BCG vaccination in infancy does not protect against COVID-19

Professor Clément de Chaisemartin published a paper on how the BCG vaccination relates to COVID-19 in Clinical Infectious Diseases, the journal from the Infectious Diseases Society of America.

The paper, titled "BCG vaccination in infancy does not protect against against COVID-19. Evidence from a natural experiment in Sweden," focuses on the Bacille Calmette-Guérin (BCG) tuberculosis vaccine, which has been speculated to bring immune protection against COVID-19.

Chaisemartin examines a 1975 experiment in Sweden involving newborns who had been vaccinated with BCG. The paper concludes that BCG, when administered at birth, does not have a protective effect on coronavirus later on in life.
