But such speculation needs to be tested  we cant just rely on an educated guess. Additionally, more research is needed to determine whether similar findings would emerge among a larger group of patients in other parts of the world. Prof Paul Morgan, the director of the Systems Immunity Research Institute at Cardiff University and a member of the British Society for Immunologys expert taskforce on immunology and Covid-19, said there were other reasons for optimism. The Indian researchers agreed that further studies using high antibody levels may find it to be more effective. However, data were still being collected in randomized controlled trials  the gold standard  to study the safety and effectiveness of the treatment.
