Are Vaccines Dangerous To Health?

Vaccines are an achievement of medical research and have dramatically improved the quality of life in populations worldwide. However, currently there are controversial opinions regarding its use. In this article we will be clarifying doubts regarding the safety of vaccines.

Vaccines

There are different types of vaccines:

  • V acunas toxoids:  contain a toxin or chemical produced by the bacteria or virus. It has local effects and immunizes against the viral or bacterial agent. Some examples are the diphtheria and tetanus vaccines.
  • Killed (inactivated) vaccines: these are created from fragments or molecules that come from the pathogenic agent. An example of this is the pertussis vaccine.
  • Live virus vaccines: they use the virus that caused the disease, but weakened. Examples: measles, mumps, and chickenpox vaccine.
  • Biosynthetic vaccines:  Scientists use artificial substances that mimic fragments of pathogens. Such is the case with the hepatitis B vaccine.

Many infections cause irreversible disorders in the body, especially in the case of the smallest. That is why in different countries vaccination campaigns have been implemented for the immunization of children.

However, there is a doubt in several population sectors that vaccines can be harmful.

Are vaccines safe?

  • If your immune system is weak, you should avoid live virus vaccines such as influenza, measles and mumps, as you run the risk of suffering an infection.
  • In the event of an allergic reaction or any discomfort after the application of vaccines, go immediately to the doctor.
  • Accept only vaccines that come from recognized pharmaceutical companies, do not risk your family using unknown products that can be dangerous.
  • According to Dr. David Ayoub, an American specialist, the vaccines against hepatitis A and B, diphtheria and tetanus contain aluminum and mercury. These metals can be counterproductive in the development of children and even toxic. If in doubt, ask a specialist about the components of the vaccine that you will receive.
