I'm not sure it's fully possible to not compromise on safety one way or another when doing something like this quickly. Let's say a side effect is that 1% of women become sterile half a year after getting the vaccine - how would we possibly know that after testing for 3 months? All we can do is say it's very unlikely based on other vaccines with similar approaches, and monitor for effects on the reproductive system (or anything else unusual in the body) that is know to potentially lead to something like that down the line. In the end, we can (and probably must) decide that taking the time to disprove there being any long term negative effects, is more likely to cause more harm (because more covid-infections will happen in the meantime) than the good it is likely to do us. But it is still a higher risk than the usual approach where we test for longer.
