Kingston, Ont., area health officials examining future of local vaccination efforts – Global News
More than 455,000 people in the Kingston region have been vaccinated against COVID-19.
Now health officials say they’re using the summer months, with low infection rates, to look ahead to what fall might bring, urging those who are still eligible to get vaccinated do so.
“Large, mass immunization clinics, mobile clinics, drive-thru clinics and small primary care clinics doing their own vaccine,” said Brian Larkin with KFL&A Public Health.
Infectious disease expert Dr. Gerald Evans says those who are still eligible for a third and fourth dose should take advantage and roll up their sleeves during the low-infection summer months.
“Now in 2022, although you still might get COVID, you’re probably not going to be very sick. You are less likely to transmit and ultimately that’s one of the ways we’re going to control the pandemic,” added Evans.
He expects another wave of COVID-19 to hit in late October to early November and that a booster may be made available for those younger than 60 who still aren’t eligible for a fourth dose.
“The best case scenario is a few more years of watching rises in cases, getting boosters to control things and ultimately getting out of it with this being just another coronavirus that just tends to cause a respiratory infection and worst-case scenario is a new variant where all the potential possibilities exist to have a big surge in cases and hopefully not a lot more serious illness,” said Evans.
Public Health says they’re still waiting for direction from the province on what’s to come this fall.
“We’re expecting that we would see more age groups and younger age groups be eligible for more doses or boosters but about when those ages start, we have yet to have that confirmed,” said Larkin.
The last 18 months of vaccines paving the way for the new normal could mean a yearly COVID booster alongside the annual flu shot.

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

Quebec successfully pushes back against rise in measles cases – CBC.ca
Quebec appears to be winning its battle against the rising tide of measles after 45 cases were confirmed province-wide this year.
“We’ve had no locally transmitted measles cases since March 25, so that’s good news,” said Dr. Paul Le Guerrier, responsible for immunization for Montreal Public Health.
There are 17 patients with measles in Quebec currently, and the most recent case is somebody who was infected while abroad, he said.
But it was no small task to get to this point.
Le Guerrier said once local transmission was detected, news was spread fast among health centres to ensure proper protocols were followed — such as not letting potentially infected people sit in waiting rooms for hours on end.
Then about 90 staffers were put to work, tracking down those who were in contact with positive cases and are not properly vaccinated. They were given post-exposure prophylaxis, which prevents disease, said Le Guerrier.
From there, a vaccination campaign was launched, especially in daycares, schools and neighbourhoods with low inoculation rates. There was an effort to convince parents to get their children vaccinated.
Vaccination in schools boosted
Some schools, mostly in Montreal, had vaccination rates as low as 30 or 40 per cent.
“Vaccination was well accepted and parents responded well,” said Le Guerrier. “Some schools went from very low to as high as 85 to 90 per cent vaccination coverage.”
But it’s not only children who aren’t properly vaccinated. Le Guerrier said people need two doses after age one to be fully inoculated, and he encouraged people to check their status.
There are all kinds of reasons why people aren’t vaccinated, but it’s only about five per cent who are against immunization, he said. So far, some 10,000 people have been vaccinated against measles province-wide during this campaign, Le Guerrier said.
The next step is to continue pushing for further vaccination, but he said, small outbreaks are likely in the future as measles is spreading abroad and travellers are likely to bring it back with them.
Need to improve vaccination rate, expert says
Dr. Donald Vinh, an infectious diseases specialist from the McGill University Health Centre, said it’s not time to rest on our laurels, but this is a good indication that public health is able to take action quickly and that people are willing to listen to health recommendations.
“We are not seeing new cases or at least the new cases are not exceeding the number of cases that we can handle,” said Vinh.
“So these are all reassuring signs, but I don’t think it’s a sign that we need to become complacent.”
Vinh said there are also signs that the public is lagging in vaccine coverage and it’s important to respond to this with improved education and access. Otherwise, microbes capitalize on our weaknesses, he said.
Getting vaccination coverage up to an adequate level is necessary, Vinh said, or more small outbreaks like this will continue to happen.
“And it’s very possible that we may not be able to get one under control if we don’t react quickly enough,” he said.

Pregnant women in the Black Country urged to get whooping cough vaccine – BBC.com
Pregnant women urged to get whooping cough vaccine
Pregnant women in the Black Country are being urged to get vaccinated against whooping cough after a rise in cases.
The bacterial infection of the lungs spreads very easily and can cause serious problems, especially in babies and young children.
The Black Country Integrated Care Board (ICB) is advising pregnant women between 16 and 32 weeks to contact their GP to get the vaccine so their baby has protection from birth.
The UK Health Security Agency warned earlier this year of a steady decline in uptake of the vaccine in pregnant women and children.
Symptoms of the infection, also known as “100-day cough”, are similar to a cold, with a runny nose and sore throat.
Sally Roberts, chief nursing officer for the ICB, which covers Wolverhampton, Dudley, Walsall and Sandwell, said anyone could catch it, but it was more serious for young children and babies.
“Getting vaccinated while you’re pregnant is highly effective in protecting your baby from developing whooping cough in the first few weeks of their life – ideally from 16 weeks up to 32 weeks of pregnancy,” she said.
“If for any reason you miss having the vaccine, you can still have it up until you go into labour.”
