Effectiveness of mRNA, protein subunit vaccine and viral vectors vaccines against SARS-CoV-2 in people over 18 years old: a systematic review.

Introduction: Vaccines prevent disease and disability; save lives and represent a good assessment of health interventions. Several systematic reviews on the efficacy and effectiveness of COVID-19 vaccines have been published, but the immunogenicity and safety of these vaccines should also be addressed.

Areas Covered: This systemic investigation sought to explain the efficacy, immunogenicity, and safety of new vaccination technologies against SARS-CoV-2 in people over 18 years old.

Identification of Nontuberculous Mycobacteria in Drinking Water in Cali, Colombia.

Nontuberculous mycobacteria (NTM) are ubiquitous microorganisms naturally resistant to antibiotics and disinfectants that can colonize drinking water supply systems. Information regarding the spread of NTM in specifically South America and Colombia is limited. We aimed to identify and characterize NTM present in tap water samples from Cali, Colombia.

Molecular Characterization of KPC-2-Producing Complex Isolates from Cali, Colombia.

The complex is an emerging opportunistic pathogen whose increased resistance to carbapenems is considered a public health problem. This is due to the loss of efficacy of beta-lactam antibiotics, which are used as the first treatment option in the management of infections caused by Gram-negative bacteria. The objective of this study was to perform the molecular characterization of 28 isolates of the complex resistant to cephalosporins and carbapenems isolated between 2011 and 2018 from five hospitals located in the municipality of Santiago de Cali, Colombia.
