BUDAPEST -- Hungarian Prime Minister Viktor Orban received an injection of China's Sinopharm vaccine against COVID-19 on Sunday.

"Vaccinated!" Orban wrote on Facebook, posting a photo of himself getting the shot, a close-up of the Chinese vaccine and a picture of a door to the vaccination point where he received the inoculation.

Orban received the shot two days after Hungarian President Janos Ader, who also opted for the Chinese vaccine.

Hungarian Chief Medical Officer Cecilia Muller told a press conference Saturday that it is very important for high-ranking Hungarian officials to get immunized publicly, in order to set an example for the population.

With access to vaccines from five producers, namely China's Sinopharm, Pfizer, Moderna, AstraZeneca and Russia's Sputnik V, Hungary, the first European Union member state to buy and authorize the use of Chinese vaccines, started to administer the Sinopharm vaccine on Wednesday.

The Hungarian government is boosting its vaccination program with Russian and Chinese vaccines, as the third wave of the pandemic has brought daily infections and deaths in the country to the level of mid-December last year.

Hungary on Sunday registered 4,469 new cases and 72 more deaths in the past 24 hours, raising its national total to 428,599 and the death toll to 14,974, according to official data.

So far, 321,128 people have recovered. Currently, 5,482 patients are being treated in hospitals, including 524 on ventilators, figures from the government's coronavirus information website showed.

As of Sunday, 677,682 people have received at least one vaccine jab, while 249,499 have received two jabs, according to the website.

Hungary intends to inoculate all the 2.6 million people registered for the vaccine by Easter, and Orban aims to vaccinate a further million by May.

After the arrival of the first batch of Chinese vaccines on Feb 16, Minister of Foreign Affairs and Trade Peter Szijjarto said Friday that another batch would arrive in Hungary in March.
