Immunization

Immunity:

The ability to destroy a particular antigen, it is may be inherited (natural) or acquired (artificial).

Natural immunity:

Resistance to infection or toxicity.

Acquired immunity:

Exposure to invading agents, either from bacteria, virus, or toxin.

Active immunity:

Production of antibodies against specific antigens, either naturally by having a disease or artificially by introducing the antigen in the body.

Passive immunity:

Temporary immunity by transfusing (immunoglobulin or antitoxin) artificially either from serum of human or animal, or naturally from mother to fetus by placenta.


Immunization

Antibody:

A protein found in serum formed from exposure to antigen.

Antigen:

Foreign substances (bacteria, virus, toxin, foreign protein) stimulate antibodies formation.

Immunization:

The process of inducing active or passive immunity artificially by administering an immunobiologic.

Immunobiologic:

Antigen substances (vaccine or toxoid) or antibodies containing preparation (globulins or antitoxoid) from human or animal, used for active or passive immunization.

Vaccination:

Inoculation with vaccina small pox virus to make a person immunity to small pox.


Immunization

Vaccine:

A suspension of live (attenuated) or inactivated or fraction of microorganisms administered to induced immunity.

Attenuate:

Reduce virulence (infectiousness) organism by treating it with heat or chemical it on certain media.

Toxoid:

Modified bacterial toxin that has been not toxic but has the ability to stimulate antitoxin formation.

Antitoxin:

A solution of antibodies from animals` serum immunized with antigen (passive immunity).

Immune globulin:

A solution of antibodies from humans` blood plasma (passive immunity & immunodeficiency person).


What are some complications of vaccinations mild reactions

What Are Some Complications ofVaccinations?Mild Reactions:

  • Inject able vaccines can cause localized pain,

  • redness and swelling at the site of the injection.

  • Fevers usually go away in 1-2 days.

  • Fussiness

  • Tiredness

  • Loss of appetite

  • Drowsiness

  • Mild, temporary vomiting or diarrhea within the

  • first week of getting rotavirus.


Serious complications

Serious Complications:

  • Serious allergic reactions or anaphylaxis – extremely rare; occur within a few minutes to a few hours after the shot.

  • Long-term seizures, coma, lowered consciousness, and permanent brain damage after DTaP– very rare

  • Guillain Barre Syndrome –vaccines containing the tetanus toxoid (DTaP, Td,Tdap), mengicoccal vaccine – paralysis – very rare


Precautions

Precautions

  • Severe or Moderately Severe Illness – wait until the child

    is better

  • Pregnancy or Possibility of Pregnancy – contraindicated

    live vaccines like Varivax, MMR, LAIV

  • Immunocompromised Persons – with AIDS, those on

    prolonged steroids, those on chemotherapy, those with

    cancer, those with agammaglobulinemia or other defects

    of immunity – discuss with provider.

  • Past History of Moderate to Severe Reactions to

    Vaccines or Any of Its Components

  • Past History of Intussusceptions - on the infant about to

    get Rotavirus
