Hi @suesa, you know me so I hope you're not suprised that I don't think vaccinations are good for your immune system. I'm not talking about all vaccinations! I'm just affraid that:

• injecting is not a natural way for any disease to enter the body
• the EPA warns the amounts of aluminum in some vaccines grossly exceeds that what is in vaccines and what's worse they are looking at oral intake! Injection is again, far worse.
• It is also very hard to make sure there are no others viruses present in vaccines

But, that said, there are also auto-vaccinations which remind the dendritic cells (correct me please if I'm wrong at any time, I'm here to learn as well) to attack the virus/bacteria/fungi.

Also please read about the benefits and what naturally occurs when children are not vaccinated:

Neil Miller:

When children contract chickenpox, when children contract measles, mumps, rubella, you gainprotective benefits that protect you in later life against cancer. Several studies, multiple studieshave confirmed this time and again. These are really vaccinated against unvaccinated studies.These are studies where they’ve compared populations that had caught these diseases naturally versus populations that never got these diseases. They look at the cancer rates in later life.

JM: Let me stop you there because I think it’s an important point. I don’t know that anyone inthese studies have ventured to guess or speculate on the mechanism. But it would seem to me that when you have a naturally acquired infection, you’re really exercising your immune system quite profoundly in developing authentic immunity, lifelong immunity, which is radically different from the type of artificial immunizations that are done through vaccinations, which is not life long – it rarely ever is – and has relatively decreasing antibodies and actually stimulates a different part of the immune system.

It could potentially increase your risk of cancer rather than decrease it. We see that in many ofthese other vaccines, like human papillomavirus (HPV) vaccine.

NM: When you are vaccinated, you are prevented from gaining that lifelong natural protectionagainst cancer. Also, I’ll mention against heart disease.

JM: What’s the mechanism there?

NM: I’ll tell you about several other studies that confirm that the infections – They know that later born children – they’ve known this for years and several studies show this – I don’t show these studies in my book but I mention it in the introduction to the chapter on cancer and natural infections. Several studies have confirmed time and again that later born children are actually more protected against cancer than firstborn children. And again, for the same reason. They are exposed to more infections.
