At the first meeting of the controversial new group of vaccine advisory groups with the U.S. Centers for Disease Control and Prevention, the committee announced a new plan to study established vaccine guidelines.
The Advisory Committee on Vaccination Practices will create a new workgroup to study the cumulative effects of childhood and adolescent vaccine schedules, the hepatitis B vaccine dose administered at birth, and the combination of measles, mumps and chicken pox vaccines.
It was the first time a new group of seven external CDC vaccine advisors have been convened since US Health and Human Services Secretary Robert F. Kennedy Jr. rejected a previous panel of 17 experts this month, claiming they had a conflict of interest. He appointed a new group of eight members two days later. They withdraw during the financial holdings screening, leaving seven people behind to review the country’s vaccine recommendations.
Public health experts were concerned about both the unprecedented layoffs of the previous committee and the background and status of some of the new advisors. Two served as expert witnesses to the vaccine in the trial, while others suggested that the Covid-19 vaccine contributed to the deaths of young people and should be removed from the market.
Kennedy, who led the anti-vaccine group’s child health defense before becoming HHS’s secretary, suggests that childhood vaccines are understudied. Pediatricians and infectious disease experts say that isn’t the case.
The American Academy of Pediatrics said Wednesday that it would no longer be participating in the ACIP meeting because “with the committee being fired, it is no longer a reliable process.”
“We don’t lend names or expertise to systems that are politicized at the expense of child health,” Dr. Sue Cresley said the organization has pledged to continue to publish vaccination schedules developed by experts developed by science that pediatricians and families across the country.
Kulldorff said the new workgroup on childhood and adolescent vaccine schedules will look at “interacting effects between different vaccines, cumulative amounts of vaccine components, and the relative timing of different vaccines.”
Dr. Paul Offit, a vaccine scientist at Children’s Hospital of Philadelphia and a member of the U.S. Food and Drug Administration’s external vaccine advisory board, said that every time a vaccine was added to the schedule, its interaction with other vaccines was reviewed.
“We need to prove that a vaccine does not interfere with the safety or immunogenic profile of existing vaccines, and vice versa,” he told CNN on Wednesday.
Offitt said the new committee’s plan is “a purely anti-vaccine agenda that will bring it back to life with public policy.”
The second new workgroup considers vaccines that have not been reviewed for more than seven years, Kulldorff said, including whether hepatitis B vaccines should be universally recommended for newborns.
“Unless the mother has hepatitis B, we can argue that it will delay the vaccine for this infection. This infection is predominantly spread through sexual activity and intravenous drug use,” Kulldorff said.
The CDC states that “universal HEPB vaccination of all infants beginning at birth provides important safeguards and prevents infection in babies born to mothers with unspecified (hepatitis B) positive prior to birth.”
“Scientific evidence provides overwhelming support for the safety of the hepatitis B vaccine,” the agency says.
“Hepatitis B can be handed over from a parent to a baby at birth — and if that happens, the outcome can be fatal. It’s unscientific and dangerous to ignore the success of US vaccination programs.
When universal birth volume recommendations were temporarily suspended in 1999, some confusion broke out, with about 10% of hospitals halting all birth volumes regardless of infant risk, Offit wrote in the Journal of New England Medicine in 2007.
The third new workgroup will consider vaccines for measles, mumps, rubella, chicken, or water cell, Kruldorf said, “The vaccine is important for combating measles at the first dose of 12 to 15 months.”
This vaccine can be used as a combination of all four or as two shots that protect against water cells that are given individually. A combination of four vaccins is given to children between the ages of 1 and 2 is a high-understandable risk of febrile attacks. Administering a water cell vaccine apart from the MMR vaccine avoids this increased risk, and the CDC notes that it is “very low for both options.”
Kulldorff said the committee could reevaluate the one-year-old vaccine recommendations and that the Working Group could consider the best timing of the vaccine and potential alternatives like those used in Japan.
The US has seen a decline in measles vaccination rates, with more than 1,200 cases reported this year since the US was eliminated in 2000. Everything was not vaccine-connected.
ACIP recommendations have historically been subject to a major shaking. They affect both vaccination insurance coverage and state insurance.
