What is the primary way viruses are combated through preventive measures?

Vaccinations are considered the primary preventive measure against viruses because they stimulate the immune system to recognize and combat specific viral pathogens before infection occurs. Vaccines work by introducing a harmless part or a weakened form of the virus into the body, training the immune system to respond effectively. This preparation enables the body to mount a rapid and effective response if it encounters the actual virus in the future, thereby preventing disease onset.

While hygiene practices, antiviral drugs, and public health campaigns are important components of disease prevention and control, they serve to support vaccinations rather than replace them. Hygiene practices can help reduce the spread of viruses but do not provide long-term immunity. Antiviral drugs are typically used to treat infections after they occur rather than prevent them. Public health campaigns are crucial for education and awareness but rely on vaccination strategies for effective viral disease control at the population level.
