In 1979 11 babies died within 72 hours after receiving the DPT vaccine

DPT vaccine Lot #64201 was given to 9 of the babies that died. (SIDS). Sudden Infant Death Syndrome. They came up with a syndrome for the babies deaths to make it seem the vaccine was not the cause. "We have in idea why the babies died" They died from SIDS.
The Pharmaceutical companies response was to mix all the lot numbers when shipping to separate locations. This only spreads out the deaths so there is only one death in 11 separate location and won't be noticed as much, essentially hiding the deaths from the public. All vaccine companies now do this as standard procedure to hide the deaths and injuries.

This is just one of the thousands of things the pharmaceutical companies do to hide the damage from their vaccines.
