Oxford/AstraZeneca Jab

Two days ago, I had the Oxford AstraZeneca jab. It was fairly painless and have had minimal tenderness throughout the past 48 hours. That evening, I did get the chills and spent most of the night with a heightened temperature - a comparatively toasty 37.5C. The following day, I could've sworn that my head and neck had been placed by a full-on Moai head and I broke out in a racid yak sweat, which was uncomfortable. Today, I feel a lot better with only cold-like symptoms and residual tiredness.
To think this is nothing like the full blown Covid symptoms. Onward to the next one, whenever.
