Vaccines protect people at every stage of life: from a child’s first days through adulthood and beyond. In early childhood, immune systems are still developing, leaving young children more vulnerable to serious illness. That’s why most routine vaccines are given in the first two years of life, offering protection when it matters most. As children grow into their teenage years, booster doses help keep that protection strong and respond to new and emerging health risks. During pregnancy, vaccination plays a crucial role in protecting both parent and baby. Recommended vaccines help pass protective antibodies to babies before birth, giving them a safer start in life. In adulthood and older age, the immune system naturally becomes less robust. Vaccines help reduce the risk of severe illness and hospitalization, helping people stay healthy and live longer. Vaccination is about care, prevention and giving every generation the chance to learn, grow and thrive www.who.int/campaigns/world-immunization-w... #VaccinesWork #WorldImmunizationWeek
