There are actually two coronaviruses -- which will make developing a vaccine harder: report

While researchers are already hard at work on developing a coronavirus vaccine, experts say it is unlikely to be ready for at least a year.
One of the reasons for that might be that it turns out, technically, there are two strains of coronavirus — and people can be infected with either, or even both simultaneously.
That’s according to a new study reported by The Telegraph.
“Researchers at Peking University’s School of Life Sciences and the Institut Pasteur of Shanghai, discovered the virus has evolved into two major lineages — dubbed ‘L’ and ‘S’ types,” stated the report. “The older ‘S-type’ appears to be milder and less infectious, while the ‘L-type’ which emerged later, spreads quickly and currently accounts for around 70 per cent [sic] of cases.”
