Booster side effects?

Wondering if anyone is getting any different SE from the pfizer booster?

i got the usual sore arm, but this time i'm getting some gastric nonsense going on too.. trying to decide if its a SE or a coincidence.

I had AZ for my first two and then a pfizer booster. Main side effects were nausea and tiredness but teen DS had a really ticky tummy for about a week after his pfizer jab.

I had the Pfizer booster this morning and just realised I felt a bit nauseous, so popped here to see if anyone was feeling similar.

SmallProvincial · 11/12/2021 18:57

I was not nauseous after jab 1 or 2.

Jab 1 I felt fine, but had a super sore arm.

Jab 2 my arm was pretty okay, but I felt a bit achy and feeble for a day.

Sunsetsupernova · 11/12/2021 18:58

Yes my Dad had AZ first two and then Pfizer for the booster and had a runny tummy for a few days afterwards

bozzabollix · 11/12/2021 21:05

Had AZ for vax 1 and 2, then Pfizer booster. Felt a bit hot, cold and shivery for a night and a little under the weather for a couple of days. Sore arm but nothing major.

GoinSouth · 11/12/2021 23:56

AZ first two, Moderna third and have not felt well for a week now. Flu symptoms for 3-4 days (not consecutively), nausea one day, felt ok one day and now, a week later I'm back to having achy flu symptoms and just about had enough.

BrightonOrLancaster · 11/12/2021 23:57

I have a really sore armpit which is a first!

Nospringchix · 12/12/2021 00:01

Had AZ first two and was fine. Moderna booster and not well for a week. Tired, sore joints and bad stomach.

PanicPrevention · 12/12/2021 00:44

Armpit is probably a swollen lymph node.
Ive had swollen lymph node on my collar bone since a couple of days after my second jab about a month ago.
Not uncommon side effect from what I could find online.

@PanicPrevention
Your name suits you! I've taken paracetamol but should I take ibuprofen? I dont actually know what the difference really is between the two 🤔

FinallyHere · 12/12/2021 01:45

AZ fir first and second, Moderna booster.

No reaction at all from any of them.

Tealightsandd · 12/12/2021 01:49

AZ first two, Pfizer booster. Flu type side effects after first, nothing but slight ache in arm (for one day) after the others.

If your symptoms go on longer than a couple of days, it might be worth getting a Covid test. It can cause gastric issues, and it's very possible that you caught it shortly before your vaccine.

Hope you feel better soon.

Have had three Pfizer shots, nothing after any of them except sore arm

Elsalvador · 12/12/2021 03:24

Pfizer 1st and 2nd jab - sore arm nothing more.

Booster - Pfizer. Sore arm but for the rest of the day, felt a bit achy as if I was coming down with the flu but fine by morning.

Only difference is that my booster was a walk in so I hadn't prepared by drinking fluids and making sure I was well hydrated as I did with jab 1 and 2.

HangingDitch · 12/12/2021 03:58

First two jabs were AZ. Had a sore arm for about 4-5 days afterwards. No other side effects.

Had booster at the end of last week, Pfizer. No side effects at all except for a slightly sore arm on the day.

wandawaves · 12/12/2021 04:36

All 3 Pfizer here. 1 and 2, no problems at all.
#3, nausea, drop in BP and associated almost fainting for 24 hours, mild temp.

sylv165 · 12/12/2021 04:54

AZ for first two jabs, no side effects other than a sore arm. Had my Pfizer booster yesterday morning and am now lying awake with a temp, shivering and feeling quite nauseous. Hopefully it'll pass soon 🤞

They are both painkillers but they work in different ways. Paracetamol has an additional effect of bringing down temperatures, whereas ibuprofen is an anti-inflammatory so will reduce the effect of swelling if there is any.
Lymph glands do swell as a result of vaccination or infection (as they contain more white blood cells to fight off the infection) so ibuprofen can be used to reduce this, but it's a natural part of the immune response.

HeronLanyon · 12/12/2021 05:35

I had no side effects other than sore arm and even that only for half a day. No effects from first two jabs either here though

ChangingStates · 12/12/2021 06:01

Pfizer booster yesterday afternoon, woken up with a bit of an achey arm, nothing else (yet)

Wallywobbles · 12/12/2021 06:02

First 2 Pfizer no effect. 3rd Moderna felt grim for 2 days.

WhoWants2Know · 12/12/2021 06:49

I had 2 AZ and spent the day in bed after the first. Moderna yesterday and so far just feeling weak and don't want to move.

Youngatheart00 · 12/12/2021 07:08

Mega achy arm after Pfizer booster Friday - it’s still sore now hence me being awake at this time on a Sunday when I really should be snoozing!

Not had any gastric symptoms

RedElephants · 12/12/2021 07:11

AZ first to jabs, 2 jab sore very uncomfortable arm for nearly 3 weeks! And took 2 days off work.
Had booster yesterday lunchtime, Moderna, arm sore, feel a bit achy, hopefully that'll be it..
