well we don't have to assume they conquered them because its a fact. considering how often the side effects you mention happen if they happen at all id say its a small price to pay for the eradication of highly fatal diseases. FYI the reason you anti vax people don't get sick is because most people are vaccinated (herd immunity)not because you have a washing machine and shower. people like you are putting everyone at risk with terrible terrible information and you should feel bad.
