Canada becomes a model nation proving 2-dose vaccines work

After experiencing a horrific surge in COVID-19 cases in this past spring, Canada has upped the rate of vaccination hence dropping the number of daily deaths and active infections.

The one thing that has changed about Canadians’ behaviour, according to statistical evidence across Canada, is that Canadians are getting vaccinated in droves.

“Canadians will need to increase their 23% full vaccinated level very fast because even this Sunday we are beginning to see early evidence of big trouble ahead from the B.1.617.2.1 variant and its root, the Delta variant,” explained Dr. Fred Harris, a biostatistician and infectious disease researcher in Singapore with the CSPAC  group.

“Around the world, COVID-19 case sums and deaths are reported lower than actual for a number of reasons, particularly because its nearly impossible to know exactly in real time the number of unreported and asymptomatic cases,” said Dr. Harris.

Epidemiologists working with biostatisticians,” Dr. Harris continued, “are able to computerize mathematical equations that help estimate these actual numbers before the final data is finally calculated long after the pandemic is over. Even then, much data will rely in estimates.”

“Canada’s data are among the closest to actual estimates calculated by the IHME and CSPAC estimated COVID-19 computer-modelled sum of cases (in Canada: as of 19 Jul 2024), estimated sum of deaths (Canada: as of 19 Jul 2024), and the actual estimated current active cases (Canada:  as of 19 Jul 2024).

“What this information tells us is how and why surges can take place and what must be done and where, to end the pandemic,” he said.

“Huge numbers of people may become infected by SARS-CoV-2 variants and while never being reported and treated, are likely infecting a higher number of cases than hospitalized patients.

“The unknown infections in developing nations are the greatest obstacle to ending this SARS-CoV-2-caused Pandemic. Everyone must be vaccinated,” noted the scientist.

“In those countries where the difference between reported cases and the scientifically estimated cases by science groups like the Institute for Health Metrics and Evaluation, the gap is substantial.

“India is such a case where the underreported data are staggering. Cases, deaths and what scientists call the “R-nought” or R0 factor are grossly under reported in India,” he said.

“This causes huge vagaries in global calculations because the numbers are so far from reality. India admittedly only calculates and reports hospitalized cases, and even then, in a scanty fashion, according to a consensus among epidemiologists who rely on India’s regional data from traditional sources like hospitals, mortuaries, coroners and medical professionals, not to mention the thousands of bodies floating in rivers, which in total exceed what is reported,” continued the biostatistician.

In Canada, Vaccinations have reduced the reported COVID-19 Active Cases nearly in half over ten days in Canada despite Delta variant spread. Sum of deaths trend almost flatlines.

“This is very interesting,” said Harris.

“Thousands of Canadians have in many respects acted in a cavalier fashion, trying to lead people into the streets to protest against mask wearing and quarantine measures. Well, they became infected in large numbers. Those large numbers infected many more people. Canada was in a mess as one can see from the two major humps in the graph,” he explained.

“So, why is this important? Because while the government was having a hard time controlling so-called freedom-of-speech exercises, public disobedience, and superspreader events, it slammed down hard on educating the population on the safety requirement of getting vaccinated against the SARS2. Ottawa pushed the provincial governments to get the job done.

“At first cases continued to rise, but the illnesses lasted shorter periods and the case fatality rate plummeted. Then everything dropped as the vaccination levels rose.”

Here is the vaccination data for 26 June 2021.

  • Vaccine doses administered: 34,174,571
  • Fully vaccinated: 23.3%
  • Received at least one dose: 67.25%

Full vaccination is needed. Evidence from the United Kingdom about two of the above vaccines used in both countries are efficacious against some of the worst variants.

  • “The Pfizer-BioNTech vaccine is 96% effective against hospitalisation after 2 doses
  • “the Oxford-AstraZeneca vaccine is 92% effective against hospitalisation after 2 doses,” says the report from the study.

Public Health England reports, “The analysis included 14,019 cases of the Delta variant—166 of whom were hospitalised—between 12 April and 4 June, looking at emergency hospital admissions in England.”
