Guest guest Posted December 21, 2008 Report Share Posted December 21, 2008 For your information. Do your own research. There have been 9 deaths a year 9approx) from PErtussis. Balance that against other risks to make a decision. The reason we chose not to immunize Elie against Pertussis was due to WHOLE CELL P being given. I will revisit this subject withour doc as to the acellular vaccine. I do believe in vaccination - with caution- . Elie has had everything available EXCEPT the P. Vaccines [edit<http://en.wikipedia.org/w/index.php?title=Pertussis & action=edit & section=6> ] History of pertussis vaccine development Infection with pertussis induces immunity, but not lasting protective immunity, and a second attack is possible.[4]<http://en.wikipedia.org/wiki/Pertussis#cite_note-3>Efforts to develop an inactivated whole-cell pertussis vaccine <http://en.wikipedia.org/wiki/Vaccine> began soon after *B. pertussis* was grown in pure culture in 1906. In the 1920s Dr. Louis Sauer developed a vaccine for whooping cough at ton Hospital (Chicago, IL). In 1925, the Danish physician Thorvald Madsen<http://en.wikipedia.org/w/index.php?title=Thorvald_Madsen & action=edit & red\ link=1>was the first to test a whole-cell pertussis vaccine on a wide scale. [5] <http://en.wikipedia.org/wiki/Pertussis#cite_note-Baker_2004-4> He used the vaccine to control outbreaks in the Faroe Islands in the North Sea. In 1942, the American scientist Pearl Kendrick<http://en.wikipedia.org/w/index.php?title=Pearl_Kendrick & action=edit & re\ dlink=1>combined the whole-cell pertussis vaccine with diphtheria <http://en.wikipedia.org/wiki/Diphtheria> and tetanus<http://en.wikipedia.org/wiki/Tetanus>toxoids to generate the first DTP combination vaccine. To minimize the frequent side effects caused by the pertussis component of the vaccine, the Japanese scientist Yuji Sato<http://en.wikipedia.org/w/index.php?title=Yuji_Sato & action=edit & redlink=1>d\ eveloped an acellular pertussis vaccine consisting of purified haemagglutinins (HAs: filamentous HA and leucocytosis-promoting-factor HA), which are secreted by *B. pertussis* into the culture medium. Sato's acellular pertussis vaccine was used in Japan since the autumn of 1981.[6]<http://en.wikipedia.org/wiki/Pertussis#cite_note-Sato_1984-5>Later versions of the acellular pertussis vaccine used in other countries consisted of additional defined components of *B. pertussis* and were often part of the DTaP <http://en.wikipedia.org/wiki/DTaP> combination vaccine. [edit<http://en.wikipedia.org/w/index.php?title=Pertussis & action=edit & section=7> ] Current status of pertussis vaccines Pertussis vaccines are highly effective, strongly recommended, and save many infant lives every year. Though the protection they offer lasts only a few years, they are given so that immunity lasts through childhood, the time of greatest exposure and greatest risk.[7]<http://en.wikipedia.org/wiki/Pertussis#cite_note-6>The immunizations <http://en.wikipedia.org/wiki/Immunization_(medicine)> are given in combination with tetanus <http://en.wikipedia.org/wiki/Tetanus>, diphtheria <http://en.wikipedia.org/wiki/Diphtheria>, polio and haemophilus influenzae type B immunizations, at ages 2, 3, and 4 months, and a later booster at 3 years and 4 months or soon after ( http://www.immunisation.nhs.uk/). The short term effectiveness of the vaccines and the presence of *B. pertussis* infection in adults and adolescents who may transmit the bacteria to infants have caused many in the medical field to call for booster immunizations at later ages. Although Canada, France, the U.S. and Germany now have approved booster shots for adolescents, adults, or both, other countries adhere to the tradition of discontinuing pertussis vaccination after the age of seven, from concerns that there are side effects associated with the first available " whole-cell " pertussis immunizations that tended to increase with age.[*citation needed<http://en.wikipedia.org/wiki/Wikipedia:Citation_needed> *] The whole-cell vaccine is still used in poor countries, since it is cheaper than the newer and safer acellular formulation. As the immunity from infection or vaccination lasts only a few years, the discontinuation of booster vaccination in older persons caused the emergence of a large pool of older persons lacking immunity, followed by an increase of adult-onset pertussis that accelerated beginning in about 2004.[8]<http://en.wikipedia.org/wiki/Pertussis#cite_note-7>This burgeoning outbreak is predicted to increasingly infect adults and adolescents with debilitating cases, but poses even more serious public health dangers to newborns. As adolescent and adult cases surge, newborns are again at risk of exposure to pertussis circulating in adolescents or adults in the community before the infants' vaccinations can be completed. The decision to resume vaccinating teens and adults reflects in part that the newer acellular vaccine, known as DTaP, has greatly reduced the incidence of adverse effects observed with the earlier " whole-cell " pertussis vaccine. An acellular vaccine preparation for adults and adolescents has been approved in Canada<http://en.wikipedia.org/wiki/Canada>, Europe, and the United States <http://en.wikipedia.org/wiki/United_States>. In the U.S., the Food and Drug Administration<http://en.wikipedia.org/wiki/Food_and_Drug_Administration>has authorized both the use of the vaccines Boostrix ( GlaxoKline <http://en.wikipedia.org/wiki/GlaxoKline>) for 10-18 year olds in May 2005 and Adacel (Sanofi Pasteur<http://en.wikipedia.org/wiki/Sanofi_Pasteur>) for 11-64 year olds in August 2005.[9]<http://en.wikipedia.org/wiki/Pertussis#cite_note-8>These vaccines are recommended for all teens and adults within the indicated age ranges, except for those with a history of adverse reaction to the whole-cell pertussis vaccines. The most serious side-effects of traditional " whole-cell " pertussis immunizations were neurological<http://en.wikipedia.org/wiki/Neurology>: and included seizures <http://en.wikipedia.org/wiki/Seizure> and hypotonic<http://en.wikipedia.org/wiki/Tonicity#Hypotonicity>episodes. [edit<http://en.wikipedia.org/w/index.php?title=Pertussis & action=edit & section=8> ] Whole-cell pertussis vaccine controversy Much of the controversy surrounding the DTP vaccine in the 1970s and 1980s related to the question of whether the whole-cell pertussis component caused permanent brain injury in rare cases. Although it was well-established that the pertussis component of the DTP vaccine accounted for most of the minor local and systemic side effects in many vaccinated infants, several published studies failed to show a causal relationship between administration of the DTP vaccine and permanent brain injury. However, criticism of these studies and well-publicized anecdotal reports of DTP-induced permanent disability and death gave rise to anti-DTP movements.[ 10] <http://en.wikipedia.org/wiki/Pertussis#cite_note-Geier_2002-9> In addition, a number of children suffered allergic reactions to the pertussis vaccination, including severe seizures. Despite this, doctors recommended the vaccine, and even threatened to report parents who refused to vaccinate their children[*citation needed<http://en.wikipedia.org/wiki/Wikipedia:Citation_needed> *]. By the late 1970s, publicity about adverse reactions and deaths following pertussis vaccination caused the immunization rate to fall in several countries, including Great Britain, Sweden, and Japan. In many cases, a dramatic increase in the incidence of pertussis followed.[11]<http://en.wikipedia.org/wiki/Pertussis#cite_note-Gangarosa_1998-10\ >These developments led Yuji Sato to introduce a safer acellular version of the pertussis vaccine for Japan in 1981. Nevertheless, other countries continued to use the whole-cell DTP formulation. In the United States, low profit margins and an increase in vaccine-related lawsuits led many manufacturers to stop producing the DTP vaccine by the early 1980s.[*citation needed<http://en.wikipedia.org/wiki/Wikipedia:Citation_needed> *] In 1982, the television documentary " DTP: Vaccine Roulette " depicted the lives of children whose severe disabilities were blamed on the DTP vaccine. The negative publicity generated by the documentary led to a tremendous increase in the number of lawsuits filed against vaccine manufacturers.[12]<http://en.wikipedia.org/wiki/Pertussis#cite_note-_2006-1\ 1>By 1985, manufacturers of vaccines had difficulty obtaining liability insurance. The price of the DTP vaccine skyrocketed, leading to shortages around the country. Only one manufacturer of the DPT vaccine remained in the U.S. by the end of 1985. To avert a vaccine crisis, Congress in 1986 passed the National Childhood Vaccine Injury Act<http://en.wikipedia.org/wiki/National_Childhood_Vaccine_Injury_Act>(NCVIA), which established a federal no-fault system to compensate victims of injury caused by mandated vaccines.[13]<http://en.wikipedia.org/wiki/Pertussis#cite_note-_1988-12>Sin\ ce then, the prices of vaccines have stabilized, and the number of lawsuits filed against DTP manufacturers has dwindled. The majority of claims that have been filed through the NCVIA have been related to injuries allegedly caused by the whole-cell DTP vaccine. The acellular pertussis vaccine was approved in the United States in 1992 for use in the combination DTaP vaccine. Research has shown the acellular vaccine to be safe, with few reports of adverse effects.[14]<http://en.wikipedia.org/wiki/Pertussis#cite_note-pmid15933223-13>Al\ though the whole-cell DTP vaccine is no longer used in the United States, it is still purchased by the World Health Organization<http://en.wikipedia.org/wiki/World_Health_Organization>and distributed to developing nations because of its much reduced cost compared to the acellular DTaP <http://en.wikipedia.org/wiki/DTaP> vaccine. -- Sara - Life is a journey- we choose the path.
