I've mentioned the problem of deaths following the pentavalent vaccine several times. This is the sort of information that undermines trust in vaccines.Three deaths in Sri Lanka prompted the government to suspend the use of the vaccine. Under Right to Information we know that up to August 2016 there have been 237 deaths reported to the government here within 72 hours of vaccination with Pentavalent. We examined deaths in states which were giving DPT and Pentavalent vaccine concurrently. We were careful to do this so that comparisons are done in the state only after AEFI surveillance was improved in the state with introduction of Pentavalent vaccine. Deaths with Pentavalent were double that with DPT. It is often said deaths following vaccination are coincidental natural deaths and it is the normal rate of sudden unexplained deaths (SIDS). If all deaths with DPT are natural deaths and that is the standard SIDS rate, then the excess deaths with Pentavalent vaccine must be caused by this vaccine.
