Covid-19 vaccination - this is an issue that has attracted much interest, but the government(the Ministry of Health really need to increase efforts on public education. Individual persons must made informed choices not simply as to be vaccinated, but also WHICH vaccine? This is my own opinion.
From my reading, the many different vaccines and many different concerns - I believe a reading of this article by Dr Kumar may expand our knowledge and influence of decision making...
Will I be getting the vaccine as the Ministers and 'more important' people getting...or am I OK with some other kind of vaccine? Am I part of testing a new vaccine - or am I getting a vaccine already tested and known to be safe..
Many issues...many questions ---OR do we simply just 'Oh...shut up, just do as the government tells you...Full stop.. After all, the government knows best...'
Read on - ultimately the CHOICE is yours...I am just sharing Dr Kumar's article, and I am not sure about the accuracy or 'credibility' of the information...so just read, and decide for yourself....who will most likely be considering various other inputs on the same subject matter..
For me personally, I do know Dr Kumar...and I trust him and will consider his views seriously...
Other concerns - Are we affected by personal biases, sometimes generated by certain Media? Are there politicians 'pocketing monies' from pharmaceutical companies, to influence their countries to get vaccines from this and that company? Is 'money-making' or other irrelevant considerations influencing government decisions making in this public health issue?
*Coronavirus Vaccines*
_By Dr Jeyakumar Devaraj_
It is quite clear that we need to use the Covid vaccine to overcome the coronavirus pandemic.
If
a significant portion of our population were to be immune – even if
partially or for a period of one or two years – then the rate of
transmission of the coronavirus would drop.
That
would mean we can reduce the level of physical distancing, and more
people can return to their jobs and businesses, and our economy can
begin recover.
Close to
60 Covid vaccines are being developed, and a few are already being
administered on a mass basis. But it is important to do it right and to
make sure that the ‘cure’ doesn’t cause new health problems.
Vaccines
work by presenting a viral protein or proteins to the subject to coach
the subject’s immune system to develop antibodies that can neutralise
the real virus if and when the real virus attacks the subject.
*We can divide the Covid vaccines into two main groups:*
Vaccines that use inactivated Covid viruses or laboratory-manufactured Covid protein to stimulate this immune response.
Vaccines
that use a new technology that makes the subject’s own body produce the
Covid protein that then stimulates the subject’s immune system to
produce the neutralising antibodies
*‘Old-tech’ Vaccines*
The
first group of Covid vaccines relies on old and tested vaccine
technology that we have been using for the past 50 years to produce
vaccines for various diseases.
The medical community is familiar with the potential downsides of this first group.
These include insufficient inactivation of the virus, which means the virus is still able to replicate in the subject’s body.
Side
effects may occur due to the chemicals used to inactivate the virus or
due to the various adjuvants used to enhance the body’s reaction to the
viral protein. (Aluminum is one of the adjuvants used to “irritate” the
immune system.)
*More sophisticated vaccines*
The
second group of Covid vaccines comprise RNA or DNA which instruct our
cells to make the Covid-spike protein when this genetic material is
injected. This approach is new and has not been used in the production
of any vaccines for a mass vaccination campaign.
This
‘canggih’ (sophisticated) approach involves injecting the genetic code
for the Covid spike protein into the subject’s body. This genetic code
enters the subject’s cells and tricks the subject’s ribosomes to produce
thousands of copies of the Covid spike protein.
Ribosomes
are the organelles within our cells that produce proteins, as
instructed by the nucleus of the cell. The nucleus sends out messenger
RNA to the ribosomes to tell it what type of protein to produce.
These modernistic Covid vaccines rely on messenger RNA that code for the Covid protein.
In
the Pfizer and Moderna vaccines, the messenger RNA (mRNA) that codes
for the Covid spike protein is put in minute phospholipid capsules, and
many of these capsules are injected into the subject.
These
capsules circulate in the blood and slip into certain cells in the body
where the mRNA instructs the ribosomes of these cells to manufacture
the Covid spike protein.
Some
of these spike protein molecules extrude from the cells into the
bloodstream and catch the attention of the immune system, which then
produces antibodies against these spike proteins. The spike proteins
sticking out of the “infected” cells also induce killer lymphocytes to
attack and kill these cells.
It
is possible that these modern vaccines are more effective than the
traditional ones in that they induce more cell mediated-response (the
killer lymphocytes).
But
that is part of the problem with them. These modern vaccines involve the
destruction of some of the subject’s cells. Do the developers of these
vaccines know for sure that their phospholipid capsules will not slip
into nerve cells or into kidney cells? These are tissues that are not
particularly capable of regenerating themselves if they are damaged.
We
also do not know the longer-term consequences of exciting the body’s
immune system and then exposing that system to cellular antigens
released by the destruction of the RNA ‘infected’ cells. Might this
induce an auto-immune disease in a portion of the people so exposed?
Auto-immune
diseases are conditions in which the body’s immune system starts
attacking some component of the body. Rheumatoid arthritis is one
example of an auto-immune disease and we still do not understand why it
affects certain people or what sets it off.
Would
Covid vaccines that rely on generating viral proteins within our own
cells precipitate auto-immune disease in those so predisposed? We do not
know. It may not happen, but shouldn’t we make sure that it doesn’t
before we inject this vaccine into millions of people?
The
Oxford-AstraZeneca and Sputnik V vaccines use a different strategy to
deliver the Covid genetic code for the spike protein to the subject
cells.
They convert the
Covid code to DNA, which is more stable and does not require ultra-cold
storage. They then put this DNA into modified Adeno viruses, which are
incapable of replicating in the subject’s body. These modified Adeno
viruses deliver the DNA code to the subject’s cells.
As
Adeno viruses cause respiratory tract infections, these vaccines will
infect respiratory tissues and are less likely to affect nerve and
kidney cells.
But as
these vaccines use DNA to code for the spike protein, the
vaccine-delivered DNA has to go into the nucleus of the subject’s cell
to produce the messenger RNA that can instruct the subject’s ribosomes
to produce the spike protein.
Willfully
putting foreign DNA into the nucleus of human cells is something we
should not take lightly. We know that in certain viral infections, viral
DNA becomes incorporated into the human chromosomes. This occurs in
hepatitis B and in HIV infections.
Do
we know for sure that this will not occur, in perhaps a small
percentage of cases, with the Covid vaccines that use DNA? Will this
viral gene interact with any other gene in our genome and cause a health
problem? Maybe not, but should we take that risk?
Look
at the alternatives. Let us be clear here. I am not an anti-vaxxer.
Vaccines have played a huge role in the control of infectious diseases
in the past 50 years, and they certainly have a big role to play in the
future.
The crucial
question is, do we need desperate measures such as deploying the new RNA
and DNA vaccines on a global scale before checking carefully that they
do not cause unexpected negative effects in the medium to long term?
After
all, there are other effective alternatives. Several Covid vaccines
have been produced using traditional vaccine technology. These
‘old-tech’ vaccines do not rely on RNA or DNA and do not involve the
subject’s cells in the generation of the viral antigen.
The
old-tech vaccines comprise Covid virus proteins that can be injected
into the subject’s body. These include CoronaVac, the Zhifei vaccine and
Novavax. There are several more.
Why
not use these old-tech vaccines to control the Covid pandemic? Why go
for modern technology that hasn’t been properly assessed and that might
have serious side effects in the medium to long term?
*Don’t be naive*
The
insistence of many vaccine manufacturers on indemnity clauses in the
agreements with governments is clear evidence that the manufacturers
themselves too are not able to exclude serious medium or long-term side
effects.
We would be
extremely naive if we do not note the profit motive when evaluating our
national vaccine strategy. Vaccine manufacturers stand to make humongous
profits if their vaccines are used on a worldwide scale. With the
indemnity clause in place, they are shielded from litigation if anything
goes wrong.
We have to
be world-wise and factor in the tremendous influence that the large
pharmaceutical companies have over governments and regulatory
institutions in the West.
We
also have to factor in geopolitical biases when evaluating Western
media often disparaging news reports of non-Western Covid vaccines.
A cautious approach
Malaysia
is not in as dire straits as the US or the EU countries where the
failure to implement physical distancing measures has led to the current
horrendous levels of infections and hospitalisations.
*We
are not doing so well now with our new cases edging up to 2,000 per
day, but our rates are much lower than in many other countries.*
*Covid
is not a health emergency that is threatening to overwhelm our medical
services as is the case in several Western countries. So we do not have
to take desperate measures.*
Based on the above considerations, my friends and I would like to suggest the following:
Rely
on the _'old-tech' vaccines_ that inject viral protein into the
subject. Let’s not experiment on our population with the ‘canggih’
vaccines that use the new RNA and DNA technology, whose medium and
long-term adverse effects are at present unknown.
Offer
the _'old tech' Covid vaccines_ to the high-risk groups initially – eg
healthcare workers, other frontliner personnel, older people, people
with comorbidities (other health problems) – and then later to the
entire population. But do not make it mandatory for any particular
group. Let people make an informed choice.
Provide
clear information to the public. All vaccines have side effects and the
public have a right to know of these. Given the level of mistrust of
authorities in the West, some of the doubts expressed there will filter
over to Malaysia. The best way of dealing with this mistrust is by being
honest with our people. The authorities should tell the people what
they know, and also what we still do not know about these vaccines.
Provide the _'old-tech' Covid vaccines_ free to the population.
Conduct
post-Covid vaccination surveillance to obtain an accurate estimate of
symptoms and side effects arising from the vaccine.
Communicate these findings to the people so they can make an informed choice regarding getting vaccinated.
The
Ministry of Health is in the midst of conducting an opinion poll to
ascertain the Malaysian population’s stance regarding the Covid vaccine.
This
is the opportunity for civil society groups and concerned individuals
to voice up and call for a cautious and measured approach to the mass
vaccination of the Malaysian population.
