A study has found an increase in vitamin A poisonings around the time it was promoted as a treatment for measles. The increase in poisonings is reported to be nearly 40 percent, although the exact circumstances and connections to the promotion are not entirely clear. Reports suggest that the promotion of vitamin A as a measles treatment by RFK Jr. may have contributed to the rise in poisonings, but other factors, such as misinformation and media coverage, may also have played a role.
