It is a well-known fact that the incidence of corona is the highest in the United States among all the countries in the world. Whether it is due to the public that do not listen to reason or the government that is in disarray is a topic with enough fodder for endless debates. Globally, Covid-19 has infected 71 million people so far out of which 1.6 million people have died. The United States alone has contributed 16 million cases and 300 thousand deaths! When you consider the fact that the US population is only 5% of the world population and still there are more than 3,000 Covid related deaths occurring in this country each day these days, the seriousness of these numbers become terrifyingly apparent.
Despite the dire situation, many people, not only in the United States but also in India, have said that they will not get vaccinated for various reasons related to politics, policy, boredom, apathy and skepticism. Is such reluctance appropriate or reflects irresponsibility? There is an urgent need to analyze what kind of myths and rumors skeptics are listening to that are flowing in via the various media, including FB and WA forwards. It goes without saying that if the concerns are appropriate, they should be addressed correctly.
There can be no doubt that the quality of our lives has improved significantly thanks to vaccinations over the past one hundred years. The progress made by the industry is one of the main reasons why we now encounter diseases such as polio and smallpox only on the history books. Most of the vaccines we know carry small amounts of dead or inactivated pathogens into the human body. They do not bring the disease into our body because the specific pathogen is killed or inactivated during the preparation of the vaccine. But the genomic signature, which is like the face of the parasite found in the vaccine, awakens our body's immune system and prepares the body to fight the disease. Because of this immune response, when we are vaccinated against the flu for example, it is natural for us to have a body ache and fever, as if we had a mild case of flu itself. Because what came in was a inactivated virus, the body returns to normalcy in a day or two without the inconvenience becoming anything bigger. But since the body has thus been trained to recognize the invading pathogen on sight, if the real pathogen ever comes in, it quickly fights back destroying it while saving us from the disease. We can see the vaccines that work in this way as law enforcement personnel who bring the "Wanted" poster of a criminal or terrorist and stick it inside us. Since what was brought in is just a poster and not the real terrorist, we just get to familiarize ourselves with the terrorist's face. The mild fever that lasts for couple of days, can be equated to the town’s people looking at the wanted poster getting excited shouting out, “Ah.. Is this the terrorist? If he ever shows up in this town, we will promptly get rid of him!” as they go through preparatory exercises to get ready for the fight.
Manufacturing and distributing vaccines of this kind around the world is tantamount to printing
millions of Wanted posters of the terrorist and distributing them around the
world. While this is a well-known process, it takes a lot of time to physically
print and distribute millions of posters, pasting them on town squares and
ensuring the localites familiarize themselves with the face and remain vigilant.
For example, it is still necessary to run virus farms in chicken eggs for about
six months to produce the required amount of flu vaccine each year using this biological
manufacturing process. What if instead you could just send an e-mail to every
town with a note on how to print the image of the terrorist and tell them to
print it out locally and hang it up in the town square? This is the model
followed in the new mRNA (Messenger Ribonucleic Acid) vaccine development
process. Although this mRNA method was introduced ten to
twenty years ago, the corona vaccine is the first attempt to implement it on a
large scale.

Decades back when we were growing up, Tamil magazines that
used to get delivered on a weekly cadence used to carry serials that will deliver a long story in
installments spanning a whole year. There
were famous artists like Jayaraj and Maniyam Selvam who will pick up the details
of the story characters or scenes from the author’s descriptions and create
very nice looking illustrations to go with the published stories. In an
analogous scenario, instructions for how to build our body parts like an ear or
a nose are delivered to our body via these mRNA instructions derived from the
long strands of DNA. Our bodies, like those artists, can read these
instructions and create the needed parts. Scientists explore the Covid-19
horoscope (i.e. the genome of the virus), to determine which segment should be
used as its signature (i.e. mug shot in the wanted poster). They then make that
sliver into something like a jpg computer file that is equivalent to mRNA
instructions. Similar to emailing the jpg file to individual towns and asking
them to print and hang the posters using local printing presses, these mRNA
instructions are placed in the vaccine and injected into human beings. Once the
mRNA instructions are in hand, just like the illustrators that create the
drawings, our body will get to work to produce the virus inside our body. But since
the mRNA messages do not give the details needed to fully create the virus, but
only the details of the face, the construction stops with the mug shot found in
the Wanted poster in place of the real-life three-dimensional virus. After a mild
round of rabble rousing (i.e. light fever, body aches), the villagers get ready
to chase the extremist whenever he actually shows up in the town. Like
traditional vaccines, this type of vaccine is usually given twice, with an
interval of a few weeks in between. This is equivalent to the sheriff deputy returning
to the town a month after posting the poster in the town square to update the
poster/mugshot and reminding the town folk yelling, “Don't forget this
extremist. Is everyone ready?” If you don’t do that, people may become busy
with their daily lives and forget the importance of fighting the terrorist
altogether.

As we can easily see, there is no need
to incubate the chicken eggs for six months to grow the virus in this mRNA
vaccine manufacturing process. Because the vaccine we send into the body is
only for the preparation of the face of the virus within our body, the chemical
compounds containing those instructions can be easily and quickly produced in
abundance. The problem is that these mRNA instructions remain very fragile and are
very easily destroyed after being made. You can casually wrap paper posters
into a bundle, carry them on the back of a bicycle and stick them anywhere with
simple glue. But when you are handling computer files, you are forced show some
respect. Right? Otherwise file may get corrupted making it completely useless.
Similarly, these mRNA vaccines have to be kept in deep freezing temperatures as
they are transported. If not, it promised to break up quickly becoming a bucket
of useless water within hours.
The Covid-19 vaccine, which is now in
its final stages of mass distribution getting loaded on trucks and aircrafts
for transportation, has been introduced by three companies. Pfizer's version of
the drug should be kept at -70 degrees Celsius and Moderna's at -20 degrees
Celsius. We can say the -20 degrees Celsius is not that far off from our home
refrigerator’s freezer. But -70 degrees Celsius is less than the temperature of
the Antarctic ice sheet. The big puzzle that needs to be resolved is whether
machines that maintain that low temperature could be made readily available
around the world. On the other hand, they are now looking for answers to
questions such as how quickly the drug should be loaded into the hands of
people when the fridge is opened and taken out, and whether it can be taken out
of the freezer and kept in the refrigerator for few days. The current
understanding is that the drug will remain intact for up to six months in the
freezer and once taken out of the freezer it will remain effecive for about
five days, if it is refridgerated properly. Since these vaccines cannot be
relied upon to be dispensed at regular drug stores, Pfizer plans to pack the
vaccine into boxes that hold about one thousand vials, make freezers to maintain the required
ultralow temperature, pour tons of dry ice on its head and load it onto planes
to ensure the cold chain is never broken.
If you start digging into details, you will come across other logistics related
issues. For example, if we set the home A/C at 72 F degrees at home, the room temperature
will not be exactly 72 degrees. The system starts to run when the temperature
touches a 75 degrees and stops when the temperature reaches 69 degrees. When the
systems runs this way repeatedly, we know that the room temperature will be 72
degrees on average. That 69 - 75 degree difference is called Hysteresis. This
is how everything from our refrigerator to the freezers in most hospitals work.
Since this delicate mRNA vaccine has to be treated like a VIP, it can increase
the need for freezers that do not do this periodic cycling but maintain exactly
the same temperature without any oscillation. This freezer demand will add to
the cost of distribution until we develop enough expertise in managing this
supply chain smoothly. On another logistics front, medical institutions need to
train physicians and nurses who are goin to deliver the vaccine on precise
equillibration procedures, so that the drug is taken out of the fridge/freezer
at the right time to bring it up to room temperature before it is injected into
someone’s arm. This time will be different for different company vaccines. If
the vaccine is injected a little too soon not paying attention to these
procedures, the cold drug may cause a lot of muscle pain and cramping
unnecessarily. There are quite a few logistical issues
involved in getting these vaccines delivered into people’s arms, particularly
on the last mile. Hopefully the entire world will stand up to meet the
challenge.

The vaccine, developed by Astra-Zeneca with the help of
Oxford University, is a slightly different version of the old model we saw
earlier. In this method, a virus found in a chimpanzees called the adenovirus
is used as the vehicle to carry the face of the Covid-19. As the figure above shows, the Covid genetic
code is implanted on the inactivated adenovirus, which is then injected into
the body as the new vaccine. That original adenovirus is a harmless one that
only gives mild colds to chimpanzees. It does not bother human beings at all.
Therefore, it can be considered as the equivalent of an inactivated virus. As we
implant the Covid-19 (called SARS-CoV-2) face in it, our body gets to recognize
the Covid mugshot brought in. As in other cases, this helps our body develop
immuno response that may still result in mild fever/body ache but then provides
the needed corona resistance in case if we encounter the virus in future. Since
it uses an inactivated virus without depending on mRNA method, no deep freezing
is required. Regular refrigeration will do. Russia has announced with a lot of
chest thumping that it has developed a vaccine of this kind called Sputnik-V. The
vaccine developed by China follows this well-oiled adenovirus groove as well. Since
they eliminate the deep freeze temp requirements, these vaccines are likely to be
far cheaper and less complex when it comes to distribution worldwide using
regular refrigerator that are more easily available. Of these variations, test
data on the Sputnik-V vaccine are not widely available, creating skepticism in
the medical community that wonders if Putin is trying to pull a fast one for
national pride related reasons. There have also been news articles saying due
to unexpected side effects, anyone taking Sputnik-V vaccine is required not to
consume any type of alcohol for two months, Putin is reluctant to take the
vaccine himself, etc. Hopefully all that is not true so that cheaper vaccines
can be made available worldwide.
There are a lot of protocols and
procedures in place to ensure vaccines work properly and there are no serious side
effects. The first, second, and third stages of clinical trials require,
respectively, few, many, and several thousands of injections to be given and
the receivers monitored closely for several weeks. In the Western clinical
trials, double blind studies for the gold standard to assess efficacy of new
drugs. Assume that one thousand people participate in a drug test. Half of them
(five hundred participants) will be given the drug to be tested and the other
five hundred will be given a placebo that looks like the medicine. No one among
the participants would know know who is being given the drug and who is just
receiving the placebo. Even the physicians or nurses that deliver the drug
wouldn’t know who is getting what. The data collected in this way will naturally
be pure and unbiased. A separate team of researchers who receive the tables of
data without any individual identified, then analyze the numbers to see if the
people who got the real medicine actually survived the disease better compared
to those who got the placebo.
If it is a new
drug is a therapeutic meant to treat cancer, drug trial conductors will select
many of the patients suffering from that particular type of cancer, test the
effectiveness of the new drug by giving the new drug to one half and placebo to
the other half. Everyone who participates in the study will definitely have the
disease. But when we are testing a vaccine, it is not possible to catch and
test patients who are already suffering from the disease. So, in the third
phase clinical trials, a really large number of civilians are selected and half
are vaccinated while the other half are given a placebo. Then all the
participants are monitored for several weeks to compute the rate of infection. More
than ninety-nine percent of those participants are not going to get infected
anyway, since Corona infection rate in the general population tends to be less
than 1%. Testing them by trying to infect them will be inhumane and a human
right violation. So, the efficacy need to be assessed based on the less than 1%
of the population that may normally get infected as they go about their lives. This
is how the effectiveness of the vaccine can be measured. Thus, for example, 44,000 people took part in the third stage clinical trials conducted
by Pfizer. In a few weeks of giving 22,000 people real vaccine
and 22,000 participants a placebo injection, a total of 94 people were found to have been infected. When the data was
analyzed by another team not involved in the trial giving away the vaccine, they
estimated that the effectiveness of the vaccine was over 90
percent. It can be understood as follows. If 47 of those 94 people had been in the real vaccine group and the remaining
47 on the placebo group, it would have been concluded that the drug was of no
use. Instead if no one in the group that received the real vaccine became ill,
the drug would have been concluded to be 100% effective
for the sample population participating in this study. In reality about 91
people who were infected had received the placebo while only about 3 that
received the vaccine got infected. So, the efficacy is computed to be north of 90 percent. It should be interesting to note that due to this
nature of vaccine testing, even though 44,000 participants were involved in the
study, 10 more cases falling one side or
the other will swing the efficacy rate considerably.
The questions
or confusions posed by skeptics of these vaccines can be categorized into about
eight different kinds. Answers based on our current understanding that
addresses these points are listed in parenthesis:
1. This is a new
type of vaccine meddles with our DNA. It can modify the core of who we are and
can affect all of our descendants. [As discussed at length above, the idea that this new
vaccine could modify our DNA, transforming us and our descendants into some
other being is highly imaginary. So far there are no rational reasons to be
afraid. We saw that common vaccines usually send inactivated pathogens into our
body to trigger an immune response. This mRNA method may be considered even
safer over time, as these vaccines inject only the instructions to create the
signature of the pathogen. The polio vaccine introduced in the 1960s,
had a horrible incidence where accidentally live polio virus (instead of the
inactivated version) was included in a batch of the vaccine that got shipped
out. This manufacturing blunder resulted in many vaccine recipients getting the
disease instead of getting protected against it. Though it occurred decades
back when the whole vaccine technology was fairly new, it was certainly a
horrible mistake. But since mRNA vaccines don’t contain pathogens but only
instructions to create their signature, such mistakes can’t happen in this
model. ]
2. Because the
economy is collapsing, just people are being tested to declare the vaccine safe
to allow the businesses to reopen. They say it usually takes six years to
develop a vaccine. But the corona vaccine was made in just six months? [It is true that this vaccine is coming
to the market very quickly compared to other traditional vaccines. But when
data collected from experiments are published to be readily available to
everyone, we need not worry unnecessarily. How is it fair to say that vaccine
production should not be accelerated while the entire world is in a semi
shutdown state for close to an year? If it takes 5, 10 years to complete the process, do we want the world to be on
hold for that long? Since that is not practical, Governments and drug companies
have come up with a number of steps (at a huge cost) to speed up the process.
Thus, companies started large scale manufacturing of the vaccines still being
tested in the hope that testing will go well and the governments will grant
permission soon. If permissions are not issued, or if the drug is finally found
to be ineffective, multibillion dollars worth of medicine will have to be
dumped in the trash. Doing so at other times will result in the entire loss
falling on the head of the pharmaceutical company and the company going
bankrupt. Therefore, companies will not start production until permission is
obtained. Since governments have offered to accept losses this time around, production
could start in parallel.]
3. Should we not
ask any questions about these new vaccines? Is everything clear already? If
making vaccines is so easy, how come we don’t have a vaccine yet for AIDS?! [Questions like how long will the vaccine
immunity last, and whether the drug will protect us from it if Covid-19 mutates into new Covid-20 next, are all
valid. Answers to these questions are still a few years
away. There is nothing wrong with that. Compared to Covid-19,
the AIDS virus is even more vicious and effective. The human
immunodeficiency virus (HIV) has morphed into many incarnations due to genetic mutations. With almost a
hundred different versions of it in circulation, we are struggling to develop a
vaccine. It is also capable of hiding inside human cells, making itself
impervious to vaccines. So, while scientists are at it, it is not as easy as
reading just one virus genome and creating a vaccine as in the case of
Covid-19. We better pray that Covid-19 doesn’t keep morphing into newer avatars
like HIV in the forthcoming years!]
4. Heard that someone
in India has become so ill after taking this vaccine and has sued the drug
company in court. [According to
biological theories, every human being is unique. No drug works the same way in
everyone's body in the world. When 40,000 people are
vaccinated in the third round of clinical trials, it is possible that one or
two will experience moderate to severe side effects. It is the job of
pharmaceutical companies, scientists, and governments to take this into account
and revise the vaccine or modify the dosage. Although Aspirin, a common
headache pill, has been used billions of times a day worldwide for 40 years, its side effects can still be fatal to a new user. If
we completely ban the use of Aspirin because of statistically insignificant
instances of bad side effects, we will lose all the positive effects as well.
Similarly, even in the case of these new vaccines, it is appropriate to work on
improving the medicine and not give this vaccine to people with specific
disorders where it is found to be harmful. For example, after the initial roll
out, UK noticed that people with extreme allergies experienced a lot of bad
side effects. Though with proper treatment, they all had gotten better, UK has
advised people with extreme allergies not to take the vaccine at this time.
This is appropriate. But it is certainly not the right approach to say that no
one should be vaccinated because of a negligible number of bad side effects, no
matter how many people die.]
5. This is a
conspiracy by China/Trump/Bill Gates/Putin/pharmaceutical companies to bring
the world under their control or to make money. [Analyzing them one by one, none of
these accusations seem real. Many governments are preparing to make the vaccine
available to the public free of charge. Many governments and NGOs have warned
drug companies not to indulge in any form of price gouging. People like
Trump/Bill Gates do not seem to have benefited from these vaccines. China does
not seem to be making big money selling drugs to the world, as it seems to be
busy protecting its ownpeople. It is noteworthy that all
of the soon-to-be-released vaccines are based on the Covid-19 genetic
code published by Chinese scientists circa January 2020.]
6. OK, with all
that said, will you dare to get vaccinated once you have access to it? [My wife, kids and I are all going to
get vaccinated as soon as it is offered to us in the right order of priority.]
7. OK, now I am
convinced. Which vaccine is the best? How do I jump to the front of the queue? [If the clinical trial data clearly
shows that the vaccine is more than 90% effective and doesn’t show
objectionable side effects, each vaccine can be considered effective and safe. Since
the normal flu vaccine is only about 60% effective, the effectiveness of these
vaccines may eventually drop slightly when given to billions of people. That is
to be expected. However, a community-wide immunity called Herd Immunity can be
reached only if more than 70% of the population is vaccinated against a
particular disease and becomes immune. Because Covid-19 is extremely contagious
and so spreads so easily, it is incumbent upon us, as good citizens, to get vaccinated
when it is our turn, after correct priorities have been accorded to healthcare
workers, elderly and other special category of people.]
8. Well, I get
the idea. What should I do to help dispel the confusion in my community? [Do not forward the unverified social
media posts and claims to everyone in your WA groups or email lists. Adding a
disclaimer like “Forwarded as Received” does not absolve you of your
responsibility. Please do your own research to verify the authenticity of any
incoming story/message. In this age of social media, where shocking/threatening
negative news speeds around the world several times faster than well
researched, boring, good news clips, it is our civic duty to be the firewall
that blocks and filters out garbage stories. Take the time/effort to point out
and explain to your friends/relatives facts based on science that is free of
any political or monetary biases.]

The latest television news is that former US
presidents Obama, Bush and Clinton have announced that they will be getting vaccinated
in front of television cameras for all to see, when it is made available to
them as per correct priority. When people were afraid to get vaccinated against
polio in the 1960s, Elvis Presley's getting the shot on a television show
helped allay public fears.
If you know when Rajinikanth and Amitabh Bachchan are getting
their vaccine on Indian TV, let your friends know. It doesn't matter if you
forward it as a WA message. Only then the Tamil TV channel debates during 2022
January Pongal season can switch from “Who is to blame for this pandemic?” type
titles to “Who conquered Corona in 2021?” type topics. The world will applaud
you for you doing your part.
