As the virus continues to mutate, COVID vaccines are updated. This brings us to the latest announcement about the new ‘monovalent’ vaccines.

COVID-19 remains a global public health threat despite its current non-pandemic status.
We still have much to learn about many aspects of COVID-19 — including its lingering health effects and the mechanics of its endless mutations — but we do know one thing: we can’t let our guard down.
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 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.
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.
A new generation of vaccines and boosters against SARS-CoV-2 may take a page from the anti-influenza playbook, with shots periodically tailored to target the most commonly circulating virus strains.
Boosters and vaccinating children mean we’re relying on two pharmaceutical companies to supply Australia’s COVID vaccines. That needs to change.
Research suggests that too-frequent immunizations may lead to a phenomenon called “immune exhaustion.”
Flu vaccines will soon be available. And this year, you can get your COVID shot at the same time.
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.
Studies suggest seniors without the booster shot run a higher risk of infection and hospitalization from the omicron variant.
If you or your child test positive for COVID, you clearly can’t go to that vaccination or booster appointment you had booked this week. So, when can you go?
Even with a variant like Omicron that may be more transmissible than earlier variants, vaccines remain the most effective tool for protection against COVID-19 and for ending the pandemic.
For a number of reasons, as time goes on vaccines become less effective. So how do researchers calculate how well vaccines are working?
If it’s been six months since your second COVID vaccine dose, it’s time to book in for your booster. Here’s why.
The focus of the government seems to be about how many people can get vaccinated rather than ensuring the greatest protection against severe disease and deaths.
Your body produces antibodies after an infection or vaccine, but these slowly decline over time. New Johnson & Johnson data sheds light on the duration of protection and the need for booster shots.
‘Breakthrough’ infections can happen because of waning immunity or high viral doses. But our vaccines are still excellent at preventing severe disease and death.
You’ll read lots of different figures on this — six months, eight months, more — and that’s because the research is ongoing. We don’t yet have a concrete answer.
