Slovakia has started using a new Covid-19 vaccine made by the US firm Novavax, which experts hope will win over sceptics as it is made with time-honoured technology.

“Vaccination with the new vaccine began in two hospitals on Thursday, more will follow,” health ministry spokeswoman Zuzana Eliasova told AFP.

She said that by Monday, Nuvaxovid should be available at 46 vaccination centres across the country.
