The venom of Sydney funnel-web spiders goes into rabbits, which are immune to the toxins. The animals are injected with increasing doses to build up their antibodies. In some cases, that step alone can take almost a year.The animal's supercharged plasma is removed from the blood, and then the antibodies are isolated from the plasma before they're bottled, ready to be administered.

CSL Seqirus makes 7,000 vials a year – including snake, spider, stonefish and box jellyfish antivenoms - and they are valid for 36 months. The challenge then is to ensure everyone who needs it has supplies."It's an enormous undertaking," says Dr Jules Bayliss, who leads the antivenom medical team at CSL Seqirus."First and foremost we want to see them in major rural and remote areas that these creatures are likely to be in."

Vials are distributed depending on the species in each area. Taipans, for example, are in northern parts of Australia, so there's no need for their antivenom in Tasmania.Antivenom is also given to the Royal Flying Doctors, who access some of the nation's most remote communities, as well as Australian navy and cargo ships for sailors at risk of sea snake bites.

Papua New Guinea also receives about 600 vials a year. The country was once connected to Australia by a land bridge, and shares many of the same snake species, so they're given the antivenom for free – snake diplomacy, if you like.

"To be honest, we probably have the most impact in Papua New Guinea, more so than Australia, because of the number of snake bites and deaths they have," says CSL Seqirus head of manufacturing Chris Larkins. To date, they reckon they've saved 2,000 lives.US President Donald Trump has also repeatedly said the country would be better off as a 51st US state.

At the airport, the Queen was given a bouquet of flowers and she and the King were greeted by school groups from the provinces of Ontario and Quebec.Some of the children who attended the arrival are enrolled in the Duke of Edinburgh programme, a global youth development programme launched by the late Prince Phillip - the King's father - in 1956.

After the airport greeting, the King and Queen travelled to Lansdowne Park in central Ottawa, where they met well-wishers, local community groups, farmers, and vendors.The King took part in a ceremonial street hockey puck drop.
