what is vaccination?

Question

Answer

Vaccination is a method to prevent spread of infectious diseases in the community. It is carried out by injecting or inoculating vaccine the killed or chemically weakened pathogens or their surface coatings into body of a healthy person...

Answer

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.

To understand how vaccines work, it helps to look first at how the immune system works, because vaccines harness the natural activity of your immune system. This short animation explains how vaccines enable the body to make the right sort of antibodies to fight a particular disease.

Answer

Vaccination is the administration of a vaccine to help the immune system develop protection from a disease. Vaccines contain a microorganism in a weakened or killed state, or proteins or toxins from the organism. In stimulating the body's adaptive immunity, it helps prevent sickness from an infectious disease.

Answer

The process of giving vaccine orally or injection to the body  against diseases is called vaccination.......:)

Answer

**Vaccination: An Overview**

Vaccination, also referred to as immunization, is a medical procedure that involves the administration of vaccines to stimulate the body's immune system to recognize and fight against specific infectious diseases. It is a highly effective preventive measure that helps protect individuals from various diseases and can contribute to the eradication or control of certain diseases on a global scale.

**How Vaccines Work**

Vaccines contain weakened or killed forms of harmful microorganisms, such as bacteria or viruses, or parts of these microorganisms. When administered, vaccines mimic an infection, prompting the immune system to mount a response. The immune system recognizes the foreign substances in the vaccine as potential threats and produces an immune response, including the production of antibodies and the activation of immune cells.

**Types of Vaccines**

There are several types of vaccines, including:

1. **Live Attenuated Vaccines**: These vaccines contain weakened forms of the live microorganism, which can replicate in the body but usually do not cause disease. Examples include the measles, mumps, and rubella (MMR) vaccine.

2. **Inactivated Vaccines**: These vaccines contain killed or inactivated forms of the microorganism, which cannot cause disease but can still stimulate an immune response. Examples include the polio vaccine and the hepatitis A vaccine.

3. **Subunit, Recombinant, or Conjugate Vaccines**: These vaccines contain only specific pieces of the microorganism, such as proteins or polysaccharides, to stimulate an immune response. Examples include the human papillomavirus (HPV) vaccine and the Haemophilus influenzae type b (Hib) vaccine.

4. **Toxoid Vaccines**: These vaccines contain inactivated toxins produced by certain bacteria. They stimulate the immune system to produce antibodies against the toxins, which effectively protects against diseases caused by these toxins. Examples include the tetanus and diphtheria vaccines.

**Benefits of Vaccination**

Vaccination provides numerous benefits, including:

1. **Disease Prevention**: Vaccines are highly effective in preventing various infectious diseases, such as measles, polio, hepatitis, and influenza.

2. **Individual Protection**: Vaccinated individuals are less likely to contract and suffer from vaccine-preventable diseases, reducing the risk of severe complications, hospitalization, and death.

3. **Herd Immunity**: When a significant portion of the population is vaccinated, it creates herd immunity, protecting vulnerable individuals who cannot be vaccinated due to medical reasons or age.

4. **Disease Eradication**: Vaccination has led to the eradication of diseases such as smallpox and has significantly reduced the global burden of diseases like polio.

**Conclusion**

Vaccination plays a crucial role in public health by preventing the spread of infectious diseases and protecting individuals from potentially severe complications. By stimulating the immune system to recognize and fight specific pathogens, vaccines have proven to be one of the most effective tools in disease prevention. It is essential to follow vaccination schedules recommended by healthcare authorities to ensure optimal protection for both individuals and communities.
