Researchers have developed a prototype vaccine to fight against the deadly Middle East respiratory syndrome coronavirus (MERS-CoV). The study that is still under development display a promising result in line with the increasing number of cases of the outbreak in Riyadh.

Researchers found that the vaccine can protect monkeys and camels against the disease. With this finding, the vaccine can be a valuable tool guard individuals from being at risk of MERS. It can also be used to immunize camels in order to prevent the disease from spreading to human populations.

In the study published in the journal Science Translational Medicine, the researcher conducted several trials to test the vaccine on blood samples taken from camels which helped in the production of antibody proteins that can help fight against the deadly virus.

It was also tested on macaque monkeys which were then exposed to MERS. Surprisingly, the monkeys did not became ill.

According to Prof Andrew Easton of Warwick University, the data they collected from laboratory studies indicate that the vaccine can generate protective antibodies. The progress can help those who are now suffering from the disease. Health workers stated that they wanted to help patients to recover quickly but they don't have the right vaccine yet. With the new prototype vaccine, the outbreak can be ended.

Recently the number of infected individuals in Riyadh grew by six. The Ministry of Health of Saudi Arabia confirmed that the cases increased since July 21 in the region to 81.

A 109-year-old man was hospitalized along with five other patients. The King Abdulaziz Medical City posted on its official Twitter account that it is now controlling the spread of the virus by postponing most of its outpatient appointments.

The researchers which are led by University of Pennsylvania are now doing their best to find cure for the deadly camel flu.
