Keep yer fingers crossed on the new variants that might pop up, I suspect this might be true for all the approved vaccines, certainly Moderna's mRNA vaccine.
This is prevention folks and that is important for getting back to normal, it will mean 90% of vaccinated people won't get it or spread it and will act as a barrier between those who do and the vulnerable, it means vaccines will stop this thing and it's current crop of known variants. Even those vaccinated who end up with a case (9%), it's a milder illness and likely non fatal.

Pfizer/BioNTech COVID-19 shot 91% effective in updated data, protective against South African variant
(Reuters) - Pfizer Inc and BioNTech said on Thursday their vaccine is around 91% effective at preventing COVID-19, citing updated trial data that included participants inoculated for up to six months.
The shot also showed early signs of preventing disease in a small subset of study volunteers in South Africa, where a concerning new variant called B.1.351 is circulating.
Although lower than the stunning 95% efficacy result reported from its 44,000-person clinical trial in November, overall efficacy of 91.3% shows the vaccine to be a powerful tool against an evolving virus. The virus now has more transmissible forms and those that have been shown to evade antibody protection in lab studies and real-world clinical trials.
“These data reinforce our view that we have some really potent vaccines,” said Danny Altmann, a professor of immunology at Britain’s Imperial College London, who was not involved in the Pfizer trial.
