“…representing the most modified and highly attenuated strains deficient of methoxymycolic acids when compared to the Japan and Russia strains. [19][20] It is conceivable that the trained immunity induced by the Iran and China BCG vaccine strains are short-lived compared to those conferred by the widely utilized older strains.…”

The lower than expected number of SARS-CoV-2 cases in countries with fragile health systems is puzzling. Herein, we hypothesize that BCG vaccination policies adopted by different countries might influence the SARS-CoV-2 transmission patterns and/or COVID-19 associated morbidity and mortality through the vaccine's capacity to confer heterologous protection. We also postulate that until a specific vaccine is developed, SARS-CoV-2 vulnerable populations could be immunized with BCG vaccines to attain heterologous nonspecific protection from the new coronavirus.

Background: BCG is a vaccine obtained by attenuating Mycobacterium bovis. It is a fairly safe vaccine with no associated complications. Aim: To determine the frequency of accelerated BCG response in BCG vaccinated children. Study design: Descriptive case series. Methodology: A total of 124 already BCG vaccinated patients, having age in the range of 6 months to 10 years of either gender were included in the study. Patients with known case of TB and any other systemic disease were excluded. After this, BCG vaccination was given by the researcher himself who noted the in-duration after 72 hrs of BCG vaccination accelerated response of BCG. Chi square test was applied with P-value <0.05 as significant. Results: Mean age was 6.02±2.22 years. Out of the 124 patients, 63(50.81%) were male and 61(49.19%) were females. Mean duration of previous BCG was 4.75±2.41 years. Frequency of accelerated BCG response in BCG vaccinated children was found in 76(61.29%) patients. Conclusion: This study concluded that the frequency of accelerated BCG response in BCG vaccinated children was 61.29%. So, we suggested that public awareness programs should be arranged to educate people for compulsory BCG vaccination of their children. Keywords: Bacillus Calmette-Guerin (BCG) Vaccine, Accelerated BCG Response and Tuberculosis.
