A #HKUSPH & The University of Chicago research on childhood immune imprinting studied data in Hong Kong and finds: ▪those imprinted to H1N1/H2N2 ➡17% lower risk of getting H1N1 ▪if imprinted to H3N2 ➡12% lower risk Tim Tsang Sarah Cobey Ben Cowling Journal of Infectious Diseases:bit.ly/3Xvml9M

A subset of individuals with SARS-CoV-2 are three times more likely to spread the virus to other individuals than the average person. elifesciences.org/articles/82611…

A #HKUSPH research observes high mortality during the Omicron BA.2 wave in Hong Kong due to lower vaccine coverage (42%) among adults ≥65 years old. ⬆ in antiviral usage & vaccination uptake over time in 2022 was associated with ⬇ case fatality risks. medrxiv.org/content/10.110…

our Cobovax study observed similar incidences of omicron BA.2 infection across diff vaccination groups despite weak neutralising antibodies to BA.2 in 3rd-dose CoronaVac recipients, suggesting nAbs may not be appropriate correlates of protection for inactivated COVID-19 vaccines

How should we interpret recent patterns of SARS-CoV-2 evolution, from EG.5 to the new BA.2 descendent? What can we learn from other viruses? And where might things being heading next? I discuss some of the key ideas and research: kucharski.substack.com/p/what-next-fo…

Fantastic opening to our 3-day international conference this morning #immunity2023 with many excellent presentations including opening talks by Malik Peiris and Maria Van Kerkove

Reconstructing household transmission dynamics to estimate the infectiousness of asymptomatic influenza virus infections | PNAS pnas.org/doi/abs/10.107…

Our recent study reassessed the lift of universal masks mandate suggested no evidence that such lift reduced SARS-CoV-2 transmission in schools. However, we revealed a significant difference when using incidence or transmissibility as outcome measurement. academic.oup.com/pnasnexus/arti…

Watching Aubree Gordon give a fantastic talk on the dynamics of flu infections in her extensive pediatric cohorts. Answering important questions about the length of infection-associated protection (infection protects better and longer than vaccination—hope for better vaccines!

【Latest Research】A team led by Bingyi Yang, Research Assistant Professor of #HKUSPH has revealed that neutralizing antibodies (nAbs) serve as a key immune correlate for COVID-19 vaccine protection. 🔍 Key Findings: ✔️ Neutralizing antibody (nAbs) levels and vaccine efficacy /

【Latest Research】A recent study led by Dr Bingyi Yang, Research Assistant Professor of #HKUSPH has analysed 200,000 hemagglutination inhibition (HAI) titrations from ferret models. This research reveals critical insights about influenza immune evasion. 🦠💡 🔍 Key Findings: ✔️
