It's responsible for more than 250,000 deaths in the U.S. Two of the companies, in particular, that are trying to create a COVID-19 vaccine have stood out from the competition by employing a bold, still unproven process. This time, it just might work. The mumps vaccine was rolled out in 1967 in what is considered the fastest implementation in history. It took four years. The vaccine for this coronavirus (officially, the severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2) is on a much, much faster track, for a few reasons. One, scientists have seen a virus like this one before: The SARS outbreak in 2003 infected more than 8,000 people worldwide and killed nearly 800. This SARS-CoV-2 virus, it turns out, is 80 percent identical in genetic material to the one in 2003. All researchers needed this time was to see how this virus was different from the last one. The Chinese scientists who discovered the SARS-2 virus in January mapped its genomes almost immediately. However, pairing an organ that's likely to work given a patient's specific circumstances is complex, to say the least. Anne Huml, M.D., with Case Western Reserve University in an email interview. The data examined uncovered some unsettling trends. Sometimes a kidney comes along that could be a perfectly good match for the patient, but thee transplant center itself declines use of the organ for reasons that another program might not. Sumit Mohan, M.D. and Mariana Chiles, Ph.D. The findings have some pretty big implications for patients on the wait list, who typically spend long periods of time on dialysis waiting for a match. Huml says, noting that gender, race and socioeconomic disparities in access to kidney transplantation are nothing new. This study is the first to look at the refusal codes for deceased donor kidneys. Often, patients don't even know that kidneys are being offered and declined on their behalf. jay z net worth
