More than 70 per cent of the world’s population has received at least one COVID-19 vaccination.
New analysis answers questions about the ongoing effectiveness of COVID vaccines: How well they protect against infection, hospitalization and death months after initial doses or after a booster shot.
COVID-19 hasn’t vanished, but at this point it’s doing less damage.

From cancer immunotherapy and antibiotics to GMO crops and pandemic surveillance, gain of function is a cornerstone of basic research.
COVID-19 is still with us, and is still causing serious illness and death. However, it is disproportionately affecting older people.

COVID-19 is the third-leading cause of death in Canada, but it’s older people who are dying. That we accept this and carry on as if the pandemic is over reveals our ageism: We don’t value older people.
A team from the University of Tours and INRAE is working on the development of an innovative nasal vaccine against Covid, in spray form.
Vaccination is often combined with an injection. It can also take the form of a nasal spray: an approach that is still rare, but which could be effective against Covid. Here’s why.
COVID-19 emergency status prompted coordinated vaccination efforts by health care providers, paramedics, volunteers and others.

President Joe Biden’s intention to end the national COVID-19 emergency will have long-lasting ripple effects on federal programs such as Medicare, Medicaid and the Children’s Health Insurance Program.
The FDA advisory committee discussed vaccine safety, effectiveness of the current shots, potential seasonality of COVID-19 and more.

Many questions remain about next steps for US vaccine policy. But the FDA advisory panel’s hearty endorsement of a single-composition COVID-19 vaccine represents a pivotal step.
XBB.1.5 is rapidly spreading across the globe and will likely become the next dominant COVID-19 subvariant.
The XBB.1.5 subvariant — nicknamed ‘Kraken’ — is arguably the most genetically rich and most transmissible SARS-CoV-2 Omicron subvariant yet.
Nasal vaccines for COVID-19 are still in early development.

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.
Throughout the pandemic, much discussion about COVID-19 transmission focused on individual-level decisions, making it easy to blame the unvaccinated.
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.
As of Nov. 30, 2022, 62.5% of children and adolescents are unvaccinated against COVID-19.

Nurses who identify as Democrats have a significantly higher likelihood of having their children vaccinated against COVID-19 than those who identify as Republicans.
Pediatric emergency rooms in some states are at or over capacity due to the surging number of respiratory infections.

Respiratory viruses are hitting young children and infants particularly hard this fall and winter season, and experts don’t yet know exactly why.
Model of an influenza virus. Flu season is expected to make a big comeback this year.
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.
Media literacy can help you tell the difference between real and false news.

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.
It is safe to get the newly formulated COVID-19 booster shot and the flu shot at the same time.

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.
Funding research is essential to meet future health challenges.
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.
As of August 2022, COVID-19 vaccination rates in Black and Hispanic people exceeded those of white Americans nationally, but only for the initial shots.

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.
