Vaccination myths are common misconceptions about vaccines that can lead to fear and hesitancy. One prevalent myth is that vaccines cause the diseases they are meant to prevent. In reality, vaccines contain weakened or inactive parts of the virus or bacteria, which help the immune system recognize and fight the real pathogens without causing illness. Another myth is that vaccines are unnecessary because diseases are no longer common. While some diseases have become rare due to successful vaccination programs, they can resurge if vaccination rates drop. Maintaining high vaccination coverage is essential to protect public health and prevent outbreaks of diseases like measles and whooping cough.
