By age six, American children receive around 48 doses of 14 different vaccines, and this film asks why so little long-term safety research accompanies that schedule. Pediatricians and scientists interviewed here argue that vaccine components, including thimerosal and aluminum, can trigger immune or neurological damage in susceptible children, citing cases of autism, Guillain-Barré syndrome, macrophagic myofasciitis, encephalitis, and paralysis as evidence. They contend that most safety studies are funded by the pharmaceutical industry itself, a conflict of interest the film returns to repeatedly, and note that thimerosal is cheaper to manufacture with than mercury-free alternatives. Public health officials and industry representatives push back, pointing to decades of safety data going back to the 1920s and rejecting any causal link. The film sits inside that standoff rather than resolving it, using the interviews to argue that parents are being asked to accept an expanding vaccine schedule without equivalent scrutiny of its risks. It closes by calling for independent, industry-free research rather than declaring vaccines guilty outright.
