Vaccination prevents severe illness.
Detailed Answer:
Hello and welcome to the "Ask a Doctor" service.
I have read your question.
1. Until now we know that people vaccinated previously can experience a less severe disease after COVID-19 infection, so, it is possible for your mother to be protected to a certain degree after being vaccinated.
2. Omicron variant may increase brain hemorrhage, but only in cases of severe illness.
3. Besides supplements, is necessary a close follow-up for neurological signs and other parameters such as normal blood pressure, normal levels of blood oxygenation, etc.
In conclusion, since your mother resulted positive and is experiencing minor signs of the disease, chances are to pass this infection without any major health issues.
Hope you found the answer helpful.
