*The 67-year-old, who had contracted the coronavirus in January, said he wanted to encourage all older adults to also get vaccinated. "We're sure there is no risk, no danger, that there are no serious side effects," he said.
The European Medical Agency (EMA) is due to announce the results of a review on whether some cases of blood clotting in adults may be linked to the AstraZeneca shot.
South Korea's food and drug safety ministry said on Wednesday it had granted final approval for Johnson & Johnson's (J&J) vaccine after a panel of experts ruled the single-dose shot was safe and effective.
Ukraine received its first batch of 215,000 Sinovac doses in March to boost its vaccination programme, which has lagged behind many other European countries and it has so far relied on a single batch of AstraZeneca vaccines from India.
"The vaccines of the Chinese company Sinovac Biotech can be trusted," it said.
The decision was made following new reports from medicine monitoring agency Lareb and discussions with health authorities, a Health Ministry statement said.
"Authorities in the UK, European Union, the World Health Organization have concluded that the benefits of using our vaccine to protect people from this deadly virus significantly outweigh the risks across all adult age groups," it said.
