T-cells also matter when it comes to protection from the virus and its new variants. Jones: It’s important to keep in mind that the more time the virus has to replicate, the more it can mutate. So, from a public health perspective, our emphasis is on increasing vaccinations. And several lab experiments—in which blood samples from vaccinated people are exposed to variants or manufactured "pseudo-virus" variants—suggest that the antibodies produced by the Moderna vaccine are less effective against B.1.351 than against the original version of the virus. Janies: There are a lot of variants out there, including a number of domestic variants that we are studying. CHARLOTTE, N.C. (WBTV) - There are a handful of variants of the COVID-19 virus that are beginning to spread around the world. For instance, a large study of Johnson & Johnson's vaccine found it was about 85% effective at preventing severe disease from the variant dominant in South Africa. This is three to four times faster than the average across the Carolinas. We test individual students only when it is necessary. "[T]he Moderna vaccine produces pretty high levels of antibodies," he said, "so there is enough antibody still to neutralize the virus.". Specifically, the researchers found that "vaccine effectiveness remains high" against the B.1.1.7 variant. Your top resources for Covid-19 readiness. "As long as case counts are high, even fully vaccinated individuals should take precautions" (CIDRAP News, 4/12; Aizenman, "Goats and Soda," NPR, 4/9; Schumaker, ABC News, 4/12; Stein, "Shots," NPR, 4/15; Choi, The Hill, 4/11; Williams, The Hill, 4/09). Right now, variants are relatively rare in the United States, but they are so good at replicating that we must use our most effective tool — the vaccine — to stay ahead of them. Sometimes the variations have no impact on the virus. The impact of the new variants on the effectiveness of vaccines is still not clear. One very small study suggested that that vaccine was almost entirely ineffective at preventing mild cases of Covid-19 against B.1.351, and a separate experiment found that it takes 86 times as many antibodies from the AstraZeneca vaccine to neutralize B.1.351 as it does to neutralize the original strain of the virus. Multiple variants of the virus that causes COVID-19 have been identified globally during the COVID-19 pandemic. We can do this for clinical samples from humans as well as samples collected from campus wastewater. However, the research that is available—although generally preliminary—suggest that several vaccines are fairly effective at protecting against both the original version of the virus and the range of variants emerging around … For instance, one study of Johnson & Johnson's vaccine—the distribution of which U.S. officials have temporarily paused—found it was 85% effective at preventing severe Covid-19 from the B.1.351 variant, which was first discovered in South Africa. In regard to our public health protocols, such as hand washing, mask wearing and social distancing, we will keep those in place at least for as long as public health guidelines indicate they are necessary. RALEIGH, N.C. (WNCN) – Researchers at Duke say at least one of the current COVID-19 vaccines is effective against two variants of the virus. Here these experts discuss COVID-19 variants and reasons the University should continue its comprehensive mitigation efforts, pursue a goal of achieving a fully vaccinated campus and remain committed to established campus safety protocols. ... our study suggests effectiveness of the vaccine remained very high at two weeks after the second dose against both variants," writes Stern. That said, Dr. Anthony Fauci, chief medical advisor for the Biden administration and director of the National Institute of Allergy and Infectious Diseases for the NIH, indicates an 85% vaccination rate should be the target. So, for students, faculty and staff, vaccinations will help us get back to normal. Gibas: In terms of mitigation efforts, wastewater monitoring will continue to be an important method for residence halls and other campus locations. AstraZeneca, Pfizer COVID-19 vaccines effective against variants, Oxford University study shows Brazil variant appears similar to UK variant in regards to impact on vaccine efficacy, the team said. "I'm basically not confident about [AstraZeneca's] vaccine at all" in mitigating B.1.351 infections, Abdool Karim said. Jones: The penetration of vaccinations we can achieve among our campus community will play a big part in determining that. All rights reserved. Importantly, the vaccine also showed effectiveness against rapidly-spreading variants, including the B.1.351 variant, which was identified in 95 percent of … Martins: There is an opportunity to determine if a strain that is more contagious or proven to have a higher fatality rate may be present on campus. There is limited research available on how currently authorized vaccines perform against the variants. Current ArticleHow well Covid-19 vaccines work against variants, according to the latest research. How are Variants Identified? We’re making a lot of copies of the genome, and running it through a machine to see if it contains any tell-tale mutations that would indicate it is a variant of interest or concern. As more Americans receive Covid-19 vaccines, just how effective are vaccines at combatting variants of the new coronavirus that are surging throughout the United States? For example, the Brazil variant seems to have characteristics that help it evade the immune system, which helps to increase the rate of reinfection. New data indicates that Johnson & Johnson's (NYSE:JNJ) one-shot COVID-19 vaccine is effective against the South Africa and Brazil variants of the … However, some preliminary research suggests not all vaccines are so effective against all variants. Since fall 2020, UNC Charlotte researchers Cynthia Gibas, Daniel Janies, Angelica Martins and Jessica Schlueter, along with Student Health Center medical director Robert Jones, have been part of a UNC Charlotte team leading the on-campus monitoring of wastewater as an early-warning system as to the presence of COVID-19 and analyzing laboratory tests from campus members suspected of having COVID or who may have been exposed to the coronavirus. A … Some virus variants get lucky and become better at transmitting themselves. If we return in the fall at full density without enough of the campus community vaccinated, the University could experience a similar outcome. However, because the vaccine doesn't have 100% efficacy, a few breakthrough infections occurred among vaccinated people—and those infections, while generally not severe, were most likely to be caused by the B.1.351 variant. Recent real-world evidence from the UK suggests both the Pfizer and AstraZeneca vaccines provide significant protection against severe disease and hospitalizations from the B.1.1.7 variant. The National Institute of Allergy and Infectious Diseases conducted the study. In addition, the fact that two vaccines have achieved about 95 percent efficacy has created unrealistic expectations about what it takes for a … Of those in the vaccinated group, 149 participants were infected at least one week after their second dose; the rest were infected more than two weeks following their first dose, but less than one week after their second dose. To increase our ability to manage the presence of both COVID and its variant strains — and protect our families and community — faculty experts emphasize that vaccination for all who are eligible is the most effective action we can take. According to The Hill, experts are scrambling to determine how well authorized vaccines perform against coronavirus variants because, in several countries, the variants are becoming the dominant version of the virus in circulation. The simple answer is yes. We are seeing components of these variants of concern appearing everywhere. The Moderna vaccine is now said to provide protection against the fast-spreading California mutations. @ 2021  Advisory Board. If variants in Charlotte become problematic, we would likely need to revert to past practices to make sure we’re not breathing on one another. The P.1 variant, first found in Brazil, may be able to evade vaccines, and can reinfect people who have had COVID-19, according to Brazilian experts. By contrast, Europe has not had an effective vaccine roll out, and as a result, they are going back into lockdowns. The P.1 variant, which was first detected in Brazil, is now the second-most prevalent version of the virus in the United States, and the country also has reported increasing cases of the B.1.351 variant, which was first detected in South Africa. Janies: Right now, we have a window of opportunity to get ahead. STATEN ISLAND, N.Y. — A new study from a Duke Health-led research team analyzed the effectiveness of two coronavirus (COVID-19) vaccines … That means it is possible you could still get COVID-19 soon after vaccination. This is because your body has not had enough time to build full protection. For the study, researchers compared almost 400 people in Israel who had been infected with the coronavirus after receiving at least one dose of the Pfizer/BioNTech vaccine with a control group of unvaccinated people who had similarly contracted the virus. "We see evidence for reduced vaccine effectiveness against the [B.1.1.7] variant, but after two doses, extremely high effectiveness kicks in," Adi Stern, a researcher at Tel Aviv University and senior author on the study, said. Jones: It’s important to keep in mind that the more time the virus has to replicate, the more it can mutate. "It is always important to keep in mind that vaccine protection is never 100%," Stern said. At this time, there is no evidence to suggest that these or any other Overall, we’re at a critical juncture and the science is clear. These mutations create a slightly different version — or variant — of the original virus. Why some Covid-19 vaccines may, in rare cases, cause blood clots, What you need to know about Covid-19 vaccine booster shots, Covid-19 roundup: What new data reveals about Moderna vaccine's effectiveness 6 months later, Weekend reads: The (surprising) benefits of daydreaming, Around the nation: CMS says health care prices can't be hidden from web searches, April 16, 2021 | Advisory Board Daily Briefing, How well Covid-19 vaccines work against variants, according to the latest research. It seems like each day there’s more bad news about coronavirus variants. Several weeks following the publication of the large real-world Covid-19 vaccine effectiveness study by the Clalit Research Institute in Collaboration with Harvard University in … However, the researchers found that B.1.351 accounted for 5.4% of breakthrough infections among people who had received both doses and just 0.7% of the infections among unvaccinated people. Amid these laboratory findings, researchers in Israel recently conducted the first real-world study—although still in pre-print—assessing the efficacy of the Pfizer/BioNTech vaccine against the B.1.1.7 and B.1.351 variants, with largely positive results. Schlueter: The Centers for Disease Control and Prevention is tracking on a national level how each of these strains is increasing in frequency across the United States. discusses vaccine effectiveness on COVID variants. Jones: It is important to understand the characteristics of each strain, including the homegrown ones. COVID-19 variants. We can be sure that all the variants currently found in South Carolina that have been labeled as the “South African Variant” are not due to people who went on safari in South Africa. To make more viruses, a copy of the code must be created. So, even if a variant circulates in the broader community, it may not impact us now as it would with a fully populated campus, which we’re anticipating in the fall. All COVID-19 vaccines available in the United States are effective at preventing COVID-19. Johnson & Johnson’s Janssen COVID-19 Vaccine: CDC and FDA have recommended a pause in the use of Johnson & Johnson’s J&J/Janssen COVID-19 Vaccine in the United States out of an abundance of caution, effective Tuesday, April 13.The Advisory Committee on Immunization Practices (ACIP) will hold its second emergency meeting to discuss J&J/Janssen COVID-19 Vaccine on April … Essentially, we isolate this material, amplify it, and run it through a sequencer. This is why vaccination is so important in controlling variants. That said, Salim Abdool Karim, an infectious disease researcher and co-chair of the Covid-19 advisory committee for South Africa, said he was not deeply concerned about those findings. Some resemble those that were originally identified in other parts of the world. Overall, the researchers found that the vaccine performed well against all the variants circulating in Israel. Moving forward, we can streamline the process by preparing samples in the testing lab so they are ready for sequencing. As UNC Charlotte anticipates a full return to campus instruction and operations this fall, the University continues to monitor COVID-19’s presence on campus. UNC Charlotte is sharing the results of campus testing with the Mecklenburg County Health Department as well as contributing to national databases on variants to support local and national public health efforts. Over the course of two days, we can process 96 samples, which means our entire process — from sample collection to sequence data deposit — is about a week. It typically takes about two weeks for the body to build protection after vaccination. Gibas: We should note that recent published research demonstrated that the currently available vaccines are effective against current viral strains but efficacy ranges depending on the variant. Gibas: Not always. Also, it is important to review what is published about these variants to know if there is more we can do to slow their spread, beyond the considerable safety measures that we are taking. By Robert Preidt HealthDay ReporterTHURSDAY, April 8, 2021 (HealthDay News) -- Two COVID-19 vaccines appear to work well against a rapidly spreading coronavirus variant that arose in … If those strains become more prevalent, we need to know how mutations change the properties and characteristics of the viruses. This is the reason it is really important for people to be vaccinated, under the consultation of their physicians, as soon as possible. By Kristi O'Connor | March 18, 2021 at 2:48 PM EDT - Updated March 18 at 9:40 PM . The University of North Carolina at Charlotte9201 University City Blvd, Charlotte, NC 28223-0001704-687-8622, COVID-19 variants and vaccine effectiveness — and our best path back to ‘normal’, The University of North Carolina at Charlotte. Learn from the top health plan resources on how to safely manage and prevent the spread of Covid-19 with our library of research on topics from provider network support to payer strategic outlook. As more people become infected, viruses have more chances to infect hosts and replicate. For example, a variant emerged this past summer (the D614G mutation) and because the associated mutations helped the virus spread a little faster, virtually all the COVID viruses we sequence have this mutation, which is different from the original virus out of Wuhan, China. There is limited research available on how currently authorized vaccines perform against the variants. Martins: Since the start, our protocol has been to keep and archive all positive COVID-19 samples taken on campus as we knew they would yield precious information from a public health perspective or in conducting research. In the J&J trial, the placebo group had 16 hospitalizations and seven deaths from COVID-19, whereas the vaccine group had none, which means the vaccine provided 100 percent efficacy against hospitalizations and deaths. All this tells us really is that the vaccine is less protective against the South African variant than it is against the regular variant. Here's what the latest research says. Inside UNC Charlotte is produced and maintained by the Office of University Communications; campus communicators, who include individuals representing academic and administrative units across the institution, also provide content. Gibas: The genetic materials in viruses are made up of a string of molecules called nucleotides, which produce a specific code that is characteristic of that virus. The vaccination rollout across the United States continues to go well, and many of the variants of concern still are not dominant here. The more copies that are made of the virus, the more likely one of these mutations or variants will be problematic. Even a less effective vaccine will keep you from becoming severely sick. Israeli health officials on Tuesday reported the Pfizer-BioNTech vaccine is at least partially effective against the potentially worrisome Indian variant of the coronavirus … Schlueter: Sequencing is the lab process that extracts genetic material and reads the underlying code. So, the presence of variants is not uncommon, across the country or locally. But sometimes they enable the variant to outcompete other versions of the same virus. Airlines are filling up middle seats again. Sometimes in making copies, slight changes or errors occur. However, the research that is available—although generally preliminary—suggest that several vaccines are fairly effective at protecting against both the original version of the virus and the range of variants emerging around the globe. ", The study results "seem to provide support to what we currently understand—that while the neutralizing antibody response is still developing post-vaccination and has not yet reached peak, there is still a risk of infection.". As the spring semester ends, the number of individuals living on campus as well as interactions in classrooms will drop. A variant first identified in New York in November accounted for nearly half of the cases diagnosed in the city by April 13. Scientists also tested the Novavax vaccine. Even so, Stern noted that while the study wasn't able to pinpoint precisely how much lower the vaccine's efficacy was against the B.1.351 variant, she pointed out that "even if the [B.1.351] variant does break through the vaccine's protection, it has not spread widely through the population. Even a less effective vaccine will keep you from becoming severely sick. But clearly, as we already knew, the vaccines are 100%. Janies: Coronaviruses, like all viruses, mutate randomly. Variants are determined by their genetic sequences. For example, CDC Director Rochelle Walensky last week said the B.1.1.7 variant, which was first identified in the United Kingdom, is now the United States' dominant coronavirus strain, The Hill reports. Former FDA comm. We help leaders and future leaders in the health care industry work smarter and faster by providing provocative insights, actionable strategies, and practical tools to support execution. The Moderna vaccine being administered in the Bronx last week. Similarly, a small study of Pfizer/BioNTech's vaccine found it was up to 100% effective at preventing even mild cases from the B.1.351 variant. Faculty and staff members can submit news, event information or story/video ideas for consideration via the online form or email insideuncc@uncc.edu. Martins: We recommend aiming for the campus to be fully vaccinated. However, Abdool Karim expressed more concern about the efficacy of AstraZeneca's vaccine, which has not been authorized in the United States, against certain variants. ", Separately, Richard Lessells, an infectious disease expert focusing on the B.1.351 variant, said he doesn't believe the results of this study should "worry us unduly. For example, one study of the vaccine developed by Novavax—which has not been authorized for use in the United States—found that, although it's about 89% effective at preventing mild Covid-19 from the original strain of the coronavirus, that efficacy drops to about 50% against B.1.351. According to NPR's "Goats and Soda," these experiments suggest it takes about eight times as many of the antibodies produced by the Moderna vaccine to neutralize the B.1.351 variant as to neutralize the original version of the virus. Is that safe? Public health becomes concerned about a SARS-CoV-2 variant when it affects COVID-19 transmission, severity, testing, treatment, or vaccine effectiveness. The more people who are vaccinated, the less the virus can spread and replicate. How effective are Covid-19 vaccines against variants? Widespread vaccination is our best bet — as a campus community and as a society — to get and stay ahead of COVID-19 and its variants. If we see a dramatic change in the number of residence halls indicating COVID and that the virus is spreading across campus, that may require us to make some adjustments. But if you think about variants as being random, which means they can be unpredictable, a variant might enable the virus to spread more efficiently or enable it to evade vaccine antibodies or cause a higher fatality rate. We do not know how long the vaccine will provide immunity, so if it’s discovered that a booster is needed to combat variants, we know the technology exists to produce it quickly. COVID vaccines tested on real-world variants in Israel. It has also shown to works against the variants too but […] "This means that the [B.1.351] variant is able, to some extent, to break through the vaccine's protection," Stern said. Now, they are involved in the sequencing of positive campus COVID-19 tests to monitor the presence of virus variants. The vaccine can do more than just create antibodies against COVID-19.
