Well they would, wouldn’t they? From Medical News Today:
After analyzing over 1,000 research papers, a report issued by the IOM (Institute of Medicine) found no evidence linking vaccines to autism or type 1 diabetes risk, and very few other health problems caused or clearly linked to vaccines. According to a committee of experts who reviewed the scientific studies, convincing evidence was found of 14 health outcomes associated with vaccines, including fainting, brain inflammation and seizures, however, their occurrences were found to be very rare.
Some less clear data linking certain vaccines to four other effects, including temporary joint pain and allergic reactions were also found. Regarding other suggested adverse effects, the experts said there was inadequate data.
The IOM says that this review will help the HHS administer the VICP (Vaccine Injury Compensation Program), which depends on science-based evidence when deciding on vaccine-related side effects. The HHS (Department of Health and Human Services) asked the IOM for a comprehensive review on eight vaccines covered by VICP.
