What are vaccines and what exactly do they do?

by Sean Martu

Recently my aunt called me and was trying to convince me of the importance of taking vaccines. She’s not one to listen, so I decided to write a blog post on what vaccines are and what they do because there is a huge popular misconception as to what vaccines do and to what degree of protection one receives from viral pathogens.

How does our body fight invading pathogens?

Harmful germs are all around us all the time, both in our environment and in our bodies. When an individual is susceptible and they encounter harmful germs, it can lead to disease and death.

The body has many ways of defending itself against pathogens (disease-causing organisms). Skin, mucus, and cilia (microscopic hairs that move debris away from the lungs) all work as physical barriers to prevent pathogens from entering the body.

When germs, such as bacteria or viruses, invade the body, they attack and multiply. This invasion, called an infection, is what causes illness. The immune system uses several tools to fight infection. Blood contains red blood cells, for carrying oxygen to tissues and organs, and white or immune cells, for fighting infection. These white cells consist primarily of macrophages, B-lymphocytes, and T-lymphocytes:

  • Macrophagesmedia icon are white blood cells that swallow up and digest germs, plus dead or dying cells. The macrophages leave behind parts of the invading germs called antigens. The body identifies antigens as dangerous and stimulates antibodies to attack them.
  • B-lymphocytes are defensive white blood cells. They produce antibodies that attack the antigens left behind by the macrophages.
  • T-lymphocytes are another type of defensive white blood cell. They attack cells in the body that have already been infected.
How do vaccines work?

Vaccines help develop immunity by imitating an infection. This type of infection causes the immune system to produce T-lymphocytes and antibodies. However the vaccine is not supposed to cause illness, but that is not always the case, as sometimes after getting a vaccine, the imitation infection can cause minor symptoms, major symptoms, and on rarer occasions death. But such minor symptoms are normal and should be expected as the body builds immunity.

Once the imitation infection is subjugated, the body is left with a supply of “memory” T-lymphocytes, as well as B-lymphocytes that will theoretically remember how to fight that disease in the future. However, it typically takes a few weeks for the body to produce T-lymphocytes and B-lymphocytes after vaccination. Some vaccines require multiple doses, given weeks or months apart. This is sometimes needed to allow for the production of long-lived antibodies and the development of memory cells. In this way, the body is trained to fight the specific disease-causing organism, building up the memory of the pathogen so as to rapidly fight it if and when exposed in the future.

Therefore, it is possible that the vaccinated individual infected with a disease just before or just after vaccination could develop symptoms and get the disease because the vaccine has not had enough time to provide protection.

Types of vaccines

Vaccines contain weakened or inactive parts of a particular antigen(harmful pathogen) that trigger an immune response within the body. Newer recently government-approved for use and more controversial vaccines such as the mRNA covid-19 vaccines contain the genetic blueprint for producing antigens within the human cells by combining with the cells’ RNA to create the antigen.

Here is a list of other more common vaccines given to children in the USA:

  • Live, attenuated vaccines fight viruses and bacteria. These vaccines contain a version of the living virus or bacteria that have been weakened so that it does not cause serious disease in people with healthy immune systems.
  • Inactivated vaccines also fight viruses and bacteria. These vaccines are made by inactivating, or killing, the germ during the process of making the vaccine.
  • Toxoid vaccines prevent diseases caused by bacteria that produce toxins (poisons) in the body. In the process of making these vaccines, the toxins are weakened so they cannot cause illness.
  • Subunit vaccines include only parts of the virus or bacteria, or subunits, instead of the entire germ. Because these vaccines contain only the essential antigens and not all the other molecules that make up the germ, side effects are less common.
  • Conjugate vaccines fight different types of bacteria. These bacteria have antigens with an outer coating of sugar-like substances called polysaccharides. This type of coating disguises the antigen, making it hard for a young child’s immature immune system to recognize it and respond to it.
Harmful ingredients in vaccines?

Aluminum – used in some vaccines and excess aluminum in human bodies can cause neurological harm.

Formaldehyde – also found in some vaccines, is a carcinogen, and, according to VaxTruth.org, exposure can cause side effects such as cardiac impairment, central nervous system depression, “changes in higher cognitive functions,” coma, convulsions, and death.

Glutaraldehyde – a compound used to disinfect medical and dental equipment, is used in some DTaP vaccinations and exposure can cause asthma and other respiratory issues.

Cetyltrimethylammonium bromide (CTMB), a compound used as an antiseptic, which can be a skin, eye, and respiratory irritant.

2-phenoxyethanol – an antibacterial that is a skin and eye irritant that can cause headache, shock, convulsions, kidney damage, cardiac and kidney failure, and death. Some vaccines for the flu contain chicken egg protein, which can be harmful to children who are allergic to eggs.

Yeast proteins – Some vaccines for PCV, HPV, DTaP, Hep A, Hep B, and Hib contain yeast proteins which, according to VaxTruth and Joseph Mercola, MD, an alternative medicine proponent, contain MSG that can cause migraines, irritable bowel syndrome (IBS), asthma, diabetes, Alzheimer’s, Lou Gehrig’s disease, ADD, seizure, and stroke.

Thimerosal – an ethyl mercury-containing preservative in some multi-dose preparations of influenza vaccine, could cause mercury poisoning either in children or affect the unborn children of pregnant women who receive this vaccine. The preservative was more popularly believed to cause autism in children.

Thimerosal is no longer contained in any vaccines meant for children.

A statement issued by the American Academy of Pediatrics and the US Public Health Service in 1999 prompted the removal of thimerosal from many vaccines. In 2004, the Immunization Safety Review Committee of the Institute of Medicine rejected the hypothesis of a causal relationship between thimerosal-containing vaccines and autism.

My view on vaccines

Vaccines do not make you invulnerable to disease, nor do they stop you from being infected or spreading the disease. What a vaccine is supposed to do is give you a better chance at fighting the disease off, while not developing serious symptoms or succumbing to death.

Historically speaking, vaccines were first introduced by an enslaved African man in the Americas. He had taught the individuals who had enslaved him how to inoculate themselves from smallpox.

I agree with vaccines in principle and theory, but where I draw the line is the harmful ingredients they contain, and also the methodology of application with many of them. The other aspect I disagree with is that vaccines have become a machine for enriching pharmaceutical corporations. So whether components within vaccines cause autism or not, you’ll never know the truth from the pharmaceutical industry-sponsored studies, nor from the pharmaceutical industry-controlled federal agencies, because there is too much money at stake.

It doesn’t help that with these new mRNA vaccines that large social media platforms such as Youtube, Facebook, and Instagram are censoring and deleting data or information from individuals who are reporting a differing narrative, or harmful effects they are experiencing from these vaccines.

Lastly, I approach disease holistically. I don’t see the point of giving the immune system a “memory” of a particular pathogen, to potentially fight it in the future, if the majority of people have compromised or weak immune systems because of nutritionally deficient food, and harmful and poisonous food additives, preservatives, and chemicals that the same FDA approved for human consumption.

What happened to strengthening the immune system with wholesome nutrition, and removing the heavy metals and chemicals lodged in our intestines and livers which are weakening our immune system?

Then we are back at square one, is there even wholesome nutritious food in America? From my research no, all of the commercial farm soils are nutritionally deficient, especially of magnesium and silica, the soils are also poisoned with repeated use of herbicides and pesticides.

What I see is a hamster wheel of food & pharmaceutical drugs that makes us sick, and a never-ending flow of billions of dollars going into the pockets of those same corporations poisoning us with the food and drugs. But we’re joyfully and knowingly running on this hamster wheel, gleefully ignorant of what is going on, daily imbibing and filling our mouths with poison.

Everyone is getting sicker, cancer is proliferating more and more, people are developing diseases at a much younger age, people are working longer for less, and the work is deteriorating their minds and bodies.

The end result is to try and buy your Freedom after a lifetime on the hamster wheel when you no longer have a life, and you’re addicted to unaffordable pharmaceutical drugs, and your body has lost most of its basic functions… they call it retirement.

Can you post about the difference between a vaccine and the flu shot?

You get a polio shot once in your life. It lasts a lifetime. You’re recommended to get a flu shot every year because it’s a different flu every year. Getting a shot every year, with all of the nasty ingredients that you mention, adds up. Now, they want us to have a flu shot and a COVID shot and COVID booster shots.

The flu shot is a vaccine, but you only get vaccinated for one variant of the flu, every year there are “new” mutations to the flu, so every year they sell you new vaccines for the flu.

There seems to be a couple of proofreading errors in your paragraphs. For CTMB and 2-phenoxyethanol, you didn’t finish out the rest of the sentence. Just a little heads up

Thanks for looking out, I have no idea how that happened, but it’s all corrected now.
