Recommended Vaccines for a 23-Year-Old Male

A healthy 23-year-old male should receive annual influenza vaccination, ensure completion of the Tdap/Td series with boosters every 10 years, verify MMR immunity (1-2 doses if born in 1957 or later), confirm varicella immunity (2 doses if born in 1980 or later), and consider HPV vaccination (2-3 doses, routinely recommended through age 21, may be given through age 26). 1

Core Routine Vaccinations

Influenza Vaccine

  • Annual influenza vaccination is recommended for all adults 19 years and older, including healthy individuals 1
  • Either inactivated influenza vaccine (IIV) or recombinant influenza vaccine (RIV) should be administered annually 1
  • Live attenuated influenza vaccine (LAIV) is also an option for this age group 1

Tetanus, Diphtheria, and Pertussis (Tdap/Td)

  • One dose of Tdap should be given if not previously received, followed by Td or Tdap booster every 10 years 1
  • If the primary vaccination series was never completed, the first 2 doses should be given at least 4 weeks apart, with the third dose 6-12 months after the second 1
  • Tdap is particularly important for those anticipating contact with infants 2

Measles, Mumps, and Rubella (MMR)

  • Adults born in 1957 or later should have documentation of 1 or more doses of MMR vaccine unless they have laboratory evidence of immunity 1
  • A second dose may be indicated depending on occupation (healthcare workers) or travel plans 1
  • For males at age 23, at least one dose should be confirmed 1

Varicella (Chickenpox)

  • Two doses of varicella vaccine are recommended for adults born in 1980 or later without evidence of immunity 1
  • Evidence of immunity includes: documentation of 2 doses at least 4 weeks apart, U.S. birth before 1980 (except healthcare personnel), history of varicella disease verified by a provider, or laboratory evidence of immunity 1
  • Special consideration should be given if the patient is a healthcare worker, teacher, college student, or military personnel 1

Age-Specific Considerations

Human Papillomavirus (HPV)

  • HPV vaccination is routinely recommended through age 21 for males 1
  • Males aged 22-26 years may be vaccinated based on individual circumstances 1
  • The vaccine is given as a 2 or 3-dose series depending on age at initial vaccination 1
  • HPV4 is specifically recommended for men who have sex with men through age 26 for those who did not receive all doses when younger 1
  • Immunocompromised individuals should receive the vaccine through age 26 1

Meningococcal Vaccines

  • Meningococcal B (MenB) vaccination is recommended for individuals aged 19-23 years based on shared clinical decision-making 1
  • This is particularly relevant for college students, military personnel, or those living in close quarters 1
  • MenACWY may be indicated based on specific risk factors 1

Risk-Based Vaccinations to Assess

Hepatitis A and B

  • Hepatitis A and B vaccines should be administered based on risk factors including travel, occupation, lifestyle factors, or chronic medical conditions 1
  • The series consists of 2-3 doses depending on the specific vaccine used 1

Pneumococcal Vaccines

  • Generally not routinely recommended at age 23 unless specific medical conditions are present (asplenia, immunocompromising conditions, chronic heart/lung disease, diabetes) 1

Important Clinical Pitfalls

Common vaccination gaps in young adult males include:

  • Failure to receive Tdap booster (many received only childhood DTaP) 2
  • Incomplete varicella vaccination series 1
  • Missing HPV vaccination opportunity, particularly for men who have sex with men 1
  • Lack of documentation of MMR immunity 1

Key assessment points:

  • Verify vaccination history with documentation, not just patient recall 3
  • For college students or military personnel, ensure meningococcal vaccination is current 1
  • Assess occupational risks (healthcare workers require additional vaccines) 1
  • Screen for high-risk behaviors that would indicate need for hepatitis A/B vaccination 1
