The long vaccine development process is focused on ensuring production of the safest and most effective vaccine for use.
The Rotavirus vaccine is expensive and takes a long time to manufacture.
Rotavirus vaccines are expensive and take time to produce. For developing countries, the fact that the vaccines need cold storage also presents a challenge.
GMOs may very well have filled up that syringe.

Public health experts enlist the molecular biology tools that create genetically modified organisms – as well as the GMOs themselves – in the fight against emerging infectious diseases.

Individual stories of perceived vaccine harms can undermine trust in vaccine safety, even if people don't believe the vaccine was to blame.

A new animal study has shown injections of antibodies might protect against HIV infection, albeit for only a limited time.
An Ethiopian boy receives a polio vaccination. Africa has done well with polio eradication but lags behind other vaccination efforts.
Every year hundreds of thousands of children die from vaccine-preventable diseases. Africa leaders could change this if they improved vaccination efforts.

Nobel Laureate Barry Marshal discovered that bacteria called Helicobacter pylori caused peptic ulcers. He is using the same bacteria to create probiotics and edible vaccines.

There are demands for older children to get the MenB vaccine – but what is the thinking behind the current guidance?

Two major clinical trials will be conducted in South Africa in 2016 to test ways of preventing new HIV infections.
Polio vaccinators carry boxes of polio vaccine drops as they head to the areas they have been appointed to administer the vaccine, in Karachi October 21 2014.
Researchers are piloting a smartphone app to collect better information about who is getting vaccinated and to design better incentives for health workers on vaccination drives.

In light of the newly ignited political debate about vaccines, here in one article are some of the highlights of our vaccines coverage.
‘Leaky vaccines’ don’t affect the ability of the virus to reproduce and spread to others; they simply prevent it from causing disease.

Media coverage of a recent study involving a "leaky" vaccine raised questions about the possibility that they could make viruses more dangerous.
A health worker injects a woman with an Ebola vaccine during a trial in Monrovia, February 2 2015.
Was the Ebola vaccine 100% effective, or 100% lucky? The good money is on a percentage somewhere in between, but in truth, we will never know.
Hepatitis B is commonly transmitted between children, who are not aware that they are carrying the virus.
Hepatitis B vaccines have been available for over 20 years but the virus is still endemic in Africa, with the continent carrying over one third of the globe's case load.
A vial of measles, mumps and rubella vaccine and an information sheet are seen at Boston Children’s Hospital in Boston, Massachusetts, February 26 2015.
The anti-vaccination movement is not the cause of falling vaccination rates. It is a symptom of the public’s growing distrust in the government and the medical profession.
Children in particular experience a multitude of viral illnesses during their early years.
Viruses cause all kinds of infections from relatively mild cases of the flu to deadly outbreaks of Ebola. Clearly, not all viruses are equal and one of these differences is when you can infect others.
Vaccines have always had potential side effects but they remain our best defence against far more dangerous infectious diseases.

When the measles vaccine was introduced, it was associated with reductions in more childhood disease deaths than were actually caused by the measles. How does that work?
