A vakcináció is a medical process that involves administering a vaccine to help protect individuals from specific diseases. Vaccines work by stimulating the body's immune system to recognize and fight off pathogens, such as viruses or bacteria, without causing the disease itself. This helps to build immunity and can prevent the spread of infectious diseases within communities. Vaccination is an essential public health measure that has led to the control and even eradication of several diseases, such as smallpox and polio. It is recommended for people of all ages, with specific vaccines given at different stages of life, including childhood and adulthood, to ensure ongoing protection against various illnesses.
