Another very promising approach uses insights emanating from our ability to access and assess global data in very short periods of time. Several scientists have been voicing opinions based on educated guesses that those nations that have had vigorous BCG vaccination programmes seem to have been not so adversely affected by the COVID-19 crisis. This has—in all probability—led the WHO to conduct a web-based search on April 11. The strategy was to use the technical search terms and words COVID-19, coronavirus, SARS-CoV-2 and BCG in the English, French and Chinese languages to search scientific and technical databases. Earlier, such an exercise would have taken weeks, if not months, and it goes to demonstrate the power of IT based technology. In any case, this review did indeed yield three yet-to-be-reviewed research preprints that have indicated the possibility of a correlation between the use of the BCG vaccine and the lower incidence of COVID-19. The review also yielded information that two clinical trials are underway where frontline health workers are being given the BCG vaccine to test its efficacy in warding off coronavirus. Once again, the point that needs to be underscored is that human ingenuity and technology have come together to discover what could be an effective means of tackling the crisis. In fact, there is striking evidence that has just emerged through a study at the University of Texas at Houston that also involves an Irish medical consultant. This study has found that the BCG vaccine does significantly reduce the number of deaths due to COVID-19. They studied data from more than 178 countries and that is what makes it so compelling. The study includes countries such as Ireland and establishes that the reduction in the death rate due to COVID-19 is by a factor of 20 in those countries that have had a sound BCG vaccination programme. This is indeed very startling. India seems to have also put some store by these inferences since BCG related trials are already underway in the country. I have reason to believe that the BCG route is likely to be one of the most promising ones in the battle against COVID-19.
