Professor Strunecká, author of the bestseller Doba jedová, offers in her new book on vaccination an understandable and clear explanation of the mechanisms of immunity and the consequences of vaccination. Detailed and true information about vaccines should be accessible to all citizens in a democratic state. In the same way, the right of every parent should be the freedom of informed consent for the vaccination of their children. Vaccination is an invasive medical procedure that can, even in rare cases, cause damage and even death in a fairly healthy person. More and more people desire objective and scientifically based information and are not going to rely only on what is recommended to us by advertisements, media or mandated by government authorities. There is still no similar book on the Czech book market. Readers will also find advice for parents on vaccinations from a general practitioner and a legislative section prepared by a lawyer according to the latest amendments to the Public Health Act.
