I had the Pfizer booster 10 days ago. I had 2 doses of AZ before. I've been very very tired the past week, more trips to the loo, and my heart rate is higher - average 85, though it's usually about 72. It's reminiscent of being hyperactive decades ago.
Could the booster have affected my thyroid levels? Thinking I could reduce my T3 to see if that helps. I've been stable on T4 and T3 for 5 years up to now, usually 100T4 and 25/30 T3.
I reckon i 'd wait a bit longer see if it settles down on its own ?Could well have ben coincidence , but 10 days after i had pfizer (sept) i got pretty spectacular spontanious bleeding into my thumb .. and a very odd feeling in arm/ hand/ fingers... bit alarming at the time , but no repeat problems since then .
Mmm.. The tiredness could be the booster, though it's got worse after the first week. Almost too much of a coincidence.
I'm dropping 5mcg T3 from today for a few days and see what happen.
I had the booster or 3rd jab as they also call it… confusing, last Friday and I have been feeling exhausted and sleep throughout the day. I felt lightheaded also yesterday top of my arm where I had the jab was itchy so scratched it , naturally became red and did swell up. Better today from the swelling point of view but the tiredness.
JGBH, 'the booster or 3rd jab as they also call it… confusing,'
No, the third jab and the booster are not the same thing.
This third dose should be offered to people over 12 who were severely immunosuppressed at the time of their first or second dose, including those with leukaemia, advanced HIV and recent organ transplants. These people may not mount a full response to vaccination and therefore may be less protected than the wider population.
This offer is separate to any potential booster programme.
gov.uk/government/news/jcvi...
The rest of us just get a booster.
When I asked the difference from the nurse who did it (and there was also a pharmacist present because it was done at my local pharmacy last Friday) they both said it was The Same….. So who to believe? I had the jab because I was sent a txt message because I have autoimmune diseases so immunosuppressed AND having immunosuppressant biologic injections on a weekly basis plus taking steroids. I was told that the NHS would get in touch with me later for a booster!! So hence the confusion. Does this make any sense to you?
Yes, if you are immunosuppressed, you will have three jabs and a booster. The rest of us just get two jabs and a booster. 
Thanks, I get your point but both the nurse and pharmacist didn’t really seem to know…. They were hesitant in their replies…
They need to read the government press release that I quoted from above! gov.uk/government/news/jcvi...
However, if they don't know your personal medical situation, I suppose they wouldn't necessarily know if they were giving you a third jab or a booster.
Well, it was at my local pharmacy next to the surgery and they always work together so that’s interesting… chaotic somehow! I had to tell them my health issues and treatment, so they didn’t seem to know. Not great. Furthermore, friends of mine who are in my age group (living in a different area from me) but are not immunosuppressed were given a booster! That’s exactly what they were told at the time, very odd. So anyone can see this isn’t really organised otherwise this sort of thing wouldn’t happen. However…

They are two different things.
There is a third vaccine for immunosuppressed people, they have 3 vaccines followed by a booster.
Everyone else has two vaccines followed by a booster.

Thanks. Yes have completed the poll adding comments.
Hi there. This has also been confusing me. When the pandemic started I received a letter saying people like me on immunosuppressant drugs Were immunocompromised and I should keep a hospital bag packed and take care shielding. They then listed the drugs they were worried about but mine (sulfasalazine) was not listed so I did not pack a bag! Then just before I had my booster I got a letter saying I needed to book a third jab as I was on immunosuppressant drugs, but again mine was not listed. So, at the surgery for my booster I showed the doctor the letter and he said this booster was the same thing as a third jab and as I was on sulfasalazine I need not have been sent the letter. Most odd.
I suppose it's possible, and it could be that it affects some people not others. I imagine it would be a temporary thing but I don't really know. I've having my booster in a couple of hours time. I had AZ for the first two jabs and having Pfizer for the booster. It will be interesting to see if I react to this one, I had no reaction at all to the others.
Hope all goes well!
I had no reaction to the AZ. Had Pfizer on Wednesday and joint pain for 24 hours afterwards

Will do. Wanted to wait to see how long it lasted
I had tiredness and a sore arm the first day after the AZ and the booster. But this tiredness and higher heartrate is a week after the booster. Odd
TaraJR,
Observations and experiences like yours will be really helpful and visible to others if posted on our dedicated Booster poll thread here, please healthunlocked.com/thyroidu...
Suggest you consider reporting to doc and, arguably more importantly, complete an MHRA yellow card as that's what its for. Cade83 also reported increased heart rate after vaccine yesterday.
I've had a similar reaction. Feeling hyper. I reduced t3 a little and it has helped. But then tried to increase back to where I was and felt hyper again. Its been 8 days since I had the booster. I'm not sure how I'm going to feel in a few days on a lower dose. Having to play it by ear
I had the two AZ jabs and then Pfizer booster. After four days of a fast pulse, I saw the gp. My bp was high as well. Ended up on meds to lower bp and slow heart rate. I had one ecg that was ok and will be having a 24hr ecg in the next week or two. I looked online and it recommended that if you had an increased pulse that starts four days after the Pfizer jab, seek medical attention .
This is interesting as I had my first Pfizer vaccine in January and have had ongoing problems since I also had my second in April. I have had palpatations sweating rash nausea fatigue ect. My medication had been decreased and increased since this time. I have wondered if it could be related to Pfizer but it is early days with regard to patient feedback.I have had numerous GP phone consultations and referred to gasto and ent as I developed Tiñnitus in left ear nothing sinister showed up.
I have not had my 3 vaccine yet but I will be getting it soon.
I have had no explanation of why I had all these symptoms start at the same time I have thought it could be related to Pfizer vaccine setting off over active response.
I also have rheumatoid arthritis I take biological drugs for that and metherexate
It is quite a combination and who knows if in some people the vaccine could cause these symptoms. I just hope mine settle down and yours too

Are you immunocompromised? If so you will have a 3rd vaccine followed by a booster. If not you will be having a booster not a 3rd vaccine. They are two different things.
Yes I am immunocompromised . I have been invited for a 3rd vaccine and a follow up booster in 6 months
I have been on medication to suppress my immune system for 24 years for the treatment of Rheumatoid Arthritis.
This is not a spoof question; if you had ongoing problems since your second jab, why are you getting a third one? I am interested to know. This would also apply to those who had bad reactions to their first and then continued with more.
Because there is no definitive evidence that the vaccine caused the symptoms.I have a number of autoimmune conditions and the risk of catching covid and being very ill still outweighs the on going symptoms.
Thank you for your reply and explanation.
I think it is a difficult decision to make but until they have more information about the possible affects of the vaccine on certain groups of people I am airing on the side of caution and having the vaccine. In the past I have been very ill with pleurisy and I know how getting any illness or infection affects me.
I too had the two AZ jabs then had the Pfizer booster 11 days ago. Sore arm for first 4 days, then since then have had extreme exhaustion and intermittent joint pain. I have completed the survey as quoted above. My elderly mother, also hypothyroid, had the same reaction, with additional bright yellow diarrhoea.
Could it not just be your bodies immune response to the vaccine? Being given a jab puts the body under allot of strain, its likely nothing to do with your thyroid or t4 treatment. I think its sensible to ride this out, and leave your treatment alone. If it continues speak to your GP.
This is interesting. I had 2 doses of Pfizer, last in April so considering booster next month. I do recall feeling very “off” for a few weeks, like I was hyper - anxious, faster heart rate, higher BP, etc. It was concerning enough that I remember thinking I would probably pass on any boosters that came along in the future. Your post has reminded me of all this. Decisions decisions….ugh. Hope you feel better soon.
I wondered this. First Pfizer, no significant change. Second Pfizer, extreme fatigue followed by hyper stage for few weeks before return to hypo. Third Pfizer (asked vaccinator what dose booster was and was told identical to first two), fatigue for almost two weeks now currently feels like I'm in an extended hyper phase (from quite hypo). Have had to temporarily reduce my meds as totally wired and not sleeping. Assume I'll revert to hypo soon so carefully monitoring as best I can. Confusing.
Thyroid17, my first two doses were both Pfizer and you described me to a T after the 1st and 2nd. Unfortunately, I lowered my NDT dose for a few weeks after the 2nd because I felt so hyper, but since then I'm having a hard time getting back to wellness. I'm even on a higher dose NDT now. It is enough to make me wait much, much longer to get the booster.
I did have trouble deciding before my booster, it is such a personal decision. I finally although nervously decided to go for it as two of my colleagues had been ventilated with only one pulling through (early on in pandemic). I completely understand as I am still hesitant about any possible future ones, I suppose it depends on how this hyper stage pans out and what follows. I have temporarily halved my dose to rid myself of this wired feeling and hope for good sleep but am watchful for any warning of an impending dip.
