The Long-Term Serological Profile of CoronaVac Vaccine Based on Comorbidities and History of SARS-CoV-2 Infection in Indonesia.

CoronaVac is one of the most widely administered COVID-19 vaccines in Indonesia. Previous studies have documented its effectiveness in protecting against COVID-19 in several countries. This study aimed to assess the long-term immunogenicity of CoronaVac in individuals with comorbidities or a history of SARS-CoV-2 infection.

Diagnostic Methods of Common Intestinal Protozoa: Current and Future Immunological and Molecular Methods.

Intestinal protozoan infection is a persisting public health problem affecting the populations of developing countries in the tropical and subtropical regions. The diagnosis of intestinal protozoa remains a challenge especially in developing countries due to a shortage of laboratory facilities, limited health funding, and the remoteness of communities. Despite still being widely used, conventional diagnoses using microscopy and staining methods pose important limitations, particularly due to their low sensitivities and specificities.

The Role of Vitamin D for Modulating the T Helper 1 Immune Response After the Coronavac Vaccination.

The purpose of this study was to observe the role of vitamin D levels with T helper 1 (Th1)-type cytokines, such as interferon γ (IFN-γ) and interleukin-12 (IL-12) efficacy, in those who had already received 2 injections of inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) vaccines (CoronaVac). We also observed if these cytokines played any significance in the CoronaVac effectiveness for preventing coronavirus disease 2019 (Covid-19) infection. One hundred ninety-four volunteers were monitored for 8 months upon receiving 2 inactivated SARS-CoV2 vaccination injections (CoronaVac, Sinovac Life Sciences).
