Vaccines

Overview

  • Do not memorize schedule

  • Understand how many vaccines they need and what to do if behind schedule

  • When in doubt: give vaccine

Active Vaccine

Antibody against antigens include:

  • organism pieces

  • toxins

  • toxoid: look like toxins (e.g. tetanus toxoid vaccine)

Passive Vaccine

Includes:

  • maternal to fetus

  • IVIG

Herd immunity

  • if enough people get vaccined in the community, disease disappears

Vaccine Reactions

Allergies

Egg Allergies

  • Do not give Yellow fever vaccine

    • Safe to give MMRV (MMR, varicella) vaccines

    • Safe to give Flu vaccines now

Vaccines contraindicated in cases of neomycin allergy include:

  • IPV

  • MMR

  • Varicella

  • Hepatitis A

The vaccines for rotavirus and meningococcus are contraindicated in cases of latex allergy.

Live attenuated

  • Immunocompromised: AIDS, transplants, biologics drugs (Etanercept), pregnant women

  • MMRV

  • Flu, intranasal

Normal Reaction

  • If temp < 104

  • Erythema

  • Consolable

Abnormal Reaction

  • temp > or = 104

  • Inconsolable

  • frank anaphylaxis

Scenarios

  • Sick: give vaccine

  • family history: give vaccine

  • autism: give vaccine

Individual Vaccines

Hep B

  • prevent vertical transmission via IVIG and hep B vaccine immediately (both within 12 hours)

  • mom -: start Hep B series

  • mom unknown: give hep B within 12 hours, test mom, if positive, give HBIG within 7 days

DTaP

  • DTaP: 5 doses. Big D = bigger dose

  • TdaP: 1 dose after 11, every 10 years

  • Td: booster, can be given instead of TdaP

HiB

  • Getting Hib does not give immunity

MMRV

Pneumococcal

  • mostly for adults

  • kids: if sickle cell or asplenic

Meningitis

  • every one gets, especially if shared space (college, military)

HPV

Hep A, B

Flu

Diseases shouldn't see

Tetanus

  • cause: dirty wound from rusty metal puncture

  • symptoms: lock jaw, spastic paralysis, die

  • diagnosis: clinical

  • treatment: intubate, sedate, muscle relaxers, paralytics, IV antibiotics (metronidazole)

  • prevention: Tdap, Td booster, tetanus IVIG

    • get 3 doses as adult (tdap, dtap, td, tt; 1 must be in adulthood), get every 10 years

  • dirty wound: metal, dirt, feces, soil, saliva

  • if more than 10 years since last dose: give tdap. Can also use Td

Diptheria

  • Symptoms: Fever; dysphasia, dyspnea from pseudomembrane (do not try to peel)

  • Diagnosis: clinical

  • Treatment: secure airway (intubate), anti-toxins,IV antibiotics

Pertussis

  • Symptoms: 3 phases

    • Catarrhal: nonspecific symptoms looks like cold, infectious

    • Paroxysmal: coughs followed by wheezing on inspiration (whooping cough)

    • Resolution:

  • Diagnosis: clinical

  • Treatment: supportive, erythromycin

Rotavirus

  • oral vaccine

  • CI in anyone with

    • intussuception

    • Immunodeficiencies such as SCID (live, attenuated vaccine)

    • latex allergies
