Coronavirus Disease : Vaccines

Gravitas: 3 companies. 2 Covid-19 vaccines. $34 Billion in profits

There are several COVID-19 vaccines validated for use by WHO . The first mass vaccination programme started in early December 2020 and the number of vaccination doses administered is updated on a daily basis on the COVID-19 dashboard.

The WHO Emergency Use Listing process determines whether a product can be recommended for use based on all the available data on safety and efficacy and on its suitability in low- and middle-income countries. Vaccines are assessed to ensure they meet acceptable standards of quality, safety and efficacy using clinical trial data, manufacturing and quality control processes. The assessment weighs the threat posed by the emergency as well as the benefit that would accrue from the use of the product against any potential risks.

In line with their national regulations and legislation, countries have the autonomy to issue emergency use authorizations for any health product. Domestic emergency use authorizations are issued at the discretion of countries and not subject to WHO approval.

As of 26 November 2021, the following vaccines have obtained EUL:

If you live in a country where vaccines are available to more people beyond these priority groups, get vaccinated as soon as it is your turn.

Mrna Flu Shots Move Into Trials

Hot off the successful deployment of mRNA vaccines for the prevention of COVID-19, three leading drugmakers have moved seasonal flu vaccine candidates built with the technology into early clinical testing. More companies intend to follow their leads next year .

These candidates, if successful, could dramatically bolster the efficacy of a vaccine class that often delivers lacklustre protection. For mRNAs proponents led by Moderna, Pfizer and Sanofi, all of which initiated phase I trials in recent months new flu jabs could prove lucrative or help maintain standing in a global market projected to exceed US$10 billion by decades end.

A New Shot Every Year

Flu shots are necessary every year, but they dont provide flawless protection. One study found that, every 28 days after receiving a flu shot, the risk of catching the virus increases by 16%. The flu viruses mutate so often and so quickly that creating a new vaccine every year is the only way to stay ahead of it.

Studies show that booster vaccines can improve the efficacy of the vaccine, but only for limited demographics. Similar to the COVID-19 vaccine, researchers are finding that those with already-limited immune systems who dont develop an immune response as effectively might benefit from a second flu vaccine.

    How Do Vaccines Work

    Getting vaccines for various preventable diseases is an expected part of childhood in most of the developed world. But how do these vaccines work?

    When the human immune system encounters a virus or bacteria that might make the host ill, it creates antibodies that attach to the antigens on the outside of the virus or bacteria cell. These antibodies train the immune system when and where to attack. Under normal circumstances, the body produces antibodies anytime it gets sick. But with some severe illnesses like diphtheria, tetanus, and measles, where infections can have severe side effects or be fatal, thats where vaccines come in.

    Vaccines work by introducing a small, weakened or inactive antigen from a specific illness into the body. The immune system can create antibodies that will recognize the specific pathogen if they ever encounter it in the real world, without having to get sick in the first place.

    Most vaccines offer extended protection. The vaccine that prevents tetanus, for example, is only necessary once every 5-10 years, though studies show that the antibody levels dont drop significantly over the course of a persons life, so boosters are only necessary for the event of a severe injury, surgery, or animal bite.

    With all these levels of protection, what makes flu vaccines so different that a new formula is necessary every year?

    How The Seasonal Flu Jab Is Made

    Radio 4 You and Yours Reporter

    It sounds unlikely, but you can’t make a flu vaccine without breaking a few eggs.

    The only manufacturer of the flu jab in the UK is Novartis, based Liverpool – which makes 30 million of the jabs a year for the global market.

    Chickens play a crucial role in the process.

    Hens’ eggs began to be used to grow the flu virus in the 1940’s because they provided the right conditions and nutrients.

    Five drug companies now manufacture the world’s flu vaccines and 70 years later all of them use eggs to grow the vaccine.

    The NHS buys nearly 16 million doses a year.

    He said: “Twelve times a day we get a delivery of 12 trolleys full of eggs. Each trolley has 5,500 eggs, so half a million each day. They stay in a warm room which is kept at constant temperature of 20 degrees Celsius.”

    Development Of Candidate Vaccine Viruses

    • In general influenza wild type A viruses recommended for inclusion in vaccines do not grow efficiently in eggs for large scale production.
    • Two technologies are being used for the development of suitable candidate reassortant vaccine viruses:
      • classical reassortment, available since 1971 to generate hybrid viruses.
      • reverse genetics, a patented technology, available to attenuate highly pathogenic viruses and reassort the attenuated HA and NA with backbone virus.

    But Theres More About Vaccine Profits

    How Israeli Company BiondVax is Creating a Universal Flu Vaccine

    Actually, there are other issues that become problematic if we suddenly had this size of an epidemic. For example, the number of ICU beds per capita has dropped by 75% since the 1960s partially as a result of the reduction in numbers of children with infectious diseases. See the irony there?

    If we suddenly stopped vaccinating because Big Pharma wanted to make billions of more profits, our hospitals would be overwhelmed. And guess whos making money then? Big Mortuary. Because children will die at much higher rates than in the 1950s because we couldnt handle it.

    And Im ignoring all of the other burdens to modern countries if this happened. Parents who are unable to work. Long-term healthcare costs for children who are seriously injured by these diseases. Emotional stress. Overwhelmed hospitals that cant treat other chronic conditions. Even countries that have superior healthcare systems would collapse under the strain.

    So, all of you people at Age of lying about Autism , how much money are YOU receiving from Big Pharma to create the illusion that vaccines are dangerous? Because, now I have uncovered the real goal of Big Pharma get rid of vaccines. Yes, obviously anti-vaxxers are the real shills for Big Pharma. How unethical can they be, sacrificing the lives and health of children for a few dollars from Big Pharma?

    Is Big Pharma perfect? Hell no, and Ive said it before.

    Gsk Surprised By Demand

    GSK won FDA approval for its quadrivalent vaccine, Fluarix Quadrivalent, in December 2012 for use in those 3 years of age and older. The company plans to make 22 million to 24 million doses of vaccine this year, including up to 10 million doses of the four-strain version.

    Rob Perry, GSK US external communications director for vaccines, said demand for Fluarix Quadrivalent has been surprisingly strong.

    “We pre-booked every dose of Fluarix Quadrivalent that we could manufactureapproximately 10 million doses,” Perry said by e-mail. “What surprised us about the demand was that it played out despite our not beginning to take orders until almost February, which is toward the end of booking season.

    “We attribute the demand to healthcare providers quickly recognizing the benefit of offering their patients a flu vaccine that includes a second B strain, as well as the quick signal from the ACIP meeting in February that quadrivalent flu vaccine was an appropriate alternative to traditional trivalent flu vaccines.

    “CDC, always our single largest flu vaccines customer, placed a major order for Fluarix Quadrivalent, and healthcare providers moved in the same direction. Candidly, GSK originally projected that demand for quadrivalent vaccines would take a few years to build, though the simple logic of quadrivalent flu vaccine has always made sense as we were working to develop it.”

    Medicago Building Vaccine Factory In North Carolina

    A small Quebec-based company is experimenting with a faster and cheaper way to make flu vaccines as part of the U.S. government’s program to fight biological threats, including pandemics.

    The U.S. Defence Department is investing $21 million US in Medicago, a company that is researching how to make flu vaccines with tobacco plants.

    During the H1N1 outbreak, Medicago did a test run of producing the experimental vaccine in Australian tobacco plants.

    “It took approximately 19 days until we were able to have the first doses of the vaccine,” said Medicago’s chief scientific officer, Louis Vezina.

    In comparison, the traditional approach of growing flu vaccines in eggs took six months.

    Handling And Storing Vaccines

    Vaccines must be handled carefully by trained personnel from the time they are made to when they are given to patients. This ensures Canadians have a steady supply of safe and effective vaccines.

    Vaccines may become less effective when exposed to sunlight and extreme temperatures. Most vaccines must maintain a temperature of between 2 to 8°C at all times. If the product is ever exposed to temperatures outside this range, the vaccine may have to be destroyed. This waste could mean there may not be enough vaccine for those who need it.

    In partnership with the GC, the Canadian Nurses Coalition on Immunization developed the National Vaccine Storage and Handling Guidelines for Immunization Providers. These guidelines describe the:

    • temperature range for keeping vaccines
    • responsibilities of personnel handling and storing vaccines
    • right equipment needed to store vaccines safely
    • best practices for stock management, including vaccine distribution and disposal guidelines

    Pigs Pandemics And A Better Vaccine

    RTP company using plants to make flu vaccines

    But even the most effectively formulated seasonal flu shot is, by design, only intended to protect people from the types of flu that commonly circulate in humans.

    Among researchers, another main area of concern is the possibility of a flu pandemic, which occurs when a flu virus that typically infects animals, like pigs or birds, changes in such a way that it can spread rapidly and perhaps lethally from person to person.

    That’s where experts like veterinarian and professor Andrew Bowman, who leads Ohio State University’s animal influenza research program, come in.

    Bowman and his team spend each summer traveling to more than 100 county fairs, where they swab the snouts of exhibition pigs in search of flu strains with pandemic potential. Much like the CDC researchers who analyze human flu specimens, their goal is to use genetic testing to get an early look at potentially troublesome changes in the viruses they capture.

    “As we characterize these strains, we can identify viruses that might be able to spread human-to-human so that we can have effective countermeasures in place before … an outbreak, Bowman says. These countermeasures include collaborating with the CDC to have the building blocks of a pandemic flu vaccine at the ready, should the need arise.

    But it doesn’t take a pandemic for the flu to be a serious, even fatal, health threat especially for older adults.

    Innovation For Flu And Beyond

    We are pursuing next generation influenza vaccines with multiple vaccine technologies to develop and bring forward tomorrows vaccines to people around the world as fast as possible.

    That means not only using mRNA or protein-based technologies, but also of antigen selection in order to induce broader protection.

    We are currently innovating in our existing different technologies including egg-based flu vaccines, recombinant proteins, mRNA to develop and deliver vaccines that can protect as many people as possible against flu and its complications.

    How The Flu Vaccine Is Made

    • The flu vaccine contains three or four strains of flu type A and B viruses.
    • These viruses are injected into eggs or added to cell cultures, where they’ll grow and multiply.
    • After that, the viruses are killed or weakened for the vaccine.
    • This article was reviewed by Graham Snyder, MD, MS, who is the medical director for the Infection Prevention and Hospital Epidemiology branch at University of Pittsburgh Medical Center.
    • This story is part of Insider’s Flu Shot Guide.

    For the 2019-20 flu season, more than 162 million doses of flu vaccines will be made in the US, alone.

    The flu vaccine may only be widely distributed during certain months, but creating it is a year-round process.

    These vaccines are the result of months of careful research and planning to produce the most effective vaccine possible. Here’s the process from start to finish.
