I don’t have time to address all of the responses, but where you’ve come closer than anybody else to addressing my questions, I’ll take some time with yours.
I would argue that it’s impossible to make an omelet (herd immunity) without breaking a few eggs (children). This cliche, (attributed to Lenin, I believe), is the defining crux of utiltarianism.
Wouldn’t it also be unethical to not immunize your child, and possibly get your child sick because he/ she is unprotected, and also place other children at risk?
If vaccines were 100% safe and 100% effective, then my answers would be yes. Where the issue isn’t so black and white, however, I would say that it would not necessarily be unethical.
Is it ethical for parents to refuse to seek medical treatment for their child, because they are afraid of the side effects of drugs?
Under all but the most clear-cut circumstances, yes. With all medical interventions, there are risks to accepting and risks to refusing. It must necessarily rest with parents, (or the individual patient, if an adult), to decide which set of risks they are willing to take on, rather than allowing any governing body to make that choice for them.
I chose to accept the risks that come with vaccines and vaccinate my children.
If one of my children suffered a severe vaccine reaction, the mere possibility that it was caused by the vaccine would give me pause and compel me to stop vaccinating. In medical ethics, this is called the Precautionary Principle.
Or afraid that their child may catch something more serious for the hospital? Children have died because their parents misunderstood the risks of medicine. Children have also died because their parents refused to vaccinate them. And this risk is far greater than the risk of vaccine side effects.
Children have died because their physicians have misdiagnosed them, misunderstood medicine, or been flat-out negligent. Indeed, I’ve seen figures ranging from 90,000 to 400,000 Americans dying annually of medical negligence. That’s a few more than measles, (albeit without a fraction of the moral outrage directed toward measles outbreaks), wouldn’t you say? Some modicum of medical choice helps counter-act this effect.
I understand and respect where you’re coming from. I’ve been name-called an “anti-vaxxer,” which is mildly amusing because I’m wondering how I can be anti-something-I’m-already-doing. What I’m trying hard to convey is that this issue is not a black and white one.
