Welcome to Mayo Connect, a community of people living with a variety of conditions and diseases. We work to support one another but are not professionals, so we cannot give you medical advice.

If you read the earlier posts in this discussion, you can see that a few others have experienced this after the vaccine, or after a Covid infection and the vaccine. Part of my mission in this crazy Covid pandemic is to search out the latest science and research based information to share. At this time, this is such a new phenomenon, that there just isn't much evidence of who will have certain side effects and why.

Searching all the literature and the VAERS (Vaccine Adverse Event Reporting System) data shows there are fewer than 1000 reports of decreased hemoglobin or ferritin out of 500,000 adverse events and over 340,000,000 vaccine doses. Even if this is underreported in VAERS, you can still see this to be an extremely rare side effect. That is not to say it is not concerning, but by comparison, low hemoglobin has been known for over a year to be an effect of a Covid infection, in much greater numbers than in the vaccine.

As with all things Covid, stay tuned for further developments. As published data becomes available, I will report it here. In the meantime, you can read through this discussion to see what treatments other people are using, and speak to your provider.

If you have more questions, feel free to ask here.
