Because of the high rate of side effects, scientists developed a more purified version of the pertussis vaccine, referred to as the acellular pertussis vaccine.
A newer version of the vaccine, called the acellular pertussis vaccine, contains fewer pertussis proteins and causes fewer reactions.
He was an early champion for the introduction of safer whooping cough vaccines, called acellular vaccines.
Therefore, the anthrax vaccine is made in a manner similar to the "acellular" pertussis vaccine.
In 1996 a new ( "acellular") pertussis vaccine was available for use in the United States.
The new "acellular" pertussis vaccine had a much lower risk of severe side effects than the old "whole-cell" vaccine.
The new "acellular" pertussis vaccine, the one that has been in use in the United States since 1996, has a rate of both mild and severe side effects that is at least 10-fold less than that found for the "old" pertussis vaccine (see Are vaccines safe?).
The new "acellular" pertussis vaccine has a much lower risk of severe side effects than the old "whole cell" vaccine.
This vaccine is called the "acellular" pertussis vaccine (or aP) and is purer than the old "whole cell" pertussis vaccine.
A new "acellular" pertussis vaccine was recently approved for all adolescents 11 and 12 years of age and adults.
