OVERVIEW

 * A large body of evidence suggests that vaccines are safe and effective
   against COVID-19.
   
 * All viruses evolve over time through genetic variations. These changes can
   cause the emergence of new “variants” of the original virus and may have
   different properties than the original virus, such as increased
   transmissibility or the ability to cause more severe disease. Omicron, along
   with its sub-variants, is the currently circulating variant of concern (VOC)
   in Alberta.
   
 * Omicron has demonstrated increased transmissibility and capacity to evade the
   body’s immune response compared to previous versions of the virus. This
   occurs whether this immunity was generated by infection, vaccines or both.
   
 * The protection that vaccines provide against severe disease continues to be
   strong even many months after immunization. Two doses of a COVID vaccine
   dramatically reduce the risk of hospitalization or death, and a third dose
   will offer even more protection. A booster dose is recommended at 5 months
   after the second dose, and at least 3 months following infection with
   COVID-19, to increase the level of protection against severe outcomes.
   
 * COVID vaccines are not always able to provide protection against infection by
   Omicron or one of its subvariants. Immunity against infection wanes over
   time, but can be boosted with a third or fourth dose of an mRNA vaccine.
   
 * Fourth doses, or second boosters, add additional protection and are most
   important for those at high risk of severe outcomes. For considerations on
   these doses, see
   https://www.alberta.ca/article-choosing-a-second-vaccine-booster.aspx


THE EVIDENCE

A systematic review of the evidence published between December 2021 and April
2022 in The Lancet Infectious Diseases found that the VE of a primary series
(for most people, this is two doses) against severe outcomes remained high and
stable over time at over 80%. [1, 2] VE against infection by Omicron was lower
than for previous variants and waned over time with most protection against
infection lost by 4-6 months post second dose. However, boosting with a third
dose increased the VE against infection with Omicron (to about 60%) and against
severe outcomes (to 90%). [1, 2]

The figure on page 20 of this document helps to illustrate the results from the
evidence, for both the primary series as well as for a booster dose.

Another evidence review published by McMaster University on June 22, 2022, also
examined the effectiveness of COVID-19 vaccines against the Omicron variant with
similar conclusions. It found that in general, people with a primary series
continue to have a good level of protection against hospitalisation and death
due to COVID-19 for at least 7 to 8 months after being vaccinated. A third
(booster) dose increases this protection against COVID-19 related
hospitalisations, with a very minimal degree of waning after several months. [3]

In addition to reviews that assess the VE of second and third doses, there is
emerging evidence on the benefit of a fourth dose. A recently published study in
healthcare workers from Israel found that only 7% of those with a fourth dose
became infected with Omicron, versus 20% of those with only three doses,
demonstrating increased protection against infection. Infections were either
asymptomatic or mild and no severe outcomes were seen. [4]

Note that this data is current up to August 5, 2022 and will be updated
periodically as new information emerges.

Leaflet
Geographies can be displayed by municipality or local geographic area (LGA).
When viewing by municipality, regions are defined by metropolitan areas, cities,
urban service areas, rural areas, and towns with approximately 10,000 or more
people; smaller regions (i.e. villages, and reserves) are incorporated into the
corresponding rural area. Cases without a postal code or incorrect postal codes
are not included. LGAs are sorted into 0-30, 30-60, 60-90, and 90-100% cut
points for the range of rates across regions. E.g. 10% of the LGAs with the
highest 7-day case rate will fall into the “Highest” category and 30% of the
LGAs with the lowest 7-day case rate will call into the “Low” category.

SUMMARY

NOTE: People are identified as COVID-19 cases prior to variant of concern
identification. As such, variant of concern reporting is delayed compared to
date the case was reported to Alberta Health.

Due to the large number of positive COVID-19 cases, the lab screened a sample of
positive cases between May 1, 2021 and May 31, 2021, September 9, 2021 and
November 23, 2021, and December 23rd, 2021 and February 9, 2022.

PROJECT DETAILS

The Alberta Wastewater Surveillance Program is a collaboration between the
University of Calgary, University of Alberta, Alberta Precision Labs, and
Alberta Health. SARS-CoV-2 virus has been demonstrated to be passed in the feces
of a significant proportion of infected individuals, individuals infected with
COVID-19 may pass the virus in their feces before they become asymptomatic. As
such wastewater can provide an early indication of infection trends in a
community. Wastewater monitoring is one of many tools in understanding the
overall burden of infection in a community, and provides a broad picture of
infection in a community.

More details on this project and additional wastewater data can be viewed on the
University of Calgary’s Centre for Health Informatics’ COVID-19 wastewater
dashboard

Wastewater Data is updated with the most current data delivered to Alberta
Health. This data is received around the same time data is updated on the
University of Calgary’s CHI Health tracker Monday, Wednesday, and Friday
afternoons. These data are incorporated into Alberta Health wastewater reporting
on the next scheduled reporting date. As such, there may be short and temporary
discrepancies between the wastewater data displayed between the two websites.
For more information on wastewater data interpretation, see the Data Notes tab.





Data are subject to change. Fluctuations are expected as cases are investigated
and updated. Data are provided for export in csv format.

DATA SOURCES

The Provincial Surveillance Information system (PSI) is a laboratory
surveillance system which receives positive results for all Notifiable Diseases
and diseases under laboratory surveillance from Alberta Precision Labs (APL).
The system also receives negative results for a subset of organisms such as
COVID-19. The system contains basic information on characteristics and
demographics such as age, zone and gender. The Communicable Disease Reporting
System (CDRS) at Alberta Health and the Communicable Disease Outbreak Management
(CDOM) system at Alberta Health Services contains information on COVID-19 cases.
Data Integration and Measurement Reporting (DIMR) database at Alberta Health
Services contains up to date information on people admitted and discharged from
hospital in Alberta. Information such as hospitalizations and ICU admissions are
received through enhanced case report forms sent by Alberta Health Services
(AHS).

COVID-19 vaccinations and AEFIs are reported to the Provincial Immunization and
Adverse Reaction to Immunization (Imm/ARI) repository. In Alberta, all health
practitioners are required by law to report Adverse Events Following
Immunization (AEFI) to Imm/ARI. The reporting requirements are outlined in the
Immunization Regulation, under the Public Health Act. Case definitions are
further defined in the AEFI Policy. As of January 1, 2021, all health
practitioners are required to report all (both provincially funded and privately
purchased) vaccinations electronically to Imm/ARI.



WASTEWATER SURVEILLANCE DATA

Due to differences in Wastewater composition across the province, data should
not be compared between municipalities. Instead, good practice when analyzing
wastewater data is to look at the general trend within a community. Two SARS
CoV-2 gene targets, the N1 and N2 genes, are tested for in the wastewater. The
average signal in gene copies/mL is presented.



DEFINITIONS

COVID-19 DEATHS

A death resulting from a clinically compatible illness, in a probable or
confirmed COVID-19 case, unless there is a clear alternative cause of death
identified (e.g., trauma, poisoning, drug overdose).

A Medical Officer of Health or relevant public health authority may use their
discretion when determining if a death was due to COVID-19, and their judgement
will supersede the above criteria.

A death due to COVID-19 may be attributed when COVID-19 is the cause of death or
is a contributing factor.




LAB POSITIVITY

COVID-19 percent positivity in Alberta is calculated using the Test Over Test
method, which is the same method employed by the US Centers for Disease Control
and Prevention. The calculation is as follows:

Daily Number of Positive Tests / (Daily Number of Positive Tests + Daily Number
of Negative Tests) Q/RT-PCR tests are the only COVID-19 tests included in this
calculation.

https://www.cdc.gov/coronavirus/2019-ncov/lab/resources/calculating-percent-positivity-faq.html




PRE-EXISTING CONDITIONS

The following pre-existing conditions are included in respective analyses:
diabetes, hypertension, COPD, cancer, dementia, stroke, liver cirrhosis,
cardiovascular diseases (including IHD and congestive heart failure), chronic
kidney disease, and immuno-deficiency diseases.




VACCINE COVERAGE

Individuals who received at least one dose was calculated as (# of individuals
who received at least one dose) / (population estimate). Those who received two
doses was calculated as (# of individuals who received two doses) / (population
estimate).

As of January 19, 2022 all doses administered in First Nations communities are
submitted directly into Imm/ARI and the data reconciliation resulted in the
removal of approximately 20,000 doses.




OUTBREAKS

Reporting for outbreaks vary by site/location and time, please visit here for
more details on the latest definitions.





DISCLAIMER

The content and format of this report are subject to change. Cases are under
investigation and numbers may fluctuate as cases are resolved. Data included in
the interactive data application are up-to-date as of end of day August 08,
2022.
