How do Vaccines Work

Vaccines are an acquired immunity provided to the body.  The vaccines are given to make a competent immune system of our body.  They are given to you, to prepare your immune system in advance to fight against some of the deadly or infectious illnesses.  Through, vaccines our body codes about certain disease, and once the vaccination is done the body learns about a particular bacteria, virus or toxins and can easily defend the same.

Why do you need vaccines?

In the vaccination, the pathogens are introduced to the body.  This pathogen is the same, which can cause the disease.  The same is introduced through the injection, nasal drops, or oral formulations.  After the introduction, vaccines or the pathogen our body produce antibodies, and kills the pathogen. To add, whenever any similar live and active pathogen enters in the body, the body can produce the same type of antibodies and protect us from the disease. At times the vaccines boosters are induced from time to time so that our body gets the perfect reminder of the pathogens.

Discussion about vaccines

During the vaccinations, either vaccine are given  in the form of dead or inactive form of microbes, or sometimes it is infused as a form of weak or attenuated form of virus.  These pathogens or antigens trigger the immune system to fight against the same. In the meanwhile, the body creates templates, and the key to the same lock induced.  Therefore, the same key acts for the active or wild antigens and prevents you to get sick. You might be wondering about if vaccines make you sick or not.  No, vaccines do not make you sick, if you have healthy immune system.  However, if one has any serious or complicating disease, then they must consult doctors.  In the case of attenuated vaccines, sometimes are reported with temporary illness. Therefore, you are advice to consult before taking attenuated vaccines, even if your immune system is healthy.  Vaccinations are very effective since they prevent many of the bacterial or viral infections.  For instance, polio, flu, measles etc. are easily combated with such vaccinations.  In the recent releases by centers for disease control and prevention, now vaccines are given for many of the viral infections. These vaccines are given against hib, against some serogroups of N.meningitdis and various types of streptococcus pneumoniae. These vaccines are very influential and safer of patients in the normal health.

Let me explain you what is hib and streptococcus pneumoniae. Hib is a kind of bacteria which is also known as haemophilus influenza, type b. this bacteria is responsible for many of the bacterial infections, like bacterial pneumonia, cellulitis.  To combat with the disease like pneumonia, there are vaccines like streptococcus pneumoniae. Other bacteria include N. Meningitides that causes the fatal disease like meningitis. However, the same is also, repeated with the viral infections also.
