Vaccines and Autism Flashcards
What were the 2 debunked hypothesis about autism being caused by vaccines?
- MMR vaccine ( Measles, Mumps, and Rubella
- conducted by Dr. Wakefield - Vaccines in general cause autism
- Thimersoal
What were bebunking factors for the MMR vaccine?
around the same time children have the MMR vaccine, can see characteristics of Autism in children
What are 2 characteristics of children with Autism?
- Babies have no reaction to loud noise
2. Have no eye contact with objects in front oft them
What is Thiomersal?
- mercury based preservative
- added to multiple use vaccines to prevent bacterial and fungi growth
How was the hypothesis of “vaccines in general cause Autism” due to Thiomersal debunked?
- Ethy mercury (thiemesoal) takes 4 days for body to clear out. Methy mercury found in fish takes 44 day for the body to break down2
- CDC ( Center for Disease Control) removed Thimersol from vaccines and Autism rate still increased
What are 4 proposed hypothesis for the cause of Autism?
- gene inheritance o
- autoimmune disease that attacks brain cells
- accelerated brain development in the uterus
- pregnant females with inflammation
- a flu
What are two viruses and bacteria that cause cancer?
- HPV & HBV
- H. Pylori bacteria
Why is there more than shot given for inactivated vaccine?
weakened version of the pathogen that is injected into the body
Why there usually only 1 shot for attenuated vaccine?
- closet things to a natural infection triggers strong cellular response
- gives a lifelong immunity
What are the downsides of attenuated vaccine?
pathogen can revert back to virulent form and cause disease
What is an inactivated vaccine?
pulls parts of virus disables virus or disabled bacterium into vaccine
Why is the inactivated vaccine have more than 1 shot?
stimulate a weak immune system response b/c pathogen is disabled needs to have series of shots
What are 3 attenuated shots?
- mumps
- measles
- rubella
What are 2 inactivated shots?
- HPV
- HBV
How can some viruses cause cancer?
- can cause genetic changes in the cell that makes them more likely to be cancerous
- inject oncogene that can cause cancer
