Researchers in Costa Rica are due to begin trials of an inexpensive coronavirus treatment based on antibodies taken from horses injected with the SARS-Cov-2, the virus that causes Covid-19, Reuters reported while quoting scientists.

Developed by the University of Costa Rica's Clodomiro Picado Institute (ICP), the equine antibodies medication is to be tested on 26 patients from mid-September, Roman Macaya, president of the Social Security Fund that manages public health centres, told Reuters.
