on vaccine safety.” The studies that they chose to use had to have a controlled mechanism and
active surveillance, and all were within the United States. The results of the study were “there is
strong evidence that MMR vaccine is not associated with autism.” The official conclusion from
the study is that “we found evidence that some vaccines are associated with serious adverse
events; however, these events are extremely rare and must be weighed against the protective
benefits that vaccines provide.” The ‘some vaccines’ mentioned in the results is in reference to
the moderate evidence they found about rotavirus vaccines being linked with intussusception, not
MMR with autism.
In comparison with Thimerosal in Vaccines I found that both talk about the safety of vaccines.
The FDA conducted a “comprehensive review of the use of thimerosal in childhood vaccines”
and found “no evidence of harm from the use of thimerosal as a vaccine preservative, other than
local hypersensitivity reactions.” They both mention the decrease in vaccinations due to concerns
of their safety, and they determined that they were safe through a study of its effects on the
youth. The vaccine safety source provides more background information about thimerosal in vaccines,
how it is used as a preservative, the toxicity, as well as the actions that the FDA has taken.
Whereas, my other source conducts a systematic review of vaccine work in the United States,
including sources from Pubmed and the Institute of Medicine. The results are also similar to each
other as well as to the results in most of my other sources.
This source will be used in my writing to support my claim, and is useful as it is a systematic
review of many studies on the matter, with selection guidelines so that it is controlled review. It
will be used in my writing to address concerns people have or have had about vaccine safety. The
research was conducted from that of reputable organizations, which helps me support the claim
further. This source brought to my attention the moderate evidence of rotavirus vaccines association
with intussusception, which is a treatable medical emergency.

In this source published on Focus for Debate, their argument is that vaccines do cause autism. It
recognizes CDC’s official statement in the writing and then goes on to say that the United States
Vaccine Injury Compensation Program “has awarded financial compensation to parents of autistic
children because vaccines could not be ruled out as the cause of neurological damage.” An-
