As efforts to discover an effective vaccine for SARS-CoV-2 ramp up, an immunologist warns that fast-tracking of scientific trials might be disastrous.
Researchers around the world are working to develop an efficient vaccine for the unique coronavirus, SARS-CoV-2.
Till such a time, the world is reliant on physical distancing procedures and individual protective equipment (PPE). Some nations are using ‘track and trace’ systems to keep an eye on the motions of individuals and alert those who have actually been in contact with someone identified with COVID-19
Naturally, a treatment for COVID-19 is likewise highly desirable. Gilead’s anti-viral drug remdesivir appears to accelerate healing time in some people. The United States and the UK have now authorized its usage as a treatment for people with COVID-19
Nevertheless, as remdesivir is a treatment, not a cure, and some clinical trial outcomes show no substantial advantage, a vaccine remains more effective.
Although a COVID-19 vaccine is urgent, scientists can not hurry the advancement procedure. In a recent editorial, immunologist and deputy editor of the journal Science Advances Dr. Douglas J. Green explains why bypassing important medical trial phases for any such vaccine might be ‘devastating.’

The vaccine development procedure
There are presently 95 vaccines versus SARS-CoV-2 in development. After the discovery and pre-clinical development stages, each of these should advance through 3 phases of medical trials.
Phase I involves security screening in a little friend (e.g., 10–50 people). Phase II trials include investigating the immune response in a larger mate.
Stage III trials include much larger groups of people (in some cases in the thousands) and should show, in a statistically significant way, that the vaccine can protect against infection. This phase alone can take a number of years under typical scenarios.
In the context of the COVID-19 pandemic, this is too long to wait. The majority of price quotes indicate that a vaccine is 12–18 months away. This is because of structured procedures, such as accelerated pre-clinical screening and regulative review processes.
Some specialists have also promoted for ‘fast-tracking’ some clinical trial stages. They suggest that proof that a vaccine activates the production of neu
