Good: + ~94.5% of individuals achieve immunity. Better than Pfizer, though we need more data to be sure. + no significant side-effects. + no special deep freezing. -20C is good for 6 month storage, -2 to -9 for 30 days comparing to Pfizer -70C all the time. Not so good: - two doses needed, 4 weeks apart, immunity after one and a half month from first dose. Slow rollout. Pfizer results were after one month. Still long-term immunity is a question for every vaccine. Luckily, if two vaccines works then likely other attempts will be successful.
