UPDATED: COVID-19 vaccine and other vaccines spacing recommendations
 
Consideration of COVID-19 vaccine administration is required when assessing patients/clients for other vaccines and vice versa. In the absence of evidence, the National Advisory Committee on Immunization (NACI) has published the following recommendations:
  • COVID-19 vaccines should not be given simultaneously with any other vaccines.
  • Wait for a period of at least 28 days between the administration of the a dose of COVID-19 vaccine and the administration of another vaccine (except in the case where another vaccine is required for post-exposure prophylaxis).
  • Wait for a period of at least 14 days after the administration of another vaccine before administering a COVID-19 vaccine.
  • If another vaccine is recommended or required between dose 1 and dose 2 of a COVID-19 vaccine series, it may be administered 28 days after the first dose of COVID-19 vaccine and at least 14 days before the second dose of COVID-19 vaccine is given.
These recommendations are based on:
  • the potential for immune interference, and
  • the need to monitor for potential COVID-19 vaccine adverse events without the potential confounding effects from adverse events following other vaccines.
