While we are with this topic, I urge everyone who has already received the 3rd shot (booster shot) to check with your local medical professional regarding the 4th shot.
For me, I had the 3rd shot about 6 months ago and I plan to receive the 4th shot in about 2 weeks.
Friendly reminder:- getting vaccinated (having at least 2 shots, having the 3rd is much better) does not mean you will not get infected. You can still be infected (so, you will still be careful to wear mask and wash hands and maintain social distance as much as possible) but the chance of developing severe symptoms (even death) is greatly reduced.
Another important thing is, if one develops a serious or critical condition, one has a higher chance of having 'Long Covid' even after recovery. Permanent side effects like headaches, reduced memory ability, easily tired...etc will be with you.
