How long will the COVID-19 vaccine protect you? Here’s what we know so far – Global News

Published

 on


With COVID-19 vaccinations officially underway in Canada and other parts around the world, there appears to be a light at the end of the tunnel, even as coronavirus cases and deaths continue to rise.

A vaccine can prevent illness from the novel coronavirus, but as real-world vaccinations take place out of clinical trial settings, there are still some unanswered questions.

Coronavirus vaccines: What you should know about the side effects

“Should we expect the pandemic to be over once a vaccine is available for public use? Not exactly,” Julian Daniel Sunday Willett, a PhD student at McGill University, wrote in a recent column for Global News.

“A vaccine will not be perfect, and it takes time for the immune system to be ready to protect us.”

Here’s how it works:

A vaccine is generally made up of a weakened or a dead virus, which, once injected, prompts the body to fight off the invader and build immunity.

Both Pfizer and Moderna’s candidates have been manufactured using mRNA-based technology, a relatively new way to make vaccines.

Instead of injecting a deactivated form of the virus, the mRNA vaccine uses a component of the virus DNA called messenger RNA that basically contains the genetic instructions for the human body to make the specific spike protein of the coronavirus.

By doing this, the immune system learns to recognize and respond to that specific protein, meaning it can more quickly mount a response if the virus enters the body. The mRNA, however, does not modify a person’s DNA or genetic makeup.

“When your body actually sees the real virus, then you have the weapons already in place — the antibodies and the cells that know this virus that can recognize it — and can kill it faster,” Dr. Donald Vinh, an infectious disease specialist and a medical microbiologist at the McGill University Health Center, told Global News.

According to the data from the clinical trials, Pfizer’s vaccine, which is 95 per cent effective, can offer partial protection as early as 12 days after the first dose.

That protection can last for at least two months, according to Vinh. A second dose is then required to achieve the vaccine’s full potential.

The data also showed that a second dose given 21 days later boosted the immune response, offering protection starting one week after the second jab.

Moderna’s candidate, which is still pending approval by Health Canada, can mount protective antibody levels within two weeks of the first dose and last for at least three months, Vinh said.

The Moderna vaccine, which also requires a second shot, has shown to be 94 per cent effective.

However, it still remains to be seen what the long-term immune response will be after vaccination.

“We’ve only started using this particular product in humans since March when the Phase 1 clinical trials began, so we don’t actually know how long protection will last,” Dr. Isaac Bogoch, an infectious disease specialist at the University of Toronto, said during a media briefing on Zoom.

“And clearly, this is something that is going to be studied formally with time to see if perhaps people do need a booster vaccine.”

How Canada’s COVID-19 vaccine rollout plan is unfolding

While more research is required, Dr. Supriya Sharma, Health Canada’s chief medical adviser, said in a press conference last week that there are promising early findings in this area.

“I have to say so far, from the data, it does look like that immunity is continuing. And certainly from some of the earlier animal data in the pre-clinical trials, it looks like it is conferring longer-range immunity. But that’s something that’s an ongoing question.”

Can a vaccine prevent the spread of coronavirus?

Vaccines are typically designed to prevent people from getting sick with the virus, but it is not yet clear if the COVID-19 vaccines by Pfizer or Moderna can stop you from transmitting the virus to others.

This is why is it important for people to continue taking precautions — physical distancing, wearing masks and avoiding gatherings, especially in poorly-ventilated spaces — until the vaccine is rolled out on a large enough scale so that we know its impact on both infection and transmission, Vinh said.

As experience with past vaccinations have shown, he added, the more people are immunized, the better the chances of reaching herd immunity

According to the World Health Organization (WHO), herd immunity is when a population can be protected from a certain virus, like COVID-19, if a threshold of vaccination is reached. It’s achieved by protecting people from a virus, not by exposing them to it, the WHO said.

“What we’ve seen with the rollout of the flu vaccines for the last several decades is that it also decreases transmission in the community so that even people who cannot get vaccinated… they can still be protected because other people in the community are vaccinated,” Vinh said.

When are we safe?

Experts suggest at least 70 to 75 per cent of the population will have to be immunized to control the spread of the virus.

“The effectiveness of these vaccines are only going to be as good as the number of people who get them,” Vinh said.

In the early stages, Canada, like the U.S., is focusing on high-risk groups, including long-term care workers and residents, those aged above 80, front-line health care workers, and Indigenous community members.

Dr. Anna Banerji, an infectious disease specialist at the University of Toronto, said this prioritization can help in a significant drop in the number of hospitalizations and deaths.

“What we need is for most of the people to get vaccinated so that the outbreak goes down and we get herd immunity,” she told Global News.

“You want to first vaccinate the people at highest risk of severe disease or death.”

The #1 Skill I Look For When Hiring

Published

 on

File this column under “for what it’s worth.”

“Communication is one of the most important skills you require for a successful life.” — Catherine Pulsifer, author.

I’m one hundred percent in agreement with Pulsifer, which is why my evaluation of candidates begins with their writing skills. If a candidate’s writing skills and verbal communication skills, which I’ll assess when interviewing, aren’t well above average, I’ll pass on them regardless of their skills and experience.

 

Why?

 

Because business is fundamentally about getting other people to do things—getting employees to be productive, getting customers to buy your products or services, and getting vendors to agree to a counteroffer price. In business, as in life in general, you can’t make anything happen without effective communication; this is especially true when job searching when your writing is often an employer’s first impression of you.

 

Think of all the writing you engage in during a job search (resumes, cover letters, emails, texts) and all your other writing (LinkedIn profile, as well as posts and comments, blogs, articles, tweets, etc.) employers will read when they Google you to determine if you’re interview-worthy.

 

With so much of our communication today taking place via writing (email, text, collaboration platforms such as Microsoft Teams, Slack, ClickUp, WhatsApp and Rocket.Chat), the importance of proficient writing skills can’t be overstated.

 

When assessing a candidate’s writing skills, you probably think I’m looking for grammar and spelling errors. Although error-free writing is important—it shows professionalism and attention to detail—it’s not the primary reason I look at a candidate’s writing skills.

 

The way someone writes reveals how they think.

 

  • Clear writing = Clear thinking
  • Structured paragraphs = Structured mind
  • Impactful sentences = Impactful ideas

 

Effective writing isn’t about using sophisticated vocabulary. Hemingway demonstrated that deceptively simple, stripped-down prose can captivate readers. Effective writing takes intricate thoughts and presents them in a way that makes the reader think, “Damn! Why didn’t I see it that way?” A good writer is a dead giveaway for a good thinker. More than ever, the business world needs “good thinkers.”

 

Therefore, when I come across a candidate who’s a good writer, hence a good thinker, I know they’re likely to be able to write:

 

  • Emails that don’t get deleted immediately and are responded to
  • Simple, concise, and unambiguous instructions
  • Pitches that are likely to get read
  • Social media content that stops thumbs
  • Human-sounding website copy
  • Persuasively, while attuned to the reader’s possible sensitivities

 

Now, let’s talk about the elephant in the room: AI, which job seekers are using en masse. Earlier this year, I wrote that AI’s ability to hyper-increase an employee’s productivity—AI is still in its infancy; we’ve seen nothing yet—in certain professions, such as writing, sales and marketing, computer programming, office and admin, and customer service, makes it a “fewer employees needed” tool, which understandably greatly appeals to employers. In my opinion, the recent layoffs aren’t related to the economy; they’re due to employers adopting AI. Additionally, companies are trying to balance investing in AI with cost-cutting measures. CEOs who’ve previously said, “Our people are everything,” have arguably created today’s job market by obsessively focusing on AI to gain competitive advantages and reduce their largest expense, their payroll.

 

It wouldn’t be a stretch to assume that most AI usage involves generating written content, content that’s obvious to me, and likely to you as well, to have been written by AI. However, here’s the twist: I don’t particularly care.

 

Why?

 

Because the fundamental skill I’m looking for is the ability to organize thoughts and communicate effectively. What I care about is whether the candidate can take AI-generated content and transform it into something uniquely valuable. If they can, they’re demonstrating the skills of being a good thinker and communicator. It’s like being a great DJ; anyone can push play, but it takes skill to read a room and mix music that gets people pumped.

 

Using AI requires prompting effectively, which requires good writing skills to write clear and precise instructions that guide the AI to produce desired outcomes. Prompting AI effectively requires understanding structure, flow and impact. You need to know how to shape raw information, such as milestones throughout your career when you achieved quantitative results, into a compelling narrative.

So, what’s the best way to gain and enhance your writing skills? As with any skill, you’ve got to work at it.

Two rules guide my writing:

 

  • Use strong verbs and nouns instead of relying on adverbs, such as “She dashed to the store.” instead of “She ran quickly to the store.” or “He whispered to the child.” instead of “He spoke softly to the child.”
  • Avoid using long words when a shorter one will do, such as “use” instead of “utilize” or “ask” instead of “inquire.” As attention spans get shorter, I aim for clarity, simplicity and, most importantly, brevity in my writing.

 

Don’t just string words together; learn to organize your thoughts, think critically, and communicate clearly. Solid writing skills will significantly set you apart from your competition, giving you an advantage in your job search and career.

Politics likely pushed Air Canada toward deal with ‘unheard of’ gains for pilots

Published

 on

 

MONTREAL – Politics, public opinion and salary hikes south of the border helped push Air Canada toward a deal that secures major pay gains for pilots, experts say.

Hammered out over the weekend, the would-be agreement includes a cumulative wage hike of nearly 42 per cent over four years — an enormous bump by historical standards — according to one source who was not authorized to speak publicly on the matter. The previous 10-year contract granted increases of just two per cent annually.

The federal government’s stated unwillingness to step in paved the way for a deal, noted John Gradek, after Prime Minister Justin Trudeau made it plain the two sides should hash one out themselves.

“Public opinion basically pressed the federal cabinet, including the prime minister, to keep their hands clear of negotiations and looking at imposing a settlement,” said Gradek, who teaches aviation management at McGill University.

After late-night talks at a hotel near Toronto’s Pearson airport, the country’s biggest airline and the union representing 5,200-plus aviators announced early Sunday morning they had reached a tentative agreement, averting a strike that would have grounded flights and affected some 110,000 passengers daily.

The relative precariousness of the Liberal minority government as well as a push to appear more pro-labour underlay the prime minister’s hands-off approach to the negotiations.

Trudeau said Friday the government would not step in to fix the impasse — unlike during a massive railway work stoppage last month and a strike by WestJet mechanics over the Canada Day long weekend that workers claimed road roughshod over their constitutional right to collective bargaining. Trudeau said the government respects the right to strike and would only intervene if it became apparent no negotiated deal was possible.

“They felt that they really didn’t want to try for a third attempt at intervention and basically said, ‘Let’s let the airline decide how they want to deal with this one,'” said Gradek.

“Air Canada ran out of support as the week wore on, and by the time they got to Friday night, Saturday morning, there was nothing left for them to do but to basically try to get a deal set up and accepted by ALPA (Air Line Pilots Association).”

Trudeau’s government was also unlikely to consider back-to-work legislation after the NDP tore up its agreement to support the Liberal minority in Parliament, Gradek said. Conservative Leader Pierre Poilievre, whose party has traditionally toed a more pro-business line, also said last week that Tories “stand with the pilots” and swore off “pre-empting” the negotiations.

Air Canada CEO Michael Rousseau had asked Ottawa on Thursday to impose binding arbitration pre-emptively — “before any travel disruption starts” — if talks failed. Backed by business leaders, he’d hoped for an effective repeat of the Conservatives’ move to head off a strike in 2012 by legislating Air Canada pilots and ground crew to stick to their posts before any work stoppage could start.

The request may have fallen flat, however. Gradek said he believes there was less anxiety over the fallout from an airline strike than from the countrywide railway shutdown.

He also speculated that public frustration over thousands of cancelled flights would have flowed toward Air Canada rather than Ottawa, prompting the carrier to concede to a deal yielding “unheard of” gains for employees.

“It really was a total collapse of the Air Canada bargaining position,” he said.

Pilots are slated to vote in the coming weeks on the four-year contract.

Last year, pilots at Delta Air Lines, United Airlines and American Airlines secured agreements that included four-year pay boosts ranging from 34 per cent to 40 per cent, ramping up pressure on other carriers to raise wages.

After more than a year of bargaining, Air Canada put forward an offer in August centred around a 30 per cent wage hike over four years.

But the final deal, should union members approve it, grants a 26 per cent increase in the first year alone, retroactive to September 2023, according to the source. Three wage bumps of four per cent would follow in 2024 through 2026.

Passengers may wind up shouldering some of that financial load, one expert noted.

“At the end of the day, it’s all us consumers who are paying,” said Barry Prentice, who heads the University of Manitoba’s transport institute.

Higher fares may be mitigated by the persistence of budget carrier Flair Airlines and the rapid expansion of Porter Airlines — a growing Air Canada rival — as well as waning demand for leisure trips. Corporate travel also remains below pre-COVID-19 levels.

Air Canada said Sunday the tentative contract “recognizes the contributions and professionalism of Air Canada’s pilot group, while providing a framework for the future growth of the airline.”

The union issued a statement saying that, if ratified, the agreement will generate about $1.9 billion of additional value for Air Canada pilots over the course of the deal.

Meanwhile, labour tension with cabin crew looms on the horizon. Air Canada is poised to kick off negotiations with the union representing more than 10,000 flight attendants this year before the contract expires on March 31.

Federal $500M bailout for Muskrat Falls power delays to keep N.S. rate hikes in check

Published

 on

 

HALIFAX – Ottawa is negotiating a $500-million bailout for Nova Scotia’s privately owned electric utility, saying the money will be used to prevent a big spike in electricity rates.

Federal Natural Resources Minister Jonathan Wilkinson made the announcement today in Halifax, saying Nova Scotia Power Inc. needs the money to cover higher costs resulting from the delayed delivery of electricity from the Muskrat Falls hydroelectric plant in Labrador.

Wilkinson says that without the money, the subsidiary of Emera Inc. would have had to increase rates by 19 per cent over “the short term.”

Nova Scotia Power CEO Peter Gregg says the deal, once approved by the province’s energy regulator, will keep rate increases limited “to be around the rate of inflation,” as costs are spread over a number of years.

The utility helped pay for construction of an underwater transmission link between Newfoundland and Nova Scotia, but the Muskrat Falls project has not been consistent in delivering electricity over the past five years.

Those delays forced Nova Scotia Power to spend more on generating its own electricity.
