Adaptive Immunity is the protection that we get from being exposed to specific pathogens (microorganisms that correlate with a specific disease or set of symptoms) throughout our lives (not just in childhood) or when we are vaccinated against them. Keep in mind that vaccination and immunization are NOT the same thing. You can be immunized with a pathogen without being vaccinated and just because you have been vaccinated does not mean you are immunized for life.
Let me explain.
The term immunization only means to make someone immune to something whereas a vaccination is specific immunity created from injecting or administering specific suspensions of attenuated or killed microorganisms. So technically vaccinations are immunizations but that is not the only thing that can immunize the body and provide protection.
Immunization most typically comes from natural exposure to pathogens that lead to a disease. This type of immunity develops over time and at the beginning of life is not really present because baby hasn't been exposed to much yet. This presents a big problem for newborns and therefore is why babies get sick easily- their protection slate is clean if you would. Therefore, in order to be somewhat protected, babies rely on their innate immunity and what is passively passed from mom through the placenta while in the womb and through breastfeeding when in the outside world. As baby gets exposed to more pathogens and builds immunological memory, the breast milk changes in consistency to continue to allow proper support for future exposures to the same and new pathogens; all the while the baby is building its own immunological memory from the things it is exposed to on its own (and this includes allergens along with toxins, bacteria, and viruses).
Pathogens that enter the nose and mouth (by either breathing or eating something or putting hands/things in the mouth) pass by the tonsils, which were previously thought to work similar to lymph nodes in that they are a battleground for immune system cells to fight and kill pathogens but in actuality, tonsils are really monitors of what is coming into the body. Meaning they take a sample of what is entering the body and prime the immune system for what is coming (an advantage to fight off germs better and faster).
Injected vaccinations skip this step as well as skip the detoxification channels of the body because the concoction is injected directly into the blood stream and goes directly to our vital organs, drowning them in toxins and foreign material (man-made full on pathogens or just parts of pathogens) which makes it harder on the body to mount a normal immune response. Instead, the body does not know how to react to the ingredients in vaccinations (both the pathogens and adjuncts) and leads to an abnormal immune response that sometimes can harm the body more than it helps. Especially if the body is already in an unhealthy state to begin with.
Natural immunization or immunity occurs only after recovery of a infection with the formation of memory immune system cells as a result of the second line of immune system defenses being activated... the white blood cells. As the body is exposed to the same pathogens over and over, the immune system response gets better and better and faster and faster at identifying and eliminating the microorganism because these memory cells are now circulating in the body, all ready to go.
Of course certain pathogens, like the ones that are correlated to measles and chicken pox, create lifetime immunity, meaning you won't get these diseases more than once if exposed and infection occurs (remember disease and infections only happen if the defense systems of the body are compromised by not providing your body with its requirements). But this is only the case if you are exposed to those microorganisms naturally or the wild-type. Vaccinations do not give you this lifetime immunity hence why boosters are necessary at certain intervals. Side note: exposure to some pathogens naturally actually has certain health benefits (yes benefits) depending on the microorganism. For example, natural contraction of the measles virus that results in an infection has been shown to have anti-heart disease and anti-cancer effects.
What limits natural immunization?
Not breastfeeding (pumping and bottle feeding with formula and breast milk)- no passive immunity provided by mom who has already formed memory immune system cells.
Kids not getting exposed to pathogens- over clean environments, not being around people, not being able to play outside and get dirty, staying away from other sick kids...
Vaccinations (as discussed)
Removal of any lymphoid tissue (bone marrow, spleen, thymus, tonsils, lymph nodes and vessels, and mucosa-associated lymphatic tissue or MALT which includes the appendix and Peyer's patches in the intestinal wall)- immune system cells won't be formed, mature, or function properly.
Subluxations- decrease nerve flow to lymphoid tissue and blood supply which can affect the entire process.
Toxins- pollution, personal care products, plastic use, vaccinations... bog down the lymphoid tissue and decrease the reaction time of the immune system cells.
Using over the counter or prescription medications to take care of symptoms- decreases or prevents the destruction and elimination step (effectively lengthening the healing process- takes longer to recover because the pathogens are still present in the body).
Bad nutrition- processed food, not eating enough fruit and vegetables, pesticides, GMOs... lack of nutrients affects the entire process because the nutrients are necessary for energy and building blocks of immune system cells.
Not exercising- lack of oxygen diminishes the power and effectiveness of the immune system cells which could affect the entire process.
