Why do vaccines matter?
By preventing episodes of vaccine-preventable diseases, vaccination can also help avert associated out-of-pocket medical expenses, healthcare provider costs, and losses in wages of patients and caregivers.

What is the basic principle of vaccination?
Vaccination is one of the most effective medical interventions to reduce morbidity and mortality of infectious diseases. The main principle of vaccination is the proactive induction of a protective immune response by mimicking the natural interaction of an infectious pathogen (bacteria, viruses, etc.)
What is the concept of vaccination?
Vaccination: The act of introducing a vaccine into the body to produce immunity to a specific disease. Immunization: A process by which a person becomes protected against a disease through vaccination. This term is often used interchangeably with vaccination or inoculation.
What happens when a vaccine is injected into the body?
Your immune system reacts to the vaccine in a similar way that it would if it were being invaded by the disease — by making antibodies. The antibodies destroy the vaccine germs just as they would the disease germs — like a training exercise. Then they stay in your body, giving you immunity.
What happens during vaccination?
A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.
What are the 3 types of injections?
The three main routes are intradermal (ID) injection, subcutaneous (SC) injection and intramuscular (IM) injection. Each type targets a different skin layer: Subcutaneous injections are administered in the fat layer, underneath the skin. Intramuscular injections are delivered into the muscle.
How are vaccines done?
Several vaccines are made by taking toxins and inactivating them with a chemical (the toxin, once inactivated, is called a toxoid). By inactivating the toxin, it no longer causes disease. The diphtheria, tetanus and pertussis vaccines are made this way.
How many vaccines do babies get?
How many vaccines do children get if the schedule is followed? Currently, 16 vaccines – some requiring multiple doses at specific ages and times – are recommended from birth to 18 years old.
What was the first vaccine for?
The smallpox vaccine was the first vaccine to be developed against a contagious disease. In 1796, the British doctor Edward Jenner demonstrated that an infection with the relatively mild cowpox virus conferred immunity against the deadly smallpox virus.
What is the history of vaccination?
The practice of immunisation dates back hundreds of years. Buddhist monks drank snake venom to confer immunity to snake bite and variolation (smearing of a skin tear with cowpox to confer immunity to smallpox) was practiced in 17th century China.
Who discovered the Ebola vaccine?
It was developed by NIAID in collaboration with Okairos, now a division of GlaxoSmithKline. For the trial designated VRC 20, 20 volunteers were recruited by the NIAID in Bethesda, Maryland, while three dose-specific groups of 20 volunteers each were recruited for trial EBL01 by University of Oxford, UK.
What kills Ebola?
Ebola virus also can be killed by many common chemical agents. Chemical agents that will kill the virus include bleach, detergents, solvents, alcohols, ammonia, aldehydes, halogens, peracetic acid, peroxides, phenolics, and quaternary ammonium compounds.
How did Ebola start?
Ebola virus was first discovered in 1976 near the Ebola River in what is now the Democratic Republic of Congo. Since then, the virus has been infecting people from time to time, leading to outbreaks in several African countries. Scientists do not know where Ebola virus comes from.
What is Ebola full name?
Zaire ebolavirus, more commonly known as Ebola virus (/iˈboʊlə, ɪ-/; EBOV), is one of six known species within the genus Ebolavirus. Four of the six known ebolaviruses, including EBOV, cause a severe and often fatal hemorrhagic fever in humans and other mammals, known as Ebola virus disease (EVD).
Is Ebola extinct?
Unfortunately, some viruses are unlikely to ever go extinct, because we aren’t their only host. In humans, outbreaks of Ebola end all the time. There have been at least 26 across Africa since the virus was discovered in 1976, and these are just the ones that caused enough cases to be picked up by health authorities.
What class of virus is Ebola?
Ebola virus is a class A bioterrorism agent, known to cause highly lethal hemorrhagic fever. The mortality rate can be as high as 90 percent. Because the Ebola virus is so hazardous, it is classified as a biosafety level 4 agent – the level assigned to the most dangerous agents known.
Who is most at risk for Ebola?
For most people visiting countries in sub-Saharan Africa, the risk of exposure to the Ebola virus is minimal. People most at risk are those who care for infected people, such as aid workers, or those who handle their blood or body fluid, such as hospital workers, laboratory workers and family members.
What is the importance of immunization?
Immunisation saves lives. It protects you, your family and your community. Immunisation helps protect future generations by eradicating diseases. Many infectious diseases are rare or eradicated now as a result of immunisation programs, but new infectious diseases are appearing around the world.
What is the importance of immunization to prevent diseases?
Vaccinations prevent you or your child from getting diseases for which there are often no medical treatments. These illnesses can result in serious complications and even death. A small number of people may be susceptible to diseases, such as those with impaired immune systems.
What is the process of immunization?
Immunisation describes the process whereby people are protected against illness caused by infection with micro-organisms (formally called pathogens). The term vaccine refers to the material used for immunisation, while vaccination refers to the act of giving a vaccine to a person.
What is full immunization?
Full immunization: Defined as immunization of a child with one dose of Bacille Calmette Guerin (BCG), 3 doses of Diphtheria Pertussis and Tetanus (DPT), Oral Polio Vaccine (OPV), Hepatitis B Vaccine and one dose of Measles vaccine within the age of one year.
What do u mean by immunization?
Immunization is the process of giving a vaccine to a person to protect them against disease. Immunity (protection) by immunization is similar to the immunity a person would get from disease, but instead of getting the disease you get a vaccine. This is what makes vaccines such powerful medicine.
What is difference between vaccination and immunization?
How did vaccination protect you?
Vaccines help your immune system fight infections faster and more effectively. When you get a vaccine, it sparks your immune response, helping your body fight off and remember the germ so it can attack it if the germ ever invades again.
What type of diseases can be prevented through vaccination?
Vaccine preventable diseases currently include:
- diphtheria.
- tetanus.
- pertussis (whooping cough)
- poliomyelitis (polio)
- measles.
- mumps.
- rubella.
- haemophilus influenzae type b infections.
What was first vaccine?
The smallpox vaccine, introduced by Edward Jenner in 1796, was the first successful vaccine to be developed. He observed that milkmaids who previously had caught cowpox did not catch smallpox and showed that inoculated vaccinia protected against inoculated variola virus.
Who developed vaccination?
Edward Jenner, Cowpox, And Smallpox Vaccination. We begin our history of vaccines and immunization with the story of Edward Jenner, a country doctor living in Berkeley (Gloucestershire), England, who in 1796 performed the world’s first vaccination.
Who gave the idea of vaccination for the first time?
In May 1796, Edward Jenner found a young dairymaid, Sarah Nelms, who had fresh cowpox lesions on her hands and arms (Figure 3). On May 14, 1796, using matter from Nelms’ lesions, he inoculated an 8-year-old boy, James Phipps.
How was first vaccine developed?
First vaccines The method Jenner tested involved taking material from a blister of someone infected with cowpox and inoculating it into another person’s skin; this was called arm-to-arm inoculation.
What are the first set of vaccines for babies?
At 1 to 2 months, your baby should receive vaccines to protect them from the following diseases:
- Hepatitis B (HepB) (2nd dose)
