Even taking into account people who have had COVID but didn’t know it, there’s still likely to be a group of people who have never been infected.
Sales of vitamins are booming in pandemic times. But is there any evidence that vitamin and mineral supplements can protect you from COVID or help you recover from infection?
Are you due your third or fourth dose? What about your parents? What about your kids? It can be hard to keep track, so here’s the current advice.
Your blood can hold a record of past illnesses. That information can reveal how many people have had a certain infection – like 58% of Americans having had COVID-19 by the end of February 2022.
As little as 30 minutes of exercise five times a week can benefit your immune system.
Fourth doses are now being offered to vulnerable groups. But if you’re young and healthy, will you need one?
The metaphor of a collective “carpet of immunity” invites us to imagine immunity as a collaborative project, spreading out to protect those for whom the end of mandates means increased vulnerability.
It feels like everyone around you has or is recovering from COVID. Maybe you’re fatigued and wondering if it’s an after-effect? Antibody tests could confirm it one way or another.
The COVID-19 pandemic has brought immunology terms that are typically relegated to textbooks into our everyday vernacular. These stories helped us make sense of the ever-evolving science.
COVID cases are predicted to rise as we face another variant. So a 4th shot to top up our immunity is looking more likely as we head into winter.
Whooping cough rates are the lowest they’ve been for years. But what comes next?
Taking OM85 could lower the risk of developing asthma by protecting babies’ lungs from damaging infections in the early years of life.
One study suggests the virus takes an average of 36 days to clear from the body after symptoms first appear.
Many Australians are yet to have a third COVID vaccine dose, while people overseas are having their fourth shot.
Infection seems to add a boost to immunity – but vaccination is still vital and breakthrough infections should be avoided as much as possible.
Some of the omicron variant’s unique properties – such as its ability to spread rapidly while causing milder COVID-19 infections – could usher in a new phase of the pandemic.
Variant-specific vaccines would undoubtedly increase immunity. But waves of new variants would engulf the population faster than these vaccines could ever be deployed.
For a number of reasons, as time goes on vaccines become less effective. So how do researchers calculate how well vaccines are working?
Careful lab work will complement public health data as researchers worldwide focus on omicron, asking questions about contagiousness, severity of disease and whether vaccines hold up against it.
If it’s been six months since your second COVID vaccine dose, it’s time to book in for your booster. Here’s why.
