A girl stands firm upon a majestic dragon boat, the embodiment of ancient Chinese culture and resilience, with an outsized syringe, a symbol of novel vaccines technologies. The girl battles a tempest of COVID-19 virus that has loomed over the world, using biotechnology. Scientists relentlessly navigate the stormy seas of infectious diseases, which signifies not only the ongoing efforts to combat the current pandemic but also the broader commitment to safeguarding public health through science and innovation. Yu and his colleagues presented a randomized clinical trial of omicron XBB.1.5-containing bivalent COVID-19 mRNA vaccine in head-to-head comparison with other two mRNA vaccines encoding earlier variants, clarifying that newer variant-matched vaccine elicits an enhanced immune response against newly emerged variants. As we navigate through intricate molecular landscapes, vaccines herald a new frontier in our enduring battle against existing and newly emerged pathogens, promising a future where health prevails.

2. Phenazines: Natural products for microbialgrowth control

通讯作者: Manuel Simões

Highlights

•Phenazines are essential for iron acquisition, signalling and biofilm formation.

•Phenazines are recognized as an important source for antimicrobial drug development.

•Phenazine-inspired antibiotics are very active against resistant bacteria.

•Phenazine-based antibiotics are effective against methicillin-resistant Staphylococcus aureu (MRSA), methicillin-resistant Staphylococcus epidermidis (MRSE), and ancomycin-resistant Enterococcus faecium (VRE).

3.Safety, immunogenicity, and preliminary efficacy of a randomized clinical trial of omicron XBB.1.5-containing bivalent mRNA vaccine

通讯作者：周太成，游顶云，韦嘉，张子杰 

Highlights

•XBB.1.5-containing bivalent generated superior immunogenicity against XBB lineages compared to BA.2/BA.5-containing bivalent.

•The efficacy of booster dose against XBB lineages waned after 2-3 months.

•Newer variant-matched vaccine elicits an enhanced immune response against newly emerged variants.

4. A human monoclonal antibody neutralizes SARS-CoV-2 Omicron variants by targeting the upstream region of spike protein HR2 motif

通讯作者：王岚峰, 林正红，张素平

Highlights

•A newly isolated human neutralizing monoclonal antibody 39 (mAb-39) can neutralize SARS-CoV-2 and its variants.

•mAb-39 improves the activity of anti-receptor-binding domain (anti-RBD) antibody against Omicron variants.

•mAb-39 binds to a conserved epitope within the upstream region of the heptad repeat 2 (HR2) motif of Omicron spike protein.

•Point mutation within the upstream region of HR2 reduces the capacity of spike protein-induced membrane fusion.
