Vaccines have successfully curtailed viral diseases for decades. But as COVID-19 vaccination hesitancy shows, mistrust and misinformation continue to put lives at risk.
Microbes are everywhere – and they aren’t all friendly.

Scientists get up close and personal with deadly pathogens to give doctors the tools they need to treat people sickened by germs. The key is keeping the researchers – and everyone around them – safe.
The prevention of future pandemics requires examining viral family trees.

Gain-of-function studies make a natural virus more dangerous or transmissible to humans. Could the Wuhan Institute of Virology be the source of SARS-CoV-2?

The lab accident theory of the origins of Covid-19 has gained traction in recent months. We need a proper investigation to find out what really happened.
Sustained surveillance for disease outbreaks at global hot spots may be the key to preventing the next pandemic.
A more coordinated effort by scientists, stakeholders and community members will be required to stop the next deadly virus that's already circulating in our midst.
Scientists have been trying to pinpoint the exact causes of the declines in some wild Pacific salmon populations for decades.
A study of viral variants finds Piscine orthoreovirus continuously spills over from farmed salmon to wild salmon.

Pandemic viruses arise from raising, harvesting and eating animals. Policy strategy for averting the next pandemic should include supporting those already seeking to make plant-based dietary changes.
Fungal viruses have been important in reducing the impact of fungal diseases on chestnuts in Europe.
Technology is allowing scientists to better understand fungal viruses, with the aim of managing them more effectively.
Leeuwenhoek refined the magnifying glass, creating the world’s first microscope.

Cuba's access to internationally produced vaccines was nearly impossible due to the U.S. blockade. Its decision to make its own vaccines stands to pay off handsomely.
Pollen can suppress how the body’s immune system responds to viruses.

As climate change drives pollen counts upward, that could potentially result in greater human susceptibility to other viruses, as well.

As the world has focused on the COVID-19 pandemic, other microbial foes are waging war on humans. Antibiotic-resistant bacteria pose a growing threat. But viruses may defeat them.
For many, distinguishing between fact and fiction is difficult.

With the vaccines now being administered at sites around the US, it is important to address misinformation surrounding the effort.
Fatigue, brain fog, breathing problems and many other COVID-19 symptoms can persist for months.

'Long COVID' – in which people have symptoms lasting more than a few weeks – is turning out to be very common. People hospitalized for COVID-19 are at highest risk, but they aren't alone.
Occasionally, a mutation will give the virus a better chance of surviving and reproducing itself, and will result in a new population (known as a new lineage)

The pandemic will not end for anyone, anywhere until it is controlled in every country. Tanzania’s approach will make it that much harder for normality to return.
Study shows that the Novavax vaccine is effective against the dominant variant of COVID-19 in South Africa.

The results indicate that the vaccine efficacy in the UK was 89% for individuals who received at least two doses of vaccine. In South Africa, the vaccine efficacy was 60% in people without HIV.

Is it time for some scientists to turn back to pre-COVID-19 research?

Ever since the 2001 SARS outbreak and H5N1 avian flu in 2003, we’ve developed tools to monitor diseases that transmitted from animals to humans. But what does a large-scale roll-out entail?
