Solution
The substance produced by a cell in viral infection that can protect other cells from further infection is interferon.
Explanation:
Interferons are antiviral proteins secreted by virus-infected cells that help prevent the spread of the virus to neighboring cells by interfering with viral replication. They act as a warning signal to nearby cells to activate their antiviral defenses, thus protecting them from infection.
