TYPES OF IMMUNITY1
CASE STUDY 1
MMR vaccine stands for the combination of vaccine given against measles, mumps
and Rubella. The vaccine contains attenuated or live weakened viruses including rubeola
virus causing measles, Rubula virus causing mumps and Rubella virus against which
immunity will be developed. Infants should receive this vaccine in two doses, first dose
between 9 to 15 months of age and the second between 15 to 6 years of age. Active immunity
is developed when the disease causing organism triggers body’s immune system to produce
antibodies against the organism thereby giving life time immunity to the person because if the
person encounters the disease in future his body will immediately produce antibodies as
immune response to combat the disease. Acquired immunization is a type of active immunity
that is elicitated by the administration of vaccine (Cdc.gov. 2020). Therefore MMR vaccine
provides active and acquired immunization to the child when he receives two doses of the
vaccine and develops life time immunity against the three viruses.
Measles, mumps and Rubella causes similar types of symptoms in children who have
received no prior immunization against these viruses. In the case study Julia is sceptical
about the concept of live and attenuated vaccine being given to the her baby because there are
cases where primary vaccination have failed and the child develops infection (Gagneur,
Pinquier and Quach 2015). Therefore it is necessary to give vaccination to infants at 12
months after their birth to reduce chances of infection. It is better to take a single vaccine
than three different vaccine for three different type of viruses (nhs.uk. 2020). It was stated
that MMR vaccine was more than 90% effective in eliminating measles (Doherty et al. 2016)
therefore it is advisable for the Julia and her baby to allow the baby receive MMR vaccine at
prescribed dose and duration.
