The Philippine Obstetrical and Gynecological Society (POGS) has a clinical practice guideline on Immunization for Filipino Women. Foremost is the recommendation on immunization for tetanus-diptheria, influenza and hepatitis B during pregnancy, and immunization with MMR and Varicella before discharge which has yet to be implemented. Lecturing to third year medical students, I hope that they may be encouraged to include immunzation in their clinical practice to eliminate vaccine-preventable diseases.

3. General Considerations for
Vaccination
• Never administer vaccines in the
buttock.
• Confirm completion of childhood (or
more recent) primary vaccine series
for measles, mumps, rubella (MMR)
and tetanus-diptheria (Td) before
initiating adult recommended
vaccine schedules.
@helenvmadamba
4. General Considerations for
Vaccination
• Maintain vaccine administration
record in patient’s chart, including
date, site and route of
administration, manufacturer and
lot number of vaccine.
@helenvmadamba
5. General Considerations for
Vaccination
• Knowing the route of vaccine
administration, needle size, and
vaccine storage and handling are
critical components of a quality,
office-based vaccine program.
@helenvmadamba
6. General Considerations for
Vaccination
• Simultaneous use of any vaccines is
not contraindicated.
• Antibiotic therapy or breastfeeding
are not contraindications to
vaccination. Likewise, the presence
of a pregnant woman or
immunosuppressed person in the
household is not a reason to withold
an indicated vaccine to a family
member.
@helenvmadamba
7. General Contraindications to
Vaccination
• Severe allergy to vaccine
components.
• Pregnancy (or if planning pregnancy
within four weeks) for live
attenuated vaccines.
• Severe immune attenuation (for live
attenuated vaccines only) –
consultation with infectious disease
specialist is advised.
@helenvmadamba
8. General Contraindications to
Vaccination
• Moderate or severe acute illness.
• If a live attenuated vaccine is given
simultaneously with another
vaccine, a four week separation
interval should be used between
vaccinations.
