County physicians hope to clear the air on COVID-19 vaccine

Debate regarding safety and effectiveness of vaccines, and of the COVID-19 vaccine in particular, has prompted Prince Edward County Family Health Team (PEFHT) physicians to reach out to residents to speak to the development and effectiveness of the COVID-19 vaccines.

While COVID-19 cases remain low in the region (three cases as of Thursday) the PEFHT doctors say residents can be proud of the achievement, but remind that over the past few months the number of cases increased dramatically.

From the first reported infected patient on March 18, 2020, it took until Sept. 4, 2020 to record the region’s 50th case. There were 316 more cases in the four months since then.

“We all know the challenges of lockdowns, social distancing, inability to travel, wearing masks, etc., but relief is hopefully on the horizon in the form of COVID-19 vaccines,” said Dr. Don Koval, on behalf of the PEFHT family physicians, whom he notes have given many tens of thousands of various vaccines over the decades.

“We felt it our duty to share the facts about the COVID-19 vaccine with our patients and everyone else living in this area.”

He notes vaccinations have been around since the first Smallpox vaccine was developed in 1796.

“Since then, and during some of our lifetimes, we have:
• seen the worldwide eradication of Smallpox.
• seen the elimination of Polio from all but three countries in the world.
• seen huge drops in incidence of common but possibly fatal infections such as Influenza, Pneumonia, Diphtheria, Tetanus, Pertussis (whooping cough), Measles, Mumps, German measles, Meningitis, Epiglottitis, Chickenpox, Shingles, Hepatitis A & B, and others.
Due to vaccines, many doctors have never seen a case of some of these once common and often fatal diseases.”

Coronavirus, officially the SARS-CoV-2 virus, causes the infection known as COVID-19.

“Just over a year ago we began hearing reports of thousands of cases of this virus from Wuhan, China, with worrying news of its contagiousness and severity. As country after country experienced outbreaks of COVID-19 and scenes of packed intensive care units (ICUs) were shown on the news, a sense of dread came across many of us, especially those of us in health care. Knowing that even without a new, serious infectious disease to contend with, our hospitals and ICUs are often full to capacity. How were we going to cope with this anticipated onslaught?”

Most countries, including Canada, initially coped by shutting down all but essential services, cancelling all but emergency surgery and treatments.

“We started avoiding other people and began wearing masks in more and more situations. People waiting for elective surgery such as cataract surgery, joint replacements, etc. were put on indefinite hold.

“Cancer and cardiac surgeries were done in emergencies only, leaving patients with growing tumours or clogged arteries in their hearts hoping they would survive until the lockdown was over. Some did not.”

Koval notes the lockdown mostly worked, and Canada’s infection rates remained quite low.

“Unfortunately, many of our most vulnerable citizens in long-term care homes were infected and succumbed prior to the widespread lockdown. Who will ever forget the reports of the deaths of over half of the residents of the Pinecrest Nursing Home in Bobcaygeon, in March and April 2020?”

While infections in the GTA and other larger cities increased, in Hastings and Prince Edward counties and surrounding counties did well in comparison, with “just” 368 cases and five deaths so far.

Koval reminds that as soon as the world public health leaders became aware of the severity of the COVID-19 pandemic, unprecedented effort, resources, expertise, and money was poured into the development of multiple COVID-19 vaccination possibilities. Two of these vaccines are now approved in Canada and the US, and numerous others may soon become available.

Koval explains the vaccines currently approved in Canada – from the companies Pfizer-BioNTech and Moderna.

“The Pfizer-BioNTech and Moderna vaccines, like some others in development are messenger RNA vaccines, which contain snippets of genetic instructions that coax our immune cells to manufacture antibodies to the “spike” protein on the surface of the coronavirus to combat the virus and prevent COVID-19. These vaccines were developed, tested, and approved in less than a year after the virus was identified. Other virus vaccines have taken much longer, often up to 10 years.”

That, he notes, raises questions in many people’s minds:
• how did these vaccines get developed so quickly?
• how effective are they?
• how safe are they?
• how long does immunity last?

“Firstly, the world’s scientists were able to develop COVID-19 vaccines so quickly because of:
• decades of research on other strains of coronavirus prior to COVID-19, such as Middle East Respiratory Syndrome (MERS) and Sars-CoV (SARS).
• advances in science and technology.
• international collaboration among scientists, health professionals, researchers, industry, and governments.
• increased dedicated funding.

“Secondly, between them, the Pfizer-BioNTech and Moderna companies were able to recruit over 76,750 volunteers who had not previously contracted COVID-19 to enter randomized, double-blinded clinical trials of the effectiveness and safety of their vaccines. These are enormous numbers compared to most clinical trials, because large numbers of healthy people were anticipated to need vaccinating and because understanding effectiveness and safety were paramount.”

The trials were done between July 2020 and January 2021 by randomly dividing the volunteers into two very similar groups by gender, age, ethnicity, and medical conditions.

“Half of each group received two doses of the active vaccine and the other half received two doses of an identical looking placebo vaccine,” said Koval. “Then, the participants were observed for many months and tested for COVID-19 if they developed any symptoms. Finally, around the beginning of December 2020 the results were analyzed and published in major medical journals.”

Koval says the effectiveness of both vaccines was demonstrated by nearly identical results, with an almost 95 per cent reduction in the incidence of COVID-19 infections among the group who received the vaccine compared to the placebo recipients.

“Between the two studies, only 19 vaccinated patients were infected with COVID-19, compared to 347 people who received the placebo shot. More strikingly, while 39 of the placebo recipients developed a severe case of the infection requiring hospitalization, only one of the actual vaccine recipients developed severe disease. While there was only one death among the participants in both studies, it occurred in a person who received the placebo vaccine. These are very impressive results for any vaccination trial.”

Koval says the vaccines both seemed to be very safe.

“Safety has been maintained because before any vaccines are available in Ontario they must undergo rigorous clinical trials to ensure they are safe and effective and be evaluated and authorized for use by Health Canada using rigorous standards.

“While many people develop minor side effects after receiving the vaccine such as a sore arm, mild fever, aches and pains, and fatigue, these are felt to be signs that the immune system is being activated by the vaccine and are similar to what occurs with most vaccines. Severe reactions were rare (usually allergic reactions), similar in number to other vaccines, and were generally easily treatable.”

Koval says that at this point, experts don’t know how long the immunity triggered by the vaccine will last.

“But recent encouraging reports have been published showing that there are some recipients who were vaccinated over eight months ago who still have evidence of immunity to the COVID-19 virus.”

New, more contagious virus variants have developed and spread over the past few months that so far seem equally susceptible to the original vaccines.

“If the new strains are not susceptible, these vaccines can be readily adapted by the manufacturers to new mutations in the virus, which is a great asset in our battle against the pandemic.”

Prince Edward County Family Health Team doctors are universally recommending getting the COVID-19 vaccines (two doses, weeks apart) as soon as it becomes available.

In Hastings-Prince Edward the Public Health Unit is working on a plan to provide vaccination clinics to get vaccines into the arms of everyone who wants one, even if they don’t have a family physician or other primary care provider.

“Without mass vaccinations, it will probably take years for natural immunity to build up in the community and the ongoing infections and deaths will continue to put enormous pressure on our health care system.”

Currently, vaccines are in limited supply and are only being given to residents and staff of long-term care homes. Next, the plan will be to vaccinate front line health care workers and then move on to independently living seniors, and then to the general population as more of the vaccines are delivered.

“Since the harm caused by the virus is generally much worse in the older population, the plan is to go from oldest to youngest in prioritizing vaccinating everyone. Talk to your primary health care provider about whether you should get the Covid-19 vaccine before your turn (by age) comes up. ”

Koval notes that at this point, vaccines are not approved for people under the age of 16 years, but that may change with more research.

It is anticipated that by the end of this year enough of the vaccines will have been delivered to Canada to provide a vaccination to everyone who wants one. Both of the currently available vaccines will be used, and everyone should get two doses of the same vaccine a few weeks apart.

“Once we reach about 70-80 per cent of citizens who have developed immunity either by being infected with the virus or by getting immunized, then we will achieve herd immunity and COVID-19 will gradually disappear. Then, hopefully, life can return to normal. Unmasked social gatherings and travel can resume, and the risk of having our hospitals overwhelmed by sick patients will be much reduced.”

Koval, on behalf of the doctors of Prince Edward County, states almost everyone should get vaccinated “to protect themselves, and also as a civic duty to protect the most vulnerable in our society from this devastating infection.”

    I read with interest the article on vaccinations by Dr. Koval, written on behalf of the Prince Edward County Family Health Team. I did not find any statistics as to how many people actually decline the vaccination. But I do know that many people, including myself, are quite desperate to get the vaccination. Unfortunately we have no say in the matter. If and when we might have this choice of getting vaccinated or not, is anybody’s guess. The information on vaccine arrivals is quite confusing to say the least, – Canada might receive vaccines or it may not. Canada might have its own vaccine but, if so, it will most likely not be until 2022. Both governments, federal and provincial, have failed in their mandate to provide leadership and protect its citizens.

    Thank you Dr. Koval for your reassurances and thanks to all of our health care providers for your dedication. As a healthy, physically active person over 70 years of age, I hope to be around for another 20 plus years. As a result I will happily take the vaccine when it is made available to me. I have followed the health guidelines, distancing, hand washing, masking, avoiding travel and haven’t seen my kids and grandkids for over a year. It has not been easy but it beats the crap out of the alternative.
