Corona, the global pandemic
has already caused the loss of hundreds of thousands of lives and disrupted the
lives of billions more. As well as reducing the tragic loss of life and helping
to get the pandemic under control, introduction of a vaccine will prevent the
loss of billions to the global economy every month. Global equitable access to
a vaccine, particularly protecting health care workers and those most-at-risk
is the only way to mitigate the public health and economic impact of the
pandemic.
Vaccines save millions of
lives each year. Vaccines work by training and preparing the body’s natural
defences --- the immune system--- to recognize and fight off the viruses and
bacteria they target. If the body is
exposed to those disease-causing germs later, the body is immediately ready to
destroy them, preventing illness. Immunization currently prevents 2-3 million
deaths every year from diseases like diphtheria, tetanus, pertussis, influenza
and measles. There are now vaccines to prevent more than 20 life-threatening
diseases, and work is ongoing at unprecedented speed to also make COVID-19 a
vaccine-preventable disease.
A vaccine is a biological
preparation that provides active acquired immunity to a particular infectious
disease. A vaccine typically contains an
agent that resembles a disease-causing microorganism and is often made from
weakened or killed forms of the microbe, its toxins, or one of its surface
proteins. The agent stimulates the body's immune system to recognize the agent
as a threat, destroy it, and to further recognize and destroy any of the
microorganisms associated with that agent that it may encounter in the future.
Vaccines can be prophylactic (to prevent or ameliorate the effects of a future
infection by a natural or "wild" pathogen), or therapeutic (to fight
a disease that has already occurred, such as cancer). The administration of vaccines is called
vaccination. Vaccination is the most effective method of preventing infectious
diseases.
The terms vaccine and
vaccination are derived from Variolae vaccinae (smallpox of the cow), the term
devised by Edward Jenner (who both developed the concept of vaccines and
created the first vaccine) to denote cowpox. He used the phrase in 1798 for the
long title of his Inquiry into the Variolae vaccinae known as the Cow Pox, in
which he described the protective effect of cowpox against smallpox
Hopefully the vaccines
should be invented and hit the market in a few more months, after which mankind
may be able to fight and win over the Covid.
That would also require mass production, millions of vaccines, the manufacture,
pricing, handling, transportation, warehousing, distribution – are all going to
be big challenges. This would be new
business for manufacturers, pharma giants, distributors, logistics handlers and
Insurers too. A couple of months ago,
came the news that Lloyd’s of London, the world’s largest insurance market,
plans to begin offering coverage of coronavirus vaccine deliveries. Parsyl
Inc., a U.S. insurance technology company, has teamed up with Lloyd’s to
provide policies covering the storage and shipping of potential Covid-19
vaccines and other medicines, according to a Lloyd’s statement. Vaccine delivery can be expensive to insure
because underwriters are concerned about the risk of medicines being spoiled by
excessive heat or cold. There are possible losses due to thefts and attacks
too. The new business, known as
Syndicate 1796, was developed by Parsyl together with insurers Ascot Group and
a unit of AXA SA, broker McGill & Partners and Gavi, the Vaccine Alliance,
an international public health group that focuses on delivering new vaccines to
the world’s poorest countries.
It is further reported
that Pharmaceutical companies and health
authorities will store COVID-19 vaccines in secret locations to prevent theft
as vaccine makers plan to deploy GPS software to track distribution and plot
fake shipments to confuse criminals. Pfizer
Inc. is among the vaccine makers that will have GPS software on shipments, the
Wall Street Journal reports. The company is also planning to carry out fake
shipments in dummy trucks in a bid to confuse any potential thieves. The safeguards are being put in place amid
concerns that the highly-awaited vaccines could be stolen when being
distributed. Health authorities fear
criminal rings will try and steal the vaccine when it is being given to
prioritized groups like health care workers and before it is made publicly
available.
Moderna, another maker,
says it has enhanced security as the leading candidates inch closer to having a
vaccine. 'You are going to have people that will want
to have access to the vaccine earlier,' said Juan Andres, who is Moderna's
chief of technical operations. Glass
maker Corning Inc., which was given federal funding earlier this year to boost
manufacturing of vials to store COVID-19 vaccines, will fit its vials with
black-light verification to stamp out potential fake treatments. There are also a number of other safeguards
being considered across the country to protect the vaccine. Manufactures in
some states plan to ship the vaccine straight to hospitals and other approved
sites to prevent road stops. Empty dummy trucks and GPS locators are also an
option. Some hospitals are also
increasing security within their pharmacies. Philadelphia's Jefferson Health
hospital system has already committed to installing security cameras, cages and
keypad authorizations for freezer rooms where the vaccine will be stored.
It comes as a Food and Drug
Administration meeting on COVID-19 vaccines that is scheduled for Thursday will
discuss criteria for allowing emergency use of a COVID-19 vaccine. Pfizer Inc,
Moderna Inc and AstraZeneca could provide early analyses of late-stage trials
of their experimental vaccines as early as this month or the next. The FDA earlier this month told coronavirus
vaccine developers it wants at least two months of safety data before
authorizing emergency use, a requirement that likely pushes any U.S. vaccine
availability past the Nov. 3 presidential election. The meeting, which is open
to the public for comments, is another example of steps health regulators are
taking to assuage public distrust related to coronavirus vaccines, that are
being developed at unprecedented speed.
There are no
approved vaccines for the coronavirus, except two in Russia that are yet to
finish Phase 3 clinical testing.
Brazilian President Jair Bolsonaro
overruled his own health minister today, rejecting the announced purchase of 46
million doses of CoronaVac, a potential vaccine against COVID-19 being tested
in Sao Paulo state. Health minister Eduardo Pazuello announced the purchase on
Tuesday alongside Sao Paulos Gov. Joo Doria, a foe of Bolsonaros whose state
government is participating in the vaccines development. The cost of the
acquisition was estimated at 2 billion Brazilian reals ($360 million).
The Brazilian people will
not be anyones guinea pig, Bolsonaro said on his social media channels, adding
that the shot made by Chinese pharmaceutical company Sinovac is yet to finish
its testing phase which is true of all potential vaccines. My decision is to
not purchase such a vaccine. It is common practice for governments to purchase
doses of promising vaccines, to build a stockpile in case they are proven
effective. That investment is usually not refundable if the shot fails. Brazil
counts more than 153,000 deaths by COVID-19, second only to the United States.
The South American nation also confirmed 5.2 million cases of the disease, the
third biggest in the world, behind the U.S. and India.
Bolsonaro and Doria have
had an adversarial relationship since the start of the pandemic, with each
taking opposite stances regarding stay-at-home recommendations and restrictions
on activity. The governor of Brazils most populous state heeded the counsel of
public health experts and adopted such measures, which the president blasted,
arguing the economic fallout could kill more than the disease.
