Washington DC - White House Press Secretary Jen Psaki has contracted the coronavirus despite being vaccinated.

In a written statement posted on Twitter, Psaki said he had tested positive on Sunday.

Psaki did not accompany President Joe Biden on his trip to Europe and said she last met her boss last Tuesday amidst special protective measures.

Last week, Psaki had cancelled her trip with Biden to the G20 summit in Rome and to the world climate conference in Glasgow at short notice, initially citing a "family emergency" as the reason.

In her statement on Sunday, Psaki said that a member of her household had tested positive for coronavirus.

She then went into quarantine and got tested on Wednesday and Thursday, as well as on Friday and Saturday. All of these tests were negative. But a test on Sunday was positive.

Psaki said she was making her test result public in the interest of transparency.

Given her vaccination against the coronavirus, Psaki said she only has mild symptoms and can continue working from home.

She plans to return to the White House after a 10-day quarantine and a negative test result.
