Coronavirus vaccine in foray? Researchers say the rollout could take time

Delhi: Amidst the recent 2019 Novel Coronavirus (2019-nCoV) outbreak that has reportedly claimed the lives of more than 360 people in China, the researchers and labs worldwide are making continuous efforts to craft a vaccine for the deadly virus. 

According to the researchers, an effective vaccine could be created in a matter of weeks, using advanced techniques. Any new vaccine will still face manufacturing and regulatory hurdles that would take months to surmount. 

Coronaviruses (nCoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus is a new strain that has not been previously identified in humans. Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, the infection can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death.

The Wuhan coronavirus outbreak has already been declared a global public health emergency by the World Health Organization. 

The high-profile efforts at developing a coronavirus vaccine include:

Getting millions of doses of coronavirus vaccine into the hands of doctors and the arms of patients is a more complicated process, said Florian Krammer, a professor of vaccinology at the Icahn School of Medicine at Mount Sinai, in New York City.

The problem is that there are no vaccines on the market for any coronavirus, not even SARS or MERS, Krammer said.

If this were the flu, manufacturing could be more easily spun up because the technology is in place to mass-produce the annual flu vaccine, Krammer said.

"The truth is it's going to take a few months until there is a vaccine available for testing," Krammer concluded. "Then the main question that remains is how long it will take to produce, once the U.S. Food and Drug Administration allows its use in the population. How much time do we need to make sufficient doses?"
