Tuberculosis and BCG vaccination.
My advice as a
pathologist is that the TB vaccination (BCG) should be given at birth.
Furthermore, Mantoux test should
be done before adolescent are vaccinated.
There were only two
in our class (I was one and the other was Donald, Jaffna Tamil, my
best friend) who were Mantoux negative out of over 50).
Only two of us got the BCG vaccination.
In other word 95%
were exposed to TB as a Child (they should not be vaccinated to avoid
reactivation of OLD TB).
This is true in India and Africa.
Then there is also
Atypical or Anonymous Tuberculosis (PHD thesis of one of my teachers
was not validated by the crooked supervising committee.in Peradeniya,
fearing one may not get a chance to go abroad for higher studies).
Local degrees were considered inferior.
So annoyed my
teacher gave up local research and ended up in Australia as a GP.
He had five children
and all of them are doing well in many fields abroad.
So I decided to do
my research in this country well past 50 yeas (my thesis) and part of
the good quality data, I never gave to the University but used as my base
for three books published at Amazon.)
By the way, I used five times the university contribution from my own pocket.
The money allocated was meager.
Coming to TB
vaccination (polybacterial and polyvalent) as a whole there are lot
of antigenic particles that activate lymphocytes and later taken up
by the macrophages for intracellular digestion.
What it signals is
that the macrophage has a nonspcific receptor on its surface to bind
coated Coronavirus (not RNA particles).
One should identify this receptor in any new protocol.
