With millions of lives online, researchers have been working at an unprecedented pace to develop COVID - 19 Vaccine. But that speed and some widely touted breakthroughs belie enormous complexity and potential risks involve. Researchers have an incomplete understanding of Coronavirus and are using technology that is largely unproven. Among many worries: handful of studies on COVID - 19 survivors suggest that antibodies key immune system proteins that fight infection begin to disappear within months. That leads scientists to worry that protection provided by vaccines could fade quickly as well. Some even question whether vaccines will really end pandemic. If vaccines produce limited protection against infection, experts note, people will need to continue wearing masks and social distancing even after vaccines roll out. Yet in an interview with KHN, countrys top Infectious Disease expert, Dr. Anthony Fauci, said hes cautiously optimistic that researchers will overcome such obstacles. We know the body can make an adequate response against this virus after two shots of vaccine being test, Fauci say. There is no reason to believe that we wo be able to develop a vaccine against it. Because early - stage trials began just a few months ago, doctors dont know how long antibodies in vaccinated people will last, he say. Scientists will get answers to some of their questions from the country's first large - scale COVID - 19 Vaccine trial, launched last week by the National Institutes of Health and Moderna at 89 locations around the country. Once we get protective response, we will see how long it last, Fauci say. If we do get as long response as we want, we can always give a booster shot. Leading vaccine candidates are based on new approaches that have never resulted in licensed vaccine. Moderna, relatively young company, has yet to produce any approved vaccines. Even more so than usual, as we create vaccines, were sailing in uncharted water, says Dr. William Schaffner, professor at Vanderbilt University School of Medicine. If approve, COVID Vaccine created by researchers at Oxford University and drugmaker AstraZeneca would be the first licensed vaccine to use virus that causes colds in chimpanzees but doesnt sicken people. Scientists use cold virus to deliver key elements of vaccine into patients ' body. In this case, virus delivers genes that instruct cells to make spike protein, which helps novel Coronavirus enter cells. Early studies show that Oxford Vaccine stimulates the immune system as intend. If the vaccine is successful, these antibodies and other immune cells will recognize and neutralize spike protein if they encounter it again, protecting people from disease. Two other candidates, Vaccine from Moderna and another from Pfizer and BioNTech, German company, were also developed with novel methods. They use genetic material from the Coronavirus called messenger RNA, or MRNA. Unlike traditional vaccines, which expose the body to viral protein to stimulate the immune system, MRNA acts as an instruction kit, telling the body how to construct proteins itself.

Moderna and National Institutes of Health quickly struck up work on a potential vaccine against a deadly new coronavirus. But the team hasnt found a pharma partner to manufacture vaccine for real - world use, top official said Tuesday. Nih and Moderna could develop Vaccine in a little over a year if all goes well, but they wouldn't be able to produce doses needed to deploy shots against outbreak,ss National Institute of Allergy and Infectious Diseases director Anthony Fauci said at an Aspen Institute panel. Thatd require a pharma partner, and so far, NIH hasnt found its manufacturer. The virus has caused more than 45 000 infections and more than 1 100 deaths. The vast majority of cases have been in China. If a pharma company were to get involve, it would have to adjust manufacturing facilities and sacrifice opportunity cost of producing profit - making shots it typically make, Fauci said on panel. It's dynamic that's very difficult and very frustrating, he add. Numerous times over years, emerging disease outbreaks have caught the scientific and medical community off guard. Pharma companies and others have routinely rushed in on R & D work, but outbreaks have tended to fade before would - be vaccine makers could develop effective countermeasures. Now, companies seem more cautious about jumping right into the next new outbreak. During the Ebola crisis, major pharma companies get burn with their investment and are now backing out of the field, Fauci said on panel. That likely reference to GlaxoSmithKline, which bought NIH - partner Okairos back in 2013 and picked up Ebola Vaccine candidates and several other pipeline programs. Last year, company exit Ebola Vaccine Research by licensing its candidates to Sabin Vaccine Institute. Another top vaccine player, Sanofi, got involved during the Zika outbreak, but its partnership with the US government led to controversy over potential vaccine pricing. Sanofi later quit collaboration. Despite the risk, Johnson & Johnson said Tuesday it is joining up with the US Department of Health and Human Services to accelerate Vaccine development against COVID - 19. Both partners are chipping in funding to get vaccine into clinic,s and the government could provide more money for further development. Alongside R & D effort, J & J is readying production facilities so that it can meet global health needs if shot is deploy. On NIH / Moderna collaboration, Fauci says the team should be able to get into the clinic in about two and half months from the time it receives initial virus sequence. Then, he expects three months of testing in Phase 1. If all goes well, team could advance to Phase 2 testing in China, which takes six to eight months. After that, group would be ready to start producing vaccines for use in the field. Production would require amount of time that is as problematic as developing the shot itself, Fauci say. That's unless team produce vaccines at risk, or before getting proof the vaccine will even work.
