Has anyone studied of SARS survivors to see if they show some immunity against Covid-19 infection? There is supposed to be considerable similarity between the two viruses. What does the serological test for Covid-19 antibodies indicate when tested on SARS survivors?

COVID-19 has many differences with SARS disease.
It could be new acute emerging disease that maybe has some similarity with SARS or MERS genome but virus behavior could be differ with some new findings completely.
Immunity Indicators, Viral load trajectories, Escape mutants, Disease prognosis and other important parameters should be investigated by interested researchers as soon as possible.

The T cells, along with antibodies, are an integral part of the human immune response against viral infections due to their ability to directly target and kill infected cells. A Singapore study has uncovered the presence of virus-specific T cell immunity in people who recovered from COVID-19 and SARS, as well as some healthy study subjects who had never been infected by either virus.
