IMMUNIZATION
•Immunization???
•Reduce mortality and morbidity
of mathernal and baby
 Rubella infection in pregnancy is
likely to cause fetal infection, which
can result in miscarriage, fetal
demise, and serious birth defects
(e.g., cataracts, heart disease,
deafness, intellectual disability).
 Influenza infection increases the risk
of serious complications in pregnant
women and their newborns, as well
as the risk of premature labor and
delivery.
 Reduced tetanus toxoid, diphtheria toxoid, and acel-lular
pertussis (Tdap) vaccine should be provided during each
pregnancy
 Preferably between 27 and 36 weeks of gestation. This timing
recommendation is based on the maternal immune response,
which peaks two weeks after administration.
• If not given during pregnancy
(and for the protection of the
newborn), The Tdap vaccine
should be administered
immediately postpartum in any
woman who has not previously
received it.
• If Tdap vaccination history cannot
be confirmed through written
records, the patient should be
considered unvaccinated and
should receive a Tdap vaccine.
 63% received Tdap in the first trimester and 37% after.
Tdap was given most commonly as wound prophylaxis.
 The incidence of spontaneous or elective abortion was no
greater in Tdap cases
 There were no significant differences in preterm delivery,
gestational age, or birth weight between groups.
 One or more congenital anomaly was identified
• The influenza vaccine is safe
in pregnancy, vaccinating all
pregnant women during any
trimester should be a
priority to minimize these
risks.
• They will be pregnant during
the flu season (or up to 3
months postpartum during
flu season).
• Although the effects of varicella virus on the
fetus are unknown, there are theoretical
concerns, and the risk of severe varicella virus
infection may be higher in pregnant women.
Therefore, vaccinating nonimmune women
before pregnancy is recommended.
 The hepatitis B vaccine has not been shown to cause any harm to the
developing fetus.
 The hepatitis B vaccine should be provided to any pregnant woman at
higher risk of exposure to hepatitis B (e.g., multiple sex partners,
recent injection drug use).
 Adequate safety data do not exist for the hepatitis A vaccine, but the
theoretical risks are low because it is produced from an inactivated
virus. Women who are thought to be at high risk of exposure to
hepatitis A should be considered for vaccination during pregnancy
(e.g., travel to endemic countries, chronic liver disease).
• Human papillomavirus (HPV) and herpes
zoster vaccines are not recommended
because of a lack of safety data in pregnant
women
• Immunization Live virus vaccines must be
avoided during pregnancy because of possible
effects on the fetus.
• These include measles, mumps,rubella
(MMR), yellow fever (YF-Vax), and varicella
(Varivax) vaccinations.
• The risks to the fetus from the administration
of rabies vaccine (RabAvert, IMOVAX) are
unknown.
Side effects

Immediate/early effects include fainting
and vasovagal reactions. These are
differentiated from anaphylactic shock
(see below). Patients who have received
the vaccine should be kept in the waiting
room for observation for 5 to 10 minutes
Local effects are mild and are the most
common such as soreness, erythema, and
swelling.
Systemic effects are less common and
include malaise and fever.

Mild allergic reactions can also occur.
In general, these will be in reaction to
exposure to avian proteins (eggs, such
as in yellow fever) or to traces of
neomycin/streptomycin (MMR).
Anaphylactic reactions are
exceedingly rare. They should be
recognized immediately and treated
following local protocolswith injection
of SC epinephrine (1:1000).
Long-termcomplications such as
Guillain-Barre syndrome can occur
but usually at rates lower than that
seen for spontaneous disease.
The items on this list DO NOT represent contraindications to immunization
1. Mild acute illness with or without low-grade fever
2. Autoimmune disorder, multiple sclerosis
3. Family history of convulsions, epilepsy
4. Recent exposure to an infectious disease
5. Current antimicrobial therapy or convalescence from recent illness
6. Prior reaction to immunization with mild/moderate tenderness, redness,
swelling, or fever of less than 40 °C
7. Personal history of allergies, excluding anaphylaxis, to
neomycin/streptomycin or egg protein
8. Family history of adverse reaction or allergies to vaccines
9. Positive TB skin test
