Inoculation with a specific biological substance (antigen) to stimulate resistance or immunity to a particular disease.
Purpose of vaccination
To prevent or reduce problems that can occur from infection of a field strain of a disease organism
To incite high levels of immunity to protect birds in the face of aggressive endemic disease challenges.
To prevent heavy losses in the form of high mortality, morbidity and lowered protective performance by building up resistance in birds
To hyper immunize hens to maximize maternally derived antibody passed through the egg to the hatching progeny.
Proper vaccination is an essential part of a good poultry management program and for the success of any poultry operation. Effective preventive procedures such as immunisation protect hundreds of millions of poultry worldwide from many contagious and deadly diseases and have resulted in improved flock health and production efficiency.
Immunization cannot be a substitute for poor bio-security and sanitation. Thus, vaccination programs may not totally protect birds that are under stress or in unhygienic conditions. The primary objective of immunizing any poultry flock is to reduce the level of clinical disease and to promote optimal performance. Certain vaccines may also have an impact on human health (i.e. Salmonella vaccines).
For breeders – we also want to accomplish some additional goals:
A. Protect the bird (as a pullet and hen) against specific diseases.
B. Protect the progeny of the hen against vertical transmission of disease.
C. Provide passive immunity to progeny.
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious 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.

Here is another initiative to make study material available to everyone worldwide. Based on the new PCI guidelines and syllabus here we have a presentation dealing with the concept of Diphtheria vaccine.

A healthy immune system can defeat invading disease-causing germs (or pathogens), such as bacteria, viruses, parasites as well as cancer cells while protecting healthy tissue.
MenAfriVac (Meningococcal A Conjugate vaccine) is a lyophilized vaccine of purified meningococcal A polysaccharide covalently bound to tetanus toxoid (TT), which acts as a carrier protein. The vaccine consists of purified group-specific bacterial polysaccharide from Neisseria meningitidis group A.
The TT is prepared by extraction, ammonium sulfate purification, and formalin inactivation of the toxin from cultures of Clostridium tetani grown in a modified Mueller and Miller medium. The vaccine meets the requirements of WHO when tested by the methods outlined in WHO, TRS 962 (2011).
The MenAfriVac is provided as a 1/10 doses presentation consisting of a vial and an ampoule. Each vial contains a lyophilised powder of meningococcal group A polysaccharide conjugated to tetanus toxoid protein and excipients. Each ampoule contains the diluent with aluminium phosphate as adjuvant (the amount does not exceed 1.25 mg per single human dose) and thiomersal (0.01%) as preservative. The diluent is a white slightly opaque homogeneous suspension presented in a 0.5/5 ml ampoule.
The lyophilised conjugate is reconstituted just before use with the contents of one ampoule of diluent to obtain 1/10 doses of the final vaccine in a white homogeneous suspension. A single dose of vaccine is equivalent to 0.5 ml of the reconstituted suspension.
Each dose of 0.5 ml contains: Meningococcal A polysaccharide 10 mcg, TT (carrier protein) 10 to 33 mcg and excipients: mannitol, sucrose and Tris (hydroxymethyl) aminomethane.
Immunization, or immunisation, is the process by which an individual's immune system becomes fortified against an infectious agent (known as the immunogen).
Professional health hazards in a microbiology laboratory and Precautions to b...Abhishek Banerjee
Professional Hazards are common in a Microbiology Laboratory . So there should ways to reduce Hazards that may cause severe infections to not only the analyst but also to the community . This Presentation may just give a glimpse of the hazard and the possible way out .
The more injections that are given, the more people are exposed to needles and syringes. Also, if the number of injections given exceeds the supplies of sterile injection equipment, re-use of syringes and needles is likely to occur. Therefore, the greater the use of injections, the higher the risk to the patient and the community at large.

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!

Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

2. Vaccine
A vaccine is a type of medicine that trains the body's immune system so that
it can fight a disease it has not come into contact with before.
Vaccines are designed to prevent disease, rather than treat a disease once
you have caught it.
Sometimes, after getting a vaccine, the imitation infection can cause minor
symptoms, such as fever. Such minor symptoms are normal and should be
expected as the body builds immunity.
Therefore, it is possible that a person infected with a disease just before or
just after vaccination could develop symptoms and get a disease, because the
vaccine has not had enough time to provide protection.
Immunization cannot be a substitute for poor biosecurity and sanitation.
3. Types of Vaccines
There are five main types of vaccines.
Live, attenuated vaccines. These vaccines contain a version of the living
virus or bacteria that has been weakened so that it does not cause serious
disease in people with healthy immune systems.
Inactivated Vaccines: Killed germs
Toxoid vaccines: the toxins are weakened so they cannot cause illness.
Weakened toxins are called toxoids.
Subunit vaccines: Contains only a part of germ.
Conjugate vaccine is a type of vaccine which combines a weak antigen with
a strong antigen
4. Poultry Vaccine
There are two main types of vaccines available for poultry
Live attenuated vaccines
Inactivated vaccines
Production mainly in three forms:
Liquid , Freeze dried , Dust
5. GUIDELINES FOR SUCCESSFUL
VACCINATIONS
Always vaccinate only the healthy birds and keep them comfortable by
providing adequate heat, feed, water and good ventilation.
Get the vaccines from a reliable source and transport always in thermos flask
with ice cubes to maintain the cold chain.
Use Sterile needles and syringe for reconstitution.
Keep the reconstituted vaccine in the ice to maintain the cold chain.
Don't rush through the vaccination procedures. Use speed but maintain
accuracy.
6. Guidelines
Use reconstituted vaccines within 2 hours.
Burn and destroy the unused vaccine and empty vials.
For killed vaccines frequently shake
The bottle and care should be taken to avoid injecting in your own fingers.
Live vaccines should not be used in areas where the disease has not existed.
Vaccination should be done during the cold hours of the day.
7. STORAGE OF VACCINES
All vaccines should be protected from light.
All live vaccines must be stored between 2-8 C temperature and preferably in
deep freezer.
Killed vaccines should be stored below 8 C and should never be frozen.
Diluents may be stored in room temperature, but prior to every vaccination
the corresponding should be pre-chilled.
8. Handling
For all vaccines:
Storage temperature = 35-45º F (2-8º C).
Avoid freezing, extreme heating and intense light.
For Live Vaccines:
Transport to farm in cooler with ice packs to keep temperature constant.
Mix with diluent (reconstitute) just before application.
For Inactivated Vaccines:
Remove 24 hours prior to vaccinating so that the product can warm to room
temperature.
Also, can use warm water bath–do not exceed 100º F for more than 5 hours .
Do not leave bottles in direct sunlight during transport to farm.
Gently agitate bottles thoroughly prior to use.
9. Effect of temperature
Killed: Storage below 35F is damaging and change adjuvant.
Bound toxins release.
Don’t use freeze and expired vaccines.
12. Before Vaccination:
Remove the vaccine from the refrigerator and leave at room temperature for at least 12 hours in
order to reduce the viscosity of the chilled mineral oil, thus making the administration easier and
preventing intense local reactions.
Oil emulsion vaccines can also be warmed using a warm water bath prior to injection do not exceed
100° F (37° C) for more than 5 hours.
Gently agitate the vaccine container before and during the vaccination.
Vaccine Administration:
Administer the vaccine by using only the labeled dose at the chosen site of injection.
Needles should be regularly replaced, at least once every 500 birds.
Make sure that there is no air in the tube when the vaccine is administered.
Post Vaccination:
Record vaccine information and any problems that may occur regarding the birds or the vaccination
process.
After vaccination, all needles, syringes and plastic tubes must be washed prior to sterilization.
Sterilize all equipment which will be used in the vaccination, using autoclave, alcohol or boiling
water.
13. Crew Safety
Accidental human injection with oil emulsion products is a serious potential
danger when injecting this group of products. When this occurs, immediate
medical attention should be administered to the injured personnel.
When these products are injected into the hands or fingers, they can alter
circulation leading to severe injury. Immediate treatment will involve
removing the oil emulsified product to improve healing in the affected area.
This should be done by a qualified medical professional.
Proper injection technique and bird handling will reduce the potential for
human injection to occur. Bird handlers have an important responsibility to
present the birds for injection at the proper angle for the chosen site of
injection.
If the syringe operator has to struggle to reach the site of injection, the
chance for misapplication and accidental injection is much higher.
14. Errors
SC neck injection is a safe method of vaccination; however, improper technique
can cause harm to the birds. The following misapplications can have serious
consequences:
Vaccine is placed into the skin layer (intradermal). The area will develop into
a hard lump and/or scab that may rupture, which birds will peck at causing
bleeding and possible mortality. This will provide poor immunity.
Vaccine is injected into the neck muscle (intramuscular). The muscles of the
neck are very small and the immune reaction to the vaccine creates
inflammation and pressure. The damaged muscle heals by forming scar tissue.
This scar tissue can lead to birds with twisted necks, resulting in poor
performance.
15. Errors
If the needle is inserted too deeply, the needle will pass through the muscle
layer and vaccine can be injected into the spinal cord. Birds usually die within
a few minutes after injection into the spine.
Birds injected too close to the head will develop swollen heads which can
impair feed consumption and vision. Injecting too low results in swelling over
the back. Flock-mates may peck at these noticeable swellings causing more
problems.
16. Errors
When injection occurs through the side, off mid line, large vessels and soft
tissues may be damaged. The needle can damage blood vessels causing SC
bleeding. The thymus gland lies below the skin on both sides of the neck.
Vaccine injected into the thymus leads to swelling with an eventual necrosis
of the surrounding tissue.
Also, inserting the needle through the side can cause the needle to pass
through both layers of skin. Vaccine ends up wetting the feathers on the
opposite side of the neck and the bird does not develop immunity.
