There are many types of evidence such as scientific, historical and experiential. Science, like all other types of evidence, has it's strengths as well as weaknesses. Studies can be strongly or poorly designed and influenced by bias or any number of motivations. Data can be cherry-picked and study conclusions do not always match the evidence within. Here are a few questions to ask when critically assessing a study and it's findings:
A qualitative, systematic review argues the need for plant/oil-based medicines as alternatives to synthetic antibiotics, which are subject to pathogen resistance and negative side effects; and explores the effectiveness of essential oils as alternatives in the treatment of periodontal pathogens.
Clove essential oil significantly reduces pain responses in mice.
"The data indicate that unvaccinated children in the practice are not unhealthier than the vaccinated and indeed the overall results may indicate that the unvaccinated pediatric patients in this practice are healthier overall than the vaccinated."
Despite high levels of vaccination coverage, pertussis circulation cannot be controlled at all.
Immunocompromised contacts should be advised to avoid contact with stool from the Rotovirus immunised child if possible, particularly after the first vaccine dose for at least 14 days.
"Vaccinated adolescents and adults may serve as reservoirs for silent infection and become potential transmitters to unprotected infants (3-11). The whole-cell vaccine for pertussis is protective only against clinical disease, not against infection (15-17). Therefore, even young, recently vaccinated children may serve as reservoirs and potential transmitters of infection.”
"The apparent paradox is that as measles immunization rates rise to high levels in a population, measles becomes a disease of immunized persons."
Subtle DNA changes are connected to and the overuse of vaccines and consequentaly, autism.
