Adult Immunization

Adult immunization refers to the process of vaccinating adults against various diseases and infections to prevent illness, disability, and death. Vaccination is an essential tool for maintaining public health and preventing the spread of infectious diseases.

Purpose of Adult Immunization

The primary purpose of adult immunization is to:

  • Protect against serious and potentially life-threatening diseases such as influenza, pneumococcal disease, and hepatitis
  • Prevent the spread of infectious diseases in communities
  • Reduce the risk of complications and hospitalizations associated with vaccine-preventable diseases
  • Support herd immunity, which helps protect vulnerable individuals who cannot receive vaccines due to medical conditions or age

Recommended Vaccines for Adults

The following vaccines are recommended for adults:

  • Influenza vaccine: annual vaccination against seasonal flu
  • Tdap (tetanus, diphtheria, and pertussis) vaccine: booster dose every 10 years
  • TD (tetanus and diphtheria) vaccine: booster dose every 10 years
  • Pneumococcal conjugate vaccine (PCV): recommended for adults aged 65 and older, and for younger adults with certain medical conditions
  • Pneumococcal polysaccharide vaccine (PPSV): recommended for adults aged 65 and older, and for younger adults with certain medical conditions
  • HPV (human papillomavirus) vaccine: recommended for adults aged 27-45 who did not receive the vaccine as adolescents
  • Hepatitis A vaccine: recommended for adults with certain medical conditions or who are at increased risk of infection
  • Hepatitis B vaccine: recommended for adults with certain medical conditions or who are at increased risk of infection
  • Meningococcal conjugate vaccine (MenACWY): recommended for adults aged 55 and older, and for younger adults with certain medical conditions
