Indonesia began deploying a COVID-19 vaccine in January 2021, prioritising vaccination for high-risk groups such as healthcare workers, the elderly and those with comorbidities, and ending with the general public due to limited vaccine availability. Our study aimed to evaluate antibody response in Indonesians who had received two doses of the vaccine vs. those who had not. The study design was a cohort study involving 46 unvaccinated people and 23 people who had received the second dose of the AstraZeneca vaccine in three months. Methods used for the qualitative and quantitative detection of IgG antibodies included rapid RI-GHA and ELISA tests. Findings showed that positive IgG antibodies qualitatively detected by the rapid RI-GHA test were significantly higher in those vaccinated (60.9%) than in unvaccinated people (26.1%). Using the ELISA assay, all vaccinated individuals qualitatively showed positive antibodies (cut-off ≥4.33 BAU/ml), and the average quantitative titer of anti-SARS-CoV-2 s-RBD IgG was significantly higher in vaccinated (157.06±238.68 BAU/ml) than in unvaccinated (51.90±87.60 BAU/ml) individuals. Some unvaccinated individuals with no history of infection were found to have anti-SARS-CoV-2 antibodies that may have been previously asymptomatic, although their mean antibody titers were certainly lower than those in the 2-dose group. Approximately 56% of vaccinated individuals had antibody titers above 60 BAU/ml as a cut-off for protective threshold, a significantly higher proportion than unvaccinated individuals. In conclusion, vaccination with two doses AstraZeneca increased anti-SARS-CoV-2 antibodies which resulted in enhanced immunity against symptomatic COVID-19. [ABSTRACT FROM AUTHOR]

During the coronavirus disease 2019 (COVID-19) pandemic, some countries, including Indonesia, have faced a double burden with regards to disease control. As Indonesia is a tropical country, it serves as a suitable host for disease vectors and multiple microorganisms of causative agents of disease. In total, five of the neglected tropical diseases (NTDs) should be a consideration in Indonesia during the COVID-19 pandemic, including leprosy, yaws, filariasis, soil-transmitted helminths and schistosomiasis. The present review summarises the preparedness of Indonesia in facing NTDs during the COVID-19 pandemic. Strengthening government leadership will be a valuable factor for combating NTDs in Indonesia. For instance, strong leadership can lead to precise management, by increasing the number of health facilities, engaging in active case identification, conducting health campaigns and instituting new regulations to prevent the stigmatization faced by patients. Preventive medicine in the first level of health facilities can be prioritized and presented to the community via health campaigns, health advocacy and improvement in follow-up after active case surveillance. Government-supported integrated management is also a key component in eliminating NTD. Moreover, healthy lifestyle campaigns that include social distancing, wearing a mask and regularly washing hands should be promoted continuously to reduce the transmission of COVID-19, which is potentially associated with a poor outcome in individuals with NTDs. This review concluded that the Indonesian government should strengthen their efforts toward NTD control using alternative methods, such as involving key citizens in the collaboration of the detection of new cases and introducing mobile health as a means of detecting health problems or following up on patient progress. To reduce the transmission of COVID-19, testing, tracing and treatment must be improved, so that the gap between suspected cases and confirmed cases of COVID-19 can be closed. If the transmission of COVID-19 can be decreased, case detection and efforts toward NTD control can be conducted effectively. [ABSTRACT FROM AUTHOR]
