I would also like to know. Please elaborate for us as we make this difficult decision about the possible exacerbation of our long COVID symptoms, by taking the new booster.

@greenshade & @bestseller2025 - I was able to find one study of people with long-Covid, that spanned 24 months and addressed this issue, I'm sure there are more but time prevents me from looking further.
Here was what it said: "Impact of COVID-19 vaccination on long COVID symptom persistence
Out of 121 patients, 113 were confirmed to be fully vaccinated against COVID-19 by the 24-month timepoint following COVID-19 infection (eight patients were never vaccinated). All vaccinated patients received at least two doses. At 24 months, comparison between vaccinated and unvaccinated patients revealed no significant difference in major neuropsychiatric symptoms of long COVID (Table 2). For vaccinated patients, there was no significant difference in the frequency of major neuropsychiatric symptoms between patients who received fewer than three vaccine doses and those who received three or more (Table 3). Repeating this analysis with the unvaccinated patients included, there was still no significant difference in neuropsychiatric symptom frequency between patients who had received fewer or more than three vaccine doses."

If you would like to search further, you can go to scholar.google.com and enter this phrase "covid vaccine if you have long covid" Set the search parameters to Articles since 2024 to get the most up-to-date information.

If anyone finds addition info from a complete study, please post it here.

@greenshade and @bestseller2025, in addition to the study that @sueinmn shared, you might be interested in this related discussion started by @annies444

It is clear that you want to do the best for your health.

Bottom line: As with most health issues, everyone is different. You are wise to discuss the pros and cons of vaccination with your doctor who knows your medical history and current health status.

@greenshade I did not take the vaccine the first go around. I have had long COVID for 3 years now. I have never had a flu vaccine and never had the flu that I remember. I have seen so many different people say that they still got Long COVID, even with the vaccine. There may be (pretty sure) that there is research on people that got Long COVID who were vaccinated and those who got it that were NOT vaccinated. I have heard both. At this point in time, I really do not trust the FDA or Big Pharma. That is only my view. There are probably research papers, make sure they are peer-reviewed. Let me know what you find if you undertake this. I have yet to get over this illness.
