Vaccine Side Effects - What side effects did you get from your vaccine?



  • Registered Users Posts: 172 ✭✭ blackbird86

    Had Pfizer, first dose I didn't even feel the injection. Had a mildly sore arm that night/next day. Was gone within 24 hours & wasn't bothersome.

    Had my second dose on Monday I found the injection very sore & my arm was immediately throbbing. It eased to a manageable level of soreness a while later. Woke during the night & yesterday morning feeling awful. Really bad nausea all day & just felt really unwell. Went to sleep mid afternoon & started to improve after that. I still feel tired today but otherwise feeling well again thankfully

    Pfizer Jab

    First Jab-sore arm, headache,

    Second Jab-slightly sore arm, extreme tiredness that night. Fine next day

  • Registered Users Posts: 2,126 ✭✭✭ recyclops

    Pzifer jab on Friday, didn't sleep well at all since then until last night, woke up this morning and felt great.

    First jab was just sore arm so didnt expect this at all. Even though I didnt sleep well I wasnt overly tired during the day oddly

  • Registered Users Posts: 848 ✭✭✭ Drummerboy2

    First Jab ASTRA Z, slightly sore arm, woke during the night with temperature and saturated. Fine following morning when I awoke.

    Second Jab, no issues whatsoever.

    For context. Most comments here will be the one in ten people who get side effects. Not those who were perfectly fine after it which is the vast majority people I know who have got it.

    Well turns out after a day at the hospital, it's appendicitis. So was a good idea to get it checked out. Surgery tonight hopefully. They did a quick pcr test there. Would the vaccine lead me to test positive? I'm not sure how similar to the covid virus the vaccine looks. Can the pcr test confuse the two or is that a stupid question?

    The vaccine will not cause you to test positive.

  • Registered Users Posts: 1,439 ✭✭✭ italodisco

    Had 2nd pfizer jab last week, omg my legs were killing me all night long, felt like I had been squatting and doing walking lunges all week!

    Another strange thing was a constant erection (sorry for sounding rude) from around 10pm until around 4pm the following day. I even rang the gp about it and her advice was it's not a known symptom and it should go away, if it doesn't then ring her back lol.

  • Registered Users Posts: 1,578 ✭✭✭ eggy81

    I’ve had tinnitus for about 4 weeks now. Not sure if it started before first dose or after. That and still manically tired and feeble feeling a full 2 weeks after second jab.

  • Registered Users Posts: 15,041 ✭✭✭✭ Galwayguy35


    After the first shot just a sore arm but after the second one had the sweats, headache and no energy.

    Was fine by evening time the next day.

  • Registered Users Posts: 1,439 ✭✭✭ italodisco

    I hope the tinnitus goes away, I've had intermittent tinnitus for 4 years now and when it's bad it's soul destroying, high frequency ring in one ear, drives me up the wall at times. Get it checked

  • Moderators, Business & Finance Moderators, Motoring & Transport Moderators, Society & Culture Moderators Posts: 62,543 Mod ✭✭✭✭ L1011

    Nothing further. Been quite lucky with very little from either

  • Registered Users Posts: 31,702 ✭✭✭✭ Mars Bar

    Full time tinnitus sufferer here. It's nasty. Would definitely wish it on my worst enemy.

  • Registered Users Posts: 1,439 ✭✭✭ italodisco

    I go through periods of it, might not have it for a week and then it comes on, can't concentrate on much when it's bad.

    Mine comes on after I carry anything heavy or use my left arm for leaning on, carrying things with my left, push ups, arm curls etc (just my left ear rings) and a gp is sending me to a shoulder specialist as she is convinced its a pinched nerve.

    Here's hoping!

    Pfizer here, early 40s, good health.

    Dose 1 - sore arm

    Dose 2 on Thursday 22 July - sore arm and I’ve been really tired the last couple of weeks with slight headaches coming and going.

    Right now I don’t feel good at all about getting a booster and if I had a choice today I’d say no.

    Got my first Pfizer a week ago. Had no side effects on the day*, and he following day I felt like someone punched me in the arm. Was sore if it touched against anything, but it didn't swell up, or become immovable or stiff or anything like that. Just a day of a slight soreness that went away the next day.

    *About 5 minutes after getting injected, I got a really hot flush and a fainting sensation, lasting about 3-4 minutes; but this seems to happen me anytime I've ever given a blood test so i think it's just my body doesn't like needles!

    Likewise , started about a week or so after my 2nd Moderna shot.

    I've had it a few times before but only for very short periods of a couple of days at a time - It's been going for for about a month now though.

    I have a history of Sinusitis so not sure if it's just coincidence that this came up after the shot.

    I had a sore arm for a day or two after the 1st shot however after the second shot it was sore again but this time the area around the injection site was hot to the touch for about a week , similar to the way you might be after a reaction to an insect bite.

    Also - I actually caught Covid between the 2 shots , tested positive 8 days after the 1st shot as a close contact of another positive case. so my second shot was delayed by about 10 days as they insist of a full 28 days after a positive test before you can get it.

    I only had ~1 day of symptoms from Covid - about 2 days after I tested I woke up with a 104 temp and a very painful cough and generally felt wretched for 24/36hrs , was fine after that though.

    Pfizer here

    After the first I had a sore arm for a couple of days, tiredness the evening of and two nights of bad sleep.

    After the 2nd sore arm but not as bad as the 1st time and a headache and tiredness next day but not sure if that was because of the vaccine or the fact that my 1 year old kept me awake half the night.

  • Registered Users Posts: 3,406 ✭✭✭ Polar101


    1st jab - sore arm, and headache/nausea on day 2 (felt like a bad hangover, but didn't last long)

    2nd jab - sore arm, but no other side effects

  • Registered Users Posts: 3,062 ✭✭✭ questionmark?

    I think you took the wrong Pfizer!

    Joking aside....that is a very unfortunate side effect and first time I heard anyone say it.

  • Registered Users Posts: 1,008 ✭✭✭ 1123heavy

    Had the Janssen yesterday

    Fine after it until about midnight last night felt a fever coming on. Temperature at 40 all day and feeling like I was hit by a train, moderate fever.

    Took some paracetamol and had a good snooze in the afternoon, felt a lot better but still not fully there. Tomorrow should be a lot better hopefully.

    My opinion is the same. I half joke that I am keeping a list of all the public figures who became despots at this time.

  • Registered Users Posts: 22,221 ✭✭✭✭

    Read up a bit yesterday on Covid vaccine side effects and side effects for vaccines generally and the concensus seems to be you should have side effects, you should have the sore arm, you should experience other things as well to varying extent. That that is good and it means the vaccine is working through and doing what's it's suppose to.

    Got my first pfizer 2 weeks ago and only side effects I had initially were a sore arm and mild fatigue. However the last few days I've been getting severe night sweats. No fever that I can tell, but massively profuse sweating to the point my bed sheets are soaked.

    Wasn't sure if it was related to the jab or not (especially given it started maybe a week to 10 days after the jab) but found a pre-print of a paper that reported night sweats and hyperhidrosis as newly reported reactions. ( Also reported by the EMA (

    Cake, and grief counseling, will be available at the conclusion of the test

    Not sure if it's just me or maybe pure coincidence but can help thinking my immune system is doing it's job after both doses.

    Anyway here it goes, I usually sleep absolutely fine. Just over 2 weeks from dose 1 I got 2 nights in a row where I found it hard to sleep until around 2am or there abouts when I'd eventually drift off to sleep. 2 nights in a row and then it didn't happen again.

    Fast forward 2 weeks after 2nd dose and I've had 3 nights in a row of the same thing, going to bed at the same time as usual and then not actually getting to sleep until around the 2am mark.

    Now maybe it's just me but I can't help but thinking that my immune system is doing it's job and kicking in. Anyway could be completely unrelated but just got me thinking with regards to the time from jab to immune response etc
