Updated Key Findings
December 14, 2021
Ontario Immunization Advisory Committee recommended that if an 11 and 12-year-old child is inadvertently given a second dose of the Pfizer-BioNTech vaccine that is not authorized for their age, the dose should be considered valid and the series complete.
National Advisory Committee on Immunization (NACI) recommends that a booster dose of an authorized mRNA COVID-19 vaccine should be offered to vulnerable population and > 50 years old, =6 months after completion of a primary COVID-19 vaccine series.
Australian Technical Advisory Group on Immunization (ATAGI) recommends COVID-19 booster vaccination with either Pfizer (Comirnaty) or Moderna (Spikevax), which are considered equally acceptable, for anyone aged 18 and older who completed their primary course of COVID-19 vaccination 5 or more months ago.
On December 8th, 2021 in a press release by Pfizer-BioNTech said that preliminary laboratory studies demonstrate that three doses of the Pfizer-BioNTech COVID-19 vaccine neutralize the Omicron variant while two doses show significantly reduced neutralization titers. Data indicate that a third dose of BNT162b2 increases the neutralizing antibody titers by 25-fold compared to two doses.
Key Findings
December 3, 2021
The Therapeutic Goods Administration (TGA) has granted provisional approval to Moderna for the use of its vaccine in children (two 10µg doses) and as booster shot for adults (one 30µg dose) in preparation for the recent emergence of the Omicron variant. This is in addition to Pfizer, which was also recently approved.
The National Advisory Committee on Immunization (NACI) recommends that a complete series with the Pfizer-BioNTech COVID-19 vaccine (10 mcg) may be offered to children 5-11 years of age who do not have contraindications to the vaccine, with a dosing interval of at least 8 weeks between the first and second dose.
NNACI also recommends that children aged 5-11 years with a history of previous SARS-CoV-2 infection should be considered no longer infectious and symptoms of an acute illness should be completely resolved prior to vaccination.
Health Canada has authorized Moderna's COVID-19 vaccine (also known as Spikevax) to be used as a booster shot, using a half-dose of the vaccine.

Key Findings
Visitor restrictions in long-term care (LTC) during an outbreak or pandemic are implemented due to the perceived risk of transmission between residents or staff and visitors. · Social isolation and possible loss of care resulting from visitor restrictions in LTC may place residents at risk of poorer outcomes in terms of both physical and mental health, as well as distress to families and staff (see Saskatchewan LTC Network Family Perspective). · Visitor restriction policies typically allow visits for compassionate reasons that include end of life, critical care, and support of persons who require assistance beyond that provided by healthcare e.g. support for feeding, mobility, or behaviors, but specific detail on these is not consistent or clear. · Recent changes to visitation policies in Australia are less restrictive and allow brief visitations (end of table 1, noted in red font). · Although the majority of policies describe a need for flexibility and case-by-case assessment of visits deemed “essential”, the majority of policies are not clear in who is to conduct this analysis or the criteria that should be used to make these decisions. Visitation policies differ in detail regarding the number of visitors allowed at one time, total number of visitors allowed, visit duration, mobility within the home and location of the visit. · Remote and technology assisted visits are to be facilitated by LTC staff. · Infection control practices are enforced for visitors, and may include screening (e.g. temperature, symptoms, travel and contact history), prohibiting ill visitors, use of personal protective equipment (PPE), hand and cough hygiene. · Education of visitors and support for proper infection control practices is encouraged in the majority of policies.

Key Findings
Initial findings from RCTs of the two authorized COVID-19 vaccines (Pfizer-BioNTech and Moderna) reported that the vaccines are safe. However, subsequent reports show that the adverse and severe allergic reactions to these vaccines are higher than the general rates for vaccines.
Various regulatory agencies identify the risk for serious allergic reactions as low for the authorized vaccines, and they continue to monitor the vaccines’ safety closely.
Further investigations to make causal relationships with reported severe allergic reactions or deaths are needed.
Risks and benefits of receiving the vaccines should be discussed individually in vulnerable populations including pregnant or breast-feeding women, immunocompromised people, or frail elderly people.

Key Findings
January 12, 2022
The diagnostic accuracy of Rapid Antigen Tests (RAT) has been widely studied in various applications and in diverse populations.
Sensitivity, in the order of 75% in pooled estimates, is significantly influenced by the presence or absence of symptoms, viral load, and the timing of sampling relative to the onset of symptoms.
Specificity, in the order of 99% in pooled estimates, is consistently high across tests, populations, and sampling methods.
Post-test probability of being an infectious case following a positive test is highest in individuals with a high pre-test probability (population prevalence > 5%), such as those with COVID-19 symptoms, and those in settings with a high level of community transmission. Here, the positive predictive value is in the order of 95%. However, when used in settings with a lower pre-test probability (population prevalence < 0.5%), as in screening asymptomatic individuals, the positive predictive value is considerably reduced, as low as 25%.
Post-test probability of being an infectious case following a negative test is less than 1% (negative predictive value > 99%) in all settings except those with the highest levels of community transmission.
