Dear Reader,
Tick-borne encephalitis (TBE) has always sat at the intersection of ecology, geopolitics, and biotechnology, and this week’s edition makes that tension explicit. We move from China, where surprisingly the Siberian TBEV subtype may predominate, to contemporary eastern Siberia—where four TBEV subtypes co-circulate across a remarkably intricate mosaic of steppes, taiga, and bird migration routes. In Irkutsk’s Ekhirit-Bulagatsky district, TBEV diversity is not an abstract phylogenetic curiosity; our TBE feature article suggests that this is the direct product of landscape, fauna, and land use, with ticks, rodents, livestock, and people co-producing a heterogeneous viral population. We then summarize an article from the TBE BOOK on the discovery of the TBEV the 1930s Soviet Far East, where the virus was first isolated under starkly different and often brutal conditions.Set against this, the history of early Soviet TBE research reminds us that the path from discovery of TBEV to the first vaccine ran through a state that fused real scientific ambition with forced labor, censorship, and carefully staged “heroic discovery” narratives. Read together, these pieces ask what we should learn from history about the political (mis)use of science and medicine today.
From TBE, this ViVa issue leads directly to anti vaccine legislation—a reminder that immunization policy is now as much about narrative governance as about antigen choice. As we track a dense week of World Immunization Week campaigns, NITAG outputs, and manufacturer milestones, we also spotlight exciting literature articles ranging from RSV monoclonals to influenza combination vaccines.
Enjoy the reading!
With all my best wishes – stay healthy and get the vaccine doses you need!
Warm regards,
Editor-in-Chief, Global Health Press

The TBE Newsletter – April EditionThis month in the TBE newsletter, we highlight that Eastern Siberia hosts four subtypes of the tick-borne encephalitis (TBE) virus—Siberian, Far Eastern, European, and Baikal. These subtypes circulate together in the same region, with the Baikal subtype likely formed from a mix of others. This co-circulation reflects a complex virus ecosystem that may influence disease patterns and vaccine effectiveness.Last month's Snapshot:
