The vaccine also gives one a sense of protection from infection and so they are more likely to attend mass gatherings. where the virus can be transferred.
Lowered symptoms on droplets would be better, but a lot of in-person workplaces have a "do you have a fever?" check before they issue you any sick leave.
Not having a fever and looking like a mild cold in winter would cause at least my cousin's employer to ask her to come in and wear a mask at work (manufacturing, so she wears a P100 respirator anyway).
But the WHO has been warning about this for months.
> We cannot say this clearly enough: even if you are vaccinated, continue to take precautions to prevent becoming infected yourself, and to infecting someone else who could die.
> In many countries and communities, we are concerned about a false sense of security that vaccines have ended the pandemic, and that people who are vaccinated do not need to take any other precautions.

Try not to get sick. If you do get sick, don't spread it. If you do spread it, try to spread less of it. Defense in depth.
Vaccines do not prevent contagion but reduce the chances of severe symptoms.
Also AFAIK vaccines do not lower transmission either.
