An interesting question is why a vaccine against a bacteria would be effective against a virus. From Joe Pinkstone at dailymail.co.uk:
- Previous studies suggested the BCG vaccine offers protection from Covid-19
- US researchers conducted a comprehensive review and found a clear link
- Say it is currently impossible to determine if it is causative or just a correlation
- But countries with a 10 per cent greater prevalence of the BCG vaccine also had a 10.4 per cent reduction in COVID-19 mortality
Bacillus Calmette-Guerin (BCG) was first mass produced in 1924, and widespread vaccination for secondary school children was only halted in the UK when TB was effectively eradicated.
Academics in the US compared the BCG jab’s popularity in several countries with each nation’s coronavirus outbreak — including both infections and deaths — and found a clear link between the vaccine and a lower mortality rate from Covid-19.
