infections in humans
Source: WHO

of 6–12 weeks in infants.
• The maximum age for the last dose was 32 wee ks.
• 6 weeks and 14 weeks in Latin America or 6 weeks and
15 weeks in Europe.

Hib Vaccines

Polysaccharide Vaccine

The first Hib vaccine licensed was a pure polysaccharide vaccine,
first marketed in the US in 1985

Conjugate Vaccine: The shortcomings of the polysaccharide vaccine
led to the production of the Hib polysaccharide-protein conjugate
vaccine. Attaching Hib polysaccharide to a protein carrier greatly
increased the ability of the immune system of young children to
recognize the polysaccharide and develop immunity.

Hib conjugate vaccines have been effective against all manifestations
of Hib disease, with a clinical efficacy between 95-100%.

Multiple combinations of Hib and other vaccines have
been licensed in the United States, reducing the number
of shots necessary to vaccinate a child. Hib vaccine
combined with diphtheria-tetanus-pertussis-polio
vaccines and Hepatitis B vaccines are available in the US.
The World Health Organization (WHO) has certified
several Hib vaccine combinations, including a
pentavalent DTP+HBsAg+Hib combos for use in
developing countries.

Vaccine under development at Bharat Biotech Limited.

Serum Institute of India

◦ Issues with Shan5: Facing Vaccine Quality issues regarding
physical appearance reported to WHO by Colombia, Comoros,
and Nepal ⇨ No AEFI reported so far ⇨ However, Shan5 likely
to be removed from the list of WHO prequalified vaccines if
corrective measures are not instituted within 2 months.
 Panacea
Biotec
◦ Easy five - Pentavalent Combo of DTP+HBsAg+Hib
◦ Issues with Easyfive: During site audit (27 June-1 July
2011) at Lalru, Panacea failed to meet the quality
requirements for WHO prequalification ⇨ As per the
recommendations of the ad hoc Committee, Easyfive has
be delisted from the WHO prequalified list of vaccines.

WHO/TDR Project:
Mapping of Products R&D
Landscape in Drugs, Diagnostics
and Vaccines in India
Brief Outline of the Project
Mapping of the product R&D landscape for infectious diseases of
public health importance in India through literature surveys, and
internet/database searches.
The Mapping included the following:
a. Cover R&D activities in the area of drugs, diagnostics and
vaccines for infectious tropical diseases.
b. Identify gaps and opportunities for product innovation in India.
c. Create a database of institutions (public and private) with relevant
R&D capacity for discovery and development and manufacturing.
d. Create a database of available resources including technologies,
pathogen strains, screening assays as well as potential regional
funding sources that could support such regional efforts.


India is an endemic country for several Infectious diseases.

Diagnostics is still unavailable for some of the diseases.

Evaluation is a problem.

Lack of networking among investigators.

Lack of platform technology development, a change visible
in recent times.

Kits and chips also were not in sight earlier, which are
coming up now.

Insufficient Industry-Academia partnership.

Hurdles in IP procedure.


As identified from the inputs collected from the Principal Investigators:
Finance.
Infrastructure.
Reagents.
More basic research for neglected tropical diseases.
Inability to differentiate between active and latent
disease or active disease vs. contacts.
Not enough clinical samples.
Lack of containment facilities.
Lack of human resources.
Quality assurance.
Limited option for test validation.
Inaccessibility to good quality validated panels of sera.
Imported kits, chips, reagents make diagnostics costly.
MAPPING OF DRUGS

Gaps and roadblocks, as perceived by
respondents from Academia :
◦ Lack of manpower.
◦ Lack of funding.
◦ Lack of infrastructure.
◦ Neglect of some diseases over others.
Vaccine manufacturers from India started the journey by
manufacturing EPI vaccine, a niche created by exit of few
multinationals from the area.
But they have gone a long way after that …
WHO prequalification regulations getting more stringent.
Older public sector units have been converted to testing centers.
New manufacturers have entered the scene.
Few have done very well .

Tropical Diseases in India
Another WHO-SEARO Sponsored Project was done
on
Mapping of National Centres / Institutions on Tropical
Diseases in India
A thorough mapping of:
All relevant National medical, technological, research
organizations, universities centres/institutions
The selection criteria were their strengths by way of
contribution in the area of Tropical Diseases research,
teaching, as well as training.
The major aims and objectives:
To assess the profile, strengths and comparative
advantages of the institutes and establish how each
of them could contribute towards control and
elimination of Tropical Diseases from the region.
The major areas where information was collected were:
(i) profile of institution / university,
(ii) strengths,
(iii) Funding obtained from National , International agencies, and
NGOs
(iv) outputs.
