Where we are with vaccines and treatments for Covid-19

Published Aug 14, 2020


DURBAN - Normally it takes years to develop a safe and effective vaccine. As Coronavirus continues its terror across the globe, Scientists are moving at an unprecedented speed to

develop a vaccine that will be effective against Covid-19 sooner than later.

While this might be a welcome relief to the billions of people whose lives have been upended by the pandemic, the media has been urged not to amplify false hope when reporting about Covid-19 vaccines.

Speaking at an

online panel

This phase is what Scientists regard as critical because it determines whether a vaccine it’s safe or effective. The Sputnik V which Russia’s President Vladimir Putin announced as the world’s first Covid-19 vaccine hasn’t been through the full gamut of tests. There is currently no available data from phase one and phase two. Without data, scientists don’t know how safe it is.

However, what is known is that the vaccine is based on the DNA of a SARS-CoV-2 type adenovirus, a common cold virus. The vaccine uses the weakened virus to deliver small parts of a pathogen and stimulate an immune response.

Meanwhile, the World Health Organization (WHO) said it would need to review the vaccine’s safety and efficacy data in order to give the vaccine approval and the full go-ahead for large-scale production.

more than 165 vaccines

against the coronavirus, and 31 vaccines are in human trials. Drug companies Pfizer and Moderna last month both began late-stage trials for potential coronavirus vaccines, which are both expected to include up to 30,000 participants.
