HIV-positive individuals are protected by Covid vaccines

Folks contaminated with HIV who obtain antiretroviral remedy type antibodies in opposition to Sars-Cov-2 after being vaccinated in opposition to Covid with mRNA vaccines. Their immune response to the vaccination is, nevertheless, much less sturdy than that of wholesome individuals. A 3rd vaccination reduces this hole. These outcomes emerged from a research with a complete of 91 members carried out by a analysis staff led by Professor Ingo Schmitz, head of the Division of Molecular Immunology at Ruhr College Bochum, Germany. The researchers revealed their findings within the journal “Frontiers in Immunology” of two December 2022.

Vaccine safety in sufferers with acquired immunodeficiency

Research have proven that the vaccines in opposition to Sars-Cov-2 shield in any other case wholesome individuals fairly nicely in opposition to extreme Covid-19. Thus far, it has remained unclear whether or not that is additionally the case for individuals with acquired immunodeficiency. The analysis staff headed by Ingo Schmitz and Dr. Anja Potthoff from the Stroll in Ruhr (WIR) Zentrum für Sexuelle Gesundheit und Medizin (Centre for Sexual Well being and Drugs) on the college hospital of Ruhr College Bochum carried out a research with 71 HIV-positive members who have been receiving antiretroviral remedy. As well as, 20 HIV-negative management topics took half within the research. After the primary, second and third vaccination with the Biontech/Pfizer mRNA vaccine, they analyzed the immune response of every participant.

“We discovered that the vaccination results in this group forming antibodies, too, however much less nicely than is the case for wholesome individuals,” says Ingo Schmitz. “Seeing as this hole was decreased after a 3rd shot, we imagine that booster vaccinations ought to be really helpful.”

Surprisingly good mobile immune response

The researchers have been shocked to find that the mobile immune response mediated by T-helper cells was simply nearly as good in HIV-positive as in HIV-negative individuals. “That is even supposing it’s exactly these T-helper cells which might be attacked by the HI virus and are decreased in quantity in HIV-positive individuals,” stresses Ingo Schmitz. Since T-helper cells are longer lived than antibodies, this would possibly point out that HIV-positive individuals are protected by the vaccine roughly so long as HIV-negative individuals.

Cooperation companions

Along with the Division of Molecular Immunology at Ruhr College Bochum, the research additionally concerned the Division of Molecular and Medical Virology, the Leibniz Analysis Centre for Working Atmosphere and Human Elements at TU Dortmund College IfADo, WIR – Stroll In Ruhr, Zentrum für sexuelle Gesundheit und Medizin (Centre for Sexual Well being and Drugs) in addition to the college hospitals for haematology, oncology and palliative drugs, the clinic for dermatology and the clinic for neurology at St. Josef Hospital Bochum.


The venture was funded by the state of North Rhine-Westphalia as a part of the analysis grant “SARS-CoV-2 particular T-cell diagnostics”, venture no. MIL-1-1.
