Vincent, Alan, and Rich revisit circovirus contamination of Rotarix, then discuss poxvirus-like replication of mimivirus in the cell cytoplasm, and whether seasonal influenza immunization increases the risk of infection with the 2009 H1N1 pandemic virus.

Vincent, Alan, and Matt review contamination of Rotarix with circovirus DNA, antigenic similarity between 1918 and 2009 H1N1 influenza, a collection of rabies reports, and chicken pox mistaken for smallpox in Uganda.

Vincent, Dick, and Alan review a new macaque model for HIV-1 infection, a possible role for Epstein-Barr virus in multiple sclerosis, accidental release of H5N1 by a vaccine company, resistance of frogs to virus infection, and extreme virology – the biggest and smallest viruses and viral genomes.
