Three months since the Ebola outbreak was declared in the Democratic Republic of the Congo, more than 1,900 people have died from the virus, with more than 4200 confirmed cases, making this the second-worst Ebola outbreak ever.

Andrew also updates Claudia on news that US President Donald Trump has signed an order that calls for fewer childhood vaccines and which also recommends splitting the mumps, measles and rubella (MMR) shots.
