An effective nasal vaccine could stop the virus that causes COVID-19 right at its point of entry. But devising one that works has been a challenge for researchers.
Systemic social issues affect vaccine access and acceptability. Yet, the term ‘vaccine hesitancy’ overlooks this, reducing the multiple factors that affect vaccine uptake to individual-level choices.
Nurses who identify as Democrats have a significantly higher likelihood of having their children vaccinated against COVID-19 than those who identify as Republicans.
Respiratory viruses are hitting young children and infants particularly hard this fall and winter season, and experts don’t yet know exactly why.
Flu and COVID-19 are expected to make headway during the current respiratory virus season. The best way to stay healthy is vaccination in conjunction with personal protective measures.
Researchers identified a connection between low levels of media literacy and COVID-19 vaccine hesitancy in people who consume their news via social media.
Adding COVID-19 to a list of ‘designated diseases’ will not make vaccination mandatory for school entry. But it may help increase COVID-19 vaccine uptake among children.
When COVID-19 and the flu co-infect, it’s ‘flurona.’ But such cases are rare, and there are effective ways to protect yourself from both viruses.
Canadian scientists have made significant contributions during the pandemic response, including vital roles in developing COVID-19 vaccines. But underfunding puts the future of science in Canada at risk.
Early on, public health messaging focused on the need for vaccines to combat COVID-19. But far less attention has been given to the role of boosters in preventing deaths and reducing inequities.
Fair Work Commission rulings on employer vaccination mandates highlight the need for fair processes.
A major lesson from the COVID-19 pandemic is the need to decolonize transnational governance so that the world is better able to handle both future and current global crises.

Fourth COVID shots have been approved for over-30s, a necessary step to help protect Australians this winter. But we should be doing more.
On the horizon: A new omicron-focused version of the Moderna vaccine that may offer longer protection and a stronger immune response.
With COVID-19 shots finally available for infants and preschoolers, knowing how to combat misinformation on social media and elsewhere could be more important than ever.
The FDA’s authorization of COVID-19 shots for children ages 6 months to 4 years will bring relief for millions of parents. Pending CDC endorsement, shots for this group will be available within days.
To help people make informed decisions about ongoing COVID-19 risks, public health messaging needs to adapt as the pandemic evolves, just as immune systems adapt to new viruses and variants.
Waiving patent rights on COVID-19 vaccines and drugs is still crucial to ensure access globally, but the waiver on the table at the June World Trade Organization meeting doesn’t do the job.
