Now they don't know where they were going to get the second shot because the deadline was expired like it requires certain day. They give them the 28 to give the second shot and today he was missing, now he did not get the second shot and he was worrying about that why they got the first shot why they didn't give up the second shot because they were not giving anymore and that was what those people needs to think. They were giving the shot to everybody he asked the lady, he live in  was it okay for him to get the shot. They said sure because he was a business owner he want to save some time. He got the shot with his son, his son did not have any side effect and he was okay. he did develop the same time when they give him the vaccination, about 2 minutes later he started developing headache. he told me please sit down here, he waited there for 15 minutes, closed his eyes for some time and the headache started getting light and then he stood up, he went home. he come home and he just lay down and the headache stay very lightly and he go to sleep, next day morning he don't have headache it' gone but we (Not appropriately clarified, hence split case was not made) missed the second dose and he don't know where to get the second dose. Patient was asking Where they have to contact the vaccination center, where they have to call can they go to the pharmacist to tell them, to reschedule. Was it not too late to get the second shot. Or was that date expired. Do they need to have the second shot or can they ignore it and just let it go. Maybe you can ignore the second shot, maybe the first shot was enough. he don't want to get the second shot maybe. he don't think he should get the second shot or what you suggest do they have to have the second shot or not. Consumer stated They told them he had to speak the pharmacy and they told them another 10 days to receive the second shot and probably two weeks between the next shot, first shot and second shot that means they have another 10 days to get the second shot. Tell him something so that his anxiety (Later clarified as medical history) can go away, everybody who got the Pfizer shot, did any of them reported that they have any side effect. Consumer stated, He had a heart attack and he had a stent in his heart and he have bladder cancer and they were 'operating' for his urinating (Clarification unknown) and he had a 'scar' on his lung that's basically all. he also had a severe anxiety. he had a back problem, the pain and he have the knees problem, pain in his leg and also has the pain in his neck and this was related to the accident it's not related to the shot.
