Do vaccines actually protect against the viruses and illnesses that they claim to? If you only get your news and information from mainstream news and educational sources, then the question about whether vaccines are effective is never even raised. However, if you look at the historical data on vaccination efficacy, you'll see that they are not responsible for the decline in disease in the last hundred years at all:

testified along with other scientists that mass inoculation against
polio was the cause of most polio cases throughout the USA since 1961.
