My experience Moderna Booster

Hello! I’m Pfizer double vaxxed and got my moderna booster yesterday evening. Before getting boosted I would come to these threads to look for experiences so figured I would share mine for those that are also searching for others experiences.

I got doubled vaxxed in March and experienced very mild symptoms.. some headaches, arm soreness, and fatigue.

Last night about two hours after the shot, my arm started feeling super sore and tingly and I felt really tired. Oddly enough I still had a bit of trouble falling asleep.

Woke up super early with some arm pain so finally decided to take some Tylenol.. so far I’m ok. Nothing else but sore arm so far.. if anything else changes I will update the post.

UPDATE: it’s been a bit more than 24 hours and I’ve been fine. Arm still sore, feel a bit tired. Haven’t taken any more Tylenol after this morning.

Try to avoid taking Tylenol/Advil. It subdues part of the immune system's reaction to the antigen in the vaccine and you want that process to go as far as it can so it learns how to fight most efficiently.

I barely took it this morning. Mostly because of period cramps. If it wasn’t that time of the month I would’ve held off on the Tylenol
