Abstract
Background
The impact of vaccination prior to infection on postacute sequelae of coronavirus disease 2019 (COVID-19, PASC), also known as long COVID, remains unclear. Here we assess the protective effect of vaccination on long COVID in a community-based setting.

Methods
The Immunity Associated with SARS-CoV-2 (IASO) study is an ongoing prospective cohort of working adults that began in October 2020. Participants are actively followed for severe acute respiratory syndrome coronavirus 2 infection. We compared the prevalence of symptoms and symptom severity in vaccinated compared to unvaccinated cases. Our primary definition of long COVID was the presence of symptoms at 90 days postinfection; 30 days postinfection was also examined.

Results
Overall, by 90 days postinfection, 13% of cases had long COVID, with 27% of unvaccinated cases and 8% of vaccinated cases reporting long COVID (relative risk [RR], 0.31 [95% confidence interval {CI}, .22–.42]). Vaccination was also associated with significantly lower average severity scores at all timepoints (eg, relative severity at 90 days postinfection: −2.70 [95% CI, −1.68 to −3.73]). In the pre-Omicron era, 28% of unvaccinated cases and 18% of vaccinated cases reported long COVID (P = .07), and vaccinated cases reported less severe symptoms including less difficulty breathing (P = .01; 90-day RR, 0.07).

Conclusions
Vaccinated cases had lower prevalence of long COVID and reduced symptom severity

Vaccinated Compared to Unvaccinated Cases
By 90 days postinfection, 8% of vaccinated cases were still reporting any symptoms, compared to 27% of unvaccinated cases. Any symptoms were 37% and 69% less common for vaccinated cases at 30 and 90 days postinfection (RR, 0.63 [95% confidence interval {CI}, .52–.76] and 0.31 [95% CI, .22–.42]), respectively.
Similarly, having 5 or more symptoms was 63% and 66% less common for vaccinated cases at 30 and 90 days postinfection (RR, 0.37 [95% CI, .24–.58] and 0.34 [95% CI, .15–.79]), respectively.

特定の症状を調べたところ、ワクチン接種症例ではより急性の上気道症状がみられました（喉の痛み：RR、1.72 [95% CI、1.42-2.09]、鼻づまり：RR、1.50、[95% CI、1.27-1.77]、咳： RR、1.44 [95% CI、1.22-1.71])、それでも急性上気道症状はそれほど重篤ではありませんでした。ワクチン接種を受けた症例は重症度が低く、急性およびPASC下気道症状はそれほど多くありませんでした。
急性期および感染後 30 日および 90 日では、ワクチン接種症例では呼吸困難が 46%、58%、75% 低かった (RR、0.54 [95% CI、.42-.70]; 0.28 [95% CI、.それぞれ、18 ～ .44]、0.25 [95% CI、.12 ～ .55])
筋肉や体の痛み、疲労、悪寒、睡眠障害、嗅覚・味覚の喪失、頭痛、消化管の問題、認知機能障害など、他の症状も感染後30日および90日ではワクチン接種例ではあまり一般的ではありませんでした。さらに注目すべきことに、症状の重症度は急性期および感染後30日で一貫して低かった

興味深いことに、個々の症状の重症度の軌跡は、ワクチン接種済みの場合とワクチン接種を受けていない場合で異なりました。ワクチン接種を受けた症例では、多くの症状（咳、倦怠感、呼吸困難など）の重症度が平均して明らかに低下しましたが、ワクチン接種を受けていない多くの症例では、時間が経っても同じ重症度レベルが維持されていました。
