There's nothing particularly special about this vaccine (EDIT: okay, the mRNA is a little special), and we data information about long-term negative effects of past vaccines ([0] has positive events, plus several false positives[0]). Overall, sure looks like the risk is substantially lower than the risk of COVID-19 is, including for a young, healthy person.
