What are the main risks or harms, and how common are they by vaccine?

The evidence block is empty. No studies were retrieved for this question, so there is nothing to ground an answer in. The specific sub-question that would be answerable is: for each named vaccine, what are the reported rates of specific adverse events in the retrieved records, and how do those rates compare across vaccines?
