Vaccination for children is essential for preventing various infectious diseases and ensuring public health. Vaccines help build immunity by exposing the body to a harmless form of the virus or bacteria. Key vaccines recommended for children include: DTaP: Protects against diphtheria, tetanus, and pertussis. MMR: Protects against measles, mumps, and rubella. Polio: Prevents poliomyelitis. Hib: Protects against Haemophilus influenzae type b, which can cause serious infections. Hepatitis B: Protects against hepatitis B virus. Varicella: Prevents chickenpox. Flu: Annual vaccination recommended for influenza. Vaccination schedules may vary by country, so it's essential for parents to consult with healthcare providers to ensure children receive the appropriate vaccines on time. Vaccines are generally safe, and side effects are usually mild.
