Vaccines are essential tools in preventing the spread of infectious diseases and protecting individuals from serious illnesses. In Vancouver, vaccines play a crucial role in maintaining public health by immunizing individuals against various diseases such as influenza, measles, polio, and more. By introducing a small, harmless amount of a virus or bacteria into the body, vaccines stimulate the immune system to develop protection (antibodies) against that specific disease. Getting vaccinated not only safeguards the individual but also contributes to community immunity, protecting those who cannot be vaccinated, such as individuals with certain medical conditions or compromised immune systems. Vaccines are recommended for people of all ages, from infants to the elderly, and are administered by healthcare professionals following established vaccination schedules. It is important to stay informed about the recommended vaccines for different age groups and health conditions to ensure optimal protection against preventable diseases.
