Trudeau says Pfizer vaccine could be 'light at the end of the tunnel,' but hurdles remain – Sarnia and Lambton County This Week

Canada bought access to 20 million doses of Pfizer’s vaccine, because the vaccine requires two doses to be effective, the early supply will be enough to inoculate roughly 10 million people

OTTAWA — Prime Minister Justin Trudeau described promising vaccine results as a potential “light at the end of the tunnel,” Monday, but he also urged caution, because there are still several hurdles to mount before the vaccine is widely available.

Pharmaceutical giant Pfizer announced Monday the vaccine it was developing with BioNTech was showing strong results. In addition to being safe, the vaccine was proving to be more than 90 per cent effective in preventing people from getting sick with the virus.

The data has yet to be independently verified, but the trial included a total of 43,538 people across multiple countries and from a wide range of ethnicities.

Trudeau said the news was encouraging, but said Canadians can’t ease up yet and still have to limit their social contacts, wear a mask when social distancing isn’t impossible and take other steps to reduce spread of the virus.

“We hope to see vaccines landing in the early next year, but between now and then it is really important that we double down on our efforts,” he said. “We need to do our part. We need to stay strong and hang in there a few more months.”

He stressed the early results from the vaccine are positive, but until it is administered it can’t help people.

“If you catch COVID in the coming days or weeks a vaccine won’t help you.”

Dr. Zain Chagla, a professor of medicine at McMaster University and expert in infectious diseases said society will still have to wait for the peer-review of the company’s research and for more safety data, but if that holds up this could be the beginning of the end of the pandemic.

“If this is the real deal signal, this is one good tool in the chest, and definitely something that starts the light at the end of the tunnel,” he said.

Canada bought access to 20 million doses of Pfizer’s vaccine, because the vaccine requires two doses to be effective, the early supply will be enough to inoculate roughly 10 million people, about a quarter of Canada’s 38 million people. When it announced the initial purchase in August, the government said it would be pursuing options to buy more than the initial 20 million, but those deals have not yet materialized.

The U.S. has ordered 100 million initial doses with options for another 500 million doses from the company as part of its large vaccine purchase. The company has said it can produce 50 million doses in 2020 and another 1.3 billion in 2021.

Canada has bought access to several vaccines and Trudeau said part of their strategy has always been to look for multiple options.

“Canada is one of the countries around the world with the very best portfolio of potential vaccines because we know that there is a certain amount of uncertainty as to which vaccines will land first,” he said.

Chagla said even if the other vaccine candidates aren’t successful, the 10 million doses from Pfizer would be a good start.

“There’s definitely a lot you could do with 10 million doses, even if it’s only a quarter of the population,” he said. “You can definitely at least reduce the risk of hospitalization and death for the most vulnerable. You can protect the people taking care of them and then you can try to make a dent in community transmission.”

Abacus Data released new polling on Monday as well, showing that hesitancy will be another one of the challenges for a vaccine roll out.

The firm surveyed 1,500 Canadians and found 33 per cent were eager to take a vaccine, while 42 per cent would do so eventually, but wanted to wait. A further 14 per cent say they would have to be convinced and 11 per cent say they won’t take the shot under any circumstances.

The vaccine news is coming as COVID-19 cases continue to surge across the country, with high case counts in Ontario, British Columbia, Alberta and Quebec. Hospitals in some parts of the country are starting to feel strained and deaths are continuing to mount.

Pfizer’s vaccine candidate is one of three that have already started providing evidence to Health Canada as part of the regulatory process. In a press release, the company said they hoped to have more data in late November and could submit information to regulators in the U.S. then.

The company’s vaccine has to be kept at temperatures below – 80 degrees Celsius and that will add to the complexity of its rollout should it be successful. The government has a tender underway for a logistics firm to manage the delivery and storage of vaccines.

Pfizer is set to handle delivery to provinces and territories in Canada, but the government is looking for a company to deliver large quantities of dry ice in order to keep the vaccines cold.

Chagla said that is one of the vaccine’s challenges.

“It’s not going to be an easy vaccine to roll out in pharmacies or family doctors’ offices,” he said.

All of the other potential candidates Canada has invested in have to be kept frozen or cool, but not at such low temperatures and they could be stored in commercial refrigerators and freezers.

Chagla said he hopes to see more progress on the other vaccine candidates in time, because the Pfizer vaccine will be especially difficult to roll out in the developing world.

Cancer Awareness Month

Posted on: Apr 18, 2024

April is Cancer Awareness Month

As we recognize Cancer Awareness Month, we stand together to raise awareness, support those affected, advocate for prevention, early detection, and continued research towards a cure. Cancer is the leading cause of death for Métis women and the second leading cause of death for Métis men. The Otipemisiwak Métis Government of the Métis Nation Within Alberta is working hard to ensure that available supports for Métis Citizens battling cancer are culturally appropriate, comprehensive, and accessible by Métis Albertans at all stages of their cancer journey.

300x250x1

Receiving a cancer diagnosis, whether for yourself or a loved one, can feel overwhelming, leaving you unsure of where to turn for support. In June, our government will be launching the Cancer Supports and Navigation Program which will further support Métis Albertans and their families experiencing cancer by connecting them to OMG-specific cancer resources, external resources, and providing navigation support through the health care system. This program will also include Métis-specific peer support groups for those affected by cancer.

With funding from the Canadian Partnership Against Cancer (CPAC) we have also developed the Métis Cancer Care Course to ensure that Métis Albertans have access to culturally safe and appropriate cancer services. This course is available to cancer care professionals across the country and provides an overview of who Métis people are, our culture, our approaches to health and wellbeing, our experiences with cancer care, and our cancer journey.

Together, we can make a difference in the fight against cancer and ensure equitable access to culturally safe and appropriate care for all Métis Albertans. Please click on the links below to learn more about the supports available for Métis Albertans, including our Compassionate Care: Cancer Transportation program.

I wish you all good health and happiness!

Type 2 diabetes is not one-size-fits-all: Subtypes affect complications and treatment options – The Conversation

Published

 on


You may have heard of Ozempic, the “miracle drug” for weight loss, but did you know that it was actually designed as a new treatment to manage diabetes? In Canada, diabetes affects approximately 10 per cent of the general population. Of those cases, 90 per cent have Type 2 diabetes.

This metabolic disorder is characterized by persistent high blood sugar levels, which can be accompanied by secondary health challenges, including a higher risk of stroke and kidney disease.

Locks and keys

In Type 2 diabetes, the body struggles to maintain blood sugar levels in an acceptable range. Every cell in the body needs sugar as an energy source, but too much sugar can be toxic to cells. This equilibrium needs to be tightly controlled and is regulated by a lock and key system.

300x250x1

In the body’s attempt to manage blood sugar levels and ensure that cells receive the right amount of energy, the pancreatic hormone, insulin, functions like a key. Cells cover themselves with locks that respond perfectly to insulin keys to facilitate the entry of sugar into cells.

Unfortunately, this lock and key system doesn’t always perform as expected. The body can encounter difficulties producing an adequate number of insulin keys, and/or the locks can become stubborn and unresponsive to insulin.

All forms of diabetes share the challenge of high blood sugar levels; however, diabetes is not a singular condition; it exists as a spectrum. Although diabetes is broadly categorized into two main types, Type 1 and Type 2, each presents a diversity of subtypes, especially Type 2 diabetes.

These subtypes carry their own characteristics and risks, and do not respond uniformly to the same treatments.

To better serve people living with Type 2 diabetes, and to move away from a “one size fits all” approach, it is beneficial to understand which subtype of Type 2 diabetes a person lives with. When someone needs a blood transfusion, the medical team needs to know the patient’s blood type. It should be the same for diabetes so a tailored and effective game plan can be implemented.

This article explores four unique subtypes of Type 2 diabetes, shedding light on their causes, complications and some of their specific treatment avenues.

Severe insulin-deficient diabetes: We’re missing keys!

In severe insulin-deficient diabetes, beta cells limit production of the keys that unlock cells to allow entry of sugar from the blood.

Insulin is produced by beta cells, which are found in the pancreas. In the severe insulin-deficient diabetes (SIDD) subtype, the key factories — the beta cells — are on strike. Ultimately, there are fewer keys in the body to unlock the cells and allow entry of sugar from the blood.

SIDD primarily affects younger, leaner individuals, and unfortunately, increases the risk of eye disease and blindness, among other complications. Why the beta cells go on strike remains largely unknown, but since there is an insulin deficiency, treatment often involves insulin injections.

Severe insulin-resistant diabetes: But it’s always locked!

In severe insulin-resistant diabetes, the locks start ignoring the keys, triggering the beta cells to produce even more keys to compensate.

In the severe insulin-resistant diabetes (SIRD) subtype, the locks are overstimulated and start ignoring the keys. As a result, the beta cells produce even more keys to compensate. This can be measured as high levels of insulin in the blood, also known as hyperinsulinemia.

This resistance to insulin is particularly prominent in individuals with higher body weight. Patients with SIRD have an increased risk of complications such as fatty liver disease. There are many treatment avenues for these patients but no consensus about the optimal approach; patients often require high doses of insulin.

Mild obesity-related diabetes: The locks are sticky!

Mild obesity-related (MOD) diabetes represents a nuanced aspect of Type 2 diabetes, often observed in individuals with higher body weight. Unlike more severe subtypes, MOD is characterized by a more measured response to insulin. The locks are “sticky,” so it is challenging for the key to click in place and open the lock. While MOD is connected to body weight, the comparatively less severe nature of MOD distinguishes it from other diabetes subtypes.

To minimize complications, treatment should include maintaining a healthy diet, managing body weight, and incorporating as much aerobic exercise as possible. This is where drugs like Ozempic can be prescribed to control the evolution of the disease, in part by managing body weight.

Mild age-related diabetes: I’m tired of controlling blood sugar!

Illustration of a lock and a beta cell

In people with mild age-related diabetes, both the locks and the beta cells that produce keys are tired, resulting in fewer keys and stubborn locks.
(Lili Grieco-St-Pierre, Jennifer Bruin/Created with BioRender.com)

Mild age-related diabetes (MARD) happens more often in older people and typically starts later in life. With time, the key factory is not as productive, and the locks become stubborn. People with MARD find it tricky to manage their blood sugar, but it usually doesn’t lead to severe complications.

Among the different subtypes of diabetes, MARD is the most common.

Unique locks, varied keys

While efforts have been made to classify diabetes subtypes, new subtypes are still being identified, making proper clinical assessment and treatment plans challenging.

In Canada, unique cases of Type 2 diabetes were identified in Indigenous children from Northern Manitoba and Northwestern Ontario by Dr. Heather Dean and colleagues in the 1980s and 90s. Despite initial skepticism from the scientific community, which typically associated Type 2 diabetes with adults rather than children, clinical teams persisted in identifying this as a distinct subtype of Type 2 diabetes, called childhood-onset Type 2 diabetes.

Indigenous community research partnerships can help address health inequities


Childhood-onset Type 2 diabetes is on the rise across Canada, but disproportionately affects Indigenous youth. It is undoubtedly linked to the intergenerational trauma associated with colonization in these communities. While many factors are likely involved, recent studies have discovered that exposure of a fetus to Type 2 diabetes during pregnancy increases the risk that the baby will develop diabetes later in life.

Acknowledging this distinct subtype of Type 2 diabetes in First Nations communities has led to the implementation of a community-based health action plan aimed at addressing the unique challenges faced by Indigenous Peoples. It is hoped that partnered research between communities and researchers will continue to help us understand childhood-onset Type 2 diabetes and how to effectively prevent and treat it.

A mosaic of conditions

Type 2 diabetes is not uniform; it’s a mosaic of conditions, each with its own characteristics. Since diabetes presents so uniquely in every patient, even categorizing into subtypes does not guarantee how the disease will evolve. However, understanding these subtypes is a good starting point to help doctors create personalized plans for people living with the condition.

While Indigenous communities, lower-income households and individuals living with obesity already face a higher risk of developing Type 2 diabetes than the general population, tailored solutions may offer hope for better management. This emphasizes the urgent need for more precise assessments of diabetes subtypes to help customize therapeutic strategies and management strategies. This will improve care for all patients, including those from vulnerable and understudied populations.
