Abstract
Background
The duration of immunological persistence in COVID-19-vaccinated individuals is considered a matter of concern. Some studies have shown that anti-SARS-CoV-2 antibodies degrade rapidly. Due to diminishing immunity after vaccination, some people may catch an infection again after receiving the COVID-19 vaccine.
Objectives
The purpose of the present study was to measure the COVID-19 post-vaccination infection reported by the vaccinated participants and to identify possible associated risk factors among hospital attendants in Qena city.
Material and method
A cross-sectional study was carried out on 285 participants who received COVID-19 vaccines and were aged 18 years or more. A structured questionnaire was used as a tool for data collection.
Results
13.7% of the vaccinated participants reported catching the COVID-19 infection after vaccination. Healthcare workers were more susceptible to the COVID-19 infection after vaccination than non-healthcare workers. Post-vaccination infection among participants who received Viral vector vaccines, Inactivated vaccines, and mRNA vaccines were 16.7%, 15.7%, and 3.6%, respectively.
Conclusion
Healthcare professionals need to take strict preventive measures since, even after receiving the COVID-19 vaccine, they are more vulnerable to infection than non-healthcare personnel. mRNA vaccines can be given in place of viral vector vaccinations because they show a reduced incidence of post-vaccination infection.
