Fear growth & spread

Who can reply on the question in the affirmative? The Vaccination applied to us worldwidely is really effective to countermeasure SARS CoV-2? Virus has an innate character to produce Mutant Strain one after another without interruption. The character of Virus, "Invisible Stealth" invite fear and horror excessively. Government choices change later, so it is not reliable as it does. People is available to receive many different opinions but no way to collect only correct ones. The more is not always the more correct information. Though we are in the Scientific World that has critical Truth and Fact, people are at a loss how, what, where, when, who to chose.
