\nBy Madeline Holcombe | CNN<\/strong><\/h3>\nSome states are making great strides in vaccinating their residents against Covid-19, but the ones that are not may soon be contending with a more transmissible variant, experts say.<\/p>\n
About 45.2% of the US population is fully vaccinated against Covid-19, CDC data showed, and in 16 states and Washington, DC, that proportion is up to more than half, and 16 have reached President Joe Biden\u2019s goal to vaccinate 70% of adults with at least one dose.<\/p>\n
But some states \u2014 such as Alabama, Arkansas, Louisiana, Mississippi, Tennessee and Wyoming \u2014 have fully vaccinated less than 35% of residents.<\/p>\n
More than 500 days and 600,000 deaths since the first person in the United States was reported to have died from Covid-19, experts have upheld vaccines as the key to reopening the country safely and containing the variants, many of which are more transmissible.<\/p>\n
The Delta variant, which is believed to be more transmissible and cause more severe disease, could cause an upsurge in infections, but the levels will vary depending on the rates of vaccination in each area, said Scott Gottlieb, former commissioner of the US Food and Drug Administration, on CBS\u2019s \u201cFace the Nation.\u201d<\/p>\n
\u201cWhen we look across the United States, we see wide variance in terms of vaccination rates,\u201d said Gottlieb, who compared places like Vermont and Connecticut, which have rates of over 80%, with others that are struggling to get to 50%.<\/p>\n
New research suggests less vaccinated areas are at risk. Scientists at Helix analyzed nearly 20,000 Covid-19 tests collected since April and found the Delta variant is quickly rising in counties with fewer vaccinated residents.<\/p>\n
Models for Delta\u2019s spread show the fall could see a peak of around 20% of the infections the US recorded in January, but the distribution of those predicted surges is not even across all areas, Gottlieb explained.<\/p>\n
\u201cConnecticut, for example where I am, shows no upsurge of infection, but Mississippi, Alabama, Arkansas, Missouri, show very substantial upsurges of infection. That\u2019s based entirely on how much population wide immunity you have based on vaccination,\u201d he said.<\/p>\n
In Springfield, Missouri, the low rate of vaccinations combined with the Delta variant has led to a six-fold increase in hospitalizations at CoxHealth, a health care system there, according to its CEO, Steve Edwards.<\/p>\n
Over the past four and a half weeks, the number of patients has risen from around 14 to 83, Edwards told CNN on Monday, adding that the patients are younger and have more severe disease than previously \u2014 and almost all are unvaccinated.<\/p>\n
The Delta variant made up about 10% of cases that were tested three or four weeks ago, he said. \u201cAs of last week, it appeared to be 90%.\u201d<\/p>\n
\u201cI think it is the Delta variant, and there is a lot of kindling with low vaccination rates, so it\u2019s spreading very rapidly.\u201d<\/p>\n
This influx has put new pressures on his staff, Edwards said, compared to previous outbreaks.<\/p>\n
\u201cIt is harder to know that you\u2019re risking your well-being for someone that chose not to vaccinate, that then puts you and them at risk.\u201d<\/p>\n
Turning focus to communities<\/strong><\/p>\nMore than 300 million vaccine doses have been administered in the US, a feat which has enabled students to go back to the classroom, businesses to reopen and friends and families to gather once again.<\/p>\n
But there\u2019s still a long way to go, CNN medical analyst Dr. Leana Wen warned over the weekend.<\/p>\n
\u201cWe certainly have to acknowledge that we have come a long way, and we\u2019re out of the worst of it. We\u2019re not going to see the massive surges that we saw over the holidays,\u201d said Wen, who is the former health commissioner for Baltimore.<\/p>\n
\u201cThe problem, though, is that we should really be looking at the numbers for each community instead of looking at the US as a whole because while the US as a whole is doing so much better, and there are pockets of the country that have very high vaccination rates, we also have pockets of the country that are actually undergoing massive surges right now where their hospitals are getting full again,\u201d Wen said.<\/p>\n
The US has been focused on getting vaccines out and into mass vaccination sites, but now it is the time to rethink the way doses are made accessible, Gottlieb told CBS.<\/p>\n
\u201cNow we need to think about trying to push out the vaccine into community sites where people could get it delivered to them through a trusted intermediary, that\u2019s going to mean doctors\u2019 offices, schools, places of employment,\u201d Gottlieb said. \u201cWe need to think about a different vaccine delivery strategy to get the people who are still reluctant or who still face challenges getting into those access sites.\u201d<\/p>\n
While health experts agree full vaccination offers protection against some variants of Covid-19, Wen added that it\u2019s unknown whether a variant resistant to vaccines will emerge. \u201cWe just don\u2019t know. If it\u2019s anything that we\u2019ve learned during Covid-19, it\u2019s how much we need to be humble in the face of this virus,\u201d she said.<\/p>\n
She noted that it\u2019s \u201ccertain\u201d new variants will develop, which could make vaccines slightly ineffective, but not entirely.<\/p>\n
\u201cThis is another reason why those who are unvaccinated should be vaccinated as soon as possible,\u201d Wen said.<\/p>\n
Variants of concern on the rise<\/strong><\/p>\nThe Delta variant, along with the Gamma or P.1 variant, have been deemed variants of concern by the Centers for Disease Control and Prevention \u2014 meaning their danger comes from their ability to transmit more easily or cause more severe disease.<\/p>\n
The Gamma variant, first identified in Brazil, has been detected in every US state where the CDC has variant information.<\/p>\n
Vaccination has been shown as the best way for the US to get ahead of the variants. A recent study by Public Health England found that two doses of a coronavirus vaccine are \u201chighly effective against hospitalization\u201d caused by the Delta variant. The study found the Pfizer\/BioNTech vaccine is 96% effective against hospitalization after two doses.<\/p>\n
Surgeon General Vivek Murthy previously told CNN there isn\u2019t enough data to indicate the effectiveness of Johnson & Johnson\u2019s one-dose vaccine in regard to the Delta variant, but it has shown it can help prevent hospitalizations and deaths when people are infected with other strains.<\/p>\n
\u201cThe key is get vaccinated, get both doses,\u201d Murthy said.<\/p>\n
Edwards, the CEO of CoxHealth, told CNN last week that the Delta variant is unlike others.<\/p>\n
\u201cWe can\u2019t tell why one patient is doing poorly and one is doing well. There\u2019s just something different about how this variant is affecting the immune system of our patients,\u201d Edwards said.<\/p>\n
