you dont need data to see how these vaccines are helpful. just go talk to someone who contracted polio or hepatitis and ask them about how their quality of life is. they might have developed immunity naturally but they also have to face life long impairments like having the risk of developing liver cancer with hepatitis.
you all need to rethink this and use common sense. why would you want to FLOG a child's immunity during the 1st few months of life? ridiculous and borders malpractice
