Abstract:
This study examined COVID-19 Reporting and Data System (CO-RADS) scores, reverse transcription polymerase chain reaction (RT-PCR) positivity, and COVID-19 vaccination status of COVID-19 patients who reported to the emergency room (ER). Thus, it aimed to present how much effective the vaccines were.
Methodology: It was a cross-sectional, retrospective, descriptive research, covering the period between June 08, 2021 to August 08, 2021. The study was conducted at Sakarya University Teaching & Research Hospital, Sakarya. Institutional ethical review committee certificate was not required as it was a retrospective study.
Results: One hundred four cases were included in the study, of which 61 (58.7%) were male, and 43 (41.3%) were female. Of the patients, 35 (33.6%) had no COVID-19 vaccination, 46 (44.2%) had two-doses CoronaVac, one (1%) had two-doses BNT162b2. Out of 104 patients, 12 had a CO-RADS-3 score, 17 had a CO-RADS-4 score, and 60 patients had a CO-RADS-5 score. No significant difference was recognized between unvaccinated cases and vaccinated patients with two CoronaVac doses in terms of hospitalization, RT-PCR positivity and mortality (respectively: x2 = 0.176, SD = 1, p = 0.675; x2 = 0.025, SD = 1 , p = 0.874; x2 = 0.830, SD = 1, p = 0.362). Two doses CoronaVac vaccinated patients' length of stay in the hospital was determined to be more succinct than cases who had never been inoculated (U = 596.500, p = 0.045, z = 2.003, r = -0.22).
Conclusion: Prolonged time after CoronaVac vaccination may reduce the vaccine's protection against COVID-19 pneumonia. The protection of two doses of BNT162b2 against COVID-19 pneumonia presents promise in the fight against the pandemic. Those inoculated with at least two doses of CoronaVac or BNT162b2 had a shorter hospital stay than those not vaccinated. RT-PCR positivity may continue to be observed in vaccinated patients.
