Radiologic findings according to the vaccination status.
| Chest X-ray | NV (n = 378) | FV (n = 45) | PV (n = 13) | BV (n = 30) | P value |
|---|---|---|---|---|---|
| Consolidation | 287(%75.9) | 26 (%57.8) | 5 (%38.5) | 14 (%46.7) | <0.001‡ |
| Interstitial/patchy | 135(%35.7) | 28 (%62.2) | 11(%84.6) | 21(%70) | <0.001† |
| Cavitation | 18 (%4.8) | 2 (%4.4) | 1 (%7.7) | 0 (%0) | 0.536 |
| Multilobar involvement | 67(%17.7) | 11(%24.4) | 4(%30.8) | 7(%23.3) | 0.425 |
| Pleural effusion | 71(%18.8) | 4(%9.1) | 0 (%0) | 5(%16.7) | 0.143 |
‡
The patients who had received neither vaccine (NV) were significantly more likely to present with consolidation on chest X-ray than the patients who had received both vaccines (BV) or the just pneumococcal vaccine (PV).
†
The patients who had received neither vaccine (NV) had a lower frequency of interstitial/patchy infiltrates on chest X-ray than the patients who had received either or both vaccines.
