Transcript

  • 1. The Importance of Immunization By: Misty Moser ADNS and Cynthia Hill ADNS
  • 2. What is a Vaccine? A substance used to stimulate the production of antibodies and provide immunity against one or several diseases (Merriam-Webster)
  • 3. Basically, a vaccine is a substance used to prevent the spread of disease, usually using a killed or weakened form of the disease.
  • 4. How Do Vaccines Work? <ul><li>First, a little about the immune system: </li><ul><ul><li>Antigens </li><ul><li>These are foreign invaders, such as bacteria, that enter the body </li></ul><li>Antibodies </li><ul><li>When the immune system detects the antigens, it begins to produce protein substances called antibodies to fight the antigens. </li></ul><li>Memory Cells </li><ul><li>Are produced and help the immune system to activate much faster.
  • 5. These cells have a long life span and the ability to remember intruders.
  • 6. These are stockpiled so they are available to fight off the disease should you be exposed again. </li></ul></ul></ul></ul>
  • 7. How Do Vaccines Work? <ul><li>So... </li><ul><ul><li>The vaccine introduces a weakened or dead form of the antigen, or foreign invader.
  • 8. The antigen isn't strong enough to produce symptoms, but is strong enough for the immune system to produce antibodies.
  • 9. The immune system then stock piles these antibodies for future defense.
  • 10. Now it's armed and ready should it be exposed to the disease. </li></ul></ul></ul>

  • 12. Spreading the Disease!!! <ul><li>You can be contagious BEFORE you have any signs or symptoms of the disease!
  • 13. Some diseases, such as tetanus, are not spread from person to person, but are found in the dirt! </li></ul>
  • 14. Safety of Vaccination Risk vs Benefit
  • 15. <ul><li>Risk </li><ul><li>Side Effects </li><ul><li>Pain at injection site, muscle aches, rash, fever are normal and should not cause alarm. </li><ul><li>“ Nearly 90% of adverse events following vaccinations are categorized as non-serious.” (CDC) </li></ul><li>Rare serious side effects </li><ul><li>Most are allergic reactions to ingredients and not reactions to the antigen </li></ul></ul></ul></ul><ul><li>Benefits </li><ul><li>Prevention of deadly and debilitating diseases.
  • 16. Keeps child from suffering through a preventable illness.
  • 17. Saves money </li><ul><li>Less doctor visits
  • 18. No hospitalization
  • 19. Less time off work </li></ul><li>Herd Immunity </li><ul><li>Those who are vaccinated keep it from spreading. </li></ul></ul></ul>
  • 20. Herd Immunity “ When a critical portion of a community is immunized against a contagious disease, most members of the community are protected against that disease because there is little opportunity for an outbreak.” - NIAID
  • 21. Credit: NIAID http://www.niaid.nih.gov/SiteCollectionImages/topics/communityImmunityGeneric.gif
  • 22. Testing and Monitoring <ul><li>Before vaccines are licensed, the FDA requires testing to ensure safety.
  • 23. Once a vaccine is in use, the FDA and CDC monitor it's adverse events </li><ul><li>Vaccine Adverse Event Reporting System or VAERS </li><ul><li>If an adverse reaction is experienced, it can be reported to VAERS, any hint of a problem with the vaccine prompts further investigation by the CDC and FDA </li><ul><li>Research will be performed to investigate the vaccine and see what action needs to be taken </li></ul></ul></ul></ul>
  • 24. Controversy It is true vaccines are not 100% effective...
  • 25. Mumps out break in NY and NJ in 2009 77% of those who contracted it were immunized!!!
  • 26. But wait! <ul><li>Let's look at the math... </li><ul><li>For example, if we have... </li><ul><li>Population of 1,000 people </li><ul><li>According to the World Health Organization 95% of people are vaccinated </li><ul><li>So... </li><ul><li>950 people vaccinated
  • 27. 50 people not vaccinated </li></ul></ul><li>Out of this 1,000 total population </li><ul><li>100 people contract mumps </li><ul><li>77 vaccinated contracted it
  • 28. 23 unvaccinated contracted it </li></ul></ul></ul></ul></ul></ul>
  • 29. The Population as a Whole <ul><li>Immunized Population (950 people) </li><ul><li>Only 77 contracted mumps </li><ul><li>That's about 8% of those immunized </li></ul></ul><li>Unimmunized Population (50 people) </li><ul><li>23 contracted mumps </li><ul><li>That 46% of that part of the population!!!! </li></ul></ul></ul>
  • 30. Let's Put it in Perspective <ul><li>Taking that same 1,000 people, imagine it the other way around... </li><ul><li>950 unimmunized (95%) </li><ul><li>437 people would get the mumps </li></ul><li>50 immunized (5%) </li><ul><li>4 would get the mumps </li></ul></ul></ul>
  • 31. Vaccines and Autism <ul><li>Two different types of Mercury </li><ul><li>Methylmercury </li><ul><li>Found in fish
  • 32. Tends to accumulate in the body
  • 33. Is tied to developmental delays and neurological impairment in babies </li></ul><li>Ethylmercury </li><ul><li>Does not accumulate in the body
  • 34. Was used in vaccines as a preservative to prevent bacterial and fungal contamination </li><ul><li>However, mandated by the FDA to be removed from all vaccines, except the flu vaccine </li><ul><li>Vaccines must be free of ethylmercury or only contain trace amounts (less that one microgram). </li></ul></ul><li>Despite removal, autism rates continue to climb. </li></ul></ul></ul>
  • 35. Why Get Vaccinated? The Importance of Immunization
  • 36. Communicable Diseases <ul><li>Measle, Mumps, Rubella - MMR
  • 37. Chicken Pox - Varicella
  • 38. Diptheria, Tetanus, Pertussis (aka Whooping Cough) - DtaP
  • 39. Hepatitis (A and B) – HepA, HepB
  • 40. Polio – IPV
  • 41. Rotavirus – RV
  • 42. Pneumoccocal – PCV
  • 43. Haemophilus influenzae B- Hib </li></ul>

  • 48. If Everyone Else is Doing It, Why Should I? <ul><li>Won't herd immunity protect me anyway? </li><ul><li>Technically, yes it does help the community as a whole </li><ul><li>But what if everyone thought this way? Then no one would be immunized
  • 49. Risk of exposure to those who also think this way and don't get vaccinated </li></ul><li>Not everyone can get vaccinated </li><ul><li>Exposure to those who aren't </li></ul></ul></ul>
  • 50. “ An ounce of prevention...” <ul><li>PREVENTION!!! </li><ul><li>This is the key to public health
  • 51. Disease is easier to prevent than treat </li><ul><li>“ An ounce of prevention is worth a pound of cure.” - Ben Franklin </li></ul></ul></ul>
