Starting in the spring of 2024, NACI recommends that the following individuals who are at increased risk of severe illness from COVID-19 may receive an additional dose of XBB.1.5 COVID-19 vaccine:

  • Adults 65 years of age and older
  • Adult residents of long-term care homes and other congregate living settings for seniors
  • Individuals 6 months and age and older who are moderately to severely immunocompromised (due to an underlying condition or treatment)

(Discretionary NACI recommendation)

  • The added benefit of a spring COVID-19 vaccine program will depend on a number of factors; information on some of these factors is not yet available and may also vary by jurisdiction. Table 2 identifies factors that support a spring program and considerations that are currently unknown.
