Ask a Librarian: immunization awareness

COVID-19 safety measures across the country have impacted many aspects of care delivery, including access to routine immunizations for patients of all ages. In infants and toddlers especially, immunizations are essential to preventing vaccine-preventable disease outbreaks.

August is National Immunization Awareness Month, an occasion that highlights the importance of vaccination to protect patients of all ages. As a physician, you are a critical part of informing patients in their health decisions. As we head into flu season, you are ideally suited to provide them with evidence-based information on how vaccines work and recommendations for their specific immunization needs.

Did you know CMA members have access to skilled medical librarians? Our team of librarians can support you by searching on your behalf, teaching you effective search strategies or training you to use our resources. You’re getting the latest evidence and saving time, so you can focus on what’s important to you.

Here are some resources on immunizations selected by Joule’s Ask a Librarian team using a variety of tools included with a CMA membership.

Immunizations in Adults

Overview and Recommendations

Routine immunizations

  • For all adults:
    • An annual influenza vaccination is recommended for all adults (Strong recommendation).
    • Give Tetanus, diphtheria, and acellular pertussis (Td/Tdap) every 10 years (Strong recommendation).
      • For patients with lacerations that are more severe than clean minor wounds, give if it has been > 5 years from the last dose (Strong recommendation).
      • Give 1 dose of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine to pregnant women (with each pregnancy) and to other adults if Tdap had not been previously received (Strong recommendation).
    • Varicella vaccine is indicated for all adults without evidence of immunity to varicella; pregnant women who need immunization should be immunized as soon as they are no longer pregnant (Strong recommendation).
    • Give measles, mumps, and rubella (MMR) vaccination to all adults without immunity to MMR, including all adults born in 1957 or later who do not have documentation of ≥ 1 dose of MMR vaccine. Pregnant women who need immunization (especially to rubella) should be immunized as soon as they are no longer pregnant (Strong recommendation).
