I, along with several colleagues, had the AstraZeneca (Oxford) vaccine first dose last weekend. Three of my colleagues have had two days off work due to the side effects - headaches, fluey symptoms, rashes, whereas I am only had a slight ache on my arm at the site the vaccine was delivered.
I feel very fortunate not to have experienced unpleasant side effects, and as it's now been four days since I had mine, I assume I am going to avoid them.
None of my colleagues have reported delayed symptoms so far.
