A Republican member of the US House of Representatives, Kevin Brady in a tweet said he had tested positive to COVID-19 after taking the first dose of the Pfizer-BioNTech vaccine shortly before he was due to receive the second dose.
Bradly in his tweet said, “Tonight the Office of House Physician informed me that I’ve tested positive for COVID-19 and am quarantined.
“As recommended, I received a first dose of the Pfizer vaccine on December 18 and also recently tested negative for COVID on New Years Day.”
The United States has authorized the emergency use of two coronavirus vaccines – Pfizer and the one developed by US pharmaceutical company Moderna whose dosing regimen is also two full shots, one month apart.
The lead scientist in the United State’s COVID-19 response taskforce, Moncef Slaoui said the US government is thinking about reducing the doses for some people in other to speed up the vaccination process.
On Tuesday, the US Food and Drug Administration recommended reducing the dosing.
