Post covid vaccine adverse effects are quite common in individuals.So no need to worry.

This can happen after vaccination. salt water gargling and crocin if needed.  If not better after 2 days, need to evaluate

No need to worry

Side effects after vaccination may last for 1 to 2 days and this is normal, no need to worry Any symptoms after 4 to 5 should raise a concern

It would be good to evaluate if i can get more history

Yes little concern for self and others is what needed. First of all isolate yourself and start using medication after proper consultation. Because unmasking of covid in vaccinated individuals is common as it is observed that with vaccination body immunity briefly comes down this is where people gets duped. They think after vaccination they are immune to covid. This misconception is spooling the game. Be aware wear mask and maintain all precautions.
