HIV status does not affect immune responses to Oxford/AstraZeneca vaccine, two studies show

Two studies of immune responses to the Oxford/AstraZeneca COVID-19 vaccine show that the vaccine produced similar immune responses in people with or without HIV. People with HIV did not experience more side effects from the vaccine. The findings have been made available as pre-prints, which means that they have not been peer-reviewed yet. There is… Read More »

Differing immune responses discovered in asymptomatic cases vs those with severe COVID-19

The largest study of its type in the UK has identified differences in the immune response to COVID-19, between people with no symptoms, compared to those suffering a more serious reaction to the virus. Researchers from the Wellcome Sanger Institute, Newcastle University, University College London, University of Cambridge, EMBL’s European Bioinformatics Institute (EMBL-EBI) and their… Read More »

People with NNRTI resistance have poorer responses to dolutegravir, South African study finds

People with HIV who already have resistance to a non-nucleoside reverse transcriptase inhibitor (NNRTI) when they start first-line antiretroviral treatment containing the integrase inhibitor dolutegravir were less likely to achieve viral suppression, a large clinical trial in South Africa has reported. NNRTI resistance has not been shown to affect responses to dolutegravir-based treatment previously. The… Read More »

What and how much we eat might change our internal clocks and hormone responses

For the first time, a study shows how glucocorticoid hormones, such as cortisol, control sugar and fat levels differently during day and night, feeding and fasting, rest and activity, over the course of 24 hours. The research conducted in mice found that the time-of-day dependent metabolic cycle is altered by high caloric diet. Since glucocorticoids… Read More »
