According to National Geographic, a team of scientists is currently developing a ‘self-expanding vaccine’ that can infect non-vaccinated people or non-vaccinated animals by vaccinating others.
The test was designed to spread the vaccine to non-vaccinated people in the vicinity of the vaccinated person.
“The idea is that instead of having a vaccine in a person’s body, the vaccine itself will infect them in such a way that they can vaccinate others around them, just as they would otherwise transmit a disease. Scientists can vaccinate an individual or an animal in a community and the vaccine will spread to people around them, ”according to Newsbreak.
Scientists are currently developing a “contagious vaccine” for Ebola, bovine tuberculosis and Lhasa fever, a viral disease transmitted by rats, the report said.
Scientists plan to expand their research into other zoonotic diseases, including rabies, West Nile virus, Lyme disease and plague.
Vaccines use cytomegalovirus (CMV), a group that belongs to the herpes family. According to the Mayo Clinic, once infected, your body retains the virus for a lifetime.
“CMV is spread from person to person through body fluids such as blood, saliva, urine, semen and breast milk. There is no cure, but there are medications that can help treat the symptoms. “
National Geographic reports:
Imagine a remedy that is as contagious as the disease it fights — a vaccine that can replicate in the host’s body and spread to others in the vicinity, quickly and easily protecting the entire population from germ attack. It is the goal of several groups around the world who are reviving controversial research for the development of self-expanding vaccines.
Researchers are currently developing a vaccine for Ebola, Bovine Tuberculosis and Lhasa Fever, a viral disease transmitted by rats that causes more than 300,000 infections annually in parts of West Africa. The method can be extended to target other zoonotic diseases, including rabies, West Nile virus, Lyme disease, and plague.
Advocates for self-spreading vaccines say they could revolutionize public health by preventing the spread of infectious diseases in animals before a zoonotic spillover occurs – potentially preventing a subsequent epidemic.
But others argue that the viruses used in these vaccines could mutate on their own, jump off species, or create a chain reaction with devastating effects across the entire ecosystem.
Jonas Sandbrink, a biosecurity researcher at the Future of Humanity Institute at Oxford University, says, “Once you set yourself between an engineer and something self-transmitting, you never know what will happen and where it will go.” “Even if you start by setting it up in animal populations, a fraction of the genetic material can find its way back into humans.”
Vaccine work is underway
New interest and funding for the technology rose in 2016, and today several research groups are developing self-expanding vaccines for animals.
Each of these new vaccines is a so-called recombinant virus. The researchers first identified a protein from the target bacterium that acts as an antigen – a substance that triggers the immune response in vaccinated humans or animals. The researchers then selected a virus to carry the vaccine and spread it. To do this, the researchers isolated a few animals from their target population প্র primates for Ebola, rats for Lhasa fever এবং and a virus that naturally infects those animals. They then split the genetic material from the target to create a vaccine.
Each of these vaccines uses a cytomegalovirus, or CMVs, a group that belongs to the herpes family.
CMVs help researchers overcome a variety of technical challenges. For one, CMVs have large genomes made from double-stranded DNA, meaning their genetic code could accommodate extra genes from more stable and targeted germs, said Alec Redwood, a lead research fellow at the University of Western Australia. He conducted self-expanding vaccine research in the early 2000s and is now part of a team developing a CMV-based Lhasa fever vaccine.
To date, no field or laboratory research has been conducted to evaluate the effects and safety of these vaccines supplied through self-propagation. However, a recent mathematical modeling study reported that if it works as expected, releasing the Lhasa fever vaccine could reduce the risk of disease transmission in rats by 95 percent in less than a year.
