Another article from the British press saying that Covid symptoms can easily be confused with common vaccine side effects and that people should get a covid test done to make sure they haven't caught covid. This would make sense as two of my teenage nieces had Covid in October and their only symptoms were a headache and feeling very tired. These lasted for 4 days and on the 5th day they felt much better and were fine.
