"Anti-vaccine" refers to a movement or belief system that opposes the use of vaccines. People who identify as anti-vaccine often express concerns about vaccine safety, effectiveness, or the necessity of vaccinations. This perspective can lead to lower vaccination rates, which may contribute to the resurgence of preventable diseases. The anti-vaccine movement has gained attention through social media and various public figures. Some individuals may be influenced by misinformation or personal experiences, while others may hold philosophical or religious beliefs against vaccination. This has raised public health concerns, as widespread vaccination is crucial for maintaining herd immunity and preventing outbreaks of diseases like measles and whooping cough.
