There’s loads of misinformation online about vaccines. For years, there have been false claims about the tetanus jab causing infertility. One of our listeners, Henry, got in touch to ask us if they were true. Fauziyya Tukur, a BBC Disinformation journalist in Abuja, looks into the claims with us.

The BBC's medical editor, Fergus Walsh explains why vaccine hesitancy is on the rise around the world - and the impact vaccines have had on global health. And we hear from Sahar Baloch, a BBC journalist in Islamabad, who talks about efforts to eradicate polio in Pakistan, amid misinformation about the jab (fuelled in part by a CIA fake vaccine campaign to seek out Osama bin Laden!).

On Sunday night, a surprising exit poll was announced for France’s parliamentary election. It showed that the New Popular Front was about to win the second round, in a result that no-one was expecting.

All previous predictions had suggested the far-right National Rally party would come out on top, but it came third.

The New Popular Front, a brand new left-wing coalition, was formed as part of a strategy to block seats from the National Rally. And even though the plan worked, the National Rally still got its best result in history. But now no party has a majority, meaning France will have a hung parliament.

BBC Journalist, Sara Menai, takes us through what happened and what it means for France.

Dating apps like Tinder, Bumble, Hinge, Match have changed the way many of us date, offering convenience, choice and connection at your finger tips. They have millions of users worldwide. As many as one in three adults in the U.S. has used them, according to Pew Research Centre. But now, ten years after their boom, there’s endless chatter about deleting them. And it’s not because people are finding their Mr or Mrs Right. Some people are opting for advice online and paid coaching programmes instead.

Özge Özdemir from BBC Turkish has looked at the research. She tells us how attitudes are changing about online dating. She’s spoken to psychologists, journalists and young daters about the cultural shift and gives us an overview.

Some app developers have been accused of deliberately making their apps addictive. Elias Aboujaoude a psychiatrist from Stanford University, in the US, explains how some people get hooked.

Also, we get some dating tips from Anwar White, an American dating and relationship coach who specialises in advice for professional women, and women of colour.
