WHAT IS VACCINE ?

NEWER VACCINES and their
RELEVANCE
⚫‘New’ is relative:
❖New to the Immunization program
❖New because of recent discovery
❖New to the specific market or region (after Licensing)
⚫Introduction of a New vaccine may be
❖Vaccineagainsta disease notpreviously
covered by
immunization
❖New product formulationof a
vaccine (e.g.,a liquid vaccine replacing a
lyophilized vaccine)
❖New combination vaccine (e.g., DTP-HepB-Hib replacing
previous individual vaccines)
❖Vaccine that uses a new route of administration in place
ofa currently-usedvaccine (e.g.,an
replacing an oral vaccine)

NATIONAL IMMUNISATION SCHEDULE

⚫Contains 5 antigens (DPT + Hep.B + Hib)
⚫In UIP in India, Liquid vaccine available in 10 dose vials is being used
⚫Dose : 0.5 ml; 3 doses at 6, 10 and 14 weeks
⚫Targeted for children aged <1 year
⚫Booster dose is not recommended in India
⚫Common S/E : Redness, swellingand pain
at injection site,fever, irritability for short period
⚫AEFI is not higher than that reported with DPT vaccine alone
⚫Complete vaccine series induces protective efficacy of 95%
PENTAVALEN

Upon ingestion of OPV vaccine, the live attenuated polioviruses
replicate in the intestinal mucosa and lymphoid cells in
the oropharynx and intestine, in a similar manner to wild poliovirus
infection. Vaccine viruses are excreted in the stool
of the vaccinated person for up to 6 weeks after a dose, with
maximum shedding in the first 1 to 2 weeks after vaccination.
Revised fipv schedule in govt routine immunization started from
1 st janurary 2023.
Current doses:-2 doses of fipv vaccine each of 0.1 ml, intradermal
route at 6 and 14 weeks
Revised schedule:-3 does of fipv vaccine each 0.1 ml, ID at 6
weeks,14 weeks and 9 months

1. Killed whole bacteria with side
effects.
2. Capsular material (Vi antigen) that
is safer and more
effective.
3. Live oral vaccine, attenuated
s.thypi strain
Oral vaccines are still being
developed to distribute in
developing countries. Ty21a is also
being used to
carry foreign antigens from Shigella
and V.
cholerae.
•WHO recommends a 0.5 mL single
dose of CV in children from 6 months
and in adults up to 45 years
• In Endemic regions like India... WHO
also encourages routine programmatic
administration of CV to children at the
same time as other vaccines, at 9
months or in the second year of life.
Typhoid fever and paratyphoid fever
are most common in parts of the world
where water and food may be unsafe
and sanitation is poor. Travellers to
South Asia, especially Pakistan, India,
and Bangladesh, should take
precautionsto prevent infection.
The types of salomonella is organism
is salomonella thypoid and parathypoid
are more common in India
According mission
indradhanush thypoid
vaccine is included

MALARIA VACCINE
About half of the world's population is at risk. Large areas of
Africa and South Asia and parts of Central and South
America, the Caribbean, Southeast Asia, the Middle East,
and Oceania are considered areas where malaria
transmission occurs.

(DENGVAXIA)
⚫World’s first vaccine against Dengue
⚫By Sanofi Pasteur –first licensed in December, 2015, in Mexico
⚫Registered for use in individuals 9-45 years of age living in endemic
areas
⚫CYD-TDV –live recombinant tetravalent vaccine
⚫3-dose vaccine given on a 0/6/12 month schedule only who had

HIV vaccine
19
⚫Urgent global priority
Vaccine
⚫Realistic goal of HIV vaccine: to prevent viremia
Candidate Component
First generation Based on envelope proteins especially gp120
Second generationLive vectors (such as canarypox) or naked
DNA coding for different HIV genes
Third generation Regulatory non-structural proteins eg. Tat (a
transactivator of HIV gene expression) and
Nef (a multifunctional protein)
Majority of these vaccines are in phase I and phase II trials.
