Measles, Mumps and Rubella
Measles illness during pregnancy leads to increased rates of premature labor, spontaneous abortion, and low birth weight among affected infants and also birth defects11
Mumps developed in women during the first trimester of pregnancy, leads to an increased risk for fetal death11
Rubella developed in women during preganancy may lead to Congential Rubella syndrome11

Measles illness during pregnancy leads to
increased rates of premature labor,
spontaneous abortion, and low birth weight
among affected infants and also birth defects11
Mumps developed in women during the first
trimester of pregnancy, leads to an increased
risk for fetal death11
Rubella developed in women during
preganancy may lead to Congential Rubella
syndrome11

3. Congenital Rubella Syndrome
Congenital Rubella Syndrome is the
most serious feature of rubella4
It arises when pregnant women
become infected with the rubella virus
in the early stages of pregnancy4
Infection of the foetus occurs when the
rubella virus spreads from the placenta
and enters the foetal circulation4
4. CDC pink book (http://www.cdc.gov/vaccines/pubs/pinkbook/index.html)
4. Incidence of Congenital Rubella
Syndrome (CRS)
CRS is estimated to affect up to 85% of
infants born to women infected with rubella
during the first trimester of pregnancy4
Over 100,000 cases per year of CRS occur in
the developing world alone#
Congenital Rubella Syndrome is associated
with spontaneous abortion, premature
delivery and stillbirth4

syndrome who had hepatosplenomegaly,
thrombocytopenia, cataracts, deafness, Congenital
heart disease and mental retardation. Also Cutis
marmorata, a peculiar mottling common in infants and
young children with congenital rubella syndrome13

7. CRS Burden of disease1 : A systematic Review
1-15% of all infants suspected to have intra-uterine infection were
found to have laboratory evidence of CRS.
About 3-10% of suspected CRS cases are ultimately proven to have
confirmed CRS with the aid of laboratory tests.
CRS accounts for 10-15% of pediatric cataract. 10-50% of children
with congenital anomalies have laboratory evidence of CRS.
10-30% of adolescent females and 12-30% of women in the
reproductive age-group are susceptible to rubella infection in India.
RCVs are highly immunogenic in Indian adolescents and women.
The coverage data of RCVs in India is not available.
However, the coverage of MMR vaccine has been reported as 42%,
30% and 5% from Delhi, Chandigarh and Goa, respectively.
RCV = Rubella containing vaccines

8. Serological and molecular characterization of rubella
virus infection among children with Ocular defects of
Congenital Rubella Syndrome
A study conducted among infants in
south India observed that 25% of
congenital cataracts in children were
due to maternal rubella [Eckstein et al
1996], 50% infants were found to have
cardiovascular anomalies and 34.8% to
have developmental and neurological
defects

9. Rubella in Delhi: In-utero Infection and
Congenital Rubella Syndrome
A section of women (5-10%)
unexposed to natural or vaccinated
rubella virus remain susceptible and
add the burden of CRS in society by
contracting rubella infection during
pregnancy as can be seen from the
significant correlation between the in-
utero infection cases and CRS in new-
borns

10. Rubella Vaccine or combined
MMR vaccine?
CDC emphasizes on the use of
Combined MMR vaccine for
any indication11

benefit of protection against
measles and mumps11

11. MMR Vaccination
The MMR vaccine prevents measles, mumps
and rubella**
MMR Vaccine [PriorixTM - Measles, Mumps
and Rubella vaccine (live)] is highly
immunogenic after one dose, with reported
seroconversion rates of:
98.7% for measles14
95.5% for mumps14
99.5% for rubella14
