Abstract

The waning immunity following the COVID-19 vaccination become a significant concern and the immunological dynamics of vaccine-induced antibodies after vaccination need to be explored. The aim of this study was to compare anti-SARS-CoV-2 receptor-binding domain (RBD) antibody levels before and after a booster dose with heterologous COVID-19 vaccine and to identify factors influencing the levels after receiving the booster dose. A cross-sectional study was conducted in which individuals who received primary doses of CoronaVac and a booster dose with an mRNA-based vaccine were recruited using a purposive sampling technique. The titers of anti-SARS-CoV-2 RBD antibodies were measured using an enzyme-linked immunosorbent assay (ELISA), and plausible associated factors were collected using a questionnaire-assisted face-to-face interview. The Wilcoxon test was used to compare the titers before and after the booster dose, while the Kruskal-Wallis and Mann-Whitney tests, followed by multivariate linear regression, were used to assess the factors associated with RBD total antibody titers. The results showed that there was a significant increase of anti-SARS-CoV-2 RBD total antibody titers before and after receiving the booster dose (1,558.7 BAU/mL vs 140.6 BAU/mL, p<0.001). The analysis revealed that age (p=0.555), sex (p=0.254), type of vaccine (p=0.914), presence of hypertension (p=0.541), diabetes (p=0.975), chronic obstructive pulmonary disease (COPD, p=0.620), and gout (p=0.364) were not associated with anti-SARS-CoV-2 RBD total antibody titers. However, the titers of anti-SARS-CoV-2 RBD total antibody were significantly different between those with and without hyperlipidemia (p=0.021). This study suggests that a booster dose with a heterologous COVID-19 vaccine could significantly enhance immune responses against COVID-19, and therefore, this strategy may be recommended as part of preventive measures to strengthen immunity against COVID-19.

Abstract

The coronavirus disease 2019 (COVID-19) vaccination program in Indonesia has been implemented as a key strategy to mitigate the spread of the virus within communities. The success of this program depends on public acceptance of COVID-19 vaccines, including booster doses. The aim of this study was to assess the acceptance of the COVID-19 booster dose in Indonesia and to identify factors influencing individuals' acceptance. A cross-sectional study was conducted across 34 provinces in Indonesia on June 2023. Logistic regression analysis was used to identify the factors associated with booster dose uptake. The findings revealed that 88.8% (2,049/2,308) of respondents were willing to receive a booster dose if provided free of charge by the Indonesian government. However, acceptance decreased to 61.7% when respondents were informed of a 20% likelihood of side effects, even with a reported 95% vaccine efficacy. Adjusted logistic regression analysis identified ten significant factors associated with booster dose acceptance: sex, age, religion, history of previous COVID-19 infection, type of primary vaccine received, belief in vaccine-related conspiracy theories, trust in traditional medicine conspiracies, confidence in natural immunity, perceived vaccine efficacy, and perceived vaccine effectiveness. These findings suggest that acceptance of COVID-19 booster doses in Indonesia is influenced by intrinsic and extrinsic factors, including limited knowledge of booster dose benefits and concerns about potential side effects. To enhance public acceptance, targeted health campaigns and educational initiatives should be intensified, emphasizing the safety, efficacy, and importance of booster vaccinations in controlling the COVID-19 pandemic.
