Health experts say that even as more people are vaccinated and boosted, the corona virus is here to stay. And they warn that future variants will likely keep medical practitioners and researchers on their toes as they work to keep both infections and the severity of infections down.<\/p>\n

Their message to the public is, don\u2019t let your guard down.<\/p>\n

\u201cCOVID is going to be with us for the foreseeable future,\u201d said Dr. William Schaffner, professor of medicine in the Division of Infectious Diseases at Vanderbilt University School of Medicine. \u201cWe\u2019re struggling to figure out how we can keep this virus down and minimize its damage, and still at the same time enjoy a reasonably normal life.\u201d<\/p>\n

Schaffner was among a panel of speakers for a\u00a0July 29 media briefing<\/a>\u00a0organized by Ethnic Media Services on the latest Covid variant, and the mounting questions around the pandemic and vaccine efficacy.<\/p>\n

COVID 19 cases, deaths, and hospitalizations are once again on the rise in the US. More than two-thirds of Americans have tested positive for COVID, including President Joe Biden, who again tested positive for the second time in a case of Covid rebound. The BA5 subvariant of Omicron is now responsible for more than 78% of infections in the country, according to data from the Centers for Disease Control and Prevention (CDC).<\/p>\n

But public health experts say the figures could represent a severe undercount, with many people failing to report positive results from at-home tests.<\/p>\n

Shaffner stressed that updated vaccines will continue to be an essential part of the broader strategy. \u201cWe need more durable, long-term protection against a broader array of different variants, the ones we know and the ones we don\u2019t know yet,\u201d he said. \u201cWe would like vaccines that abort and prevent the actual infection at the surface of the mucous membranes, not just vaccines that protect against serious disease.\u201d<\/p>\n

Nasal vaccines, which can be administered via a spray or dropper, are gaining more attention among clinical researchers and could offer another route to increasing vaccination rates. The NovaVax vaccine, recently authorized by the Food and Drug Administration (FDA) was licensed for an initial two-dose series, but not yet for a booster.<\/p>\n

But Dr. Ben Neuman, professor of biology and chief virologist of the Global Health Research Complex at Texas A&M University, has his doubts.<\/p>\n

\u201cNovaVax vaccine is fine, but it\u2019s about two years too late,\u201d he said, adding the drug does not replicate the virus as effectively as other vaccines. \u201cNovaVax has this very delicate spike protein that is transported and protected very carefully; a little bit survives to go into your body\u2026 With the mRNA vaccine, you get perfect pristine spikes exactly the way nature intended.\u201d<\/p>\n

Neuman noted that to date there have been 15 mutations of the Omicron variant, including the newer BA.5 and BA2.75 subvariants, for which the current vaccines appear less effective.<\/p>\n

\u201cWe are still vaccinating against the 2019 virus and it is now late 2022,\u201d he said. \u201cWe have a problem.\u201d<\/p>\n

Nearly a third of Americans remain unvaccinated, while a majority of Covid-related deaths are occurring among people 65 and over, including those who have been vaccinated.<\/p>\n

Speakers stressed that masks continue to play a critical role in slowing the spread of the virus, particularly for those who are at high risk because of age or underlying conditions.<\/p>\n

Currently no state mandates mask wearing in public, though several states still require mask wearing in high risk settings, including hospitals and long-term care facilities.<\/p>\n

In April, a federal judge struck down the Biden administration\u2019s mask requirement for public transit, airlines and transportation hubs. The Justice Department is expected to appeal the ruling.<\/p>\n

Meanwhile, one-third of Americans have managed to avoid being infected by the virus altogether. According to Dr. Peter Chin-Hong, associate dean for Regional Campuses at the University of California, San Francisco, four factors help explain this trend.<\/p>\n

Some people may be genetically disposed to having higher resistance to the virus, said Chin-Hong, something doctors saw during the early years of the HIV\/AIDS crisis. These individuals\u00a0 could play a role in future research on therapeutics for Covid, Chin-Hong noted.<\/p>\n

Behavior could be another factor, \u201cas some people in the same household may be taking more precautions\u201d in terms of wearing a mask or having close contact with other people. The timing of vaccines also plays a role, as the risks of infection have fluctuated over time during the pandemic.<\/p>\n

Finally, says Chin-Hong, some people may have been infected and just did not realize it, either because they were asymptomatic or because they were never tested.<\/p>\n

Chin-Hong believes that wastewater inspections can help to clarify the picture around actual infection rates. Unlike relying on tests and self-reporting, wastewater can help researchers understand the extent to which the virus is spreading within a community.<\/p>\n

\u201cFor example in California, the level of wastewater virus is very similar to (reported Covid levels) in January, when more people were getting tested,\u201d explained Chin-Hong. Based on this data, current case rates would be far higher than the 130,000 daily infections now being reported.<\/p>\n

A summer surge of Respiratory Syncytial Virus (RSV), which can cause Covid-like symptoms, could also explain why a lot of people have received negative results on their home testing kits, said Shaffner.<\/p>\n

\u201cThe rapid tests are also less apt to give you a positive result in this BA5 era\u2026 that is why the CDC keeps focusing on hospitalizations, because they remind us that there is this important public health problem.\u201d<\/p>\n

Therapeutics such as PAXLOVID have proven to be effective in preventing more severe diseases, mostly among older adults. And there is a monoclonal antibody that can be given to some people who are resistant to PAXLOVID. But experts insist that vaccines remain the most essential tool to fight the virus.<\/p>\n

\u201cWe now we have too many deaths, like 430 a day,\u201d says Chin-Hong. \u201cWe have to manage (the virus) and we have the tools to do that right now,\u201d he concluded.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
