In clinical terms, a vaccine is a product that triggers an individual’s immune system. It helps to increase the person’s immunity towards specific diseases and also protects the person from the ailments. Also, a vaccine is generally administered via a needle injection and can also be administered through the mouth or nose.
Life-threatening epidemics such as smallpox that claimed millions of lives have now been completely eradicated thanks to effective vaccination. So, the difference between immunisation and vaccination lies in the fact that a body can only develop immunity when it is properly administered with a vaccine.
However, an individual's immunity can also be increased by natural means. For instance, a person who suffered from chickenpox or measles is unlikely to contract it again. A person becomes immune thanks to the creation of antibodies in his or her system. This is done by exposure to weak or deactivated forms of microbes. This is also known as inoculation.
Which of the following diseases has no vaccines?
A vaccine does not cause disease when administered. It is merely a modified version of an immunogen and may consist of either an entire pathogen, a toxin or just some of its components. More so, it only causes a healthy individual to elicit an initial response to the pathogen and generate many memory B and T cells.
Vaccines ensure protection to everyone and help generate communal immunity. Though vaccines and immunisation are essentially part of one process, they are quite different in what they mean.

1. What is the Difference Between a Vaccine and an Immunisation?
Ans. A vaccine is usually administered through a needle or orally. It may also be sprayed through the nose. It enhances the body's immunity.
Immunisation is not administered – it is the body’s natural way to fight diseases by triggering the immune system.
2. Are Vaccines Completely Effective?
Ans. Vaccination does not ensure complete protection from disease. For instance, the vaccine called Imovax Rabies only provides resistance from rabies. It does not guarantee that a person will not be infected by it if exposed to the microbe.
3. What is an Immunisation?
Ans. The World Health Organisation defines immunisation as the process which helps make an individual immune to a specific infectious disease. This is done by administering a certain type of vaccine.
