BIOL 2050 1st Edition Lecture 3Outline of Last Lecture II. Continuation on Radioactive IsotopesIII. Energy Levels of Electronsa. Electron Distribution and Chemical Propertiesb. OrbitalsOutline of Current Lecture IV. Vaccinesa. Herd ImmunityV. PolioCurrent LectureVaccines I. Examples of diseases that vaccines protect againsta. Bacterial Meningitis: bacterial infection of the membranes of the brain and spinal cord.b. Whooping Cough (Pertussis)Herd ImmunityI. Herd Immunity is when enough people (80-90%) are vaccinated against a contagious illness and that causes most of the community to be protected. This includes those who cannot be vaccinated.II. Herd Immunity has been compromised due to lack of immunizations.a. Outbreaks of Whooping Cough have become more and more common.III. Who is more susceptible?a. The elderly: immunizations wear off with age so the elderly are in danger of catching diseases.b. Infants: low immune system. Infants can only take so many vaccinations at a time in order to avoid overloading their immune system.c. Compromised Immune Systems: Those with compromised immune systems are unable to be vaccinated and are more susceptible to diseases.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.IV. Diseases can cause death or neurological problems that persist after the disease is treated. V. Why are parents not vaccinating their children?a. False study done in the 90s that suggested that vaccines led to autism.This study was retracted due to falsified evidence, but parents still fear for their children.PolioI. First major issue where vaccinations made a differenceII. Vaccines don’t cure but they preventIII. People don’t get immunized for polio because they weren’t witnesses of the diseaseIV. Polio targets the neurotransmitters that control motor functionV. Polio can take months to recover and can cause long term paralysis VI. In 1952 there were 52,000 new cases mostly targeting children in the summer
