Limited studies have been conducted on the safety and effectiveness of heterologous COVID-19 vaccine boosting in lower income settings, especially those with high-HIV prevalence., The Sisonke Heterologous mRNA-1273 boost after prime with Ad26.COV2.

The Indiscriminate Chemical Makeup of Secondary Metabolites Derived from Endophytes Harvested from Miller in South Africa's Limpopo Region.

The efficacy of 23 bacterial isolates obtained from surface-sterilized stems and leaves of three medicinal plants ( Miller, , and ) was investigated in an endeavour to prevent the growth of using the cross-streak method. Endophytes were isolated by incubating sterile plant materials on nutrient agar at 30 °C for 5 days. Two isolates showing activity were subsequently utilized to produce the extracts.
