Is there evidence that BCG vaccination has non-specific protective effects for COVID 19 infections or is it an illusion created by lack of testing?
Category: Article Summary
Topic: Testing and Treatment
- Shivendu et al analyze data from on COVID-19 and BCG vaccination from 98 countries, finding that COVID-19 cases deaths across countries share a relationship with national BCG vaccination, but that this relationship is nullified when controlling for testing.
- This study concludes that there is no statistical evidence to support the assertion that inclusion of BCG vaccination in NIP has an impact on COVID-19 incidence or mortality.
