How Much Money Did Jonas
Salk Potentially Forfeit By Not Patenting The Polio Vaccine?
Salk was not called the
“Father of Biophilosophy” without reason. I have explained the possible reasons
why he did not patent the vaccine here: Why didn’t Jonas Salk patent
the polio vaccine?
For those who want a short answer, Salk would
have been richer by $7 billion if his vaccine were patented. Continue reading
for how the number was arrived at.
First a little bit of history and vaccine
mechanism:
·
Producing vaccine on a
large scale requires virus samples in huge quantities and the tech did not
exist when Salk started working on his vaccine.
·
Folks from Harvard –
Enders and Weller – should be given credit for coming up with an effective way
to grow the virus on tissue scraps without getting contaminated by bacteria
(they won the 1954 Nobel prize for their efforts), and this technique was used
in the production of the Salk vaccine.
·
Albert Sabin came up
with a vaccine shortly after Salk, which he claimed was more effective
(debatable). However the important thing is he did not patent his vaccine
either, and both their discoveries were donated for the benefit of mankind.
·
Salk developed a
intravenous “killed virus” vaccine, Sabin developed an oral “live weakened” one.
The principle is – live vaccine builds immunity for a longer time span, where
as killed vaccine needs a “booster” dose to develop life long immunity.
·
The Sabin vaccine works
by counteracting transmission through the intestinal cavity (where the infection
begins), making it a better choice for eradication.
·
Salk vaccine receivers
can still transmit the virus, whereas the Sabin ones do not.
To tackle the question of how much money he
forfeited by not patenting his vaccine, the following facts are to be considered:
·
The oral polio vaccine
is the type widely used all over the world today, as it is cheaper. People
might quote a lot of other reasons, but money is the primary reason (It costs
$2.2 extra per child to administer the intravenous vaccine). The secondary
reason is children in under developed countries (where the vaccine is
administered for free under humanitarian missions) may not visit the doctor a
second time, and vaccination has to be done in a single visit. Efficiency gains
importance over many other criteria in these cases.
·
Center for Disease
Control, Atlanta recommended that Salk virus be used in 1990, and kids in United
States are immunized using the safer “killed” intravenous vaccine instead of
the “live” vaccine, as chances of a healthy child getting infected exist.
·
The cost of the vaccine
would have gone up by 25% if the patent licensing costs are included.
·
Distribution of the
money spent on medicines by income groups: 90% of all medicines produced in the
world are consumed by the upper 15% of the income group. Better said using
charts Poor:1%, Middle 8%, Rich: 90% :
