BCG - vaccination- a new hope for countries implementing it

Correlation between universal BCG vaccination and reduced morbidity and mortality for COVID- 19 : AN EPIDEMIOLOGICAL STUDY. Aaron Miller , Mark Josh Reandelar , Kimberly Fasciglione , Violeta Rousmenova, Yan Ali and GonzaloH.Otazu DEPARTMENT OF BIOMEDICAL SCIENCES, NYOT COLLEGE OF OSTEOPATHIC MEDICINE, NEW YORK INSTITUTE OF TECHNOLOGY, OLD WESTBURY, NEW YORK, USA For complete study - Correspondence- gotazual@nyit.edu COVID- 19 has spread to most countries in the world. Puzzlingly, the impact of the disease is different in different countries. These differences are attributed to differences in cultural norms, mitigation efforts and health infrastructure. Here we propose that national differences in COVID- 19 impact could be partially explained by the different national policies in respect to Bacillus Calmette Guerin (BCG) childhood vaccination. BCG vaccination has been reported to offer broad protection to respiratory infections. We compared large number of countries BCG policies with morbidity and mortality for COVID- 19 .We found that countries with out universal policies of BCG vaccination ( Italy , USA , Netherland)have been more severely affected compared to countries with universal and long standing BCG policies. Countries that have a late start of universal BCG policy (Iran- 1984 ) had high mortality, consistent with the idea that BCG protects the vaccinated elderly population. We also found that BCG vaccination also reduced the number of reported COVID- 19 cases. BCG vaccination is a potential new tool in the fight against COVID- 19 .Japan had one of the early cases of COVID- 19 , but it has maintained a low mortality rate, despite not implementing the most strict forms of social isolation. Japan has been implementing BCG vaccination since 1947 . Why did COVID- 19 spread in China despite having a universal BCG policy since the 1950's ? .During the cultural revolution (1966- 1976) , tuberculosis prevention and treatment agencies were disbanded and weakened. We speculate that this,could have created a pool of potential hosts,that would be affected by and spread COVID- currently,however the situation in china,seems to be improving

In one of the indian study it has been postulated that in B.C.G vaccination persons- certain mutation occurs in the virus which makes is less virulent which do not reduce the transmission of disease and morbidity- but mortality is less as compared in non - vaccinated persons
Poor country like India stands tall in this respect Still it appears hypothetical but it will go a long way solution to dragon
Sir - it is not hypothetical as this study has been conducted by a reputed study centre in New York and study there is always evidence based unlike in india
