You could probably ask that question about other vaccines too. Look at Prevenar, the most recent addition. Now reccomended to all children despite evidence from the US that there was no real decrease in IPD. Actually since the vaccine has been introduced, pneumococcal meningitis in children under one has increased in the US. Some of the new serotypes are antibiotic resistant - the vaccine could actually do more harm than good. Yet it is now routinely given to most children. Why? "
When Pediacel was introduced in 2004 (after some "iffy" trials), it was recommended to the government by a committee that had at it's head Prof. Langman, who also happens to receive funds from MSD (the vaccine manufacturers) for research at his dept at Birmingham university. Conflict of interests?
Many other members of the JVIC have conflicts of interests with vaccine manufacturers. It really isn't much different here to the US.
I am pretty sure, from the evidence that they will not introduce the CP vaccine here. It is pretty ineffective long term and the increase in shingles is not desirable.
