This week had a promising start as footballers endorsed vaccination at the Africa Cup of Nations, and leaders from across the African continent united in their support of access to immunisation for all children.

Vector borne disease continued to cause concern as yellow fever threatened cities in Brazil, the spread of drug resistant malaria demanded attention, and a possible Zika vaccine took a small step forward.

NPR explored the origins of germs for which we now need vaccines, and a survey of the US public found that the majority of people recognise that the benefits of measles, mumps and rubella vaccines outweighed the very small risks. Across the other side of the world, the Indian government also launched a massive immunisation campaign aiming to protect children against measles and rubella.

Finally, this Saturday marked World Cancer Day, drawing commentary on the power of vaccines to prevent certain types of cancer, and their importance in preventing a cancer crisis in lower income countries.
