1 Vaccines August 29, 2017

2 Bell Work What type of degree is earned at a community college and requires approximately 2 years to complete? How many years does a bachelor’s degree typically require? What type of program is earned at a college or university and is 2 years past a bachelor degree? What is the highest level degree possible and requires the most education? What type of immunity is a vaccine?

3 Papers Great Job! If you have questions about your grade, please me or see me after class. Review hierarchy of degrees

4 REVIEW Three Types of Immunity Stages of Disease

5 Stages of Disease Incubation stage Prodromal stage Acute stage
Declining stage Convalescent stage There are several stages in the disease process. In some illnesses, there are not clear definitions between the stages.

6 Immunity able to resist a particular disease especially through preventing development of pathogenic microorganism or by counteracting the effects of its products.  Protection from infectious disease Innate, Active and Passive Further categorized as acquired naturally or passively Immunity is defined as protection from infectious disease.

7 Innate Immunity Innate (Natural) Immunity:
It is the natural resistance components such as intact skin, salivary enzymes, and neutrophils, natural killer cells, which provide an initial response against infection that is present in an individual at birth prior to exposure to a pathogen or antigen.

8 Active Natural Immunity
Develops when body is exposed to pathogenic microorganisms Microorganisms contain antigens (cell markers) White blood cells develop antibodies Antibodies protect during second exposure An example of active natural immunity is when a person is infected with varicella. Varicella is the virus that causes chicken pox. The person gets sick, recovers, and never “catches” chicken pox again. The person had the disease and will never get this disease again due to the antibodies the person has.

9 Active Artificial Immunity
Develops when antigen is purposely introduced into body Vaccine Live, weakened, dead microorganism Stimulates antibody formation without causing disease Active artificial immunity occurs when a person receives a vaccine to produce immunity. An example includes the tetanus vaccine. After you receive the tetanus injection, you are protected against tetanus. The vaccine stimulated antibodies that will protect you from becoming ill.

10 Passive Natural Immunity
Develops when antibodies from mother cross placenta to fetus Provide protection to fetus for several months Additional antibodies are found in breastmilk Passive natural immunity occurs when a mother gives birth and the newborn does not get ill for a short period of time. Passive immunity is short term. Another example of passive natural immunity is when a mother breastfeeds her infant. The child receives the mother’s antibodies through breast milk and will not become ill.

11 Passive Artificial Immunity
Develops when preformed antibodies from animal or human are then injected into an individual with known exposure Antiserum provides temporary passive immunity Helps in cases of exposure to rabies, botulism, venomous snake or spider bites, hepatitis, and diphtheria Passive artificial immunity occurs when preformed antibodies are developed in an animal or human and are then injected into an individual with a known exposure. A person with a known exposure to hepatitis can be injected with gamma globulins to produce a short-term immunity to hepatitis A. The injection boosts the person’s immunity.

12 Standard Assess the differences between healthcare associated infections and non-healthcare associated infections using examples drawn from mock case studies. Support explanations with relevant surveillance statistics, preventive measures, and methodologies concerning outbreak detection, management, and education.

13 By the end of class, Students will be able to:
Objective By the end of class, Students will be able to: Understand why we vaccinate and be able to give examples of vaccinations available.

14 Vaccines Vaccination is one of the best ways parents can protect infants, children and teens from potentially harmful diseases. Vaccine-preventable diseases can be very serious, may require hospitalization, or even be deadly – especially in infants and young children.

15 Diseases for which vaccination is routinely recommended
Mumps Pertussis/Whopping Cough Pneumococcal disease Polio Rotavirus Rubella Tetanus Varicella (chickenpox) HPV Diphtheria Haemophilus influenzae type b (Hib) Hepatitis A Hepatitis B Herpes zoster (shingles) Human papillomavirus (HPV) Influenza Measles Meningococcal disease

18 Why vaccinate? The bottom line is that vaccines save lives According to a recent study led by the CDC, routine childhood vaccinations administered between 1994 and 2013 “will save 732,000 lives, prevent 322 million cases of illness and prevent 21 million hospitalizations, as well as save $1.38 trillion.”

19 Myth Most diseases are nonexistent in the United States, so there is no real need to getting vaccinated.

20 Many diseases ARE common in other parts of the world.
Travelers can bring diseases into the United States and disease can spread QUICKLY.

21 Myth Natural infection is better than vaccination.

22 There can be a high a price to pay for natural immunity:
Chickenpox infection can lead to pneumonia Polio infection can cause permanent paralysis Mumps infection can lead to deafness Hib infection an result in permanent brain damage

26 Haemophilus influenza (H
Haemophilus influenza (H. influenzae) is an invasive bacterial infection that is exclusively a human pathogen spread by airborne droplets through sneezing or coughing, or by direct contact with secretions or fomites. Invasive H. influenza type b (Hib) can cause severe illness, including meningitis and systemic, invasive disease in the bones and joints

42 Polio Poliomyelitis (polio) is a highly infectious viral disease, which mainly affects young children. The virus is transmitted by person-to-person spread mainly through the fecal-oral route or, less frequently, by a common vehicle (e.g. contaminated water or food) and multiplies in the intestine, from where it can invade the nervous system and can cause paralysis. Initial symptoms of polio include fever, fatigue, headache, vomiting, stiffness in the neck, and pain in the limbs. In a small proportion of cases, the disease causes paralysis, which is often permanent. There is no cure for polio, it can only be prevented by immunization.

45 Rotavirus Rotavirus is a contagious virus that can cause gastroenteritis (inflammation of the stomach and intestines). Symptoms include severe watery diarrhea, often with vomiting, fever, and abdominal pain. Infants and young children are most likely to get rotavirus disease. They can become severely dehydrated and need to be hospitalized and can even die

47 Rubella Rubella, sometimes called German measles or three-day measles, is a contagious disease caused by a virus. The infection is usually mild with fever and rash. Symptoms Rubella usually causes the following symptoms in children: Rash that starts on the face and spreads to the rest of the body Low fever (less than 101 degrees) These symptoms last 2 or 3 days. Older children and adults may also have swollen glands and symptoms like a cold before the rash appears. Aching joints occur in many cases, especially among young women. About half of the people who get rubella do not have symptoms. Complications Birth defects if acquired by a pregnant woman: deafness, cataracts, heart defects, mental retardation, and liver and spleen damage (at least a 20% chance of damage to the fetus if a woman is infected early in pregnancy) Transmission Spread by contact with an infected person, through coughing and sneezing

50 Tetanus Tetanus is an infection caused by bacteria called Clostridium tetani. When the bacteria invade the body, they produce a poison (toxin) that causes painful muscle contractions Another name for tetanus is "lockjaw" because it often causes a person's neck and jaw muscles to lock, making it hard to open the mouth or swallow. We are protected through the dTap vaccine

53 Varicella Chickenpox is a very contagious disease caused by the varicella- zoster virus (VZV). It causes a blister-like rash, itching, tiredness, and fever. Chickenpox can be serious, especially in babies, adults, and people with weakened immune systems. It spreads easily from infected people to others who have never had chickenpox or received the chickenpox vaccine. Chickenpox spreads in the air through coughing or sneezing. It can also be spread by touching or breathing in the virus particles that come from chickenpox blisters.

56 Human Papillomavirus (HPV):
HPV is the most common sexually transmitted infection in the United States. Approximately 20 million people are currently infected with HPV. At least 50% of sexually active men and women acquire genital HPV infection at some point in their lives. Persistent infection with high-risk types of HPV is associated with almost all cervical cancers. It is also possible to have an active infection without any signs or symptoms Photo courtesy of the Centers for Disease Control and Prevention (CDC)
