Vaccination and Immunization, although similar in context, hold different meanings. A vaccine is essentially given to a person to develop their immunity towards a particular disease. For instance, a child without a measles vaccine is susceptible to the disease. The vaccine helps in building resistance or immunity to the disease.

How do Vaccination and Immunization Differ?
Vaccination and immunization are two sides of the same coin. Immunity can occur naturally or can be induced artificially. For example, an individual who has suffered from mumps generally doesn't get it again, as their body has developed immunity. Artificial immunity, on the other hand, is achieved by exposing the body to weakened or deactivated disease-causing microbes . Below are some key differences between Vaccination and Immunization:
| Differences Between Vaccination And Immunization | |
| Vaccination | Immunization |
| Vaccination involves using vaccines to initiate an immune response to guard against diseases. | Immunization is the process of making an individual resistant to a disease, typically through vaccination. |
| Vaccines are usually injected or administered orally. | Immunization is not administered. It's the body's own response to vaccines. |
| Twinrix is a commonly known hepatitis A and B vaccine. | The body builds up immunity against hepatitis A and B through this vaccine. |
| Vaccination does not provide absolute resistance to a disease. | Full immunity is achieved when the person recovers fully from the disease. |
| If a microbe mutates, it may render the vaccine ineffective (this is why there's no vaccine for the common cold). | Similarly, disease variations can affect the body's ability to generate an immune response. |
Conclusion
While Vaccination and immunity are often used interchangeably, they are distinct terms with different implications.
