A new, highly transmissible coalition subvariable has been found in California — with the recent shift in the Trump administration threatening to make vaccines harder to obtain, and for many Americans, some health experts warn that the summer wave is more risky.

Secretary of Health and Human Services Robert F. Kennedy Jr.

Dr. Marty Makary, a Food and Drug Administration Commissioner, also said the agency will no longer approve COVID-19 COVID-19 vaccines for healthy people under the age of 65 each year.

“We simply don’t know if a healthy 52-year-old woman with normal BMI has received Covid-19 three times and having previously received six doses of the Covid-19 vaccine will benefit from the seventh dose,” Makary and another FDA official, Dr. Vinay Prasad, wrote in the New England Journal of Medicine this month. “This policy will force much-needed evidence to emerge.”

But, some experts say the requirement for a wider test could delay vaccine reception in many people, because those efforts may even be complete until the end of the upcoming winter flu and spin season.

"Pregnant women, infants and young children have a higher risk of hospitalization, and the safety of the Covid vaccine has been widely proven," Dr. Sean O'Leary, chairman of the American Society of Pediatric Diseases Committee, said in a statement.

Overall, access to the updated vaccine provides additional protection for children and adults to prevent shared-related emergency rooms and emergency care visits, the Centers for Disease Control and Prevention said.

According to some experts, recent federal changes could also prompt private and government insurers to stop shootings that have paid for the majority of the population, including babies and children.

Experts say Americans may end up paying the full cost of the vaccine without the advice of federal officials. For example, the out-of-pocket cost for the CVS’s shared vaccine is $198.99.

Although the emergency phase of the pandemic has passed, authorities noted that Kuved remains a public health issue. UC San Francisco UC San Francisco UC San Francisco UC Chin-hong said a relatively new subvariable has spread in Europe and Asia, especially in Hong Kong, Taiwan, other countries, Japan, etc. ”

The sub-variable NB.1.8.1 was first recorded in January and has since been found in California, including Los Angeles County and the San Francisco Bay Area. The World Health Organization designated it as a “variant under monitoring” last week.

NB.1.8.1 has grown exponentially worldwide in recent weeks. Data show that the OMICRON subvariable accounts for 10.7% of the virus samples analyzed globally. This is a sharp increase in the magnitude of 2.5% of the global sample compared to the week ending April 6.

"Although the number is still small, it's a significant increase," WHO said, adding that "in some countries with NB.1.8.1, cases and hospitalizations are increasing at the same time."

NB.1.8.1 is not common enough in the United States to be publicly tracked by the CDC. Another strain LP.8.1 is estimated to account for 73% of coronavirus specimens nationwide during the two-week period to two weeks on Saturday.

The data suggest that NB.1.8.1 won’t cause more serious illness, “but at least from what we’ve seen around the world and from laboratory experiments, it’s more transmissible,” said Dr. Yvonne Maldonado, an infectious disease expert at Stanford University.

In Taiwan, a senior health official told reporters that the epidemic caused by NB.1.8.1 "is continuing to rise rapidly, with continued increase in serious and fatal cases", which prompted a shortage of VOVID test kits, according to the Central News Agency. Health officials say one factor in Taiwan’s surge is the lack of large waves in the winter and predicts that the island’s current spike may not peak again in four to six weeks.

The prevalence of NB.1.8.1 has an increasing prevalence in each of each of the three regions, which still consistently share genetic analysis of the same sample-Western Pacific (including East Asia, parts of Southeast Asia and Australia); Europe; and the Americas.

According to the county Department of Public Health, the rate at which Covid tests in Los Angeles County have recovered positively has risen slightly over the past few weeks, although the overall positive rate remains low, at 3.5%. The levels of coronavirus found in wastewater in the county have increased by 6% in the past three weeks, but are also relatively low, about one-eighth of last summer.

Despite California's experience of a mild winter (the first season of the Coovid era), it was the strongest summer peak in years.

Many experts and officials are touting the available co-vaccine vaccines, both in avoiding infections and reducing the severity of symptoms. But otherwise healthy people need to roll up their sleeves has been a debate issue.

Kennedy in a video message Tuesday - a well-known vaccine skeptic - said he "can't be happier to announce that as of now, common vaccines for healthy children and healthy pregnant women have been removed from the CDC's recommended immunization program."

Experts say they don't remember a period of political appointments that circumvented the good process of developing vaccine recommendations, which often involves the recommendations of the scientists' team of scientists' FDA and the CDC.

“It’s a little chilling,” Chin-hong said. “This is inconsistent with the system we learn to trust and follow.”

In a statement to The Times, the Los Angeles County Department of Public Health urged Kennedy to listen to experts in the field, including the Centers for Disease Control and Prevention’s Immunization Measures Advisory Committee, which is scheduled to meet next month, “before reducing the chances of access to any vaccine.”

As of Thursday, the CDC still made a long-term vaccine recommendation on its website: Everyone over 6 months should get the latest Covid-19-19 vaccine, officially known as the 2024-25 edition, which was launched in September. The CDC also recommends that older adults, 65 years old, receive a second dose of vaccine after the first six months.

The California Department of Public Health said in a statement that it supports the widespread recommendations for the Covid vaccine and that federal dialogue will continue through this dynamic.”

"Keeping up to date with COVID-19 vaccinations can reduce the risk of the disease, especially in more severe cases, resulting in hospitalization or death," the department added.

The Washington Post reported Wednesday that the CDC didn’t know Kennedy’s instructions until it issued the Centers’ instructions, and officials have been “scrambling to find out what it means.”

Experts who spoke with the New York Times warned that if the ordinance becomes formal, the actual effect on affected groups could be more expensive.

"If the CDC does not recommend a vaccine, there is no need for insurers to cover the costs," the Los Angeles County Department of Public Health said in a statement.

As a result, the vaccine may be less accessible to healthier people who still want them — perhaps because they live or work with older people or other high-risk people, have had a serious illness before, or they want to protect themselves from the latest secondary variables.

The county said if the FDA deducts permission to renew COVID vaccination for younger, healthier adults, the organization “will not be received unless their provider chooses to 'close the tag',” the county said.

When asked if healthy pregnant women and healthy children can still get vaccinated at their pharmacies, Walgreens said its team “completely complies with applicable laws.” CVS said its location “follows federal guidance on vaccine management and is monitoring any changes in the government regarding vaccine eligibility.”

Kaiser Permanente Southern California said it has been aware of the potential changes, but noted that no new formal guidance has been issued. As a result, Kaiser continues to follow existing guidance that advises everyone on the lens.

As of Wednesday, “pregnant women and healthy children can vaccinate Covid-19,” according to existing recommendations from the advisory group and the CDC.

Chin-hong noted that in the past year, there have been 150 pediatric deaths from the United States from Covid-19. That's the same number of 231 pediatric flu deaths recorded this season, with federal health officials recommending that everyone over six months get an annual flu shot.

"Most people agree that children should target their children as flu vaccines," Chin-hong said.

"Most countries in the world stop recommending this vaccine to children's vaccines," Makary said in a video released this week.

However, Maldonado said the United States does not use other countries' standards to determine vaccine recommendations. Maldonado said, for example, the United States recommends that other types of vaccines be lower than the Covid than people want to get.

The effects of the recommendations also vary by country. For example, Canada recommends an updated Covid vaccine for older people and others who meet certain criteria, such as pregnant or medical workers. However, the country's universal health care system still allows for the newer Covid vaccine for every older person.

Although overall children are at a lower risk of illness overall, six-month-old children “have the same complication risk as the country’s population over 65 years old,” said Maldonado of Stanford University, who is also the CDC’s Advisory Committee on Immunization Practice.

According to the Centers for Disease Control and Prevention (CDC), the highest rates of hospitalization associated with age between 6 months and 4 years of age are eligible for vaccination.

"So will the kids be the highest risk group? No, they are not. But do you want to protect your kids from diseases that might put them in the hospital and take them to the ventilator? Yes, I want to say I want to make a choice for myself. Why not allow parents to make a choice?" Maldonado said.

The CDC says co-vaccination during pregnancy produces antibodies that can help protect babies. Research also shows that breastfeeding mothers have protective antibodies in milk, which can help protect babies.

Dr. Fiona Havers, a medical epidemiologist at the CDC, said in a recent public meeting that since October, an estimated 260,000 to 430,000 hospitalizations are attributed to Covid, which creates a “tremendous burden on the health care system”. During the same period, there were also estimated 30,000 to 50,000 covid-19 deaths.

“This is the main cause of morbidity and mortality, especially among older people, but it does affect others, especially those younger.”

She said Covid is a major cause of hospitalization for children even among other healthy children.

“If there is a summer wave this year, we will see it among children who are hospitalized at the same time,” she said.
