COVID-19 Updated Guidance


Prioritizing Boosters for Pregnant People

Please review the CMOH’s Memorandum re: Prioritization of booster vaccines in pregnancy (Jan 4, 2022).

The CMOH is asking clinicians caring for pregnant people to “strongly encourage their patients to get vaccinated, including their booster dose to prevent risk of severe outcomes with Omicron. In addition, vaccine clinics in primary care and acute care are being asked to prioritize appointments for pregnant people “to facilitate their timely receipt of their booster vaccine due to the current epidemiology in the province”.

Information on COVID-19 vaccines in pregnancy is available on the Ontario Government website and on BORN Ontario’s website.

Guidance for vaccination during pregnancy can be found on page 2 of the COVID-19 Vaccination Recommendations for Special Populations document.


Pfizer Supply

The Pfizer-BioNTech vaccine is still in short supply provincially. TBDHU is actively managing our limited supply to ensure priority groups receive Pfizer-BioNTech vaccine (e.g. 12-17 year olds in high risk communities).

Please continue to reserve Pfizer for clients aged 12 to 29.


Call-out for Immunization Support - Routine Immunizations

TBDHU is still asking immunizers in our area to assist with completing infant and school aged immunizations for children without a health care provider.

Clients will be referred by TBDHU to partnering providers during the months of January and February, and follow up immunizations will be completed by TBDHU when capacity increases.

COVID-19 Testing Changes

On December 30, 2021, the Ontario Ministry of Health announced updated eligibility for PCR testing and case and contact management guidance. Key changes include:
  • Effective December 31, 2021, PCR testing will only be recommended for individuals if they belong to certain groups, which are listed in the Integrated Testing & Case, Contact and Outbreak Management Interim Guidance: Omicron Surge document.
    • Symptomatic testing will be available for high-risk individuals, and individuals who work in high-risk settings.
    • Other groups are listed and are based on risk level.
  • Individuals with symptoms consistent with COVID-19 are presumed positive and they should follow isolation and/or self-monitoring guidelines.
  • Testing for asymptomatic contacts of cases is generally no longer recommended, except for high-risk contacts/individuals that are part of confirmed or suspected outbreaks in high-risk settings, as recommended by public health.
  • Positive rapid antigen tests will no longer require PCR confirmation.
  • Rapid Antigen Tests are in short supply and are being prioritized for health care and highest risk settings.
Individuals who think they have COVID-19 or have been or exposed to the virus should check the Ontario website to find steps to take, including information for close contacts.
