Caller mentioned his wife experienced fatigue 48 hours after the second booster shot. Caller wants to know if these will affect her wife's immune response. Caller states that the "immune system engage the vaccine causing immunity to drop" and a day or two after getting booster dose, Does her (wife) immune response drop, while pushing the immune system to make antibodies.

Caller stated they have already received their first vaccines are supposed to be going to get their second booster dose. Caller states that it is really a kind of simple question. There are a lot of people there who have had it and she has been dealing with people every day who have it. Caller stated that he knows that when they first get the vaccines, that are mrna vaccines, and in this case, would be the booster, there is a period of a day or two when the person might feel a little funk and that varies from person to person. It is engaging the immune system to build antibodies for the disease. Caller stated, his wife was concerned about the time during that period, the 3 days after the booster shot, or something like that. Asked is her immunity to Covid reduced and Is the immunity reduced for that couple of days before everything kind of comes back and she is feeling back to normal.  He stated that it is a really weird question and in so many instances, people get the booster shots and 2 or 3 days later, they test positive for Covid, It just ends up happening to some people within those first couple of days. They got their first booster, and his wife is over 60. There is that period of time where the immune system is being engaged and she might have felt a little fatigued and had a little side effect because the immune system is being engaged, to produce antibodies. During that period of time, during tomorrow or Wednesday, is she at greater risk during that time, while it puts down the immune system after taking the vaccine.
