Covid booster and flu vaccination

I had both the winter covid booster and ‘flu vaccinations at the same time together on 20th September and starting 4 or 5 days later my glucose levels have increased significantly. I was diagnosed T2 in 2017 and relied on diet and exercise which have worked up to now with morning readings around 5 and bedtime readings around 7. The only thing that I can see to cause my consistently out-of-range readings is the possibility of a reaction to having the 2 jabs together. Has anyone else noticed anything similar? I cannot recall such a reaction after previous single jabs.
I have raised my concern with my GP and as a result will have blood tests later this week including A1c that was 48 in May this year.
 
I had both mine yesterday as did hubby who isn’t diabetic, we both had aches in arms and across back of neck and shoulders, we were both very very tired last night, fine today apart from usual ache in arms from jabs, my bs seem fine but I am keeping an eye on them over the next few days. For me personally a few slightly elevated bs are a small price to pay for the jabs, I’m sure if they do rise it will only be for a few days and not by much. How much have your numbers raised? What numbers are you getting when testing? Of course it could have nothing to do with the jabs and maybe you are sickening for something. Good your GP is looking into it
 
I had both of mine last Wednesday and it had no affect on my BG at all.
 
I also had the usual soreness around the vaccination sites and was very tired for a couple of days both of which I was prepared for. Last night’s reading was 9.0 and this morning’s was 8.3.
I may be making a mountain out of a molehill and everyone reacts differently but I hope that this is is only a temporary blip - not an ongoing problem that cannot be solved by diet alone.
 
I would research the latest facts around this matter. Not conspiracy theories just hard facts. It is interesting that things that were banned on YouTube (within their terms and conditions) have been quietly dropped about what can be said. We advised my son in his early 30's and our daughters both under 20 and I am delighted with the choices they independently made.
 
It is known that having a booster takes down your immune system for 2 weeks after the dose therefore I suggest you've acquired a virus or infection, a classic symptom of which is elevated blood sugars. Hopefully whatever this is will be mild and be dealt with by your natural immune system.
I don't know about the flu jab but do know this is the case for covid vaccines/boosters based on the morbidity spike in each of the demographics as they received their jabs through 2021.
 
In earlier rounds of vaccines it was widely reported that glucose levels were often mildly affected for a short time. Mostly slightly raised but a few saw drops. A vaccination is designed to provoke an immune reaction. When we have an immune reaction going on in our body (usually on exposure to an illness/infection etc) we are designed as humans to respond and one of those responses is raised glucose levels. Presumably to give us more energy to fight the bug.

So by all means get things checked and keep an eye on it but I wouldn’t worry over it just yet as the worry itself will raise levels too.

can you provide a link to this? I certainly have heard It takes a few weeks to become effective? I can only assume if it is actually the case then it’s because the immune system is busy reacting to the vaccine as it should making antibodies etc and thus less able to deal with another challenge. Much the same as if you have one bug you are more susceptible to another.
 
Thanks Nicole. Will see what my blood test shows.
 
Thanks for your response and the useful links.
 
I had both jabs (Covid jab was Moderna rather than the previous Pfizers) on Saturday, one in each arm.

One arm felt VERY slightly stiff on Sunday and I was just about aware of a minute jab area "feeling" . So nothing different really from previous jabs, though my pre and post glucose levels were definitely and consistently up by 1-2 points for about 24 hours but are more or less normal again now. However I'm also currently on regular painkillers for arthritic pain so this will presumably be affecting things too.

As far as I can remember I've only had one longer mildlish reaction to the Covid jabs
 
Earlier I expressed my concern over raised blood sugar levels following both flu and covid booster jabs at the same time. I have now had the blood test results with some raised white cell counts and Alc 50 which is up from 48 in May. I have been keeping a detailed food diary since end September and a note of blood glucose levels on getting up and last thing at night. Where before the jabs my readings in the morning were averaging around 5-6 and night around 7-8, they are still around 8-10 or higher at night and nearly 8 in the mornings. I am still hoping that this is a temporary reaction to these jabs and that diet monitoring will suffice.
 
I recently got both jabs in the same arm in the same week. My bgl levels shot up significantly for the next few days, but last night I had my first hypo in over a year. So I seem to be recovering I had no side effects at all from either jab apart from a very slight tenderness at the injection site. The WBC increasing is to be expected for a while as the antibodies are mustered, but that will dissipate.

Thanks for your info on the double jab. I am about to do mine next week, and was wondering if there were any issues.
 
I just had the Covid one on Friday ( all 4 of mine have been Pfizer). 24 hours of higher temperature and general unwellness, then fine. Not had the flu one yet, I refuse to have 2 together, due to bad experiences in the past.
 
I had my flu and Moderna Spikevax boosters on the same day (in the same arm). I flew to USA the next day and then worked 5 straight 15 hour days. I was tired but I put that down to the work rather than the jabs. My blood sugars were no different to what I would expect from such a timetable.
I am not some super human being or a young 'un.
 
There are a number of research papers showing that the covid vaccination can cause people to develop diabetes or to transition from type 2 to possibly type 1 or 1.5. However, incidence seems to be very rare and most people will only see an increase over a few days as the result of a normal immune response to the vaccine.
Sadly, something has gone wrong for me, and six weeks after the vaccine I am getting results between 13 and 23 mmol. I am awaiting a scan and pushing for tests to reassess my diabetes type. Ketones have been raised but not to the dangerous level. I'm just writing this in case anyone else has a similar experience.
 
I was diagnosed T1D last October shortly after my 2nd vaccine jab. Aged 44 at the time and no family history of diabetes I wondered if the vaccine had triggered my diabetes as within days of the jab I suffered from symptoms of what I now know to be diabetes - thirsty, weight loss etc - my vaccine nurse was not concerned at the time and neither was my doctor until my weight was monitored over 5 - 6 weeks. Eventually a blood test was done and I was admitted to hospital for 4 days which resulted in my diagnosis of T1D. Neither nurses or Doctors were bothered about my concern that the vaccine may have been a trigger and this has me worried about whether to accept my invitation for a further vaccine jab a year later?
I appreciate that the vaccine has prevented illness and death around the world, but I'm worried that my questioning of my illness has been dismissed as nothing to worry about and that I could have developed T1D at anytime in life.
To further give me cause for concern I was diagnosed with DVT in September this year and am having to take blood thinners for the next 6 months - I don't smoke and my diet is low fat, yet despite living a healthy lifestyle doctors dismissed my concerns again and sent me on my way.
Does anybody in the medical profession take note of unusual side effects or changes in peoples health after having the vaccine? I have found monitoring my blood glucose and taking my insulin stressful over the past year, but fortunately hadn't needed to make any dietary changes but worry about further vaccines for covid as I have not had my questions answered satisfactorily.
 
The doctors just say "I doubt it was the vaccine" if you develop issues after having it. My dad had tingles in his arm after having his and he kept saying to the doctor about it but being ignored. Soon after that he had a stroke. It was the astrazenica one he had. I also worked in care for almost 10 years and when the elderly were having their first jabs we lost 11 strokes and heart attacks mainly. They were dropping like flies and I've never ever known so many to die within 3 months. We usually lost 1 or 2 but never 11! I raised concerns but was ignored.
