Moderna booster.

    Got my moderna booster yesterday and I'm absolutely floored today. Feels like the flu I'll probably have to leave work early I cant concentrate. My original jabs were Pfizer. Has anyone else had this experience?

    I was in receipt of the Moderna booster after Pfizer vaccines.

    i had zero side effects after the Pfizer shots but I was reasonably fatigued for 24 hours following the Moderna booster.. exact same feeling as jetlag…no flu symptoms aside from being tired and lethargic…

    Got Moderna yesterday about 4PM. Felt like a medium hangover earlier, but that's abated with a bit of Nuerofen. Was always the following evening on the previous jabs when I felt poorly, so maybe it's yet to come...

    Went to a pharmacy that had walk-in booster shots on Friday, because I had to pick up my daughter on Saturday at university in Washington, DC and her roommate had a 104.1 degree Fahrenheit fever and tested positive for Covid. My original two shots were Moderma as was the booster. Daughter tested negative for Covid on Friday. My arm only hurt, no bad effects and I was driving for 8 hours on Saturday.

    You can ignorantly accuse me of "whataboutism," but what it really is involves identifying similar scenarios in order to see if it holds up when the shoe is on the other foot!

    Same as you OP. About 48 hours of flu-like symptoms with mild fever and fatigue.

    I have heard 2 people complaining about swollen glands and fatigue after Moderna.

    Also had Moderna booster after previously having Pfizer. Had my on Saturday morning and arm is still sore today. I was very lethargic yesterday also but started to get better towards the evening.

    Feel fine today other than the sore arm

    The MVCs are using Moderna as booster. GPs and pharmacies seem to have Pfizer for boosters.

    I read something to the effect that there are large stocks of Moderna to use up? Wonder if the MVCs will switch to Pfizer soon?

    First dose: moderna, sore arm

    Second dose: moderna, sore arm

    Booster: moderna, sore arm

  • Registered Users Posts: 4,962 ✭✭✭ Cluedo Monopoly

    The MVCs had 1 million+ doses of stock in early December. It will be a while before they revert back to Pfizer. You're right, the GPs/Chemists seem to be still using Pfizer.

    Will most likely be getting Pfizer for the booster from my GP after initially getting Moderna. Would prefer to get Moderna for the booster as well tbh. It's effectiveness seems to last longer than the Pfizer vaccine.

    Go to a MVC then. Plenty spikevax in all of them.

    Got Moderna booster yesterday. Bit of a sore arm is all. Same as when I got the Pfizer shots originally.

  • Registered Users Posts: 316 ✭✭ Psychedelic Hedgehog

    Had a Moderna booster the week before last, on top of a double Pfizer initial vaccination. Sore arm for 2 days or so, and extreme tiredness from about 24 hours after the jab for another 24 hours. Fine after that.

    Got Moderna yesterday evening. Not 100% today but I can live it it if it doesn't get any worse. I'm tired and a bit shivery.

  • Registered Users Posts: 6,431 ✭✭✭ CrowdedHouse

    Moderna last Tuesday

    1st dose Astra - slightly sore arm for maybe 4 days

    2nd dose Astra - slightly sore gone in less than 24 hrs

    Last Tues Moderna - sore like I got a belt of a hammer in the arm. Soreness woke me up during the night (I may have rolled over on it). Slight headache and felt freezing cold Wednesday. Actual soreness faded but a pain in my arm if I lifted it above horizontal. Pain eased Thursday, all clear Friday.

    Had Moderna booster on Thursday lunchtime. Had a very painful arm, shivers, fatigue by late on Thursday; Friday & Saturday the same, with muscle & joint aches, and glands swollen in my armpit as well. Also had some mild palpitations on Saturday evening (around 25-30 beats faster than usual resting heart rate so nothing dramatic like 150+ HR, but could still feel it). Today, Monday, my arm is a teeny bit painful still.

    I had Pfizer for my first two doses and had NOTHING like this, aside from the sore arm which was gone by the end of the next day. Booster really floored me. Still glad to have got it though!
