Except the bottom line is that none of those are valid reasons.
Baring genuine medical reasons, childhood vaccines should be compulsory for everyone. You are living as part of a society, your rights effectively end with the next person. One persons choice not to vaccinate, directly puts another at risk.
Minx is of course ignorant and misinformed. The dose matters. You are exposed to all those things in the environment "naturally" anyway. Not to mention the fact Thimerosal was removed from the required childhood vaccines a decade ago. Nothing is injected into your veins.
Edit: This time, at least Lighty is asking about what he doesn't understand rather than the other quacks who clearly don't know what they are talking about, but assume they do..
"What I don't understand is why heard immunity is necessary for the vaccine to be effective."
If everyone is vaccinated, it's much harder for the disease to pass between people who are not. Not just those who choose not to vaccinate, but those who don't respond to vaccines (remember no vaccine is 100% effective), and those who cannot have vaccines for various medical reasons. If enough people are immune, it confers universal protection since the disease cannot survive in the community.
"Also why are boosters necessary? "
Because immunity to everything will wane over time. Even with the natural infection. Some natural infections may provide longer immunity than the vaccine, however you would have to risk the wild infection to get that. In the case of the measles vaccine, most people don't require a booster in adult life.
In the case of the HPV vaccine, it actually produces longer lasting immunity than the natural infection.
It also depends on the disease, the person and the vaccine. Hope that clears it up.
Those, like thenoseknows, who claim, "herd immunity is now passe" don't understand epidemiology and infectious diseases. Where vaccination rates drop, the diseases return. Look whats happening here in the UK right now with measles.
There are numerous examples of this trend.
Edit: Lighty: I have to ask, are you deliberately trying to make yourself look dumb? It's working very well.
"Why are you concerned about those of us who choose not to be vaccinated? "
Again (and this really is the last time, if you don't get it now, you're never going to get it), it's not to protect those who choose not to be vaccinated, it also protects those who are vaccinated and don't respond to it, and those who cannot have vaccines for various medical reasons (e.g. those with allergies to certain components of the vaccine or those who have weakened immune systems, through various diseases or drugs, and don't mount a response to it.) These are the people in society who need protecting.
"Where is the evidence that immunity wanes overtime? "
How about basic physiology for starters? The immune cells to a disease will die if they are not stimulated again.
"And how would you know this? The vaccine hasn't been around for very long. I'd like to see this evidence too please."
HPV vaccine provides immunity for at least 5 years, realistically, it will probably provide immunity for much longer: http://www.ncbi.nlm.nih.gov/pubmed/16631880?dopt=Abstract
HPV evades detection by the immune system, so the antibodies produced from the natural infection are not reliable to protect against a subsequent infections. HPV infects through micro-abrasians, and does not enter the blood stream.
The vaccine induces high levels of neutralizing antibodies in the blood.
