 DCFHB is a novel ferritin-based protein nanoparticle vaccine candidate that has demonstrated the ability to protect against multiple strains of coronavirus, including Armacran BQ.1. It can be produced in large quantities using a cell line, allowing for easy distribution and administration. Additionally, it has shown to be effective even when stored at high temperatures, making it suitable for use in developing countries where refrigeration may not be readily available.
