Immunizations Childhood and Adolescent Jan Bazner-Chandler CPNP, MSN, CNS, RN

What Immunization Is  Immunization is the process by which a subject is rendered immune or resistant to a specific disease  Natural exposure – contact with the agent  Artificial exposure – parts of the infectious agent or inactivated version is given for the purpose of becoming immune to the disease agent it causes.

Childhood Immunization  Childhood immunization schedule American Academy of Pediatrics   Download children age  Download children age American Academy of Pediatrics: protect tomorrow initiative:

Hepatitis B (HepB) Vaccine  All infants should receive the first dose soon after birth or before hospital discharge.  Second dose should be given at least 4 weeks after the first  Third dose 16 weeks after the first dose and at least 8 weeks after the second dose  Infants born of HBsAg-postive mothers should receive first immunization within 12 hours of birth as well as HBIG.

Diphtheria, Tetanus, Acellular Pertussis  DTaP  Given at 2, 4 and 6 months  4 th dose between 15 and 18 months  Last DTaP at the 4-6 year pre-K check up  1 st Tdap at age years or at least 5 years from last DTap  Tetanus every 10 years after that

Cocooning  New term for 2010  Strategy to protect the newborn up to 6 month old from pertussis or “whooping cough”  Booster available for adults Tdap  The goal to immunize all adults who interact with infants to prevent pertussis

Polio  Injection form given at 2 months, 4 months after 6 months and at kindergarten check-up  Oral not given due to shedding virus in stool

Haemophilus Influenza Type b  Hib  Given at ages 2 and 4 months and 12 months  Any child entering child care or pre-kindergarten under age 5 years in California are required to have Hib.  Not a standard immunization for children born outside the USA

Why?  Haemophilus influenzae type B (Hib) disease is a serious disease caused by bacteria. It usually strikes children under 5 years of age.  Leading cause of bacterial meningitis in children under 5 years  Pneumonia  Epiglottitis – severe swelling of epiglottis – resulting in death for obstruction of breathing  Before Hib immunization 20,000 children per year had the infectious disease with 1000 deaths per year.

Measles, Mumps, Rubella  MMR  Two doses:  1 st 12 months or older  2 nd dose kindergarten visit  If no record of second dose it should be given at 11 to 12 year old visit  May develop a rash a week to ten days after immunization  Not immunized against wild strain – exposure would bring milder case

Mumps outbreak  2010 in New York 1500 Orthodox Jews over had case of mumps during a 7 month period.  One un-immunized child at camp from England spread the disease.  Why a problem?  Complications  Hearing loss  Testicle swelling - infertility

Varicella  Chicken pox – recommended at 12 – 15 months and second dose at 4-6 years or kindergarten visit  Un-immunized children over 13 years would receive two doses at least 4 weeks apart

Varicella  Contraindication: allergy to immunization, pregnancy or possibility of pregnancy within 4 wks  Children on high dos immunosuppressive therapy or immunocompromised HIV / AIDS – vaccination can be given if CD4 T-lymphocyte percentages or 15% or greater.  Precautions:  if blood, plasma or immune globulin given within the past 11 months.  Antiviral drugs 24 hours before or 14 days after immunization

True Contraindications  True allergic response  Rash or hives after previous vaccination  Allergy to eggs or egg products should not be given influenza vaccination

Reactions to Immunizations  Fever greater than 103, shock or collapse, or inconsolable crying for greater than 3 hours. (DTaP)  Low grade fever, fussiness, and soreness at injection site are not reasons to prevent further vaccinations  Mild rash or fever may occur 10 days to 2 weeks after MMR or Varicella

Interventions  Tylenol every 4 hours for fussiness or low grade fever  Warm bath  NO ASPIRIN  NO Motrin for infants under 6 months of age  AAP recommends Tylenol for all ages due to confusion in dosing.

L.A. Unified Recommendations  Complete health and immunization record  All new students must have written results of a PPD test for tuberculosis within 12 months  If PPD is positive a chest x-ray is recommended  Treatment is recommended unless the child has some immune suppressed condition.

PPD Waiver  I hear by request exemption of the child from the tuberculosis assessment requirement for school / childcare entry because this is contrary to my beliefs. I understand that should there be cause to believe that my child is infected with active TB or should there be a tuberculosis outbreak, my child may be temporarily excluded from school.

Pre-school and Child Care  Pre-kindergarteners must be immunized against Haemophilus influenza type B or Hib.  This is not a standard immunization for children born outside the United States  Hib would not be required for a child over 5 years of age.

Communicable Diseases  Chicken pox (varicella)  Measles (Rubeola)  Pertussis (Whooping Cough)  Rubella (German Measles)  Scarlet Fever  Mumps

Varicella  Agent: varicella zoster virus  Incubation: 10 – 14 days  Transmission: respiratory  Period of communicability: 2 days before eruption of vesicles until lesions crusted.  Prodromal phase: slight fever, malaise, pruritic rash; macular to papular to vesicular.

Varicella

 Communicability: children who have “chicken-pox” are infectious for two days before the vesicles erupt until all vesicles are crusted over (about 5 days).

Management of Varicella  Isolation  Skin care: tepid bath, calamine lotion, clip finger nails.  Keep from scratching  Antihistamines for itching - Benadryl  No ASA (salicylate containing products) – acetaminophen only.  Varicella vaccine now available.

Reyes Syndrome  Almost always preceded by a viral illness, URI, Flu, chickenpox  Linked to the use of aspirin or aspirin containing medications (salicylates)  Assessment  Persistent vomiting  Lethargy or sleepiness  Confusion, irrational or combative behavior  Seizures to coma

Measles or Rubeola  Agent: Virus  Transmission: respiratory, blood and urine  Incubation period: 10 to 20 days  Period of Communicability: 4 days before and 5 days after rash appears.  Prodromal stage: fever, cough, conjunctivitis, Koplik spots.

Blotchy rash starts on forehead

Measles Conjunctivitis

Koplik’s Spots on Palate

Rubella or German Measles  Agent: Rubella virus  Source: nasopharyngeal secretions; secretions in blood, stool, and urine.  Transmission: direct contact.  Incubation period: 14 to 21 days  Period of communicability: 7 days before to 5 days after appearance of rash.

Rubella  Rash first appears on face and rapidly spreads downward  Isolate from pregnant women  TORCH – affects fetus

Mumps In mumps the parotid glands swell and obscure the angle of the jaw.

Mumps  Disease caused by a virus that spreads through saliva and infects many parts of the body especially the parotid salivary gland.  Incidence has decreased to about 1,000 per year.  Two potential complications: encephalitis and orchitis (inflammation of testicle)

Pertussis (Whooping Cough)  Agent: Bordetella Pertussis  Source: Respiratory  Transmission: droplet spread or contact with contaminated article.  Incubation period: 10 days  Period of communicability: before onset of paroxysms to 4 weeks after onset.

Interventions  Erythromycin for the child and all contacts  Very dangerous for the neonate – most often the contact is an adult with a chronic cough  May led to hospital admission – ventilator assist

Fifth Disease  Fifth disease is a mild childhood illness caused by the human parvovirus B19 that causes flu-like symptoms and a rash. It is called fifth disease because it was fifth on a list of common childhood illnesses that are accompanied by a rash, including measles, rubella (or German measles), scarlet fever (or scarlatina), and scarlatinella, a variant of scarlet fever.

Fifth Disease  Primarily seen in school-age children between ages 5 and 14 years.  Causes a reddish rash on the child’s face that looks as if the child has been slapped.

Fifth Disease Symptoms  Starts as a vague illness.  Fever, nasal congestion, sore throat, fatigue, muscle aches and headache.  7-10 days later the facial rash appears (slapped cheeks rash).  Light pink rash on arms and spreads to the trunk in a lacelike pattern.
