Each year I inform the students in my Columbia University virology course that all known DNA polymerases – viral or cellular – require a primer to initiate DNA synthesis (it€™s even stated in our textbook, Principles of Virology). This statement is no longer true, as shown by the discovery of two different DNA polymerases that …
A method for making vaccines that induce antibodies against a specific epitope could be used to produce a universal influenza vaccine that would not have to be changed every year.
Infection with yellow fever virus caused the death of a patient 25 years after receiving a kidney transplant, illustrating the difficulties associated with some medical vaccine exemptions.

Michael Rossmann, a leader in the use of X-ray crystallography and cry-electron microscopy to solve the structure of viruses, died on 14 May 2019 at the age of 88.
by Gertrud U. Rey Dengue fever, caused by dengue virus (DENV), is of substantial public health significance in the tropics, where the virus is spread by Aedes mosquitoes. Last week the FDA announced its approval of a first vaccine for the prevention of dengue disease in endemic areas.
Hepatitis D virus is a unique human pathogen. With a circular, negative stranded RNA genome of ~1700 nucleotides, it is the smallest known human virus. Formation of the HDV particle depends on co-infection of cells with a helper virus, hepatitis B virus. Once thought to be specific for humans, related viruses have now been identified …
