"So far the results have been consistent in indicating that it is better to receive a live vaccine after a non-live vaccine than a non-live after a live vaccine ... Hence, it could have major effects on mortality and morbidity and health care costs if immunisation programmes implemented a “live-vaccine-last” policy."
A letter in BMJ Rapid Responses yesterday co-authored by veteran Danish vaccine researchers Christine Benn, Peter Aaby and their colleague Signe Sorup warns of the risk to morbidity and mortality if non-live vaccines are administered after live virus vaccines, rather than in the opposite sequence. The authors are writing about the non-specific effects of vaccines on health. The flagging up of adverse consequences after decades of administration indicates the chaotic, and unrecorded effects of vaccine programs across the globe. The letter talks about the sequence of administration when of course live and and non-live vaccines are often administered together.
While the authors talk about modifying practice, what continues to be troubling is the random recklessness and negligence with which programs are assembled and the failure to monitor the long term consequences for health of vaccination. For all those who have had to bear the consequences looking at it decades later is of course only slightly better than nothing.
