With the rise of Covid-19 infamously, which took the world by surprise with massive pandemic around the globe we begin more and more familiar with the words Vaccine and the talk of the town about how does the vaccine work. So, let’s take a look a little bit closer.

When Mother Nature decides to release a new disease widespread into the world, Mother Nature also hints “There will be Vaccine”. So, what is a vaccine, to begin with? A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. It is a type of medicine that trains the body’s immune system. A vaccine stimulates your immune system to produce antibodies so that it can fight a disease it has not come into contact with before. Vaccines contain the same parts of a particular organism (antigen) that cause disease, but they have been either killed, inactive or weakened to the point that they don’t make you sick or harm you.

It’s been a long argument about what’s in a vaccine, what is the ingredients to make a vaccine? is it safe? according to the official WHO (World Health Organization) site here is the list of what is in the vaccine are :

  1. The antigen. This is a killed or weakened form of a virus or bacteria, which trains our bodies to recognize and fight the disease if we encounter it in the future.
  2. Adjuvants, which help to boost our immune response. This means they help vaccines to work better.
  3. Preservatives, which ensure a vaccine stays effective.
  4. Stabilizers, which protect the vaccine during storage and transportation.

However, many of the components used in vaccines occur naturally in the body, in the environment, and in the foods we eat. Like we said early on, Mother Nature provides and hints “there will be vaccine” to all new pathogen and diseases. Some are just not been discovered yet. All of the ingredients in vaccines, as well as the vaccines themselves, are thoroughly tested and monitored to ensure they are safe.

Vaccines work by training the immune system to recognize and fight pathogens, both viruses, and bacteria. For example, Covid-19 is a new kind of disease, so our body’s immune system doesn’t recognize how to fight or terminate it. with the vaccine developed today, our immune system introduces to this new pathogen that already inactive or weakened. Each antibody in our system is trained to recognize one specific antigen of this new pathogen. Once it recognizes the antigen, our body will produce specific antibodies.

Once the antigen-specific antibodies are produced, they work with the rest of the immune system to destroy the pathogen and stop the disease.

According to WHO (World Health Organization) “Our immune systems are designed to remember. Once exposed to one or more doses of a vaccine, we typically remain protected against a disease for years, decades, or even a lifetime.” WHO also includes steps of how generally Vaccines work, such as :

  1. Recognizes the invading germ, such as the virus or bacteria.
  2. Produces antibodies. Antibodies are proteins produced naturally by the immune system to fight disease.
  3. Remembers the disease and how to fight it. If you are then exposed to the germ in the future, your immune system can quickly destroy it before you become unwell.

That is why vaccination is so important. Rather than treating a disease after it occurs, vaccines prevent Us in the first instance from getting sick.
