Introduction: Immunization is a process in which our immune system is strengthens by giving some antigenic preparation (vaccine) to our body. In other words it can also be define as the process to provide immunity to our body is known as immunization while vaccination is a term used for introduction of vaccine in body. Immunity is the term used for the ability to fight against diseases. Some people get confuse that vaccination and immunization both are the same word but they are different terms.
For kids it is very important to immunize them time to time to fight against diseases, as they always have weak immune system due to undevelop organ or undevelop immune system. Sometimes immunization also depends upon gender e.g some vaccines are given to girl child at the age of 11. Some adult are vaccinated in the age of 60s to prevent the diseases like Chicken-pox as it is more invasive in adult in comparison to child. In the case of some diseases one time immunization is sufficient while in some other cases 2-3 doses are recommended.
Immunization is of two types:
- Active immunization
- Passive immunization
Active immunization: It involves the immune system generates its own specialized defence cells and antibodies to fight off the infection and pathogen. This approach of immunization takes longer time because it needs to generate the right response, it also teaches the immune system to remember how to respond to the germ if it is reencountered in the future. In this type of immunity the work and response of memory cells increases because the memory cells are responsible for reencounter of pathogen. Most of the vaccines given to either to adult or kids are working on this principle. This type of immunity works for long time. Basically defense cell works in this manner in the case of vaccination, because vaccines are attenuated pathogen or killed pathogen and when they enter in the body they are recognize as foreign particles by immune syste and our immune system start working against them, since the pathogen is attenuated or killed so they can not harm the individual and easily our immune system works on that.
Working of active immunity: when our body firstly encounters with any foreign particle or pathogen or antigen(vaccine) it starts producing antibody against antigen or foreign particles. Along with this one special type (memory cell) of cell is produced which save the type of antigen in its memory, when the body encounter second time with the pathogen or foreign particle or antigen it starts producing antibody against them efficiently and then killed them.
Passive immunization: It involves direct introduction of antibiotics and antibody in the body, which works against infection, pathogen as well as other diseases. It does not work on the principle of memory cell.
Immunization works efficiently in the entire organism either it is human being or its animals.eg. dog. Human gets immunization to prevent the diseases while animals are vaccinated to reduce their pathogenic effect on human being.
Vaccination is a process of introduction of the vaccine in the body. Vaccine term was taken from the word Vacca which means cow in Latin and the first vaccine was prepared by Edward Jenner. It helps in the development of immunity, immunity which is developed by vaccination is known as adaptive immunity or acquired immunity .e.g Vaccination against polio, Smallpox, Hep. B, Pneumonia, Typhoid etc.
Vaccination can be done by one of the three methods by injection or by oral or by aerosol. The vaccine can be a drug because it fulfills all the criteria of the drug. Vaccines are more helpful and cost-effective public health measures that prevent many diseases, such as smallpox, chicken pox, rabbis and many more diseases.
Type of Vaccination
Vaccines are not occurring naturally they are prepared in the laboratory. When vaccines are introduced in our body they produce an antigenic response, and antibody starts work against the antigen, known as a primary immune response. Antibodies are protein molecule produced in our body against an antigen. There are many types of antibodies one of them is memory cell which is responsible for the secondary immune response of the immune system.
The secondary immune response is the response of our immune system when the same antigen attacks again then our antibody produces rapidly antibody and kill them. Antigens are foreign particles when enters in our body they produce an immune response, these antigens can be a living thing like protozoa, a virus, a bacteria or a non-living thing like dust particles or a pollen etc.
Click: Childhood Infection
Vaccines prevent many diseases, therefore, children are vaccinated for many diseases, children are vaccinated because they have a weak immune system at the time of birth or up to the age of 2 years. At the time of birth and up to six months, so vaccines are given to the baby e.g. HEp.B, Tetanus are given just after the birth of a child. After that in the interval of some time period, they are vaccinated. Some vaccinations are of one time while some are of 2, 3 and 4 times, which gradually increase the immunity of the child. Any person of any age can be vaccinated.
Vaccination is also known as immunization since it provides immunity against diseases.
The Immune System is the body’s defence mechanism – the army with which the body protects itself. The troops that make up this army are the white blood cells. Your immune system doesn’t work independently to the rest of your body and can respond positively to certain lifestyle choices and negatively to others.
Avoid succumbing to bugs this winter try these tips:
- Exercise –
Winter weather reduces our movement. Exercise supports our detox organs and keeps our lymph moving.
- Get Outside –
Reduced fresh air and sunshine in the winter impair the immune system.
- Sleep –
The greatest tool for stress reduction and immune support is sleep. Commit to at least eight hours a night.
- Alcohol –
Be mindful of alcohol consumption. Too much depresses the immune system and makes it easier to get sick.
- Hand Washing –
So simple we forget. Wash your hands with hot water especially after computer use before making food.
- Vitamin D3 –
Take 3,000 – 4,000 IU of Vitamin D3 to help reduce winter flu and seasonal moodiness.
- Probiotics –
Good bacteria detox what we eat and modulate immune system.
- Enzymes –
Take enzymes with heavy holiday meals to improve digestion.
- Multi –
Be consistent about taking a daily multivitamin with high levels of B-Vitamins, C and Zinc.
- Immune Boosting Drinks –
Have lots of bone broth, turmeric + ginger tea, and green juice + ginger this winter.
- Fruits + Veggies –
Bump up your intake of plant foods and green powders. Plant phytonutrients help reduce stress and inflammation.
- Reduce Triggers Foods –
Gluten, Dairy, Sugar, and Alcohol are the most common trigger foods. Be intentional about when you eat them or substitute for clean whole foods.
