Immunogenicity and reactogenicity of the adult tetanus–diphtheria vaccine. How many doses are necessary?

Immunogenicity and reactogenicity of indigenously produced MMR vaccine.

OBJECTIVES To study immunogenicity and reactogenicity of indigenously produced MMR vaccine and to assess the booster effect of MMR immunization on measles seroconversion. DESIGN A longitudinal follow up. SETTING Hospital based and home follow up, as required. SUBJECTS 89 children already immunized for measles, between 15 to 24 months of age for immunogenic evaluation and 866 subjects for ...

How Many Bootstrap Replicates Are Necessary?

Phylogenetic bootstrapping (BS) is a standard technique for inferring confidence values on phylogenetic trees that is based on reconstructing many trees from minor variations of the input data, trees called replicates. BS is used with all phylogenetic reconstruction approaches, but we focus here on one of the most popular, maximum likelihood (ML). Because ML inference is so computationally dema...

Classification of emergency department visits: how many are necessary?

In a recent year, hospital emergency departments (EDs) in Rhode Island provided care to over 380,000 patients who did not require subsequent admission to an inpatient or observation bed.1 Many ED visits are for true emergencies that could not be treated in other health care settings, but there has been much discussion among providers, payers, and policy makers on whether some of these patients ...

Immunogenicity and reactogenicity of 1 versus 2 doses of trivalent inactivated influenza vaccine in vaccine-naive 5-8-year-old children.

BACKGROUND Two doses of trivalent inactivated influenza vaccine (TIV) are recommended for children <9 years old receiving vaccine for the first time, but compliance is suboptimal. This study assessed the need for a second dose of TIV in this age group. METHODS In this prospective, open-label study, 232 influenza vaccine-naive 5-8-year-olds enrolled in a health maintenance organization receive...
