For Canadians anxiously craving an inoculation against the coronavirus, this week brought both optimism and words of sobering caution.
The federal government on Wednesday announced the first of many major deals to buy vaccines from two U.S.-based multinational drug companies: Pfizer and Moderna.
There will be “millions” of doses, Anita Anand, the cabinet minister responsible for the deal, said at a news conference. She did not offer any more details. But she and another cabinet minister said the government was negotiating deals with other vaccine makers, including some in Canada.
The catch in all of this is that neither Pfizer nor Moderna, nor anyone else, actually has a proven vaccine. The situation is similar to what happened with the Salk polio vaccine in the mid-1950s. As I wrote in last week’s newsletter, to speed up that vaccine, the federal government gambled and placed a bulk order to start production at Connaught Laboratories before trials on patients had proved that it was safe and effective.
Connaught, which played a crucial role in bringing the Salk vaccine to production, was the only game in Canada back then. This time around, many more companies are vying to make the coronavirus vaccine. The World Health Organization counts 28 possible vaccines now undergoing trials. Many more, including some Canadian candidates, are in earlier phases.
To guide its vaccine shopping, as well as its investments in Canadian vaccines and vaccine production, the federal government has turned to a panel of experts with backgrounds in science, medicine, public health and vaccine manufacturing.
As bets go, choosing Pfizer and Moderna is relatively conservative. Late last month, both companies began the first large-scale trials of their candidate vaccines in the United States.
Assuming all goes well, Ms. Anand said, the first deliveries should appear next year.
But earlier in the week, Dr. Theresa Tam, Canada’s chief public health officer, warned against making too many assumptions about the power of vaccination to end the current pandemic.
At this stage, she said, vaccines are not “the silver bullet solution.”
She said many vaccines for other viruses only lessen the consequences of infection; they don’t prevent it.
As a result, she said, public health officials are working on the assumption that many of the measures now in place will be around for upward of two years.
Reggie Lo, a professor emeritus at the University of Guelph who focuses on vaccine development, told me this week that the first vaccine candidates, which may not be the most effective ones, may appear by the end of the year, but scaling up their production to inoculate billions will be a formidable challenge.
He also stressed that with the exception of smallpox, other deadly viruses have not been wiped out by decades of vaccination.
“The public needs to deal with this ‘forever,’” Dr. Lo said in an email. “Anyone who thinks the epidemic is over with development of a vaccine failed to grasp the enormity of the problem.”
Last week’s newsletter prompted the former Prime Minister Paul Martin to call me. His father, also Paul Martin, was, as federal health minister, the main player in Canada’s rollout and participation in development of the Salk vaccine.
The younger Mr. Martin, who was infected with polio as a child, had a memory of that time that captures the uncertainty around vaccines.

Frequently Asked Questions
Updated August 6, 2020
- Think about a bar. Alcohol is flowing. It can be loud, but it’s definitely intimate, and you often need to lean in close to hear your friend. And strangers have way, way fewer reservations about coming up to people in a bar. That’s sort of the point of a bar. Feeling good and close to strangers. It’s no surprise, then, that bars have been linked to outbreaks in several states. Louisiana health officials have tied at least 100 coronavirus cases to bars in the Tigerland nightlife district in Baton Rouge. Minnesota has traced 328 recent cases to bars across the state. In Idaho, health officials shut down bars in Ada County after reporting clusters of infections among young adults who had visited several bars in downtown Boise. Governors in California, Texas and Arizona, where coronavirus cases are soaring, have ordered hundreds of newly reopened bars to shut down. Less than two weeks after Colorado’s bars reopened at limited capacity, Gov. Jared Polis ordered them to close.
I have antibodies. Am I now immune?
- As of right now, that seems likely, for at least several months. There have been frightening accounts of people suffering what seems to be a second bout of Covid-19. But experts say these patients may have a drawn-out course of infection, with the virus taking a slow toll weeks to months after initial exposure. People infected with the coronavirus typically produce immune molecules called antibodies, which are protective proteins made in response to an infection. These antibodies may last in the body only two to three months, which may seem worrisome, but that’s perfectly normal after an acute infection subsides, said Dr. Michael Mina, an immunologist at Harvard University. It may be possible to get the coronavirus again, but it’s highly unlikely that it would be possible in a short window of time from initial infection or make people sicker the second time.
I’m a small-business owner. Can I get relief?
- The stimulus bills enacted in March offer help for the millions of American small businesses. Those eligible for aid are businesses and nonprofit organizations with fewer than 500 workers, including sole proprietorships, independent contractors and freelancers. Some larger companies in some industries are also eligible. The help being offered, which is being managed by the Small Business Administration, includes the Paycheck Protection Program and the Economic Injury Disaster Loan program. But lots of folks have not yet seen payouts. Even those who have received help are confused: The rules are draconian, and some are stuck sitting on money they don’t know how to use. Many small-business owners are getting less than they expected or not hearing anything at all.
What are my rights if I am worried about going back to work?
What is school going to look like in September?
- It is unlikely that many schools will return to a normal schedule this fall, requiring the grind of online learning, makeshift child care and stunted workdays to continue. California’s two largest public school districts — Los Angeles and San Diego — said on July 13, that instruction will be remote-only in the fall, citing concerns that surging coronavirus infections in their areas pose too dire a risk for students and teachers. Together, the two districts enroll some 825,000 students. They are the largest in the country so far to abandon plans for even a partial physical return to classrooms when they reopen in August. For other districts, the solution won’t be an all-or-nothing approach. Many systems, including the nation’s largest, New York City, are devising hybrid plans that involve spending some days in classrooms and other days online. There’s no national policy on this yet, so check with your municipal school system regularly to see what is happening in your community.
His father, he said, was usually good spirited at home. But one afternoon in 1955 when Mr. Martin went into his library, his father was unusually distracted and testy. He was told to leave and go see his mother.
From her, Mr. Martin learned that his father was grappling with perhaps the most difficult decision of his life: whether to continue with plans to vaccinate Canada. A batch of vaccines made by Cutter Laboratories, an American company, had been determined to be defective and ended up infecting 40,000 children. About 200 of them were left paralyzed, and 10 died.
As a result, the United States suspended polio vaccination for several months, a decision that led to infections, deaths and paralysis. Ultimately, the elder Mr. Martin was convinced that Connaught’s vaccine was safe, and Canada continued its inoculations without incident.
The stakes, if anything, are greater now as the world rushes to produce a coronavirus vaccine. We all may be called to have patience and realistic expectations.
