Could the yearly flu shot become a thing of the past?

Flu virus mutates so quickly that one year's vaccine won't work on the next year's common strains. But rational design – a new way to create vaccines – might pave the way for more lasting solutions.
It's still unclear whether Zimbabwe will manage an effective transition to participatory democracy and freedom. And the current signs are not encouraging.
Using the right metaphor in science is important.
Parents are concerned combination vaccines, which protect against several diseases at once, can be too much for a young immune system to cope with.
Vaccines against multiple diseases in one jab strengthen kids' immune systems, not weaken them. Here's why we shouldn't fear these combination vaccines.
It’s the ability of our immune system to remember past infections, and pass this memory on to our kids, that allows us to survive infectious diseases.
With so many microbes capable of hijacking and destroying us, how are we, as a species, still enduring?
What if it wasn’t back to the drawing board every year for a new flu shot?
Flu virus mutates so quickly that one year's vaccine won't work on the next year's common strains. But a new way to create vaccines, called 'rational design,' might pave the way for more lasting solutions.

Aedes aegypti mosquito, which can spread dengue and Zika on February 4, 2016.
Emerging research suggests that preexisting immunity to dengue virus, which is endemic in South America, could make a subsequent Zika infection worse.
South Africa’s planned withdrawal from the ICC is considered a detraction from Nelson Mandela’s “inspiring legacy”.
The ICC has made important advances by investigating cases outside Africa and completing ones that further define what is not allowed in war. South Africa’s withdrawal is concerning, but not fatal.

The long vaccine development process is focused on ensuring production of the safest and most effective vaccine for use.
There's an effective vaccine – but it's not always the best option.
Most people know sleep is important. But few know a lack of it can put us at greater risk of heart disease and obesity.
Not getting enough quality sleep can have significant implications for health.
Our modern crops need some help in the immunity department.

Modern agriculture is synonymous with monoculture. That lack of diversity is bad news for plants' natural immune defenses. Researchers are figuring out how to help plants fend off microbes – without pesticides.
The only thing standing between invaders such as bacteria, viruses, parasites and fungi and our devastation is our immune system.
The immune system does such a good job most of the time that we only really think about it when things go wrong. But to provide such excellent protection, it must constantly learn.
The immune system protects us from the constant onslaught of viruses, bacteria and other types of pathogens we encounter throughout life. But it can sometimes misbehave.
There are lessons to be learnt about the ICC from the Kellogg-Briand Pact, signed in 1928. It failed to prevent the outbreak of war but brought war criminals to justice later.
The ICC has not lived up to its noble intentions of making the world more just. Its failure echoes that of the 1928 Kellogg-Briand Pact, which set out to banish wars and to settle disputes peacefully.
