You may be aware of the fact that there’s a viral claim going on on Facebook that has been telling users that they will be testing positive for COVID-19 if they’ve gotten flu shots in the past ten years. 

Factcheck.org analyzed the claim, and they said that vaccine and infectious disease experts told them that this is completely false and that the FDA has not observed this in authorized tests.

Social media users have been spreading a false claim all over the Internet saying that the flu vaccine will lead to a false-positive test result for the COVID-19

“If you had a flu shot you will get likely get a false positive on a covid19 test,” a Facebook post claimed as cited by the website that we mentioned above. Other posts said: “If you’ve gotten flu shots during the past ten years, you will test positive for the Wuhan strain of the Covid-19 flu.”

The claim is not true 

That’s false, according to experts in vaccines and infectious diseases, as noted by the same website which also highlights that the reference to Covid-19 flu is totally incorrect. 

It’s also worth noting that the flu shots are made using inactivated and not infectious flu viruses or with a single gene from a flu virus in order to produce an immune response from the organism, according to the reports from the Centers for Disease Control and Prevention. 

Also, another important thing worth noting is the fact that the nasal spray vaccine is made with weakened flu viruses. It will take about two weeks after someone gets vaccinated for the body to develop antibodies that will be helping protect against the file. 

The website mentioned above notes that Dr. Paul A. Offit, director of the Vaccine Education Center at Children’s Hospital of Philadelphia, told them in a phone interview that the “PCR tests” (polymerase chain reaction tests) that are used to identify active COVID-19 infections look for “genetic fragments that are unique to this coronavirus.”

Long story short, this means that traces of influenza wouldn’t result in a positive result for COVID-19. Check out the whole explanation in the original post
