Polio can be circulating through a community long before anyone is paralyzed. Monitoring sewage for the virus lets public health officials short-circuit this 'silent transmission.'
In this April 14, 1947 file photo, a long line winds toward the entrance to Morrisania Hospital in the Bronx borough of New York, where doctors were vaccinating against smallpox. In an attempt to halt the spread of the disease, officials said city residents were being vaccinated at the rate of eight a minute.
Humans have shown that together we can overcome daunting problems, including deadly pathogens like smallpox. It is a lesson of international cooperation and respect that we should pay attention to.

Banning travel might not always be the best way to respond to a disease outbreak.
Cases of measles are on the rise as a cohort of unvaccinated children grows up.
Studies suggest that pregnant women might be influenced by medical myths on social media.
Pregnant women often get medical information from social media and websites, many of which contain misleading and false information about vaccination. Could OB-GYNs help educate them better?
The diphtheria vaccine is safe and effective.
International outbreaks of the almost-forgotten disease diphtheria and pockets of low immunisation coverage put Australians at risk of catching the disease.
Vaccinations have saved countless lives and untold suffering, even though many adults still believe vaccines are bad for their children.
Vaccines have long been considered safe, but many people still believe they are not. A new study shows that people who think they know more than medical experts are more likely to believe that vaccine are not safe.
To reduce the incidence of hepatitis B in Canada and to reduce mother-to-child transmission, it is vital that we vaccinate all infants at birth.
To meet World Health Organization targets and reduce the rates of chronic hepatitis B infection among children, Canada should implement routine vaccination of all infants at birth.
Everyone has to be vaccinated for immunisation programs to work.
Stating a majority of people won't benefit from a vaccine ignores the purpose of immunisation programs.
A vaccine (toxoid) against diphtheria first became available in Toronto in 1926. Thanks to the work of the Toronto Diphtheria Committee, the city was diphtheria-free by 1940.
Toronto's fight against diptheria teaches us the powerful impact of public health campaigns -- in persuading parents to vaccinate their children.
When British parents are informed of the risks of HPV, they want their sons to be vaccinated against the virus.
Giving pregnant mothers the flu vaccine protected their babies from getting the flu in the first six months of life.
Complementary medicine practitioners could prove to be a valuable source of information about vaccinations.
Australian parents who visit complementary health practitioners are less likely to vaccinate their kids. But could these practitioners be best placed to educate sceptical parents about vaccination?

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.
