immunizations
Giving a child multiple vaccinations for different diseases at the same time increases the risk of harmful side effects and can overload the immune system.
-not necessarily true -research has indicated this is safe
Monosodium glutamate (MSG) :
used as stabilizer to help the vaccine remain unchanged when the vaccine is exposed
measles post exposure prophylaxis: within 72 hours? within 6 days?
w/in 72 hours-vaccine; IG w/in 6 days
Vaccine risks: MMR- DTaP-
- MMR = encephalitis 1 in 1,000,000 - DTaP = crying with recovery - 1 in 1000 convulsions with full recovery - 1 in 14,000 encephalitis- 0-10.5 in 1,000,000 death - none

4
Diptheria dosing schedule for children?
5 doses - 2 months - 4 months - 6 months - 15 months - 4-6 yo
Vaccine
A product that produces immunity therefore protecting the body from the disease. Vaccines are administered through needle injections, by mouth and by aerosol
Immunization Rates for Adolescents/ Teens (13-17 yrs)
BEST WITH KIDS.... then they taper off
Anthrax
Bacteria found in soil and animals Inhalation/contact of spores ; ingestion
Inactivated Vaccine and 2 examples
Bacteria or virus isolated Pathogen inactivated using heat or chemicals Inactivated pathogen injected Immune response evoked Inactivated viruses or bacteria cannot cause infection, but do stimulate B cells to produce antibodies. Several doses or booster shots are typically required to create an effective immune response. ex: Polio, Hepatitis A
Subunit/Conjugate Vaccines and 2 examples
Complete virus or bacteria selected Part of pathogen that evokes immune response is isolated Part of pathogen is presented or used to create a recombinant vaccine (perhaps attached to a carrier) Vaccine injected Immune response is evoked ex:Haemophilus Influenzae (Hib) Pertussis
disease risk: rubella
Congenital Rubella Syndrome: 1 in 4 (if woman becomes infected early in pregnancy)
vaccine risk: DTap
Continuous crying, then full recovery: 1 in 1000 Convulsions or shock, then full recovery: 1 in 14,000 Acute encephalopathy: 0-10.5 in 1,000,000 Death: None proven

Passive Artificial Immunity
Immune Globulin or disease specific globulins - antibodies in a serum injected. Human or animal products. Protection 1-2 months Preformed Antibodies
Active Artificial Immunity
Immunization: Altered disease antigen introduced and body makes antibodies against antigen
Measles - Reporting?
Healthcare workers must report suspected measles to health department within 24 hours
healthcare workers (6)
Hepatitis B: If you don't have serologic evidence of immunity; 3-dose series (dose #1 now, #2 in 1 month, #3 approx. 5 months after dose 2) Tdap: HCP, regardless of age, should receive a single dose of Tdap if they have not previously received Tdap and regardless of the time since last Td dose; Td booster every 10 years Influenza:-All HCP MMR:- Born 1957 or later and not had MMR or no serologic immunity Varicella (chickenpox): If no serologic evidence of immunity; 2 doses, 4 weeks apart Meningococcal: If routinely exposed to N. meningitidis
Herd Immunization
Herd immunity is resistance of spread of infection in community because there are few people susceptible to the infection. CDC goal is 95% vaccination rates. Herd immunity can fail if < 95% rates
why do infants need multiple vaccines?
Infants unable to produce high levels of antibodies. need an active immune system
Anthrax S/S
Inhalation s/s: fever, chills, chest pain, confusion, cough, sweat, headaches GI s/s: swelling, sore throat, painful swallowing, bloody diarrhea, pain Injection: blisters, painless skin sores (black center), swelling, abscesses
vaccination

measles Tx
Isolation Supportive Care
Tetanus Treatment-
Medical emergency: Hospitalization -Immediate human tetanus immune-globulin (TIG) or equine antitoxin -Tetanus vaccine -Drugs to control muscle spasm -Aggressive wound care -Antibiotics -Supportive care (intubation may be needed)
Passive Natural Immunity
Maternal-infant Transmission: Infant acquires antibodies from mother. Short livespan of antibodies leaves infant unprotected @ 2-3 months
Sufficient antibody titer needed to
PREVENT DISEASE Vary by vaccine May need multiple doses Individuals vary in mounting a response to vaccine - check titers to determine if person is immune
disease risk: pertussis
Pneumonia: 1 in 8 Encephalitis: 1 in 20 Death: 1 in 1,500
Side effect of measles disease

Live Attenuated Vaccine and 2 examples
Virus is isolated, grown in culture Weakened strain of virus extracted, purified Live weakened strain is injected Immune response evoked by stimulating both memory B and memory T cells. Humans can often gain long-term immunity from an attenuated vaccines after just one or two doses Produces infection without symptoms ex: Measles, mump and rubella (MMR) Varicella (chicken pox)

Thimerosal
is a mercury-containing preservative that is added to vials of vaccine that contain more than one dose to prevent contamination and growth of potentially harmful bacteria. - thought to be linked to autism
Egg protein
is found in influenza and yellow fever vaccines, which are prepared using chicken eggs.
Formaldehyde
is used to inactivate bacterial products for toxoid vaccines, (these are vaccines that use an inactive bacterial toxin to produce immunity.) It is also used to kill unwanted viruses and bacteria that might contaminate the vaccine during production. Most formaldehyde is removed from the vaccine before it is packaged.

Antibiotics :
to prevent the growth of germs (bacteria) during production and storage of the vaccine. No vaccine produced in the United States contains penicillin.
Aluminum gels or salts:
which are added as adjuvants to help the vaccine stimulate a better response.
