What is a relationship between BCG vaccine and Coronavirus, and is true that any person taken the BCG vaccine have not affected with Coronavirus disease (COVID-19)?
It's preliminary finding; as isme countries where BCG vaccine is given at birth corona virus cases are less in no., Severe cases are also less and also the deaths.But clinical trials are going to find out the evidence.
It's an interesting observation of Corona and BCG vaccination, but it's just a priori hypothesis. I think it's just a chance unvalidated temporal association. Needs more robust clinical experimental data for the same.
It is too premature to comment. It is only because of geographical distribution this hypothesis is being projected. There is no scientific basis as of now
