En octubre 31 del 2021, Colombia inició la vacunación contra COVID-19 para niños de 3 a 11 años de edad, con la vacuna CoronaVac (Sinovac). Esta estrategia se implementó en ausencia de un informe técnico sobre la eficacia y seguridad de CoronaVac en niños, y sin una evaluación del costo-beneficio de esta, en comparación con otras estrategias. En este comentario se consideran aspectos fundamentales que debieron tomarse en cuenta al ponderar si los beneficios de esta estrategia eran mayores que sus riesgos. Específicamente, la eficacia y seguridad de CoronaVac en niños de 3 a 11 años, la relación riesgo/beneficio de la estrategia, el rol de los niños en la transmisión comunitaria de SARS-CoV-2, y las implicaciones éticas de la estrategia.

Saliva samples may be an easier, faster, safer, and cost-saving alternative to NPS samples, and can be self-collected by the patient. Whether SARS-CoV-2 RT-qPCR in saliva is more accurate than in nasopharyngeal swaps (NPS) is uncertain. We evaluated the accuracy of the RT-qPCR in both types of samples, assuming both approaches were imperfect. We assessed the limit of detection (LoD) of RT-qPCR in each type of sample. We collected paired NPS and saliva samples and tested them using the Berlin Protocol to detect SARS-CoV-2 envelope protein (E). We used a Bayesian latent class analysis (BLCA) to estimate the sensitivity and specificity of each test, while accounting for their conditional dependence. The LoD were 10 copies/mL in saliva and 100 copies/mL in NPS. Paired samples of saliva and NPS were collected in 412 participants. Out of 68 infected cases, 14 were positive only in saliva. RT-qPCR sensitivity ranged from 82.7 % (95 % CrI: 54.8, 94.8) in NPS to 84.5 % (50.9, 96.5) in saliva. Corresponding specificities were 99.1 % (95 % CrI: 95.3, 99.8) and 98.4 %(95 % CrI: 92.8, 99.7). SARS-CoV-2 RT-qPCR test in saliva specimens has a similar or better accuracy than RT-qPCR test in NPS. Saliva specimens may be ideal for surveillance in general population, particularly in children, and in healthcare or other personnel in need of serial testing.

Respiratory syncytial virus (RSV) and rhinovirus (RV) are major causes of acute respiratory infections (ARIs) worldwide. The circulation of both RSV and RV was notably altered during the COVID-19 pandemic. This study analyzed the epidemiological and molecular characteristics of RSV and RV in Santander, Colombia, during the pandemic period (PP, 2020–2021) and the post-pandemic period (PPP, 2023–2024). A total of 921 respiratory samples from patients with ARIs were screened for RSV-A/B and RV. Sequences of the RSV attachment glycoprotein (G) gene and the RV VP4–VP2 region were analyzed in positive samples. Epidemiological and clinical characteristics of the study population were also assessed. RSV was not detected during PP, whereas RV was detected in 4.8% of samples. During PPP, RSV-A, RSV-B, and RV were detected in 5.6%, 4.4%, and 28.0% of samples, respectively. RSV infections were mainly identified in children, while RV was detected across all age groups. RSV-A sequences grouped within seven A.D-derived lineages (A.D.1.5, A.D.1.7, A.D.1.8, A.D.3.2, A.D.3.3, A.D.5.1, A.D.5.2), whereas RSV-B sequences clustered within the B.D.E.1 lineage. RV showed a higher number of detected genotypes during the PPP than during the PP. The genotypic characterization performed in this study provides new insight into the molecular epidemiology of RSV and RV in Santander, Colombia, during PP and PPP, and represents, to our knowledge, the first regional description of RSV lineages and RV genotypes across these periods.

En el presente manuscrito se presenta un análisis exhaustivo de las recomendaciones mundiales sobre inmunización en pacientes con errores innatos de la inmunidad. Se examinaron los mecanismos de acción y los tipos de vacunas, y se describieron las vacunas incluidas en el Plan Ampliado de Inmunización (PAI) colombiano y las pautas específicas para la inmunización de pacientes con los errores innatos de la inmunidad más frecuentes en Colombia.Estas recomendaciones se ajustaron según la gravedad y la subclasificación de cada inmunodeficiencia, teniendo en cuenta las variaciones en la respuesta inmunitaria, con el objetivo de ofrecer recomendaciones basadas en la evidencia clínica para la vacunación de niños con estas condiciones. Se contemplaron los errores de la inmunidad más comunes a nivel global y las vacunas incluidas en el PAI colombiano, para evitar retrasos en los esquemas de vacunación.Todo esto se logró mediante una revisión narrativa, no sistemática, de artículos indexados en español y en inglés, buscados con los términos MeSH: “errores innatos de la inmunidad”, “inmunodeficiencias primarias”, “vacunación en errores innatos de la inmunidad”, “tipos de vacunas”, “mecanismo de acción de las vacunas” y “vacunas vivas en errores innatos de la inmunidad”.Se emplearon motores de búsqueda como: PubMed, Medline, ScienceDirect y páginas web de instituciones reconocidas como Centers for Disease Control and Prevention (CDC).

CGD is an inborn error of immunity caused by pathogenic variants in genes encoding the phagocyte NADPH oxidase complex. In a multicenter cohort of 39 Colombian patients, we define clinical, microbiological, and genetic features, expanding the regional variant spectrum and highlighting the need for earlier diagnosis and improved access to specialized testing.
