Spending more time in nature may be associated with less fear of germs.
A fear of microbes, like germs, could be harming human health.
Infection from the coronavirus can produce weaker immunity than vaccination.

COVID-19 vaccination produces a more consistent immune response than a past infection. With the delta variant, the difference in protection may be even greater.

At the height of polio and H1N1, Canadians were keen to get vaccinated, but vaccine enthusiasm waned once the crisis had passed — what does that mean for COVID-19?
Vaccinated people are well protected from getting sick, but could they inadvertently transmit the coronavirus?

The COVID-19 vaccines are a smash success. But that doesn't mean they keep every vaccinated person completely free of the coronavirus.

Vaccination rates for COVID-19 have been lower than desired for herd immunity, or when enough people become immune for new infections to stop. What will life look like without it?
It's quite likely this virus will never be eliminated from the world. But even so, getting vaccinated enormously reduces your risk of severe outcomes like hospitalisation and death.
A person’s resting metabolism is very sensitive to temperature, and offices are often too cold for people.
Going back to work at an office? An expert explains how the relatively cool temperature many offices are kept at may affect your body – and your health.

Meeting the recommended guidelines for physical activity reduces the risk of falling ill and dying of infectious diseases by 37%.
Vaccination produces a much stronger and more consistent immune response than infection.

If you've already had the coronavirus and recovered, you might be tempted to give the vaccine a pass. A scientist explains why the shot offers the best protection against future infection.
Giving smaller vaccine doses in multiple shots is often more effective than a larger single dose.

Injected vaccines tend to generate good immunity overall but less of a response in the nose and throat, where the virus enters and spreads from.
New mRNA vaccines use genes from the coronavirus to produce immunity.

So far, most vaccines in the US are mRNA vaccines. These represent a new technology and are likely to take over the vaccine world. But how do they work? What are their weaknesses? Five experts explain.

You've been vaccinated; can you now safely see your friends and family? New research hints that vaccinated people may be less likely to transmit the coronavirus, but they are not 100% in the clear.
For elite athletes, even mild COVID-19 vaccine side effects can throw their training plans off course. But they can plan ahead.
Our research could be important for developing more effective vaccines in the future.

We mapped the genes of B cells to better understand why some develop immunity and others don't.
We have limited information about the reported deaths of 30 elderly people in Norway who had received the Pfizer COVID vaccine. Here's what we do know.
Before the U.S. can return to some form of normal, a lot of people need to be vaccinated.

Researchers say around 70% of the US needs to get the coronavirus vaccine to stop the pandemic. But questions around the vaccines and regional differences add some uncertainty to that estimate.
With a vaccine now approved in the UK, other countries won't be far behind. But a vaccine won't singlehandedly ensure the virus doesn't cross international borders when travel picks up.
It's not only shedding and reinfection which are different — there are actually two types of viral shedding.
Distributing a vaccine is a bit like boarding a plane — we can’t all board at the same time. So who gets priority? There are a few reasons we should consider vaccinating older people first.
