A Health Ministry file indicates that former Brazilian President Jair Bolsonaro, an outspoken skeptic of COVID-19 vaccines who has vowed never to receive the vaccine, could have been vaccinated in 2021, Reuters reported.

The country’s comptroller general’s office said it was examining a vaccine card issued by the Health Ministry that records the far-right former president’s vaccinations, although it warned the card could have been forged.

He said he requested information about Bolsonaro’s vaccinations from the Health Ministry after the inauguration last month of new leftist President Luiz Inacio Lula da Silva.

“As far as we know, the record exists,” Comptroller General Office chief Vinicius Carvalho told CNN Brazil.

Since the outbreak of the COVID-19 pandemic in 2020, Bolsonaro has repeatedly made public statements downplaying the importance of vaccines and stating that he has not been vaccinated and will not be vaccinated. In 2020, he was ill with COVID-19.

Bolsonaro said last week he planned to return to Brazil in March after spending more than a month in the United States to lead the political opposition to Lula and defend himself against accusations of inciting post-election protests.

Bolsonaro left for Florida two days before Lula was sworn in on Jan. 1 and later applied for a six-month tourist visa to extend his stay in the United States.
