COVID-19 and Immune-Mediated RBC Destruction. A growing number of studies now suggest that people with this painful genetic blood disorder who also are infected with SARS-CoV-2, the virus that causes COVID-19 disease, are more vulnerable to severe health complications than the rest of the population. Heavy alcohol drinking is known to further aggravate anemia. He began feeling more tired over the next two months. It may also lead to problems during recovery as well. No internal bleeding was found. He was admitted to our hospital due to progressive pancytopenia (Supplementary Table 1). Age Based on hearing this question a second time, I dove into everything I could find about vaccines and iron deficiency there just is no data, anywhere to suggest a link. Two messenger RNA (mRNA)-based vaccines that lead to transient expression of the SARS-CoV-2 spike protein are highly efficacious in preventing severe infection.6,7 Reactions to these vaccines are generally mild; however, increased complement amplification could theoretically lead to more severe effects in diseases like paroxysmal nocturnal hemoglobinuria (PNH), where blood cells lack complement regulatory proteins.8 Here, we describe significant adverse reactions to COVID-19 vaccines in 4 patients with PNH.
