Vaccination = Warning!!!

Vaccinating somebody is like installing new software in your computer. It is long lasting and it will create specific antibodies which will take over your own non specific/broad antibodies.
The dangerous part is that when the virus mutates you have no natural broad antibodies to fight the new strain of virus
YOU WILL BE LEFT EXPOSED AND UNPROTECTED.
This explains why vaccinated people will still get COVID and be even more at risk of developing serious complications.
