placenta, providing passive immunity to the newborn child1,2

ACOG1
• Obstetric care providers should administer the tetanus toxoid, reduced diphtheria toxoid,
and acellular pertussis (Tdap) vaccine to all pregnant patients during each pregnancy, as
early in the 27-36-weeks-of-gestation window as possible
FOGSI2,3
• 2 doses of TD at least 28 days apart commencing from 2nd trimester
• Tdap vaccination can be considered instead of the 2nd dose of TD
• Tdap should be administered during pregnancy in order to provide optimal
protection to the baby during its first months of life. (Strength of recommendation:
A; quality of evidence IV)
Influenza
ACOG⁴
• All women who are or might be pregnant or post-partum during influenza season should
receive an influenza vaccination.
• Any of the licensed, recommended, age appropriate, inactivated influenza vaccine can be
given at any time during pregnancy
FOGSI⁵
• Influenza vaccine is recommended to all pregnant women from 26 weeks
onwards
(Strength of recommendation: A; quality of evidence III)
• In case of a pandemic the influenza vaccine can be given earlier to
protect the mother

• Pertussis is more commonly known as ‘whooping cough’1
• Pertussis is a highly contagious respiratory infection caused by
the Gram-negative bacterium Bordetella pertussis1,2
• Pertussis transmission: airborne droplets or direct contact with
nasopharyngeal discharges from an infected person1,3
• In an immune-naïve population, 1 primary case of pertussis can
cause ~12-17 new cases4,5
• Pertussis affects people of all ages3

1st dose of DTP vaccine is not recommended until 6–8 weeks of age
Infants are not protected during the
first 2 months of life2
Rationale for pertussis vaccination during pregnancy
Vaccination for neonatal protection should ideally occur between 30 and 32 weeks to
maximize placental antibody transfer.

• Influenza-related maternal mortality ranged from 25% to 70% among pregnant women; higher than that reported in
other countries.
• Pregnant women have been observed to be at a 18-fold higher risk of hospitalization as compared to healthy
nonpregnant women, and the risk is greatest among women in later stages of pregnancy

PERINATAL OUTCOMES
Maternal and Perinatal Outcomes of Influenza in Pregnancy after Treatment with Oseltamivir1
Prospective observational cohort study conducted in a tertiary hospital in Vellore; Patients with ILI – 73.2% (476/650)
Lab confirmed cases = 36.5% (174/476)
Significantly higher proportion of women
in Cohort 1 had severe illness requiring
inpatient and ICU care compared to
PCR-negative women (36.2% vs. 6.3%, P
< 0.001).
Abraham K, et al. J Glob Infect Dis. 2021 Jan 29;13(1):20-26
Influenza contributed to 36%
of the acute respiratory
infections in the observed
pregnant women.
↑ preterm births in the
infected women (RR – 2.75)
requiring prolonged NICU
care.
The expenditure toward treatment,
₹15,432 (~$ 216) for an average of 5
days, was three times higher for
women with severe illness
compared to women who had
outpatient-based care.
28. Benefits to the newborn2,3
Prevention is better than cure
• Robust immune response
• Prevention of influenza complications
• ↓ need for hospitalization
• ↓ adverse pregnancy and perinatal outcomes
• ↓ preterm and low birth weight babies
• Transplacental transfer of antibodies to
fetus
• Fills the gap till infant immunization can

can be administered at any time during pregnancy
FOGSI
2014 : Influenza vaccination is recommended for mothers from 26 weeks onwards
2016 : Influenza vaccine is recommended for women who would be pregnant in the influenza season especially in those who are at high risk of influenza related complications. All influenza vaccines available are recommended with the exception of the live intranasal vaccine. (Strength of recommendation: A; quality of evidence III)

Pregnant women are at increased risk for severe illness from influenza virus infection. Cardiopulmonary adaptive changes occurring during pregnancy, such as increased heart rate and stroke volume and reduced pulmonary residual capacity, may increase the risk of hypoxemia and contribute to the increased severity.
