I think our total body of information on vaccine effects is too limited for any of us to be more than partially informed, unfortunately. Thus everyone's decision is based on some combination of accurate information and guessing or intuition. Everybody has some basic biases about human health and government and the pharmaceutical industry that influence them from the outset.
Individual research has its limitations. I think it is important to learn what you can, but obviously people draw different conclusions from the information we have and have different levels of trust in certain sources. People have different levels of interest in and ability to analyze the available information as well.
I completely agree.
