A prominent Kenyan doctor and conspiracy theorist who became a campaigner against coronavirus vaccines has died from the disease.

Dr Stephen Karanja said it was unnecessary to vaccinate Kenyans against Covid-19.

Instead, he argued for steam inhalation and a cocktail of drugs, including hydroxychloroquine and zinc.

He also spread conspiracy theories, involving Bill Gates and population control.

Dr Karanja died on Thursday in the high dependency unit of a private hospital in the capital, Nairobi.

More than 800,000 Kenyans have now been vaccinated, with no severe side effects being reported.

Before his death, Dr Karanja was the chair of the Catholic Doctors Association, which described him “as a true medical soldier”.
