What are the principles 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 safest type of vaccine?
Safety and stability Like inactivated vaccines, subunit vaccines do not contain live components and are considered as very safe. no risk of inducing the disease.
How many vaccines does a child get?
Currently, 16 vaccines – some requiring multiple doses at specific ages and times – are recommended from birth to 18 years old. Recommended vaccines include: Influenza (annual flu shot) Diphtheria, tetanus and pertussis (DTaP)
Who made the first vaccine?
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.
Does any virus have a vaccine?
Although most attenuated vaccines are viral, some are bacterial in nature. Examples include the viral diseases yellow fever, measles, mumps, and rubella, and the bacterial disease typhoid.
What virus do we have vaccines for?
We have children’s vaccines against measles, mumps, rubella, diphtheria, whooping cough, tetanus, chickenpox, polio, hepatitis A and B, rotavirus, pneumococcus, haemophilus influenzae and meningococcal disease. They have changed our expectations of mortality — and of parenthood.
What are the types of vaccines for babies?
During this time, your child receives the following vaccines:Diphtheria, tetanus and whooping cough (pertussis) (DTaP)Polio (IPV)Measles, mumps and rubella (MMR)Chickenpox (varicella)Influenza (flu) every year.
What are the 5 types of vaccines?
As mentioned earlier, there are five main types of vaccines: attenuated (live) vaccines, inactivated vaccines, toxoid vaccines, subunit vaccines, and conjugate vaccines.
How many virus vaccines are there?
There are about 20 safe and effective viral vaccines available for use throughout the world. This armamentarium represents one of the most cost-effective tools in public health and preventive medicine.
What type of vaccine is most effective?
Live attenuated vaccines contain whole bacteria or viruses which have been “weakened” so that they create a protective immune response but do not cause disease in healthy people. Live vaccines tend to create a strong and lasting immune response and are some of our best vaccines.
What are the 4 types of vaccines?
There are 4 main types of vaccines:Live-attenuated vaccines.Inactivated vaccines.Subunit, recombinant, polysaccharide, and conjugate vaccines.Toxoid vaccines.
What is a vaccine simple definition?
ANSWER. A vaccine is a substance that helps protect against certain diseases. Vaccines contain a dead or weakened version of a microbe. It helps your immune system recognize and destroy the living microbe during a future infection.
What is the concept of vaccination?
Vaccination is the administration of a vaccine to help the immune system develop protection from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism.
Are any vaccines live?
Currently available live attenuated viral vaccines are measles, mumps, rubella, vaccinia, varicella, zoster (which contains the same virus as varicella vaccine but in much higher amount), yellow fever, rotavirus, and influenza (intranasal).
What is vaccination and its types?
Four types of vaccines are currently available: Live virus vaccines use the weakened (attenuated) form of the virus. The measles, mumps, and rubella (MMR) vaccine and the varicella (chickenpox) vaccine are examples.
How are vaccines named?
The word vaccine, and vaccination, actually comes from the name for a pox virus—the cowpox virus, vaccinia, to be exact.
What type of vaccine is MMR?
MMR is an attenuated (weakened) live virus vaccine. This means that after injection, the viruses cause a harmless infection in the vaccinated person with very few, if any, symptoms before they are eliminated from the body.
What viruses have a vaccine?

How many successful vaccines are there?
The 20th century saw great successes at developing vaccines for many acute infectious diseases such that we now have an arsenal of 31 vaccines that are licensed in the United States to prevent infectious diseases [1,2].
