she recently tested positive for the Tick-borne Illness; she recently tested positive for the Tick-borne Illness/blood test came back with the number 41; rash that she had before she had gotten the vaccine was not get any better in facts it's getting larger; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP). The reporter is the patient.  A female patient received tick-borne encephalitis vaccine (TICOVAC), as dose 1, single (Batch/Lot number: unknown) for immunization. The patient's relevant medical history included: "rash", start date: 2021 (ongoing), notes: had before she had gotten the vaccine; "insect bite", start date: 2021 (unspecified if ongoing). The patient's concomitant medications were not reported. The patient called in to verify a question for her dermatologist. Last year sometime, she went on a trip, something happened, they believe it to be some sort of insect bite and she got a rash and then after getting the rash she ended up getting a single dose of the TicoVac vaccine. Not because she thought it would cure it but because and knew that she be going in the area that they have ticks, and such prevent any further issue she got the vaccine. Then, after coming home she noticed that the rash that she had before she gotten the vaccine was not get any better in facts it's getting larger. She said that she did not believe that it was directly affected by the vaccine. She did not think the vaccine was making it worse, she just noted that, it was not getting better. Now, her question was actually related saying because now, that she was back, she recently tested positive for the Tick-borne Illness, but the dermatologist was wondering if there was a possibility that the vaccine was the reason she was testing positive on the blood test and not actually because she has the virus but they were not sure. Her rash did not affect, get worst after getting the vaccine as well as her testing positive for Tick-borne Illness after receiving the vaccine. She did not think that it was due to the vaccine. Now, she was looking into getting a secondary dose that she plans on travelling again. She said that her blood test came back with the number 41. She could not tell the exact name of the virus that came back testing positive.
