Your use of "efficiency" is the same as my use of "effectiveness" in the context of my previous post.

It is still not the same thing as antibody production, i.e. efficacy.

Can you explain more about this normal immune response?

have just stated is our current understanding of host-pathogen relationship and is based on germ theory. I would also add that whether someone gets the disease or not also depends on the virulence of the microorganism and dosage in addition to the state of their host defenses. A very virulent organism will cause disease in someone who was previously healthy with a fully intact, functional immune system. Exposure to an overwhelming number of organisms can also overwhelm a fully intact, functional immune system as well.
What I stated had nothing to do with Germ Theory. It was actually based on Cellular Theory which is the complete opposite of Germ Theory.

A person’s nutritional status could change the virulence of a virus. Immune suppression happens when there are nutritional deficiencies of essential nutrients, which allows viruses to become more virulent. Russell Blaylock M.D.’s book “Health and Nutrition Secrets That Can Save Your Life” documents this in studies on page 163 of that book. One particular study demonstrated that the “coxsackievirus” caused a particular form of heart damage in certain regions of China, but it was discovered the disease only occurred in areas with low soil selenium levels. Therefore, if the virus was imported into the U.S. from China, the focus should be not on how virulent the virus can potentially become, but to make sure that we have optimal nutritional levels, particularly in selenium, to prevent the virus from becoming highly virulent in the first place.

The anti-body theory that you are referring to in the above quote concerns only the humoral (Th2) branch of the immune system, the branch that is responsible for antibody production and ignores the cellular (Th1) branch of the immune system, the branch that is responsible for digesting and discharging microorganisms. Vaccines overstimulate the Th2 branch, and do not stimulate the Th1 branch, thus causing an abnormal immune respose, which causes “the functional balance of the immune system toward the antibody-producing side (Th2) and away from the acute inflammatory discharging side (the cell-mediated side or Th1).”

The quoted part is from:

Scroll down to the "It’s not so complicated" section of the article for more of an explanation on immune system function and response.

As for vaccinated individuals passing on the wild strain...not likely since their immune system prevents the virus from replicating. Without replicating, there is nothing to pass on.
Can you please explain how vaccines force a person’s immune system to prevent viruses from replicating? I’ve never heard anyone say that vaccines have that ability, so I’m interested to know where you got that theory from?

I have tons on this, but here is the first one that comes up on a search through my material here, concerning DTaP ( I know, bacteria here, but it's kinda the same idea)

Therefore, it is tempting to speculate that vaccine-induced immunity prevents extensive multiplication of the bacteria on the mucosal surfaces after infection (reflected by a moderately or weakly positive PCR). In support of this hypothesis, it has recently been shown experimentally by a quantitative PCR method that the total number of detectable B pertussis genomes correlated well with the number of viable bacteria detected by culture.27

I have more for MMR, rotavirus and OPV- which fit the bill more since they are viruses. I'll pull them up asap.

Thanks, but it doesn't answer my question about "how" vaccines force a virus to stop replicating. Exactly how does the vaccine manipulate a person's immune system to do this? I'm still confused because considering that the cellular (Th1) branch of the immune system's job is to find and destroy the virus, a healthy immune system already does this on its own without vaccines; and also considering that vaccines do not stimulate the Th1 branch.
