1st Pfizer reaction v 2nd

16 replies

Just curious to how different both doses are.
I had my first yesterday (15 weeks pg) and had diarrhoea, sickness and a racing heart last night.

Would be interesting to see if second reactions are worse or better.

I’ve only had my first and was a bit tired/shivery for a few days. Someone I know had a much worse reaction for their second jab, but it’s all anecdotal. She works in a hospital and the pattern seemed to be that people who have had covid reacted more strongly to the first jab and people who hadn’t had a stronger reaction to the second jab. A friend who has had covid had a horrible reaction to the first jab (but that was AZ). It’s all speculation though. I’m hoping it won’t be too bad second time - I haven’t (knowingly) had covid.

I've had Covid and had no side effects whatsoever to the first Pfizer. Still awaiting 2nd jab. I know about 20 people that have had both Pfizer jabs and none of them had any side effects to either.

I had first in January, second in April.

#1 I had a rally sure arm for about 8 hours the following day, I couldn't lift it above shoulder height because the muscle felt so tight.
Swollen glands a week later but gone within a day.

#2 I was just ridiculously tired for about 5 days.

25 of is in my work received Pfizer and most of our experiences were the exact same.

Everyone in my family has had Pfizer. Dh was poorly with both doses - flu like symptoms, as was sil. Dm had achy arm for first and flu like symptoms for about a week after second. Dd had sore arm for first and fine for second. DB and I both had first this week and neither of us had a single side effect, wouldn't have even know we'd had it. It's completely different for each person.

ChelseaChop · 22/05/2021 09:50

I had no side effects on first dose of Pfizer

Mentioned to friend who is a Dr and she said people react much worse the second dose of Pfizer

It’s the other way around for AZ. No idea why!

Addicted2Sugar · 22/05/2021 09:53

I have had my second and had no reaction to either of them. Barely had a sore arm from the second. I did take paracetamol after both jabs as advised by a nurse friend but was fine.

PaleGreenAndBrightOrange · 22/05/2021 09:55

Just had my first Pfizer vaccine last week - no reaction at all so far, just a slightly sore arm.

Rushhomeroad · 22/05/2021 09:57

Mild headache with first, just a sore arm with the second.

RuleWithAWoodenFoot · 22/05/2021 11:31

I had no reaction whatsoever to my first - apart from a coin sized tender patch at the injection site. It lasted a day.

Second one on a Wednesday morning. Had a funny dizzy spell about 4 or 5 hours later. Extremely sore arm on Thursday, but still went swimming. By Friday I had a banging headache and felt like crap. No temp. Felt crap until about Monday. Not enough to be off work or anything though.

There was a difference in the actual injection itself though. I didn't feel the first one at all - wondered if I'd had it! Second one I felt much more obviously - that burning injection feeling. So maybe some of it was down to position of jab and injector.

I was in bed all weekend both times with a high temperature. Probably had Covid last year. Got a racing heart rate straight after jab both times, second time had to stay back at the centre because it was a proper reaction, very high blood pressure. If you are pregnant I would mention it to the doctor and get your blood pressure checked out, just to be safe. My reaction was worse the second time.

UnicornMadeOfPinkGlitter · 22/05/2021 12:00

1st just felt like I’d been punched in the arm about 12 hours after.
2nd felt ok on the day but then felt achy and tired for about 3~4 days after.

WyldStallions · 22/05/2021 12:02

1st - sore arm
2nd - sore arm, mild headache second day, sore armpit (gland?) for about 5 days.

Stilltalkstotrees · 22/05/2021 12:05

1st = sore arm for 2 days

2nd = sore arm for 4 days (slightly inflamed)

Nothing else - continued as usual, running, etc.

ILookAtTheFloor · 22/05/2021 12:06

Mine was the same both times.

Sore arm, felt a bit tired.

Beebumble2 · 22/05/2021 13:07

1st one left me tired with a headache for 24 hrs. The second one seemed fine, but 12 hrs later I woke up feeling really nauseous, very tired, but had to get up because of the nausea. Sat up for about 2hrs, when it has passed.

Interesting, thank you all. I’ve got a midwife appointment on Monday so will have bp taken then. Maybe I’ll borrow my dads bp machine for when I have my next one.

No one seems to have a reaction to this one like the AZ. My dp was shaking uncontrollably, sweating and felt awful for a few days.
