June 17 2021 – Ottawa Public Health (OPH) encourages Ottawa residents to take the first COVID-19 vaccine available for your second dose to provide earlier two-dose protection which is recommended where variants of concern are circulating.
On June 1, the National Advisory Committee on Immunization (NACI)updated its recommendations on the interchangeability of COVID-19 vaccines used in Canada. This means that you could receive one vaccine for your first dose and a different vaccine for your second dose to complete your COVID-19 vaccine series.
Interchanging vaccines is safe and effective and is not a new practice. Similar vaccines from different manufacturers are used when vaccine supply or public health programs change. Different vaccine products have been used to complete a vaccine series for influenza, hepatitis A, and others.
The priority is to receive two doses of a vaccine to complete the series and be fully protected. Both mRNA vaccines, Moderna and Pfizer, are made the same way. Getting the same vaccine for your first and second doses or getting one vaccine for your first dose and a different vaccine for your second dose (also called a “mixed schedule”), are both considered valid options.
Moderna and Pfizer have very similar effectiveness and side effects. The best vaccine you can get is the first one that is available to you and a second dose of a COVID-19 vaccine is needed for the best protection against COVID-19 and its more transmissible variants. All COVID-19 vaccines approved for use in Canada are safe and effective and they all reduce the risk of serious illness, hospitalization, and death, and will help with the control of COVID-19 in the community.
If you received AstraZeneca/COVISHIELD as your first dose, NACI recommends that you receive either AstraZeneca/COVISHIELD vaccine or an mRNA vaccine, such as Moderna or Pfizer, for your second dose.For more information on mixed vaccine schedules, please review NACI’s Interchangeability of Authorized COVID-19 Vaccines.Note that Ontario no longer offers AstraZeneca vaccine for those who have not received a first dose of AstraZeneca. For further information please contact your primary care provider.
