As per recent studies, the BCG vaccine -- originally for tuberculosis (TB), can provide protection against COVID-19, and several infections such as leprosy and malaria.
A recent study has found that BCG TB vaccine can protect people against SARS-CoV-2 and lots of other pathogens.
The study, published in the journal Cell Reports Medicine on Monday, was conducted on 144 patients with type 1 diabetes at the start of the pandemic, much before COVID-specific vaccines were available.
In high-income countries, tuberculosis mainly affects the elderly, whereas in countries such as India, the disease each year takes the lives primarily of young and middle-aged adults, the most productive members of society.
According to the ICMR study, BCG vaccine shots induce enhanced innate and adaptive immunity among elderly patients who have tested positive for COVID-19, which may help in fighting the novel coronavirus infection.
Researchers have found that countries with mandatory BCG vaccination saw slower infection and death rates during the initial period of the COVID-19 outbreak.
About 6,000 health workers and high-risk individuals including those in close contact of COVID-19 patients have been enrolled in a clinical trial to determine if the recombinant Bacillus Calmette-Guerian (rBCG) can boost immunity to fight against the virus, the statement added.
Head of Epidemiology and Communicable diseases at the Indian Council of Medical Research (ICMR) Dr Raman R Gangakhedkar said that the apex health research body will begin a study on the effectiveness of the vaccine against coronavirus infection next week.
The study analysed dataset from 178 countries of COVID-19 cases and deaths recorded from March 9-24
