Vaccinations work by exposing patients to antigens from pathogens which induces protective immunity. There are two main types of meningococcal vaccines - the meningococcal polysaccharide vaccine (MPSV) approved for those over 2 years old, and the meningococcal conjugate vaccine (MCV) approved for those 2 to 55 years old. The MCV is routinely recommended for adolescents, college freshmen living in dorms, and adults at increased risk, while the MPSV is only recommended for those over 56 at increased risk. Contraindications include severe allergic reactions or moderate to severe acute illness.

2. It's clear that prevention will
never be sufficient. That's
why we need a vaccine that
will be safe.

3. Definition
 Administration of preparations of microbial
antigen ,often combined with adjuvant ,to
induce protective immunity against microbial
infections.

4. How does vaccination work?
 Expose the patient to an Antigen
 A live or inactivated substance
(e.g., protein, polysaccharide) derived from a
pathogen (e.g bacteria or virus) capable of
producing an immune response.

7. MENINGOCOCCAL VACCINATION:
 Meningococcal Polysaccharide
Vaccine (MPSV).
 Meningococcal Conjugate
Vaccine (MCV).

8. MENINGOCOCCAL POLYSACCHARIDE
VACCINE (AMPSV)
 Approved for persons 2 years of age and older
 Administered by subcutaneous injection
MPSV Recommendations:
 Not recommended for routine vaccination of
civilians.
 Should be used only for persons at increased risk
of infection who are 56 years of age or older, or if
meningococcal conjugate vaccine is not available.

9. MENINGOCOCCAL CONJUGATE
VACCINE (MCV)
 approved for persons 2 through 55 years of age.
 Administered by intramuscular injection.
MCV Recommendations:
 Meningococcal vaccination is routinely recommended for :
 Adolescents.
 college freshmen who live in a dormitory.
 adults at increased risk of infection .

10. MENINGOCOCCAL VACCINE
CONTRAINDICATIONS
 Severe allergic reaction to a vaccine component or
following a prior dose.
 Moderate or severe acute illness.
