High-income countries have already bought up stocks of the leading COVID-19 vaccines for the foreseeable future.
Selfishness was also a problem when the world was developing vaccines for swine flu and bird flu.
A new set of swine flu viruses have been discovered that are highly adapted to infecting humans – and they’re already spreading among farm workers in China.

A century ago, the influenza pandemic killed about 50 million people. Today we are battling the coronavirus pandemic. Are we any better off? Two social scientists share five reasons we have to be optimistic.
Backyard chickens may seem free and happy, but are at increased risk of contracting diseases from wild birds.
Amid the COVID-19 pandemic, some critics say livestock farms promote diseases that spread from animals to humans. An animal scientist explains how well-run farms work to keep that from happening.

Modelling highlights the urgent need for strong interventions.
The government’s “whatever it takes” promise to NHS is all very well, but UK healthcare is a long way from being ready to deal with a major outbreak.

Initial data from the outbreak in China did not reveal as much information as scientists needed to assess the epidemic. Now, more accurate data suggest an epidemic worse than some previously thought.

Viruses are small enough to pass through filters, including face masks. Disabling viruses with electrically charged gases could be a better way to curb airborne transmission.
The new approach to keep research ready to go could be useful for other health emergencies, including other infectious diseases.
All too often, researchers around the world act in competition when trying to answer research questions in an emergency situation, such as outbreaks of the flu. The UK is trialling a new approach.
Wild boars are being scapegoated for an epidemic of African swine flu that threatens the pork industry.
The flu virus changes over time – which is why you need a different flu shot each year.
Important research questions can almost always be answered better with a combination of methods – where both quantitive and qualitative data play a role.
Congolese health workers prepare equipment before the launch of vaccination campaign against the deadly Ebola virus.
A study of recent epidemics like Zika and Ebola suggests that the media may fail to tell the public what to do during an outbreak.
The protection of the flu vaccine is minimal, and may not be worth it.
Research shows for every 100 healthy adults vaccinated against influenza, 99 get no benefit.
Every year in Canada, there is an average of 23,000 cases of lab-confirmed influenza, 12,000 people who need to be admitted to hospital and 3,500 flu deaths.
As influenza season begins in North America, many people wonder whether to get a flu shot. Our expert delves into the pros and cons of the vaccine and how it works.

What’s on your cash? Studies show our money carries everything from pet DNA and old food to E.coli and traces of cocaine.
But what are the risks?
Computer modelling can help in the fight against the spread of disease.
It took a computer to discover the potential threat of a drug-resistant strain of swine flu that was about to spread from New South Wales. So how close did we come to a global pandemic?
As part of pandemic preparation, in the early 2000s many countries amassed large stockpiles of the influenza neuraminidase inhibitor Tamiflu.
One of the biggest recent controversies in medicine involves the effectiveness of the antiviral drug Tamiflu. Governments have stockpiled the drug but many have raised doubts about its usefulness.
Predicting the severity of the flu season based on one data set paints an unnecessarily scary picture.

Australia’s in the middle of the annual flu season and once again, it’s claimed to the worst on record. But why is it that every season seems to outdo previous ones and how bad is this year, really?
Vaccines have always had potential side effects but they remain our best defence against far more dangerous infectious diseases.
