The first person to receive an experimental vaccine against plague as part of a medical trial last summer was inspired by the thought that his involvement could help to rid the world of one of the most brutal killers in human history.
They made it clear that I was the first person to receive it. It's a big honor to be the first, but there are risks. He was fine within three hours after feeling unwell that night, and the small trial continued on to combat the centuries-old bacteria threat, which killed 171 in Madagascar as recently as 2017). It uses a weakened version of a common-cold virus from Chimpanzees.
It is one example of how scientists are looking at how Covid treatments can be used to treat other diseases. Trials are expected to be developed for other jabs against a lot of pathogens. Humans are going to be part of another vaccine study. Professor Sarah Gilbert, architect of the Oxford Vaccine, has said that they can put a cherry on top or add some pistachios if they want a different vaccine.
The Covid outbreak led to a global shutdown to contain its spread. Billions of dollars in public and private money were spent on research in a short period of time. It is not something the medical world would have chosen, but the developments of the past two years could not have happened without Covid-19.
The lessons that have been learned will change medical science forever. Thanks to the growing research into hi-tech vaccines, which could benefit patients with cancer and a whole raft of infectious diseases, the world is on the verge of a number of potentially significant breakthrough. New studies into long Covid could show a light into blood, myalgic encephalomyelitis/chronic fatigue syndrome, and other conditions associated with the stubborn virus. Increased cross-border collaboration could soon reap rewards, as Obesity and vitamins are under the microscope.
The rapid translation of previous knowledge into practice is stimulated by covid. It could take a decade or more for a new vaccine or drug to go through all the development and regulatory stages, until Covid provided an easier regulatory environment.
Five years ago, there was a lot of hesitation to invest in experimental drugs that use synthetic molecules to guide human cells into making specific proteins that can defend against diseases. Within two years, the rapid development and success of Pfizer/BioNTech and Moderna's jabs against Covid, no product based on the technology had ever been approved.
Pfizer was working with a German start-up, BioNTech, on a flu jab before Covid came along. The focus shifted to developing a vaccine for the Pandemic and the need for a treatment to be created to be created quickly.
Richard Bucala, the Yale school of medicine chief of rheumatology, allergy and immunology, says that the vaccine technology has been researched for at least 10 years. It is extremely risky. People don't want to be involved in research and development. You don't know it's a failure until you're in a trial. The success of RNA tech changed everything.
The public's acceptance of an unusual hi-tech approach has been key, and approval by a variety of regulatory bodies has given both investors and industry confidence. If the new jabs impress in trials that are being prepared for humans, this could open the door to further approvals.
Almost half of all people have died from Malaria since the Stone Age, and they have their sights set on it. More than 600,000 people died from infectious disease last year.
The team from Bucala collaborated with the pharmaceutical company to develop a jab for it. The technology stems from a vaccine that was developed at Yale. Within two years, it could be tested in humans.
He says that self-amplification can be used to protect against a range of tropical diseases. In the next five to 10 years, this will unfold.
Moderna began their trial for an HIV vaccine that uses the same technology as the Covid jab at the beginning of February. lifetime protection will be offered by a one-off jab if they succeed. This technology is being studied to see if it can help control diseases that are resistant to treatment, such as cancer of the colon, skin, breast and other parts of the body.
Professor David Diemert, an immunologist at George Washington University, says that the Covid pandemic really demonstrated the success of mRNA vaccines. The path from discussing its application for HIV to a Phase I clinical trial was accelerated. This procedure is unique to vaccines. Moderna alone is developing trials for at least another 30 mRNA-based treatments in six different areas of medicine.
More attention has been given to how to tackle Obesity since it has emerged as a leading factor related to Covid. The FDA approved the first Obesity medication in June. A study of nearly 2,000 patients showed that wegovy could be up to twice as effective as previous weight-loss drugs.
The synthetic version of a hormone that reduces appetite was already used in lower doses to treat type 2 diabetes, but it was approved by regulators because of growing evidence that weight loss reduces Covid severity. The availability of a drug that can improve both blood sugar and body weight could have far-reaching effects on public health, especially for people who have remained overweight despite their best efforts.
This will open the floodgates for new jabs that impress in trials
Covid has shown the potential benefits of vitamins D and E. The publication of a paper in a journal co-authored by dozens of experts suggests that deficiencies in the body's ability to produce the sun's rays could be a root cause of many diseases.
It said that genetic analyses provided strong evidence for an inverse association with all-cause mortality for people with deficiency of vitamin D.
Digital health has come to the fore as a result of the Pandemic. This has come with rapid clinical evaluation.
ME/CFS is one of the long-term conditions that is being thrown more light on by the research into long Covid. The need for further understanding has become even more pressing due to Covid, and Resia Pretorius, head of the physiological sciences department at Stellenbosch University, South Africa, has been exploring microclotting for a long time. The model suggests that small blood clot in blood capillaries may cause long-covid symptoms.
Pretorius is leading a study to understand if microclotting could help uncover the mystery of long Covid after research in her lab detected significant formations among patients. The preliminary results of her research suggested that anti-clotting treatments could help.
Preto says there might be a point of no return for many ME/CFS patients if you don't treat early in the disease. We think the reasons why people develop long Covid from a viral infection could be similar to why people develop ME/CFS.
Pretorius has been impressed by the increasing degree of academic and research collaboration, with Covid unifying people from across the globe in a common goal that could endure.
The move towards scientific collaboration and the impressive advances that have emerged in a relatively short space of time is one area of optimism.
