Argentine President Alberto Fernandez has tested positive for COVID-19, about two months after receiving a dose of the Russian Sputnik V vaccine, CNN reports.
Fernandez wrote on Twitter on Friday that he received a positive antigen test after observing a temperature of 37.3ºC (99.14ºF). Another PCR test confirmed this diagnosis.
“I am now isolated, following this protocol and following my doctor’s instructions,” Fernandez tweeted in Spanish. “I contacted the people I met in the last 48 hours to see if they were in close contact.”
Although we are waiting for confirmation by PCR test, I am already isolated, following the current protocol and following the instructions of my personal doctor.

CNN notes that it is still possible to become infected with the coronavirus after receiving a vaccine that has been shown to reduce the likelihood of infection and especially severe infection. An analysis published by the British medical journal The Lancet in February found that the Russian Sputnik V vaccine was approximately 91.6 effective.
The Gamalea Institute, the Moscow-based institute that developed the Sputnik V vaccine, wished Fernandez good luck on Twitter.
“We are sad to hear this. Sputnik V is 91.6% effective against infection and 100% effective against severe cases. If the infection is really confirmed and occurs, vaccination provides a speedy recovery without severe symptoms. We wish you a speedy recovery!” the institute wrote on Twitter.

The start of the introduction of the Argentine vaccine was marked by a scandal, CNN notes, after it was revealed that about 70 people received early access to the COVID-19 vaccine, including Fernández.
According to the World Health Organization (WHO), Argentina has confirmed more than 2.3 million cases of coronavirus and more than 56,000 deaths.
