Additional Information: GSK Receipt Date: 11-SEP-2024 Healthcare provider left voicemail stating about defective FluLaval TIV syringes. The lot number was J4349. They have noticed the syringe was very bad at holding the needle securely. Just the pressure alone of pushing the vaccine out was enough to make the needle unscrew, and it had happened twice now inside of a patient. A few other people within company had reported this. No patients had been harmed. The needle of 25 gauge 5/8 inch was used. She said that it was the same brand of needle that she used for other GSK vaccines. She stated that she had used this same needle brand/size with other GSK Flulaval 2024-2025 season vaccines with a different lot number and did not had a problem with those. She thought that the problem was only with lot number J4349. She had lost confidence in that lot only because she had a problem of looseness with 3 boxes with lot J4349. She had unopen boxes of lot J4349 and she was reluctant to use them. She had one open box with lot number J4349 that has 4 unopen syringes. She will be sending those 4 unopen syringes back to GSK quality with an unopen needle. She was requesting a shipping box. The leur lock did not break off, the needle unscrewed off. When removing the cap, it screwed off. She said when she was screwing them on it felt unsecure. She said she could see how far to tighten it and she was not over-screwing them. She said that with two (pediatric) patients when injecting the needle did not stay all the way on and so some of the medication squirted out the side instead of into the patient (Adverse event related- Underdose). The doctor did not feel that either of these patients required a re-dose. Both of the patients were pediatric and sometimes pediatric patients can move around but both of these patients were calm during administration. She noticed that she could see the orange needle guard spinning as she was injecting the medicine which meant that the needle was unscrewing. Three boxes (26 syringes) with the lot number J4349 had the looseness. She stated that she can feel it when she attached the needle that it was loose and that even if she just bumps it with her thumb the needle will unscrew and come off. Those 26 syringes had been used and are in the sharps container. But she did take a video and will email that. She said that she got an email from the manager of two other clinics that also reported an issue with Flulaval syringes. She did not know how many syringes were affected by the other clinics and did not know the lot number of the syringes the other clinics were using.; Sender's Comments:  US-GSK-US2024113158:Same reporter
