This weekend was marked by marches for science around the world, including some healthy support for vaccination via pithy placards. The marchers weren’t alone, as earlier in the week Bill Gates was once again advocating the benefits of vaccination for children around the world, and the foreign aid that supports it.  Polio survivor Minda Dentler spoke out along the same lines, and development publication the Humanosphere catalogued the remaining challenges for global polio eradication.

Nigeria continued to immunise hundreds of thousands of people against meningitis, in a bid to control an emerging outbreak, and concerns were raised about rising measles cases in Italy.

In the run up to World Immunisation Week (24-30 April), the Financial Times published a special issue on vaccination, and innovative quiz masters I Boost Immunity shared the vaccination questions people most often get wrong on their site. Would you have done any better?
