The U.S. Centers for Disease Control and Prevention (CDC) on Sept. 12 recommended that nearly all Americans receive one of the new COVID-19 vaccines.
People who have not received a COVID-19 vaccine in the past two months should receive one of the new shots, according to the agency.
“CDC is now recommending updated COVID-19 vaccination for everyone 6 months and older to better protect you and your loved ones,” CDC Director Dr. Mandy Cohen said in a statement.
The new vaccines are expected to be available later this week.
They target the XBB.1.5 virus variant. That variant has been displaced by variants such as EG.5, according to CDC data.
The recommendation came after the Advisory Committee on Immunization Practices, a set of experts who advise the CDC, advised the CDC to recommend the shots for people aged 6 months or older, regardless of underlying health, prior vaccination, or previous COVID-19.
Discussion
Most advisers voted to advise the CDC recommend the shots.“It’s clear that vaccination is going to prevent serious illness and death across all age groups,” said Dr. Beth Bell, one of the advisers.
“I recognize that long COVID is a big deal and the risk goes down with COVID vaccine,” said Dr. Katherine Poehling, another adviser.
The vote was split 13–1, with one adviser indicating he didn’t feel a universal recommendation was backed by evidence.
“I certainly think that 65 and older should because of the data presented, and certainly other high-risk groups should, but I think the rest should be ’may,'” Dr. Pablo Sanchez, the adviser, said.
The CDC can say people should or may receive a vaccine or group certain populations into shared clinical decision-making, which explicitly leaves the decision to a person and their doctor.
Data on Vaccines
Moderna before the advisers’ vote presented data from a trial of 101 people, 50 of whom received the XBB.1.5 shot.Within seven days of vaccination, adverse reactions were similar to or lower than earlier Moderna doses, according to Moderna’s presentation.
Moderna officials also said that neutralizing antibodies went up after receipt of a vaccine across newer variants, such as EG.5.1, though the increases were lower for people with prior infection.
No efficacy estimates were presented.
The vaccine “is anticipated to be effective against current SARS-CoV-2 variants,” Dr. Frances Priddy, a Moderna official, said. SARS-CoV-2 is a name for the virus that causes COVID-19.
Testing in mice found an increase in neutralizing antibodies when comparing the new vaccine to older shots, according to Pfizer’s presentation.
Approximately 400 people 12 and older also received one of the new shots, but results from that trial were not presented.
Novavax also presented data on its new vaccine, which has not yet been cleared. Novavax says the vaccine increased neutralizing antibodies in monkeys. It presented no clinical data.
Novavax’s vaccine can be folded into the new recommendations if ultimately cleared, without the panel meeting again.
Vaccines for many others will be covered through Medicare, Medicaid, and insurance, according to the CDC.
Just 17 percent of the U.S. population has received one of the shots that became available in the fall of 2022, according to CDC data. Some seven out of 10 people have received a primary series.
Surveys have shown that reasons for not receiving a vaccine include concern over side effects and the belief that they do not need a vaccine.
Lack of Data on Children
None of the data provided evidence supporting vaccination in children, advisers acknowledged.“The data on children is not there, and for that I think this discussion needs to be had,” Dr. Sanchez said.
Still, some advisers said it was safe to assume the vaccines will work in kids.
“We don’t have a lot of data in children, but ... it’s likely there will be a benefit,” Dr. Oliver Brooks, one of the advisers, said.
Dr. Matthew Daley, another adviser, noted there is data on children for earlier versions of the vaccines.
He claimed that the vaccines can prevent deaths, which was not shown during the meeting.
Dr. Robert Malone, who helped invent the technology the Pfizer and Moderna vaccines use and is not on the panel, told EpochTV’s “Crossroads” before the vote that he is opposed to recommending the new COVID-19 vaccines.
“We have a lack of data to support this decision,” he said, adding later, “These products have no substantial benefit, and they have a significant risk.”
