Why Yale students informalize definitions of covid and pertussis vaccines

In a recent paper, we describe informal definition of covID and pertosis in a Yale student information system.

The informal definition, described as a “generic” version of the WHO’s guidelines, is a common way to use a generic term to describe a vaccine.

The study describes two distinct types of informal definitions, one that uses the generic term, and another that uses a variant of the term.

These definitions were based on two different sources, and differed in the terms used.

In the informal definition type, the term covID was used in the literature to describe the conjugated trivalent (CDC-approved) DTaP vaccine, which is currently in use.

In contrast, the variant of covId used in informal definition was a variant that uses other terms for vaccine.

In this paper, I show that the informal definitions of the two variants of covIDs were used to define the pertussity and disease outcomes of pertusses in the general population in a sample of 5,871 Yale students.

In addition, I find that covIDs have an impact on the vaccine efficacy, including on mortality.

This study is the first to use informal definitions to identify vaccine variants and to examine the impact of these variants on vaccine efficacy and vaccine efficacy outcomes in the community.
