Association of autistic spectrum disorder and the measles, mumps, and rubella vaccine: a systematic review. Anonymous (not verified) Tue, 08/24/2021 - 11:42

OBJECTIVE: To systematically review the evidence for and against the existence of an association between autistic spectrum disorder (ASD) and the measles, mumps, and rubella (MMR) vaccine. DESIGN: We conducted a systematic review of the medical literature to identify all controlled epidemiological articles examining for an association between ASD and the MMR vaccine. We extracted data from the articles on the characteristics and objectives of the study as well as evidence of an association. RESULTS: Twelve articles met the inclusion criteria. One study found no difference in the rates of ASD and the MMR vaccine in children who were vaccinated and those who were not. Six studies examined for evidence of an increase in ASD associated with an increase in the MMR vaccine coverage, none of which showed evidence of an association. Four studies examined if a variant form of ASD was associated with the MMR vaccine, none of which showed evidence of an association. Eight studies attempted to determine if there was a temporal association between developing ASD and receiving the MMR vaccine. Of these, 1 study identified an increase in parental concern in the 6-month period following vaccination with MMR in one of its analyses. The results of all other studies showed no association between ASD and the MMR vaccine.CONCLUSIONS: The current literature does not suggest an association between ASD and the MMR vaccine; however, limited epidemiological evidence exists to rule out a link between a rare variant form of ASD and the MMR vaccine. Given the real risks of not vaccinating and that the risks and existence of variant ASD remain theoretical, current policies should continue to advocate the use of the MMR vaccine. PMID: 12860782

Changing attitudes towards polio vaccination: Anonymous (not verified) Tue, 08/24/2021 - 11:42

We compared the impact of epidemiological evidence and anecdotal evidence on changing vaccination attitudes amongst alternative medical students. Ninety-seven students were randomized to either an evidence-based lecture on the benefits of the polio vaccine on population health or a presentation from a visibly affected victim of polio. We compared change in responses to a survey measuring vaccination attitudes between the two groups. The follow-up rate was 73%. There was no statistically significant difference between the two groups in change in response to any of the survey questions. In a post hoc analysis we found that 25% of students were less likely to recommend the vaccine after being provided with evidence supporting vaccination. These findings suggest that confronting deeply held beliefs regarding vaccination may paradoxically strengthen these belief systems. PMID: 15811647

Parents experiences in discussing vaccination with healthcare providers Anonymous (not verified) Tue, 08/24/2021 - 11:41

BACKGROUND: Parents who choose to selectively vaccinate or avoid vaccination for their children may do so at risk of compromising relations with their family physician or pediatrician. Groups that are associated with reduced rates of pedicatic vaccination, such as parents who access naturopathic care, may be particularly vulnerable to this issue. METHODOLOGY/PRINCIPLE FINDINGS: In March through September 2010, we administered a 26-item cross-sectional survey to 129 adult patients, all of whom were parents with children ?16 years of age, presenting for naturopathic care in Ontario, Canada. Ninety-five parents completed the survey (response rate 74%), and only 50.5% (48 of 95) reported that their children had received all recommended vaccines. Most parents (50.5%; 48 of 95) reported feeling pressure to vaccinate from their allopathic physician and, of those who discussed vaccination with their physician, 25.9% (21 of 81) were less comfortable continuing care as a result. Five percent (4 of 81) of respondents were advised by their physician that their children would be refused care if they decided against vaccination. In our adjusted generalized linear model, feeling pressure to vaccinate (odds ratio [OR] = 3.07; 95% confidence interval [CI] = 1.14 to 8.26) or endorsing a naturopathic physician as their most trusted source of information regarding vaccination (OR = 3.57; 95% CI = 1.22 to 10.44) were associated with greater odds of having a partially vaccinated or unvaccinated child. The majority (69.6%; 32 of 46) of parent's with partially vaccinated or unvaccinated children reported a willingness to re-consider this decision. CONCLUSIONS/SIGNIFICANCE: Use of naturopathic care should be explored among parents in order to identify this high-risk group and engage them in discussion regarding pediatric vaccination to encourage evidence-based, shared decision making. Physicians should ensure that discussions regarding vaccination are respectful, even if parents are determined not to vaccinate their children.

The development of vaccination perspectives among chiropractic, naturopathic and medical students: a case study of professional enculturation

The development of vaccination perspectives among chiropractic, naturopathic and medical students: a case study of professional enculturation Anonymous (not verified) Tue, 08/24/2021 - 11:41

An important influence on parents’ decisions about pediatric vaccination (children under 6 years of age) is the attitude of their health care providers, including complementary and alternative medicine (CAM) providers. Very limited qualitative research exists, however, on how attitudes towards vaccination develop among healthcare professionals in-training. We explored perspective development among three groups of students: medical, chiropractic, and naturopathic. We conducted focus group sessions with participants from each year of study at three different healthcare training programs in Ontario, Canada. Semi-structured and open-ended questions were used to elicit dynamic interaction among participants and explore how they constructed their attitudes toward vaccination at the beginning and part way through their professional training. Analyses of verbatim transcripts of audiotaped interviews were conducted both inductively and deductively using questions structured by existing literature on learning, professional socialization and interprofessional relations. We found five major themes and each theme was illustrated with representative quotes. Numerous unexpected insights emerged within these themes, including students’ general open-mindedness towards pediatric vaccination at the beginning of their training; the powerful influence of both formal education and informal socialization; uncritical acceptance of the vaccination views of senior or respected professionals; students’ preference for multiple perspectives rather than one-sided, didactic instruction; the absence of explicit socio-cultural tensions among professions; and how divergences among professional students’ perspectives result from differing emphases with respect to lifestyle, individual choice, public health and epidemiological factors—rather than disagreement concerning the biomedical evidence. This last finding implies that their different perspectives on pediatric vaccination may be complementary rather than irreconcilable. Our findings should be considered by developers of professional and interprofessional educational curricula and public health officials formulating policy on pediatric vaccination.
