I received my first vaccination on 3rd April: just after 2PM. I felt somewhat feverish at around 11PM, so I dosed meself up on Paracetamol and went to bed. I woke up at 10.30AM on 4th April feeling somewhat fatigued & with a slight tingling sensation in the area of my upper left arm where I'd had that injection: so after more Paracetamol I went back to bed. I woke up again at around 4PM with no trace of feverishness, tiredness or any adverse feeling in my arm. So all of that happened in little over 24 hours from syringe of Oxford AstraZeneca vaccine in my arm to full recovery. My second & final dose is at the same time on 19th June.
The vaccinations I'd received at school decades ago.
