US Army bosses are investigating after three service personnel went to get a flu shot on base - only to be given a dose of Pfizer's COVID vaccine instead.
Army officials confirmed the accidental doses were administered at the Joint Base Lewis-McChord in Washington earlier this month, to three unidentified people.
'Joint Base Lewis-McChord is aware three people were inadvertently administered the Pfizer COVID-19 vaccine instead of another vaccine at the Lewis Main Exchange,' Col. Joey Sullinger with I Corps Public Affairs told the Military Times.
An online poster first reported the accidental vaccination on Twitter on October 26
Sullinger added that 'positive corrective action has been taken at this vaccination site to prevent such errors from happening again,' and that 'Army medical professionals are notifying and ensuring the health and welfare of those affected.'
The incident is currently under investigation and according to an online poster, those jabbed had been hoping to get their flu shot, only to receive the Pfizer COVID-19 vaccine instead.
It is not known if the three people accidentally vaccinated were already fully vaccinated against COVID-19.
The Public Affairs at Joint Base Lewis-McChord told the DailyMail.com that the three people's vaccination status was protected by HIPPA.
Service members are already required to get up to 17 different vaccines, depending on where in the world they are stationed, including jabs for measles, mumps, diphtheria, hepatitis, smallpox and the flu.
All military personnel must be fully vaccinated by November 28, under the Defense Department's August mandate

The United States Department of Defense reported administrating 5,867,468 total COVID-19 vaccines
All military personnel must be fully vaccinated by November 28, under the Defense Department's August mandate.
Currently hundreds of thousands of United States servicemembers remain unvaccinated or are only partially vaccinated against the coronavirus, as the deadline to have the shot draws closer.
As of October 10 only 72 percent of the 181,000 active Marine Corps personnel have been vaccinated - meaning close to 51,000 have yet to have the jab.
On Saturday the Marine Corps made it clear that those who refuse the jab will be kicked out.
'Marines refusing the COVID-19 vaccination, absent an approved administrative or medical exemption, religious accommodation or pending appeal, shall be processed for administrative separation,' the corps warned in a message.
There has been some pushback to the military vaccine mandate.
In September, Army Lt Col Paul Douglas Hague resigned and gave up his pension after more than 19 years of service because he refused the 'unethical, immoral and tyrannical' vaccine mandate.
In Hague's resignation letter-which he wrote on August 23, the day after the Pentagon announced all active military were to get vaccinated immediately - Hague said he refused to 'sit still and allow a serum to be injected into my flesh against my will and better judgement'.
To date, the Department of Defense has administered 5,867,468 doses.
The DOD reported a total of 248,865 positive cases of COVID-19 across all services, with 1,283 new cases between the week of October 13 and October 20.
