A vaccine is a biological preparation of weakened or killed pathogen such as bacterium or virus that will improves immunity to a particular diseases.
The principle of immunization or vaccination is based on the property of ‘memory’ of the immune system.
The process of introduction of vaccine into an individual to provide protection against a disease called vaccination.
Immunity is the ability of the body to protect against all types of foreign bodies like bacteria, virus, toxic substances etc. As it protects us from diseases it is also called disease resistance. Immunity is done by immune system which is a complex network of lymphoid organs such as bone marrow, thymus, spleen etc. It is mainly of two types- Natural and Acquired immunity.
Humoral immunity is defined as the immunity mediated by antibodies, which are secreted by B lymphocytes.
B lymphocytes secrete the antibodies into the blood and lymph
The word "vaccine" originates from the Latin word “vacca”, meaning “cow” a virus (cowpox) which manly effect the cow. which Edward Jenner demonstrated in 1798 could prevent smallpox in humans.
A Vaccine is a substance that is introduced into the body to stimulate the body’s immune response. (Production of an Antibodies)
Vaccine is an immune biological substance designed to produced specific protection against a disease causing pathogen
It is given to prevent an infectious disease from developing disease in the person.
Vaccines contain the same germs that cause disease. (For example, measles vaccine contains measles virus, and Hib vaccine contains Hib bacteria)
But they have been either killed or weakened to the point that they don’t caused disease.
This topic covers the brief introduction of Ag and Ab in detail. Types and functions of Ig is explained in detail. Paraproteinemias is explained with simple pictures.

Toxoids
vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future.
HISTORY OF VACCINES-
EDWARD JENNER conduct experiments in 1796 that lead to the creation of the first smallpox vaccine for prevention of smallpox.
A vaccine for RABIES is developed by LOUIS PASTEUR .
Vaccine for COLERA and TYPHOID were developed in 1896 and PLAGE vaccine in 1887.
The first DIPHTHERIA vaccine is developed in about 1913 by EMIL ADOLPH BEHRING,WILLIAM HALLOCK PARK.
The whole cell PERTUSIS vaccines are developed in 1914.
A TETANUS vaccine is developed in 1927.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Anti ulcer drugs and their Advance pharmacology ||
Anti-ulcer drugs are medications used to prevent and treat ulcers in the stomach and upper part of the small intestine (duodenal ulcers). These ulcers are often caused by an imbalance between stomach acid and the mucosal lining, which protects the stomach lining.
||Scope: Overview of various classes of anti-ulcer drugs, their mechanisms of action, indications, side effects, and clinical considerations.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Types of vaccines
1. 1
Prepared by: Anish Dhakal (Aryan)
anishdhakal718@gmail.com
MBBS Student
Patan Academy of Health Sciences
2. OBJECTIVES
To define vaccine
To discuss the types of
vaccines
To discuss the Expanded
Program on Immunization
(EPI) schedule of Nepal
with OPV and IPV rationale
2
3. WHAT IS VACCINE?
Vaccine is an immuno biological substance
designed to produce specific protection against
a give disease
Artificial Active Immunity
Triggers humoral and cell mediated immune
response or both mimicking the natural infection
3
4. TYPES OF VACCINES
Live attenuated vaccines
Inactivated /Killed vaccines
Toxoid vaccines
Cellular fraction / sub unit
Conjugate vaccines
Acellular vaccines
DNA vaccines
Recombinant vaccines
Combination vaccines
4
5. LIVE ATTENUATED VACCINE
Prepared from live (generally attenuated) organism
Organisms lost pathogenicity but retain immunogenicity
due to repeated culturing
More potent than other vaccines because:
Resultant antigenic dose is higher and sustained
Contain all major and minor antigenic components
Engage body tissues causing persistent immune response
Viral live vaccines are provoke excellent immune response
Immunization usually with a single dose
5
6. LIVE ATTENUATED VACCINE
Example of live vaccines
include Measles, Mumps,
BCG, Influenza, Rubella and
oral polio vaccine
Contraindication
Immunocompromised state
(due to therapy or disease)
Pregnancy
6
7. INACTIVATED OR KILLED VACCINE
Organism are killed by heat or
chemical and injected into body
Usually safe, requires adjuvants
and less efficacious than live
vaccine
Requires booster dose
Examples include J.E , Rabies,
Hepatitis B, IPV
Contraindication
Severe local or general reaction
in previous dose 7
8. TOXOID VACCINES
Toxins produce by organism
are detoxicated and used in
preparation of vaccine
Antibodies produced
neutralized the toxin rather
than act upon the organism
Toxicity is lost but antigenicity
is retained
Examples – Diphtheria and
Tetanus
8
9. CELLULAR FRACTION / SUB UNIT
Conjugate vaccines
Pieces from coats of bacteria are
linked to carrier protein which cause
immune response
Example – Hib
Acellular vaccines
Vaccine that contain cellular material but
not complete cell
Only those antigen/epitopes that evoke
best immune response are selected
Example - Pertussis
9
10. DNA VACCINES
Genes for microbe’s antigen are introduced into
body, some cells take up the DNA
Microbe’s DNA then instructs cell to synthesize
antigens
The person’s own body become vaccine making
factories creating antigens required to provoke
immune response
DNA vaccines being tested in humans include
those against the viruses that cause influenza and
herpes
10
12. RECOMBINANT VECTOR VACCINES
Similar to DNA vaccines
except use of a vector
Use of attenuated and live
virus or bacterium to introduce
microbial DNA to the body
Example – Hep. B , Cholera
12
13. COMBINATION VACCINES
More than one kind of
immunizing agent is
included in the vaccine
It simplifies
administration and
reduces cost
Example - DPT, DT,
MMR
13
16. Routine immunization with OPV must cease after the
eradication of poliovirus because of the danger of
outbreaks of circulating vaccine-derived poliovirus and
the risk of VAPP (Vaccine Associated Paralytic
Poliomyelitis)
In the regions of the world in which wild-type poliovirus has
been eliminated, moving to an IPV or IPV/OPV sequential
schedule will reduce or eliminate the risk of VAPP and
outbreaks of circulating vaccine-derived poliovirus, as well as
increase the likelihood of countries agreeing to stop
administering OPV after eradication is achieved.
IPV could also be used with OPV in routine schedules to
increase immune responses and to decrease the circulation of
wild-type poliovirus in countries in which transmission has not
been stopped.
17. IPV – RATIONALE
Type 2 poliovirus mutates into virulent form
IPV contains killed virus, so IPV mitigates this risk
IPV in addition to OPV provides better immunity
All countries switched from tOPV to bOPV (minus type 2) 2016
Introduction of IPV before this ensure protection against type 2
Once virus circulation stopped everywhere, OPV withdrawn
