Presently, there is lack of a vaccine that would lead to immunization against the virus COVID-19, but here are some of the characteristics that various seaweeds have and which may provide a glimpse into potential solutions of this global health problem in the near future and possibly forearm us for any future such pandemics. Many species of marine algae contain significant quantities of complex structural sulphated polysaccharides that have been shown to inhibit the replication of enveloped viruses. Other compounds, both of red algae (e.g., the lectin griffithsin and the phycocolloid carrageenan), and other sulphated polysaccharides extracted from green algae (i.e., ulvans) and brown algae (i.e., fucoidans) could be potential antiviral therapeutic agents against SARS-CoV-2.

目前，还缺乏一种疫苗可以导致针对病毒 COVID-19 的免疫接种，但以下是各种海藻所具有的一些特征，这些特征可以让我们一窥在不久的将来解决这一全球健康问题的潜在解决方案，以及可能为我们未来的任何此类流行病做好准备。许多种类的海藻含有大量结构复杂的硫酸化多糖，这些多糖已被证明可抑制包膜病毒的复制。其他化合物，包括红藻（例如，凝集素 griffithsin 和藻胶体角叉菜胶），以及从绿藻（即，绿藻多糖）和褐藻（即，岩藻多糖）中提取的其他硫酸化多糖，可能是针对 SARS-CoV 的潜在抗病毒治疗剂-2。
