Hungary will be able to vaccinate millions more people by the end of May than other European countries with similarly sized populations due to its plans to use a COVID-19 vaccine made in China, reported AP citing Prime Minister Viktor Orban.

"If we start using the Chinese vaccine, which will happen soon, then by Easter we can vaccinate every person who has registered so far," the prime minister said. 

Nearly 2.5 million people have signed up to receive COVID-19 vaccines in the country.
