Disastrous COVID Immune Escape Mutants (including E484K) | Global Health Watch with Dr. Sean Lin
The COVID-19 variant from UK (B.1.1.7 lineage) has drawn global attention. However, the variant fro South Africa (501Y.v2) was more disastrous, as it contains immune escape mutations that might make neutralizing antibodies ineffective. This variant has been identified in several countries already. And it will seriously challenge the efficacy of current vaccine products. In this episode, I will talk about recent studies (both in vitro and in vivo) related to escape mutants containing the E484K mutation that is in the Receptor Binding Domain (RBD) of the Spike protein.

Will WHO Team Find Out the Origin of COVID-19 in China? | Global Health Watch | Dr. Sean Lin
World Health Organization (WHO) just sent an expert team to China to investigate the origin of COVID-19 outbreak in China. Will it be an independent investigation? Will they be able to access previous research documents that were not allowed to be published? Who will write the report when the investigation is done? Should they go to the current outbreak hotspots like Hebei Province?

Alarming Immune Escape Mutant (l452R) Strain in California! | Global Health Watch
The California Department of Public Health announced that an L452R variant of COVID-19 is increasingly being identified in multiple counties across the state. The 452R variant has previously been detected in other countries and states, and is now increasingly being found in multiple counties throughout California. Previous studies have shown that the L452R is an immune escape mutant that significantly reduce monoclonal antibody recognition. This might be a very important reason that the COVID-19 cases in CA has a huge increase in the past few weeks.

COVID-19's Effects on the Brain | Global Health Watch
Autopsy studies have not yet shown destructive viral invasion into patients’ brains. But, why SARS-CoV-2 causes neurological symptoms in some patients? What would be the alternative routes? Can SARS-CoV-2 hide in human brains for a purpose? In this episode, I will share some new studies regarding COVID's impact on brain and neurological system.
