The Food and Drug Administration’s independent vaccine advisory committee voted unanimously Thursday to allow all COVID-19 vaccines in the U. S. to be able to do so. U. S. foods use the same wording as updated two-strain boosters.
This would make vaccination less confusing for patients and physical care workers, said the Advisory Committee on Vaccines and Related Biologics (VRBPAC).
The committee voted 21-0 to order vaccine makers Moderna, Pfizer-BioNTech and Novavax to update the number one series of their vaccines, the initial doses other people get, to adapt updated bivalent booster doses that target the original SARS-CoV. -2 strain and a new Omicron strain.
The original strain is no longer in circulation, however, Omicron-like variants of the target through the updated bivalent boosters continue to spread.
Before this update goes into effect, the FDA will have to approve the committee’s recommendation, which the company will likely do.
Dr. James Cutrell, an associate professor of medicine in the Division of Infectious Diseases and Geographic Medicine at UT Southwestern Medical Center in Dallas, said having a type of COVID-19 vaccine will make it less difficult just for the public, but also for fitness care. Workers.
“This will simplify things for the other people administering the vaccine,” he said, “and result in less vaccine waste because you don’t need to inventory two versions. “
Also, if the FDA makes the decision to update the vaccine in the future, it will only have one vaccine to update, said Cutrell, who is not a member of the FDA’s advisory committee.
Some discussions at Thursday’s assembly warned that the existing complexity of having two types of COVID-19 vaccines and vaccination schedules for teams of other ages may also contribute to low vaccination rates in the United States.
“Part of the discussion about why we haven’t had a major recall is that the procedure is complicated,” said Dr. John Sellick, Jr. , a professor of infectious diseases at Jacobs School of Medicine.
Currently, about 70 percent of Americans have won the full number one series, according to the Centers for Disease Control and Prevention (CDC).
However, only 16. 5% of other eligible people received an updated bivalent reminder. And among high-risk seniors, only four in 10 got an updated bivalent booster.
Serial primary vaccination rates among young children are even lower, according to data presented at Thursday’s assembly: 3 percent in children aged 6 months to 2 years and 5 percent in children aged 2 to 4 years.
Hospitalizations are also higher in children younger than 2 over the past year, compared with other pediatric age groups, the committee learned.
“The maximum information point I saw all day was this incredibly low immunization policy between 6 months and 2 years and also between 2 and 4 years,” said Dr. Brown. Amanda Cohn, director of CDC’s Division of Births. Childhood defects and disorders.
“We want to do much, much better,” he said, adding that simplifying the procedure by having a COVID-19 vaccine for singles would get more young people vaccinated.
Cutrell, however, still believes that the main advantages of this update will be to simplify the process for healthcare workers.
“I don’t think switching to one type of vaccine has a significant effect on the motivation of other people who don’t need to be vaccinated,” he said.
While FDA documents released before the assembly emphasized the desirability of a COVID-19 vaccine for single people, the panel also heard information emerging that bivalent vaccines are effective.
In November 2022, other people over the age of five who received an updated bivalent booster were 2. 4 times less likely to die from COVID-19 than those who were vaccinated but did not receive the bivalent booster.
Moderna also presented new insights from a randomized clinical trial in the UK on bivalent BA. 1 recall. People who received the bivalent booster had a lower risk of COVID-19 than those who received the booster with the original vaccine.
The bivalent vaccine used in the UK targets the BA. 1 Omicron variant, while the US vaccines target the BA. 4 and BA. 5 Omicron variants. All of these variants are similar to the Omicron variants circulating lately.
Sellick, who is a member of the FDA’s advisory committee, said the benefits of COVID-19 boosters are subsidized by science.
“When you look at it from the matrix of antibody grades . . . Strengthening in normal periods is good,” he said.
In addition, “we now have clinical knowledge that other people who have the number one series and are driven continue to have smart coverage rather than poor outcomes: going to the hospital or going to the morgue, the poor end outcome,” he said.
Panel members also supported FDA scientists’ proposal to move to an annual dose of the COVID-19 vaccine for most Americans.
Under the plan, the vaccine would be adapted to recently circulating strains of SARS-CoV-2, the coronavirus that causes COVID-19.
Most adults, teens and younger older children who have already been vaccinated would receive a single dose a year, according to the FDA’s plans.
High-risk seniors, those with compromised immunity, and young people who have not yet been vaccinated would receive additional doses.
Cutrell said the FDA and CDC will know which other people will get the maximum benefits from annual COVID-19 vaccines.
Based on the knowledge presented at the meeting, he said he will most likely come with older people, other immunocompromised people and, in all likelihood, very young children.
In the UK, autumn COVID-19 boosters are only for others over 50, others at higher risk of COVID-19, pregnant women, and frontline social care and fitness workers.
The FDA’s proposed plan calls for the VRBPAC to meet annually in May or June to discuss whether COVID-19 vaccine formulations want to be updated to better accommodate variants circulating at the time.
This timeline would allow mRNA vaccine brands to redesign vaccines and release new doses for deployment in the fall.
However, this timing would not work for the protein-based Novavax vaccine. The company said at the meeting that it would take six months to update its vaccine.
“This is a scenario in which Pfizer and Moderna have transparent merit over Novavax because of the nature of mRNA vaccines, which can be updated and manufactured faster,” Cutrell said.
Sellick said the shorter time needed to update mRNA vaccines may also result in greater adjustment with circulating variants.
However, as new variants of the coronavirus emerge during the year, there is no guarantee that the variants targeted by the updated vaccine will adjust to what circulates after deployment.
“It’s going to be a challenge,” Sellick said.
The proposed annual update would be for the procedure used to update seasonal influenza vaccines.
Every year, certain flu strains dominate and spread around the world. Flu vaccines are designed to target strains that may be circulating.
The coronavirus, however, does not follow the same pattern. The variants made the impression in other countries, some causing waves in many countries, while other variants remained more local.
In addition, the coronavirus has not shown the same seasonality as the flu virus, which begins to spread through the northern hemisphere every year in the fall.
Still, Cutrell said if there’s going to be an annual COVID-19 vaccine, it makes sense to roll it out alongside the flu vaccine.
“This will help protect others during the winter, when hospitals are closer to capacity due to influenza and other respiratory viruses,” he said.
