Vaccinated people can still catch, carry, and communicate COVID to others... and if you got vaccinated before the summer, your antibody levels are probably not as high as you think. Vaccination is not a binary thing, in terms of how it actually works. If an unvaccinated person catches COVID from you, it doesn't matter whether or not you (the carrier) were vaccinated... The virus that ravages and possibly kills your subsequent victim is just as dangerous to the unvaccinated.
