Quizplus · Accepted Answer

Viruses can only multiply inside living cells of a host organism. Once a virus enters a cell, it hijacks the machinery of the host cell to produce more viral particles. Traditional drugs that work against bacterial infections, such as antibiotics, are ineffective against viruses because they target specific structures or functions found only in bacteria. Antiviral drugs work by targeting specific steps in the viral life cycle, but they still face the challenge of penetrating the protective barriers of host cells to reach the virus. Vaccines work by stimulating the immune system to produce specific antibodies that can recognize and neutralize viral particles, but not all viruses are easily targeted by this approach.
