Coronavirus vaccine: 4 infections apart from COVID-19 which still don't have a vaccine

Middle East Respiratory Syndrome (MERS), which spread out just like COVID-19 is yet another deadly pandemic which left its mark of casualties ever since originating in 2012. While it was mostly seen in the middle eastern nations, the only reason the world never saw the development of a vaccine was because the authorities were able to put in measures and stop the transmission of the disease in time. Ever since, only a few sporadic cases were seen and more or less, the infection could be contained. Interestingly, a very recent announcement regarding the development of a MERS vaccine was announced in April 2020 which could be repurposed to tackle the COVID-19 pandemic. According to researchers, the vaccine prototype, which works using an attenuated version of the virus showed promising results in clinical studies.
