Fw: [catholicACT] Re: HIV can go thru the condom?
Further on the biased BBC's Panorama programming. Note the disclaimer on Durex's (condom manufacturer) web site. And NIH's cautious conclusion of its scientific findings.
http://www.spuc.org.uk/papers/biasbbc.pdf
[page 23-24]
Not only are there no scientific studies stating
that condoms are 100% safe but the condom companies and promoters themselves
acknowledge that condoms, even when used consistently, are not foolproof. The cost in
human and legal terms is too serious for them to risk stating otherwise.
The programme failedto mention Durex’s statement on their website: "Latex condoms, when used consistently and
correctly are a highly effective barrier to the sexual transmission of HIV and other STIs."
Unfortunately, as well-informed people are aware (but not, it would appear, the makers of
Sex14
http://www.usaid.gov/pop_health/aids/Countries/africa/uganda_report.pdf24
and the Holy City)
‘correct and consistent use’ is the ideal more often than the reality. Thesuccess rate for ‘typical’ use is much lower. More interestingly in this context, Durex goes on
to point out that there is only one 100% effective way of preventing HIV infection.
"However, for complete protection from HIV and other STIs, the only totally effective
measure is sexual abstinence or limiting sexual intercourse to mutually faithful, uninfected
partners." Coincidentally, the Catholic Church endorses this radical, practical and foolproof
method of HIV prevention, as does the World Health Organisation.
What was even more misleading, however, was the
Panorama programme’s misuse of the USNational Institute of Health’s report. We were told:
Bradshaw: The most authoritative recent report is by the US National Institute of Health which
concluded: ‘Intact condoms are essentially impermeable to the smallest sexually transmitted virus’ and
‘that the consistent use of male condoms protects against HIV/AIDS transmissions.’
This quote does not come entirely from the conclusion of the report and is not a single,
condensed reference at all as was suggested. It is spliced from two different sections of the
report, p. 7 and p. 27. Furthermore,
Panorama omitted to mention other key aspects of thisreport:
i) The introduction to the report (p. ii) concluded that ‘because of limitations in study
designs there was insufficient evidence from the epidemiological studies on these
diseases to draw definite conclusions about the effectiveness of the latex male condom
in reducing the transmission of these diseases.’ Why should an investigation by an
allegedly impartial broadcasting corporation fail to mention that the authoritative
report it cites acknowledges itself that it is not authoritative in so far as its evidence is
insufficient and (as point ii illustrates) prone to error?
ii) It recorded the fallibility of any study on condom use because ‘all studies must rely on
self-reported use, a potential source of error due to recall bias’ (p. 5)
iii) It recorded that ‘the combined method failure (slippage plus breakage) is estimated at
1.6% - 3.6% (p. 9) and
iv) ‘approximately 3% of couples who reported using condoms consistently and correctly
(considered "perfect use") are estimated to experience an unintended pregnancy during
the first year of use’ and ‘in a recent well-controlled randomized clinical trial of
monogamous couples using latex male condoms for contraception over six months,
the pregnancy rate during "typical use" was reported at 6.3% (p. 10).
v) Finally, ‘from the two incidence estimates, consistent condom use decreased the risk
of HIV/AIDS transmission by approximately 85%. These data provide strong
evidence for the effectiveness of condoms for reducing sexually transmitted HIV.’
Note ‘reducing’ not ‘preventing’. The programme’s major source of scientific
information for its premise that condoms prevent AIDS transmission admits itself that
condoms decrease risk by only 85% and goes on in its conclusion to state: "it is
important that robust research be pursued to ascertain the true benefits and limitations
of an available risk reduction technology". As John Smeaton commented in an
interview about the
Panorama programme: "Condom use may reduce the risk oftransmission but to spread the message that condom use prevents AIDS is a dangerous
lie. It is no good saying that the risk is 'only 15%', or 'only 1 in 10' when we are
talking about human lives."
15The fact that latex is porous is not a matter for debate. Whether or not the porous nature of
latex can result in viral leakage is a matter of serious contention. What is of interest here,
