Acellular Whooping Cough Vaccine: Is it safe and effective?
In 1975, after a spate of 37 crib deaths linked to vaccination, Japanese doctors in one
prefecture boycotted vaccination. The Japanese Government responded by lifting the
vaccination age to 2 years. However, because there was continued concern about the safety
of the whole-cell vaccine, they also developed a new, acellular vaccine which was hoped to
be less reactogenic than the standard, whole-cell vaccine.
In 1981 Japan introduced a series of acellular vaccines (Kimura et al. 1991. AJDC; 145:
734) which were supposed to be less reactogenic. However, trials with 115 children ranging
in age from about 3 to 23 months showed that local adverse reactions started about 7 days
after the first, and 48 hours after the second, third and booster DPT injections
containing the acellular pertussis vaccines. Practically every child had some form of
local reaction. Noble et al. (Jama 1987; 257 (10): 1351) concluded that the incidence of
more serious local reactions and high temperature may be more common after vaccination
with acellular vaccines. They hoped that some questions regarding product-specific and
age-specific efficacy may be answered by the then ongoing field trials of Japanese
acellular vaccines begun in 1986 in Sweden.
In Japan, the acellular vaccines were quickly introduced into widespread use before
characterization of pertussis antigen contained in the vaccine was completely known. At
the time of their introduction, the only requirement of efficacy for Japanese acellular
vaccines was their potency, determined by the intracerebral mouse protection test.
The 1986/1987 Swedish trial of two Japanese acellular vaccines ended in a fiasco: the
efficacy of one vaccine was only 69% and of the other only 54%; Swedish health authorities
withdrew their license application (Lancet 1989: 814).
In the meantime, other countries, including the United States continued the use of the
whole-cell whooping cough vaccine. However, Pichichero et al. (1992. Pediatrics; 89(5):
882) published an evaluation of immunogenicty of and adverse reactions to a two-component
acellular pertussis vaccine when given as a primary immunization series at 2, 4 and 6
months of age. They concluded that this acellular vaccine produced greater immunogenicity
and fewer adverse effects than the currently licensed whole-cell vaccine. However, one
only had to look at the number of withdrawals and the reasons for withdrawals of babies
from the trial, to see that this statement was overly optimistic. 31 of the 380 children
withdrew from the study and there was a high incidence of drowsiness and irritability in
the recipients of both whole-cell and acellular vaccines and a higher than expected rate
of unusual high-pitched crying. High-pitched or cerebral cry
indicates great pain due to brain inflammation. The total oblivion of these researchers to
the encephalitogenic effects of the acellular vaccines administered to such young babies
is quite incredible.
On the basis of this trial, the acellular vaccine was licensed in the US as a booster in
older babies, after the 3 primary shots. The way pro-vaccinators advertising the acellular
whooping cough vaccines write about them is quite astonishing and certainly revealing:
The National Institute of Child Health and Human Development said...that the new
vaccine was about 71% effective in preventing whooping cough among 1,700 infants who were
inoculated. A whooping cough, or pertussis vaccine, used in the United States since the
1940s contains a dead pertussis cell...But the vaccine also contains a toxin that in some
infants can cause serious side effects...Some doctors claimed that the vaccine can cause
brain damage and even death....More that $487 million has been paid in compensation awards
through the vaccine injury program (Washington Press 1994).
In Australia the new acellular vaccine was tested on 5 and 6 year old children in Geelong
(Victoria). Parents were told that it is a new formula, but side effects would only be
mild. In reality half the recipients were absent from school for several days, and many
were admitted in hospitals. Parents were outraged that their children were used as guinea
pigs, so the Victora Chief Health Officer published that it was not a new vaccine,...it
was in fact the same vaccine that has been given for a decade to younger children from the
age of two months...reaction to the vaccine reported by parents was expected and the
National Health and Medical Research Councils 1994 Immunization Handbook sent to all
doctors (Note: not to parents, and, the doctors who got the handbook did not warn parents)
throughout Australia listed possible side effects. These side effects which are listed on
the consent form sent home with children by schools prior to vaccination, include
localized pain, redness and swelling at the injection site and mild fever (38 degrees
Celsius). Other possible side effects are that the child may become grizzly, unsettled and
generally unhappy for 24 hours, plus also becoming drowsy. Commenting on high number
of children becoming sick, the officer said: This figure, we believe could reflect a
parents inexperience with this vaccine in this age child, who tends to make his
feelings known more forcible than babies.
The reader should ask themselves what sort of reasoning is this. Just because tiny babies
can not talk, their vaccine reactions are more acceptable than in the children who can
talk and tell their parents how lousy they feel after being injected with?
Science News (1995; 48: 54) published an article New pertussis vaccines safer, more
effective. Anthony S. Fauci, director of the National Institute of Allergy and
Infectious Diseases, which cosponsored the new vaccine trials, hailed the acellular
vaccine as truly effective. Current vaccines used in the United States
contain whole, but inactive, bacteria that cause fever, swelling, fussiness and - very
rarely - neurological damage...some countries including Sweden and Italy dont
require a pertussis vaccination. And In the Swedish study, infants received a
five-component or a two-component acellular vaccine, the standard whole-cell vaccine, or
no vaccine. The five-component acellular vaccine gave 85% protection, while the
two-component vaccine gave 58% protection. The Italian study tested two kinds of
three-component acellular vaccines against the standard vaccine or no vaccine. Both
acellular vaccines offered 84% protection. Surprisingly, the whole-cell vaccine offered no
better than 48% protection. Fauci speculates that it performed poorly because the trials
omitted boosters. Fauci advised parents to continue with the standard immunization
schedule.
Get the picture? No country which considers itself to be democratic should ever force any
medical procedure on its citizens. This is especially valid of vaccines, which are neither
safe nor effective, but most of all, quite unnecessary. Infectious diseases of childhood
are beneficial for children. They prime and mature the immune system of children and
represent developmental milestones. Who with of a sound mind would try, no matter how
unsuccessfully, to prevent children from developing normal immunological responses and
reach developmental milestones?
