Media coverage of a recent study involving a "leaky" vaccine raised questions about the possibility that they could make viruses more dangerous.

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.

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.
