Evaluation of SARS-Cov-2 neutralizing antibody among Sinopharm Vero Cell (BBIBP-CorV) vaccinated medical students.
Background: Information regarding seropositivity and vaccine efficacy among medical students is scarce. This study aims to detect the status of SARS-CoV-2 neutralizing antibodies among the Sinopharm's Vero Cell (BBIBP-CorV) vaccinated medical students.
Materials and methods: A prospective, cross-sectional study was carried out among medical students of Gandaki Medical College Teaching Hospital, Pokhara, Nepal from March through August 2022. The level of SARS-CoV-2 serum- neutralizing IgG antibody was measured and its relation with participants' age and sex, duration of vaccination, and any comorbid condition was determined.
Results: A total of 110 medical students were included in the final analysis, the majority being females (65.5%) and the mean age is 23.1 ± 3.2 years. Most of the students (96.4%) had neutralizing antibodies against SARS-CoV-2. Among the 29 (26.36%) students who received a booster dose, the positivity rate was 100%. The mean IgG levels were 9.57 ± 9.58 μg/ml and 2.91 ± 2.47 μg/ml among students receiving an additional booster dose and among those not receiving it, respectively. In the cohort receiving a booster dose of the vaccine, the average value of neutralizing IgG antibodies was high. In contrast, the ones not receiving it, the titers were low and showed a declining trend.
Conclusion: Though the dose strategy of the Sinopharm vaccine is effective, booster vaccination may be an important strategy to ensure protection among medical students, who are at high risk of COVID-19 due to constant patient exposure during their training. Further studies should assess vaccine efficacy among individuals who received other vaccines as well.
期刊介绍：
Human Antibodies is an international journal designed to bring together all aspects of human hybridomas and antibody technology under a single, cohesive theme. This includes fundamental research, applied science and clinical applications. Emphasis in the published articles is on antisera, monoclonal antibodies, fusion partners, EBV transformation, transfections, in vitro immunization, defined antigens, tissue reactivity, scale-up production, chimeric antibodies, autoimmunity, natural antibodies/immune response, anti-idiotypes, and hybridomas secreting interesting growth factors. Immunoregulatory molecules, including T cell hybridomas, will also be featured.
