Strengthened Response to COVID Vaccines Could Come from the Gut

Sinovac and BioNTech work more effectively in people who have an abundance amount of a particular bacterium called Bifidobacterium adolescentis in their gut. In most of us, this reduces with age, modern diet, stress, and the use of antibiotics, and a joint CUHK-HKU study has found that those who lack it have a lower antibody response to the vaccines. This implies that modulating the gut has potential to power up the impact of COVID vaccines……

Vaccine Effectiveness against Seasonal Flu Predictable by Computer

Innovative algorithms developed by a CUHK team, using bioinformatics analysis of virus genome, can estimate vaccine effectiveness (VE) by quantifying the relationship between the genetic mismatch between flu vaccines and current virus strains. This real-time prediction method of VE early in flu season gives the government a heads-up in selecting effective vaccines and organising resources before mass vaccination ……

Vaccine and Distancing in Tandem Vital Against Virus

Research results show that physical distancing can only be relaxed in ratio to the rate of vaccination in the city’s population until herd immunity is achieved. A CUHK team developed a social contact index (SCI) which quantifies the effect of distancing and vaccination combined, to bridge gaps between intervention measures and disease transmission……
