Concept
Live Attenuated Vaccine
Live attenuated vaccines
use a
weakened form of the pathogen
that is still alive to stimulate a strong and long-lasting
immune response
without causing the disease. They are highly effective but require
careful handling and storage
to maintain their viability and are not suitable for individuals with
compromised immune systems
.

Poliovirus
Concept
Vaccine-derived Poliovirus
Concept
Herd Immunity
Herd immunity
occurs when a
significant portion of a population
becomes
immune to a disease
, reducing its spread and providing
indirect protection
to
those who are not immune
. Achieving
Herd immunity
can be through
natural infection
or vaccination, but the
threshold varies
depending on the
disease's contagiousness
.
Concept
Global Health Initiatives
Global Health Initiatives
are coordinated efforts by
international organizations
, governments, and non-profits to address
health challenges
that transcend national boundaries and require a
collaborative approach
. These initiatives aim to improve
health outcomes
, reduce disparities, and strengthen
health systems
worldwide, often focusing on
infectious diseases
,
maternal and child health
, and
non-communicable diseases
.
Concept
Immunization Coverage
Immunization coverage
refers to the
percentage of individuals
within a population who have received
specific vaccines
, serving as a
critical measure
for assessing the
effectiveness of vaccination programs
in
preventing infectious diseases
. High coverage rates are essential for achieving
herd immunity
, thereby protecting even those who are not vaccinated.
Concept
Public Health
Public health
is a discipline focused on protecting and improving the
health of populations
through
organized efforts
and
informed choices
of society, organizations, communities, and individuals. It encompasses a wide range of activities, from
disease prevention
and
health promotion
to policy-making and research, aimed at ensuring conditions in which people can be healthy.
Concept
Organic Electronics
Organic electronics
is a branch of electronics that deals with
conductive polymers
and
small organic molecules
, which offer flexibility, lightweight properties, and the potential for
low-cost production
. These materials enable the development of
innovative devices
like
organic light-emitting diodes
(OLEDs),
organic photovoltaics
(OPVs), and
organic field-effect transistors
(OFETs), revolutionizing applications in displays,
solar cells
, and sensors.
