A NYT article about the vaccine says as folllows:
To create Covaxin, Bharat Biotech used a sample of the coronavirus isolated by India’s National Institute of Virology. Once the researchers produced large stocks of the coronaviruses, they doused them with a chemical called beta-propiolactone. The compound disabled the coronaviruses by bonding to their genes. The inactivated coronaviruses could no longer replicate. But their proteins, including spike, remained intact.

How reliable is the chemical reaction? Does it bind to every single one of the virions or there could be a small amount - say 1% or 0.001% - which remains intact?
