Hai! Selsema dan sakit tekak lepas vaccination memang common, especially dalam few days after, kena immune response dia lah. A few of my mum friends experienced something similar after their jabs and most recovered within 3-5 days with rest, lots of fluids, paracetamol, and gargling dengan warm salt water (membantu jugak untuk sakit tekak). If it persists or gets worse, or kalau ada fever yang tinggi, better check with your doctor or clinic to make sure it's not something else lah!
