National Influenza Vaccination Week 2006


Rebecca Harwell, a former Centers for Disease Control microbiologist in the Respiratory Virus Infections Unit, was shown in this 1968 photograph inoculating a tissue culture in hopes of isolating influenza virions from a throat swab.


After inoculation, the culture was incubated for five to seven days allowing for the possible multiplication of any virions present. If the influenza virus multiplied, it was then identified by using a serological procedure that would determine its serotype.
