Depende sa katawan ng tao yan since di lahat nakaka experience ng side effects. Yung step-dad ko nilagnat but yung mom ko hindi. Most common is fever na pwede mo naman inuman ng paracetamol plus bed rest. Nawawala na after a day or two. Headache and muscle pain sa area ng shot are other common side effects. Please remember these are TEMPORARY side effects for long term protection against covid. Please get your booster for the sake of your baby. If ebf ka rin pala your milk will transfer antibodies kay baby and will make him/her protected so win-win sainyong dalawa.
