Abstract
A group of participants, all of whom were previously infected with the coronavirus, and now visited the hospital for vaccination, and we separated two groups, the first group to use nothing and the second group to use supplements. In the future, we will find differences between the two groups in terms of immunity and side effects to the vaccine
