All vaccinated &amp; non vaccinated&nbsp; persons &nbsp;(18 years of age and above) who had &nbsp;symptoms suggestive of COVID-19 were engaged &nbsp;in &nbsp;the study . Nasopharyngeal swabs were collected &nbsp;&nbsp;and examined for SARS-CoV-2 by real-time RT-PCR implemented &nbsp;to all attendance&nbsp; according to World Health Organization guidelines.</p><p><strong>Results:</strong> A total of 2934 persons&nbsp; had attended&nbsp;&nbsp; the Central Laboratory for checking&nbsp; during the study period. From&nbsp; this total number,551 (18.8% ) were vaccinated while 2383&nbsp; were nonvaccinated (81.2%). Sixty one persons (61, 11.1%) of the vaccinated group showed&nbsp; a positive PCR . The highest incidence&nbsp; of PCR&nbsp;&nbsp; positivity according to age&nbsp; range , gender&nbsp; and vaccine &nbsp;dose , were as follows: male (42; 68.9%), 33–47 years (36; 59%), second dose&nbsp; (36; 59%) respec­tively. Statistically, the dif­ferences of distribution of the PCR positivity concerning the these&nbsp; factors&nbsp; were : non-significant . The higher incidence of PCR positivity&nbsp; was among the nonvaccinated group ( 449,18.8% ) and statistically, the differences of distribution of the PCR&nbsp; positivity between both groups of vaccinated and the nonvaccinated&nbsp; was significant (<em>p </em>≤ 0.05).</p><p><strong>Conclusions:</strong> Primarily the present study conclude that SARS-CoV-2 incidence among vaccinated persons was 11.1%. Overall the present &nbsp;data provides further assurances of the effectiveness of the vaccines even when the vaccine was not able to prevent &nbsp;completely&nbsp; the infection . Further studies are needed to explore this topic.</p> ER -
