she wants to report the possible breakthrough positive; she wants to report the possible breakthrough positive/has no symptoms; This is a spontaneous report from a contactable consumer. This consumer (patient's mother) reported for a 18-year-old female patient (her daughter, age at vaccination: 17 years) received first dose of BNT162B2 (PFIZER-BIONTEC COVID-19 mRNA VACCINE, Solution for injection, lot number: EW0176 and expiry date was not reported), via an unspecified route of administration, on 27Apr2021, as a single dose for COVID-19 immunization and second dose of BNT162B2 (PFIZER-BIONTEC COVID-19 mRNA VACCINE, Solution for injection, lot number: EW0176 and expiry date was not reported), via an unspecified route of administration, on 18May2021, as a single dose for COVID-19 immunization. The patient's medical history and concomitant medications were not reported. The reporter stated that her daughter received the second dose on 18May2021 and was an athlete and attending a university where they did weekly tests and had to get a TB skin injection test on 01Sep2021 at 345 and then had a saliva Covid test the next day at 6pm and got a positive test result on 04Sep2021 with a rapid follow up with a negative result. The reporter stated she was not seeing information to see if the TB skin injection test would affect the validity of the Covid test in that time period. Her test was possibly being re-ported as a breakthrough positive test for Covid. She hasn't seen that you shouldn't get a TB test after a certain time of getting the covid vaccine and was asking about data on an injectable TB test and then the Covid test. The reporter stated she wants to report the possible breakthrough positive on an unspecified date. She was concerned about a false positive and was questioning whether she did have Covid or whether the TB test interfered with the validity of the Covid test and wanted to report it. The rapid test was done anyway and was negative. She was quarantining now. The game was at 7pm but mom was called after 4pm with the results; she was not sure when the rapid test was done. She was questioning due to the TB test, could that have caused a false positive, she was asking about the valid of the Covid test with the TB test and was concerned it was a false positive because of the 2 being done so close together. The reporter explained her daughter was in quarantine as the university considered the first test to be accurate. She has not seen anything in the literature about this, that taking the 2 test would result in a false positive. The state explained they run the test 3 times to make sure it is positive, regarding the saliva test that was positive. Her daughter did not have any symptoms and so she was wondering since now they don't test her anymore for Covid now that she tested positive, if the TB test does affect the validity they were attributing the breakthrough to our vaccine and they shouldn't bet. Otherwise, she did contract Covid and is a breakthrough but seeing as she has no symptoms. There was a Product Complaint. The patient underwent lab tests and procedure included Rapid Covid test with unknown results on an unspecified date and with negative result on 04Sep2021, saliva Covid test with positive result on 02Sep2021 and with negative result on 04Sep2021, and TB skin injection test with positive result on 01Sep2021. Outcome of the events was unknown.
