Every disease is different. Every vaccine is different. Every child is different. Every family situation is different. You will have to weigh all of these factors yourself and do your own research. It's difficult because there is very little good solid science on either side of this debate. Almost all the the studies are severely biased, too short, too small, or asking the wrong questions. Good science in this area tends to be politically infeasible, astronomically expensive, unethical, or impractical.
So we pretty much have to take the data we have, make the best guesses we can, and live with the consequences.
When doing your own research, always take into account the bias of the source. Counter-bias information is most likely to be valid. If you see anti-vaccine information from a pro-vaccine source (like the CDC), it's probably valid. If you see pro-vaccine information from an anti-vaccine source, it's probably valid.
I always recommend starting with vaccine inserts (which are available on the web) and the doctor's side of the CDC website. These are strongly pro-vaccine sources. If you find anything that worries you, it's likely to be valid.
Most pro-vaccine information that is aimed directly at parents is so oversimplified as to be propaganda. Read the stuff aimed at doctors. It is much more nuanced.
It is good to understand something about how vaccines are licensed.
Step 1: Research, development, etc.
Step 2: FDA approves the vaccine as "effective and safe" This is the exact same approval process that all other drugs go through. As we have seen with other drugs, the FDA has been known to be wrong. However, CDC and doctors will assume that *any* vaccine licensed by the FDA is "effective and safe" and proceed accordingly. As far as I know, there is no established definition of "effective". Some vaccines are over 90% effective. Some vaccines are less than 70% effective. But they are all classified the same way by the FDA.
Step 3: The CDC makes a recommendation for use. If they put it on the vaccine schedule, manufacturers will make it, insurers will cover it, doctors will offer it, and parents can choose it. If they don't, the vaccine may not be available for anyone. For this reason, the CDC is under incredible pressure to put as many vaccines on the schedule as early as possible. It is the earliest possible schedule that lines up with existing well-baby checks. To repeat, the CDC schedule is driven by a lot of non-medical considerations.
In your research. keep in mind that correlation does not mean causation. People with white hair tend to have fewer years left to live than people with brown hair. This does not mean hair dye will extend your life. Hair color and life expectancy are both correlated with a third factor, which is age.
I am convinced that vaccines do not cause autism. However, I have observed that a hugely disproportionate number of autistic children have a history of vaccine injury. I personally suspect that whatever factor causes autism also leaves children much more vulnerable to vaccine injury. I also suspect that whatever factor is driving up autoimmune disorders is also driving up negative vaccine reactions. As far as I know, no one has researched this.
Finally, research the diseases themselves, their treatment, and appropriate quarantine. Remember that many people are immuno-compromised, and the increasing use of steroid medication makes this number even higher. Whether you vaccinate or not, practice quarantine when you are ill.
Please make sure you understand a disease even if you decide to vaccinate!!!!! Sometimes vaccines fail. One of my major beefs with the pro-vaccine crowd is vaccinated people walking around in the community with an obvious and very contagious case of pertussis. The pertussis vaccine has a high failure rate and wears off quickly. The vaccine reduces the risk significantly, but for the purposes of public health everyone should assume they are not immune and behave accordingly. If you have a cough of any type, stay away from newborns!!!! And if your newborn has a cough of any type, get them tested for pertussis.
Hope this helps. Feel free to contact me privately if you want my data on specific vaccines.
What are we doing? We're doing an alternate vaccine schedule, with vaccines spaced out. My son has been hospitalized twice for asthma and has various sensory problems, my daughter is pretty healthy. My son had one problematic vaccine reaction, my daughter has had no problems. Since we did delayed and spaced-out vaccination, I can say without hesitation that my son's health problems were *not* caused by vaccination. They existed before he got his first vaccine.
