hard working doctors. There seems to be serious detrioration of the immnisation process at the turn of the cenutry.
