Covid-19 vaccines

The People's Vaccine Alliance says nearly 70 lower-income countries will only be able to vaccinate one in 10 people.

This is despite Oxford-AstraZeneca pledging to provide 64 percent of its doses to people in developing nations.

Steps are being taken to ensure access to vaccines is fair around the globe.

This vaccine commitment, known as Covax, has managed to secure 700 million doses of vaccines to be distributed between the 92 lower-income countries that have signed up.

The World Health Organization (WHO) says the world's not only fighting the pandemic, but also what it calls an "infodemic" - where an overload of information, some of it false, makes it difficult for people to make decisions about their health.

And it's trying to answer people's concerns about the vaccines - as well as helping people evaluate the information they see on social media.

Nina, who is 21 and lives in London with her 82-year-old grandmother, is one of those who has concerns,

She says she has "mixed feelings" about Covid vaccines.
