Who wants to kill vaccines?

The vaccine, cʹest an individual act, but cʹest also an act for the collective well-being. We vaccinate for ourselves and for others, so as not to contaminate the most vulnerable among us: infants, the elderly or those with reduced immunity. Vaccinations have made it possible to control diseases that were once common in Switzerland: tetanus, polio, diphtheria, whooping cough, measles, German measles, mumps, hepatitis B and certain serious forms of meningitis. So why question these medical advances?
