New research sheds light on how Canadian researchers developed a key component of the mRNA COVID-19 vaccines but failed to share it with the world
Because COVID-19 is a relatively new virus, researchers still aren’t sure exactly how long vaccines and prior infections provide protection.
Vaccine passports can and have been used to increase surveillance by governments. Transparency and accountability are crucial for protecting the privacy of civilians.
Vaccine hesitancy is often met with one of two responses: Ridicule, or factual information. Both assume a failure of reason, but human behaviour is more complex than reason, so both responses fail.
Canada’s ‘us against them’ COVID-19 strategy is amplifying social division, creating major psychosocial impacts, and has resulted in a significant decrease in trust toward authorities.
Stories build powerful emotional attachments. We root for heroes, boo their opponents and get anxious for the fictional problem to be solved. Facts have very little to do with it.
After addressing the issue of vaccine supply, closing gaps in logistics performance is critical to changing the course of the pandemic in Africa.
Emerging evidence suggests the highly infectious Omicron variant has the ability to escape the protection two vaccine doses offer.
Instead of a self-serving, diesel-stinking, neighbourhood-clogging mob that negatively impacts the freedom of others, the convoy should consider going home and learning about different perspectives.
It’s too soon to recommend booster shots for younger children. But we can watch what’s happening in the US, where children as young as 12 are receiving theirs.
Most Canadians support government measures to help control the spread of COVID-19, according to a public opinion study. But they’re growing weary of the pandemic.
The arrival of the highly infectious Omicron variant has changed the COVID landscape in Australia. We asked 5 experts whether it’s time to rethink vaccine mandates for dining, fitness and events.
New Zealand’s system of managed quarantine at the border may soon be less important, but we could well need to stand it up again quickly if a new COVID-19 variant emerges.
GoFundMe claims it won’t fund campaigns that promote hate or misinformation. So why is it backing the so-called freedom convoy that’s currently causing so much incendiary disruption in Ottawa?
The antagonism driven by political interference in COVID-19 vaccination is fuelling hesitancy. Mass vaccination campaigns require public buy-in via trusted health-care providers and community leaders.
Studies suggest seniors without the booster shot run a higher risk of infection and hospitalization from the omicron variant.
Variant-specific vaccines would undoubtedly increase immunity. But waves of new variants would engulf the population faster than these vaccines could ever be deployed.
People are buzzing with questions about the omicron variant and whether it could help usher in herd immunity. A team of virologists deciphers the latest findings.
In a time-honoured tradition of Canadian democracy, government regulations become public when they appear in the Canada Gazette. That’s why Ottawa’s proposal to bypass that step is so troublesome.
