Insights
Investigating COVID-19 vaccine effectiveness and immune responses in people living with HIV-1 (PLWH) in Africa is crucial. This research highlights gaps in understanding SARS-CoV-2 impacts on immunocompromised populations.
Area of Science:
- Immunology
- Virology
- Public Health
Background:
- Immunocompromised individuals, particularly people living with HIV-1 (PLWH), face significant risks from COVID-19, especially in Africa.
- Understanding SARS-CoV-2 infection and vaccination responses in PLWH compared to people without HIV-1 (PWOH) is critical.
Purpose of the Study:
- To examine COVID-19 vaccine effectiveness in PLWH.
- To understand antibody responses to SARS-CoV-2 infection and vaccination in PLWH versus PWOH.
- To assess the impact of prior immunity to endemic coronaviruses on SARS-CoV-2 responses in PLWH.
Main Methods:
- Comparative analysis of immune responses (antibody levels, vaccine effectiveness).
- Assessment of pre-existing immunity against endemic human coronaviruses.
- Review of persistent SARS-CoV-2 infection consequences in immunocompromised individuals.
Main Results:
- Key areas requiring further investigation identified regarding COVID-19 in PLWH.
- Potential impact of endemic coronavirus immunity on SARS-CoV-2 responses explored.
- Consequences of persistent infection, including shedding and viral diversity, discussed.
Conclusions:
- Further research is essential to address COVID-19 challenges in immunocompromised populations, especially PLWH in Africa.
- Understanding SARS-CoV-2 evolution and persistent infection dynamics in Africa is crucial for public health strategies.
Abstract:
The effect of COVID-19 on the high number of immunocompromised people living with HIV-1 (PLWH), particularly in Africa, remains a critical concern. Here, we identify key areas that still require further investigation, by examining COVID-19 vaccine effectiveness, and understanding antibody responses in SARS-CoV-2 infection and vaccination in comparison with people without HIV-1 (PWOH). We also assess the potential impact of pre-existing immunity against endemic human coronaviruses on SARS-CoV-2 responses in these individuals. Lastly, we discuss the consequences of persistent infection in PLWH (or other immunocompromised individuals), including prolonged shedding, increased viral diversity within the host, and the implications on SARS-CoV-2 evolution in Africa.

NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
