There’s a lot of conflicting information about the content of vaccines. For example, vaccines containing mercury. The information circulating can be more incorrect than true. Actually, what are the main ingredients of the vaccine? Is there really mercury? You need to find out the facts below.
What Does A Vaccine Contain?
The main content of the vaccine is commonly called the active ingredient. The active ingredient is an ingredient that will stimulate the activity of the immune system so that it is better able to fight diseases. The vaccine, which aims to preserve the human immune system, also contains several other ingredients such as water.
The main content of the vaccine is viruses or bacteria. Why is the virus or bacteria injected into the human body? Relax, you don’t have to worry, these viruses and bacteria are already weakened. Later, when the weakened germs enter the body, you will not get the disease. Instead your immune system is getting stronger.
Because, your immune system already recognizes the seeds of this dangerous disease through vaccines so that one day when the original disease seeds enter the body, you are immune to the disease.
Vaccines are produced to produce maximum benefits for the human body. Some of the active ingredients as vaccine content are made by taking part in viral DNA, and inserted into other cells to be active. This combination of DNA and virus is effective in preventing some infectious diseases.
Some vaccines, which content has been combined with other viruses or bacteria, namely hepatitis vaccine. The vaccine uses hepatitis B viral DNA and other cell DNA. Later this combination will produce protein. This protein is the active ingredient of vaccine content that will prevent hepatitis.
Vaccine components List
Vaccines contain various antigens, including antigens, stabilizers, adjuvants, antibiotics, preservatives.
Vaccines can also contain residues from the production process. Knowing exactly what is in one type of vaccine will be able to help in the investigation in case of AEFI. And it can also be to help to look for other vaccine options if a person is allergic to one of the suspected components of the vaccine.
Antigens are components produced from the structure of disease-causing organisms known as “foreign body” by the human immune system. This antigen can stimulate the formation of immunity.
Stabilizers are used to ensure the stability of the vaccine when stored. Stability is essential when stored in a bad cold chain system. Instability can cause loss of antigenicity and decrease infection with live vaccines (LAV).
Factors that affect the stability of the vaccine include, temperature, pH. Unstable bacterial vaccines are caused by hydrolysis or aggregation of carbohydrate and protein molecules. Materials used as stabilizers include MgCl2 (for OPV), MgSO4 (for measles vaccine), lactose-sorbitol and sorbitol – gelatin.
Egg Protein (Ovalbumin)
Egg allergies are very common in children under 5 years of age, and are much more common in children than older persons. Even so, for those of you who have an egg allergy, using a vaccine containing eggs is safe because the ovalbumin content is very low.
Ajuvants are added in vaccines to stimulate the formation of antibodies against antigens in the vaccine more effective.
Many vaccines contain aluminum salts such as aluminum hydroxide, aluminum phosphate or potassium aluminum sulfate. They act as adjuvant i.e. Strengthen and prolong the immune response to the vaccine.
The content of vaccines such as aluminum salts seems to slow the release of the active ingredient of the vaccine after it is injected and stimulates the immune system to respond to the vaccine. Even so, you don’t have to worry because there is very little amount of aluminum in the vaccine.
Vaccines containing aluminum are associated with the appearance of redness in the injection area compared to other vaccines.
Antibiotics (in small quantities) are used in the process of making vaccines, with the aim of preventing bacterial contamination of cell cultures where the virus is being bred.
Usually antibiotic levels detected in vaccines are very low, for example, in MMR and IPV vaccines, there is only 25μgr neomycin for each dose of vaccine (< 0.000025 gr). People who are allergic to neomycin should be closely monitored, as an allergic reaction may arise, so that it can be treated quickly in case of allergies.
MF59 (Squalene Oil)
The next vaccine content to be found is MF59. MF59 is an ad-ingredient for vaccines to make it more effective. This auxiliary ingredient strengthens and prolongs the immune response to the vaccine.
Preservatives are added to vaccines with multi dose packaging to prevent the growth of bacteria and fungi. There are several types of preservatives such as thimerosal, formaldehyde and phenol derivatives.
