VACCINE INDUSTRY
PRESENT AND FUTURE
INTRODUCTION
• Every year 3 million deaths are prevented and
750,000 children are saved from disability by
vaccines(WHO)
• Why do we need vaccine?
⬧ Common communicable diseases
⬧ Geographic variation in disease spread
⬧ Every 1 USD invested in childhood vaccine
save 18 USD
⬧ Increased life expectancy to economic
growth
Vaccines
• WHO:
 A vaccine is any preparation intended to
produce immunity to a disease by
stimulating the production of antibodies
 Vaccines include, for example, suspensions
of killed or attenuated microorganisms, or
products or derivatives of microorganisms
Pharmaceuticals
 Focus on prevention – not
patients, but healthy subjects
 Focus on treatment – patient
is generally sick
 Key role for the government
agencies
 Key role for healthcare
players
 Very low acceptance of side
effects
 Acceptance of side effects
varies by severity of disease
Manufacturing
 High manufacturing and
supply chain complexity
(Cold Chain Management,
complex biological
processes)
 Medium manufacturing and
supply chain complexity
(Easier to handle chemical
synthesis in most cases)
 Small
 Massive sales force
commitment
Regulatory
Vaccines
Marketing/ Sales
Vaccines vs Pharmaceuticals
 Major sales through
government
 Very few generic products
(Due to manufacturing
complexity)
 Sales through physician as
prescriber
 Increasing generic threat
A typical cold chain
• The system used for keeping and distributing
vaccines in good condition
• This consists of a series of storage and
transport links, all of which are designed to
keep the vaccine at the correct temperature
until it reaches the user
A typical cold chain
Supply chain
• It’s not just about developing safe and
effective vaccines, it’s about getting vaccines
to the right place, at the right time, in the right
condition
Problems in supply chain
• Tight price competition
• Damage to vaccines during transportation Storage problems
• Due to less financial incentive from govt. to
manufacturers – insufficient doses
• Demand uncertainty
• Manufacturing interruptions - required to
maintain cGMP standards so high product
rejection rate – supply can be impacted
Stages of vaccine development
• A vaccine must be licensed first by the
appropriate authority for the use in the country
or WHO
• For licensing of a new vaccine, the vaccine
manufacturer should conduct the phase I, II
and III trials and must submit their results to
authority approval
• Good clinical practice (GCP) and ethical
guidelines are needed for approval
Stages of vaccine development
Stages of vaccine development
• Disease target is identified
• Antigen is identified
• Vaccine candidate is designed
• Vaccine is characterised
 Feasibility
 Formulation
 Identity
 Purity
 Stability
Stages of vaccine development
 Preclinical studies begin, testing for the
following:
 Potency
 Toxicology
Stages of vaccine development
 Manufacturing begins on a pilot scale, the
candidate is evaluated according to the
following controls:
 Good Clinical Practices
 Clinical Good Manufacturing Practices
(cGMP)
 Sterility
 Quality control
Stages of vaccine development
 Investigational New Drug (IND) application is
filed
 Phase I clinical testing begins
 Phase II clinical testing begins
 Phase III clinical testing begins
 Biologics License Application (BLA)
application is filed
 The authorities approve the candidate
 Phase IV clinical testing begins
Trial phases
• Clinical trials are governed by strict regulation
• The proceedings are monitored by
government authorities as well as
manufacturers’ own Global Safety Board
(GSB)
• At least three phases to clinical trials,
• A fourth phase might be necessary if
 The medicine can be improved
 To provide answers to questions from the
regulatory authorities
Phase 1
• The first time a new treatment or vaccine is
tested in humans
• Usually be given to a small group of healthy
volunteers
• In some cases – such as when a new
medicine is being tested as a treatment for a
terminal illness like cancer - it may be tested
on volunteers who have the condition
Phase 1
• The principle objectives in Phase I are to
 Make sure that the new vaccine presents no
major safety issues
 Clarify that it can reach the targeted body
area, and remain there long enough to
deliver its benefits
 Gain preliminary evidence that it could offer
therapeutic value, or prevent the disease or
condition
Phase 2
• A trial involving a larger group of people
• Usually (but not always) include patients who
have the condition the potential medicine is
targeting, and aim to establish
 Effectiveness in treating the condition
 Effectiveness in preventing the condition (if
the volunteer does not already have it)
 Appropriate dosing levels
Phase 2
• The performance of the medicine may be
compared against a group of patients
receiving a placebo
• A placebo: a treatment that looks the same as
the potential new medicine, but has no active
ingredients
• Neither the patients nor the researchers have
any idea which volunteers receive which
treatment (double-blinded placebo control)
Phase 3
• A much larger trial, often involving hundreds,
possibly thousands of participants coming
from a range of different countries
• The principle objectives in Phase III are to
 Demonstrate the safety and effectiveness of
the new medicine or vaccine in the typical
patient likely to use it
 Confirm effective dosing levels
Phase 3
• The principle objectives in Phase III are to
 Identify side effects or reasons why the
treatment should not be given to people with
the condition in question (known as
“contraindications”)
 Build knowledge of the benefits of the
medicine or vaccine and compare them with
any risks
 Compare results against any currently
achieved by existing treatments
Phase 3
• A new vaccine usually needs to offer the
prospect of better treatment for patients than
any treatments that are already available.
• Phase III trials may last several years
• If a new medicine or vaccine completes Phase
III with positive results → seek regulatory
approval to make it available in a range of
countries or regions
Phase 3
• In the case of a new medicine, regulators will
determine how it should be used, and which
patients should qualify for it, based on all the
evidence from clinical and pre-clinical studies
➔ A medicine/vaccine’s indication
Phase 4
• Done after a drug has been shown to work
and has been granted a license
• The main reasons for running phase 4 trials
are to find out
 More about the side effects and safety of the
drug
 What the long term risks and benefits are
 How well the drug works when it’s used
more widely
GLOBAL VACCINE INDUSTRY

• Cost effectiveness of immunizations
• New funding opportunities (Gov, PPP,
donors, Foundations,..)
• New research techniques and
manufacturing technologies
Growth factor
Combination of :
• Increasing demand, new target
population, larger emerging markets
• Higher prices, improved profitability for the
industry (blockbuster vaccines..)
Managing the product life cycle
• On launch
⬧ Typically, only one producer, who owns
product and process intellectual property
⬧ Limited capacity, low demand, high
production costs and high prices
Managing the product life cycle
• Market penetration
⬧ New manufacturers will enter the market,
either through their own development efforts
or through licensing of the original
manufacturer’s patent
⬧ Capacity increase
⬧ Limited price tiering will be possible
Managing the product life cycle
• The product reaches maturity and the
intellectual property protection expires
⬧ Many manufacturers, both in the developing
as well as the industrialised world
⬧ Production costs are low and often there will
be overcapacity so that availability is high
and demand is global
⬧ Prices will be heavily tiered

Challenges for the vaccine market
• Failing realisation for mass vaccination
(Hepatitis B)
• Funding
• High maintenance
• Slow regulatory approval
• Dependence on government
SWOT ANALYSIS
• Strengths
• Weaknesses
• Opportunities
• Threats
SWOT ANALYSIS
• Only two to three vaccine manufacturers
compete for each disease (except influenza)
• This lack of competition combined with public
health requirements to guarantee a stable
supply of vaccines has resulted in a recent
upward shift of vaccine prices for specialty
vaccines
Strengths
• Prevent disease
• Vaccines are widely available, and programs
have reduced cost as a barrier to vaccination
• Vaccines will not face significant generic
competition
Weaknesses
• Vaccine research and development is lengthy
and expensive
• Less awareness
• Vaccine manufacturing : High cost
• High maintenance products
• Regulatory approvals
• Funding to new enterprises
Opportunities
• Vaccines for diseases currently without a
vaccine
• Improved vaccines for partially vaccine –
preventable diseases
• Global recognition of the benefits of
immunisation
• Combination vaccines (therapeutic vaccines,
vaccines effective against more strains,
universal influenza vaccine…) – way ahead
Threats
• Only strong players so intense competition
• Domestic companies depend on government
procurement to push volumes
• Gestation period is long
• Ageing of their product basket
• Vaccine distribution networks
• The anti-vaccine movement
FUTURE PERSPECTIVE
• The main future opportunities: the
pneumococcal, meningococcal and HPV
vaccine sectors → there is a large medical
need for better products
• For pneumococcal and HPV vaccines:
candidates offering a higher subtype coverage
than existing products can be expected to
yield excellent returns

field of biotechnological research and
manufacturing technologies which will play a
dominating role further developments of this
industry
FUTURE DEVELOPMENTS
Adjuvants
Conjugate vaccines
• Substances that helps
vaccine to produce a
stronger immune response
• Faster response
• Broad immunity
• Conjugation of sugar
molecules present on
bacteria to a strong
immunogenic carrier protein
• Can stimulate cell mediated
long lasting memory
To increase and prolong the immune response to the
vaccine antigen
To increase vaccine efficacy in the elderly population
Nucleic acid vaccines
• Injection of DNA encoding the antigen
• Involves transfection of DNA plasmid
containing antigen coded gene into target cells
which results in immune response
• Ease of manipulation
• Simple manufacturing
• More stable
• Targeting a specific organ
CONCLUSION
• Vaccine industry has been proved to be one of
the fastest growing sectors of the past decade
and is forecasted to do so in future also
• Driven by novel, high-price vaccines, the
7MM’s paediatric and adolescent vaccines
market will almost quadruple in size by 2016
CONCLUSION
• Due to ageing populations, the emergence of
new technologies and the increasing
awareness for vaccine-preventable diseases,
adults and the elderly are coming into focus as
an attractive target population for future
vaccine development
• Advancement in the molecular biology and
vaccine delivery systems will be the key for
further development of this industry
