What Vaccines Do
Vaccines must produce an immune response, which is a reaction in your body that will protect you from the disease. The only way to cause a natural immune response is to use what naturally causes a response. What naturally causes a response are the very things that make us sick. These “things” are the microbes (viruses, fungi, and bacteria) that lurk everywhere in many shapes and forms.
Why Vaccines Are Made
The body takes time to respond to microbes that enter our bodies every way imaginable. They can be breathed into our lungs, swallowed, enter through our eyes, skin, wounds, etc. White blood cells will detect them in time, but often after they have begun to use our body to make more of themselves and spread throughout our system and back outside of our body to others. Our body will have white blood cells to fight the microbes once the white blood cells start to get produced by our body, but it takes time for them to be produced. The best white blood cells are ones that are made to fight a specific microbe. Those specific white blood cells take the longest to make, but work the best. The body also retains memory cells afterward to launch a specific immune response if the same microbe is detected in the body again. That is why we seem to only get sick with some diseases only once.
It is better to build a specific immune response with the weak or dead microbe or microbe parts. Otherwise, the damage caused by the strong microbe before the body can respond can lead to permanent damage or death. Vaccines prevent damage, death, and the spread of diseases because the memory cells cause the body to react to a dangerous microbe quickly before it can make more of itself in our body.
There are billions of microbes that can make us sick. Some make us sicker than others because of what they do when they enter our body. Very few vaccines are made compared to how many microbes can make us sick. Vaccines are only made to protect us from the most harmful microbes. There must be something present in the vaccine to cause the body to build a specific memory cell against the next time the harmful microbe is detected in the body.
How Vaccines Cause Immunity
When making vaccines they use the microbes, or microbe parts, to cause the immune system to mount the desired immunity. The parts of the vaccine that cause the immune response are called antigens. Antigens are simply any substances "foreign" to the body (not produced by the body). Antigens that replicate (live entities that can make more of themselves using the invaded host body) pose a particular, repeatable threat. These antigens include microbes (like bacteria & viruses) and other parasites. The immune response causes antibodies to be made by the body after other white blood cells find the antigens.
This immune response to vaccination is exactly the same as the immune response to any other type of exposure to antigens that the body encounters every day. Therefore, the immune system or immune response is not weakened in any way.
Vaccinations can be introduced orally (by mouth) or by injections (by needles) depending on the type of vaccine. Vaccinations can be weakened or inactivated/dead forms of the microbe that would cause diseases, or they can be just parts of the microbes that will still result in the same immune response to the active or live form of the microbe.
Once the antigen is introduced, then your body will detect it with a type of white blood cells called B lymphocytes. The cells will replicate in response to the detection (clone an army of B lymphocytes). The newly formed B lymphocytes will then become either plasma cells or memory B cells.
Plasma cells will produce the antibodies to bind to the antigens. It takes 14 days for the antibodies to reach a maximum concentration in the blood.
Memory B cells will live on (remain dormant in the body) after the antigens are removed and will cause a quick response once the antigen is encountered again. Memory B cells are the primary reason for vaccination. They are antigen specific and will prevent infection when that antigen is encountered again.
The reason why immunization saves lives is because the body is able to build up Memory B cells before being harmed by an actual live/strong replicating microbe during the first part of the immune response (before there are any memory B cells). An army is made and standing in wait for any invading disease causing microbes, including bacteria and viruses. The army can knock it down before it can make a person sick.
Without this army, an invading microbe will have a chance to make millions of itself by using the cells and body's resources. A virus will turn a body's cells into virus factory, and infected persons will spread them to others. The body’s cells that are "eaten" by bacteria or used by viruses will no longer be free to do their jobs within the body. This cellular destruction by microbes, and the resulting immune response are what are seen on the outside as an illness. Vaccination prevents illness and the spread of diseases.
How Vaccines are Made
The microbes that we want to be protected against must be grown in mass amounts to get what we need for the body to react to them. The body must be fooled into thinking that it is being infected, but does not view impending infections equally. Sometimes the microbe must be alive before the body will respond. Sometimes it can be dead, but still whole. Other times just a part of the microbe will cause a full scale immune response. Different strategies will determine how strong the immune response is, and how long it lasts. Everyone’s immune system is also different. What may work for one person may not work for anther. A vaccine must cause an immune response in the majority of people. Therefore, we get vaccines where multiple doses are needed before most people build up a permanent immunity.
Viruses that infect humans must be grown in ways that they prefer to live in. Influenza vaccines can be grown in chicken eggs. Vaccines that only need parts of viruses can be made by fooling plants into growing those parts. Two of the six various ways to make the most common vaccines are outlined below:
Live Viral Vaccines
Vaccines like the MMR vaccine (Mumps, Measles, Rubella), are live vaccines. They never contain preservatives that would kill the microbe because the body won’t react to the dead forms of the viruses. These vaccines often must be refrigerated and have specific expiry dates. These viruses originally grow the best in warm bodies, so if you grow some viruses in a cold place (like a refrigerator), then the viruses will adapt. This means that only the viruses that survive the cold will live on to produce more viruses that now prefer the cold environment. If you put the cold-loving viruses in a warm human body, then they will be weak and unadjusted the warmth. This ensures that our bodies will have time to build up immunity before they have a chance to make more viruses that prefer the warmth. It can take up to 10 years to get a good stock of changed viruses that are safe to use as immunizations. The original viruses in current vaccines came from an infected living child in 1954. Other ingredients (amino acids, sugar) are contained along with water in the vaccine to act as a buffer, but they are unable to replicate. An antibiotic is used (neomycin) to prevent the growth of harmful microbes in the vaccine.
Dead Viral Vaccines
The diphtheria, polio, and pertussis (DTaP) vaccines used today are grown in tissue cultures and then killed. Tissue cultures are required because polioviruses need specific cell parts (dna) to replicate with. The viruses are heated or killed in formaldehyde. Formaldehyde is formed in our bodies every day when we digest protein, but it can kill microbes. The amount of formaldehyde that remains in vaccines is nowhere near the amount that is produced in our bodies everyday when we digest protein (in dairy, meat, breast milk, etc.). Another ingredient is an aluminum salt (the same kind used in antacids and cake mixes), but the dose is still under what is ingested every day in food sources. Saline makes up the bulk of this vaccine apart from the dead viruses.
More vaccine making processes can be found at the PBS website:
Why are Vaccine Combined?
This question is well explained by others, like NEAL A. HALSEY M.D. :
The human immune system is remarkable in its capacity to respond to millions of different antigens. Children are exposed to many thousands of bacteria, fungi and viruses beginning at the moment of birth. In the first few months of life the human immune system responds to many foreign antigens from these organisms. Each bacterium contains hundreds of different antigens including carbohydrates, fatty substances, proteins, RNA and DNA. Children develop antibodies to 17 different proteins in one common bacterium (Moraxella catarrhalis) and a strep throat infection results in immune responses to 25-50 different antigens.1 Some new highly effective vaccines are made using only one or two bacterial antigens. For example, Haemophilus influenzae type b vaccines, or Hib as they are commonly called, contain only a single bacterial antigen attached to a protein. Children immunized with these vaccines are protected against meningitis and sepsis caused by the Haemophilus influenzae type b organism. Therefore, the immune systems of children who receive this vaccine are exposed to far fewer antigens than children naturally infected with the bacterium. Since all children would be exposed to the bacterium if they were not immunized, the use of the Hib vaccine actually reduces the burden on the immune system.
Children's immune systems are tested every time they eat or breathe. There is NO plausible separate test to see if their bodies can "handle" vaccines, since their bodies handle antigens every minute of every day, and vaccines are just another antigen. As in the above quote, vaccines are even LESS of a burden on the immune system compared to the actual disease-causing antigens like the ones that are in the air that everyone breathes every day.
Please STOP listening to Jenny McCarthy. Not understanding why there are viruses in vaccines and why her other ideas are not valid indicates that she has much to learn. Other parents see the same kinds of improvement over time in their children, and it seems Ms. McCarthy is unable to consider that is a possibility for her own son if she had not spent all that money on diets and expensive unproven therapies.
People that really want to help parents don't make them take out exorbitant loans to pay for them.
Analyze the Issues
Continued studies attempt to lay the claim that vaccines cause autism to rest. However, some parties will never be convinced, no matter how the studies are done and what they show. We're of the opinion that the sales of autism cures keep the arguments coming. Money continues to be spent on these studies to address continued claims, but doing more and more studies seems to just give the autism cure groups a chance to claim that studies are done because there is a link (even though every good study done keeps showing there is no link).
However, this circle of claims keeps bypassing the one question that the people making claims that vaccines cause autism can't answer. How? How would vaccines cause autism? There is no reason. Vaccines cause a natural reaction in the body that causes immunity, not autism. This reaction happens every day, all day long in all of our bodies as antigens enter through the skin, nose, eyes, etc.
We encounter the minerals (aluminum salts) used in vaccines every day because they occur naturally in our food and water. They are safely used as ingredients in cake mixes, deodorant, antiperspirant, and other every day items:
"Aluminum is a very abundant element in our environment. It is in many foods we eat, many personal hygiene products we apply to our skin (deodorants, for example), and many medicines we ingest. Thus, all infants are exposed to aluminum in the environment. Breast milk, for example, contains approximately 40 micrograms of aluminum per litre, and infant formulas contain an average of approximately 225 micrograms of aluminum per litre."
Even people trying to go "all natural" for their food sources still get the same doses of these minerals in their "natural" food and water sources. Aluminum and other minerals are a natural part of our world. Even water can kill us if we drink too much of it at once. Water is also a chemical. The claims that vaccines are poisonous are simply not true. People can say the same about the water, but you have to drink far more water than could ever be used in vaccines before it will kill you.
There are a great number of people claiming that we are all being constantly poisoned to death by chemicals and preservatives. When asked if water is a chemical, these people say no. A simple high school course in chemistry would show them why water is a chemical, and at what dose in what period of time will kill a person. Anything can kill us in large amounts, so we must learn to examine the claims made by others and ask why they make these claims.

All in the Label
(In the 1990s there was a change in diagnostics.In the 1990s, the autism umbrella expanded, and autism is now shorthand for a group of milder, related conditions, known as "autism spectrum disorders."The spectrum includes Asperger's syndrome and something called PDD-NOS [for Pervasive Developmental Disorder-Not Otherwise Specified].)
Different Diagnostic Criteria and Prevalence Vs. Incidence (Numbers can be skewed because children living in some areas are more likely to be seen by specialists than are others, and children with some health plans are more likely to have coverage for specialists than others.)
