Through the years, misconceptions of vaccines have not yet died down. Some believed that it poses a greater risk than being helpful, however, over the past years, vaccines have reduced and diminished infectious diseases.

The following misconceptions of immunization should be corrected:

  • Vaccines can cause autism
  • The immune system of an infant can’t handle the vaccines.
  • Natural immunity is better.
  • Vaccines contain toxins.

There is a line that links exposure and immunity, this was discovered when they used the antibodies to resist the infectious disease. During the 19th century, the laboratory made vaccinations was produced by the discovery of Louis Pasteur on the diseases.

As the mechanism of actions of the vaccines is not fully appreciated, it works to determine and defend the body against pathogens. For this to be achieved, there are blueprints of the pathogens, called antigens, introduced into the body to trigger the response of the immune system. The immune system can recognize the foreign invaders and produce antibodies that kill the pathogen before it can spread.

Scientists have made different types of vaccine:

Live attenuated vaccines: The immune system is introduced with a form of a pathogen that is weaker and asymptomatic. This is an excellent stimulant for the immune system, however, it is contraindicated in people whose immune system are compromised.

Inactivated vaccines: The immune system is introduced with dead cells of the pathogens that are killed by chemicals or heat. It is safer, however, it does not have an accurate simulation.

Subunit or conjugate vaccines: A specific carbohydrate that comes from the pathogen is introduced into the body which trains the immune system not to provoke the sickness. There is a lesser chance for adverse reactions but only certain vaccines can be prepared in this method.

Toxoid vaccines: Dead toxins mixed with water and formaldehyde is introduced into the body which makes the immune system kill living toxins.

Conjugate vaccines: Sugar molecules are being attached to a recognizable pathogen to help the immune system determine bacteria or viruses that are coated with sugary camouflage.

DNA vaccines: When injected, it instructs the immune system to create antigens that can fight off the pathogen all by itself.

Recombinant vector vaccines: A harmful antigen is introduced into the body that triggers the immune system to produce antigens that can determine and fight off foreign invaders.

There are vaccines being recommended in three schedules: 0 to 6 years old, 7 to 18 years old, and adults 19 years and older.

People should not be worried and hesitant in receiving vaccines, there are adjuvant added to improve the response of the immune system. These ingredient components are antibiotics, stabilizers and preservatives, these are necessary to prevent fungal or bacterial contamination.

Although health organizations are distributing vaccines which led to increased access to immunization programs, a reduction of 79% from the fatalities was made. While these existing immunization vaccines are being distributed, they are being improved. Moreover, they are working on a new set of vaccines that fights cancer. It is created to train the body to fight cancer in its early stages of development.
