Study Notes
Vaccines
- Vaccines work by introducing a harmless form of a virus into the body, triggering an immune response that creates "memory" cells capable of fighting off future infections.
- Vaccines contain viral proteins, not genetic material, so they cannot cause the disease.
- Natural immunity occurs when the body is exposed to a virus, creating an immune response similar to a vaccine.
Vaccine Safety
- Before the development of vaccines, many children died from diseases like smallpox, diphtheria, whooping cough, and polio.
- Concerns about vaccine safety arose after studies, like the Wakefield Study, suggested a link between vaccines and autism.
- The Wakefield Study was highly flawed and its findings have been widely debunked.
- The CDC found no correlation between the MMR vaccine and autism.
- More awareness and increased screening have led to an apparent increase in autism diagnoses, but the underlying cause remains complex and not fully understood.
Evaluating Scientific Claims
- Scientific claims are statements about the natural world that can be tested using the scientific method.
- Pseudoscience is presented as scientific, but lacks evidence and is not supported by the scientific method.
- To evaluate scientific claims, consider the credibility of the source, their credentials, and any potential biases.
- Primary literature includes peer-reviewed publications with original research data, while secondary literature provides summaries or reviews of scientific findings.
- Social media is not a reliable source of scientific information due to a lack of credentials and peer review.
- Anecdotal evidence, based on personal experiences, is often unreliable and should not be taken as scientific evidence.
Correlation vs. Causation
- Correlation refers to a relationship between two events or phenomena, but it does not mean one causes the other.
- Causation occurs when one event directly leads to another.
- It is essential to distinguish between correlation and causation when evaluating scientific claims.
Herd Immunity
- Herd immunity occurs when a significant portion of a population is vaccinated, protecting those who are vulnerable or unable to be vaccinated.
- Vaccinating a large number of people reduces the spread of disease by limiting the virus's circulation.
- Choosing not to vaccinate children puts them at risk and could potentially lead to outbreaks affecting the entire community.
