This is such a hard issue to navigate. I know last year they were out out out of vaccines in my area and then when the hype was over there was a surplus and they did what seemed like a marketing campaign to get people in and buy the surplus. I don't care to make pharmaceutical companies wealthier by allowing injections into my precious body, much less that of my children. Frankly, I pay a lot of attention to advertisement and I think pharm companies are doing a lot of harm (and a lot of good, but profit is always the motivation).
I've lived in the third world and had drugs banned on the US pushed on me, PUSHED on me by my neurologist who was under a grant from the pharma company who sold the drug (while they were in litigation over the drug for marketing it as a pain reliever, eplipsy drug, ADHD drug, Bi-Polar drug, etc. They said it was the "cure all." forget that I thought I had epilepsy and I was nursing and they could guarantee that it wouldn't get in my milk.) This doctor literally tried to force me to take the drug in his office when I refused. When you can't sell in the US, go where poor people can't sue you is how these monsters work.
So I don't trust the drug companies. Not one bit.
But, living there I also saw the crippling effects of not vaccinating segments of the population, and it's not pretty.
In my case, when my kids were at home I did not do the flu shot. We did do lots of handwashing. I've had my daughter build an incubator and culture bacteria so that she understands how important hand washing is. My children are extremely thin -- off the charts -- and I do worry if they get very ill with something that causes nausea and vomiting so now that they are in school, I probably will.
