ACIP Backs Moderna's COVID Shot for Kids 6-17 Years – Medpage Today

Published

 on


The CDC’s Advisory Committee on Immunization Practices (ACIP) voted unanimously on Thursday to recommend that children ages 6-17 years receive Moderna’s COVID-19 vaccine.

With a 15-0 vote, ACIP endorsed a two-dose primary series of the mRNA vaccine for kids ages 6-11 years (50 mcg per dose) and adolescents ages 12-17 (100 mcg per dose). The recommendation now awaits approval from CDC Director Rochelle Walensky, MD, MPH.

The recommendation was largely expected, and followed FDA’s emergency use authorization last week. Until then, only Pfizer/BioNTech’s mRNA vaccine had been authorized and recommended for these age groups.

At Thursday’s meeting, ACIP members considered safety and efficacy data on Moderna’s vaccine, which was primarily studied during periods where the ancestral SARS-CoV-2 and Delta strains were predominant, in teens and the younger kids, respectively. In both groups, the vaccine was effective against severe disease and hospitalization.

“We know that the benefits outweigh the risks for mRNA COVID-19 vaccine in all ages,” said Sara Oliver, MD, of the CDC’s National Center for Immunization and Respiratory Diseases, during the meeting. “Receipt of this primary series continues to be the safest way to prevent serious COVID-19.”

Oliver emphasized that serious outcomes with COVID-19 do not spare kids. The Omicron wave was accompanied by a surge in hospitalizations among children, and she pointed to 189 COVID-related deaths in kids 5-11 years and 443 in kids 12-17 throughout the course of the pandemic.

Several ACIP members raised questions about the intervals between the first and second dose of the Moderna vaccine, as such an approach may reduce the risk of myocarditis associated with the vaccine. Some evidence suggests the Moderna vaccine carries a higher risk of myocarditis or pericarditis than Pfizer’s vaccine, though CDC experts cautioned that these findings are not consistent in all U.S. monitoring systems.

Among close to 55 million doses of Pfizer’s vaccine administered to individuals ages 5-17 years, the rare adverse event has been observed in at least 635 children, according to the CDC. Risk is typically higher among children ages 12-17, in boys, and after the second dose. Among kids age 5-11, there were no signals detected.

In a presentation on clinical considerations, Elisha Hall, PhD, of the CDC’s National Center for Immunization and Respiratory Diseases, said that although the current recommendation is for a 4-week gap between the first and second doses, the CDC will likely be recommending an 8-week interval for adolescent males. (The CDC also recommends shorter dose intervals for children who are immunocompromised.)

Some of the ACIP members expressed confusion about the product labels on Moderna’s vaccines in each age group. The product authorized for kids 6-11 will have the same color cap as the vaccine for children ages 6 months to 5 years, but a different color border to distinguish the higher concentration. For the product authorized for kids ages 12-17, it will have the same label as the adult vaccine, as it is the same dose.

“I am … concerned about vaccine administration errors,” said Matthew Daley, MD, chair of ACIP’s working group. Others echoed concerns about administration blunders, encouraging more resources for providers and further clarification on labeling from the manufacturer.

Safety and efficacy data for Moderna’s vaccine in this younger population came from two ongoing phase II/III clinical trials (study mRNA-1273-P203 for adolescents ages 12-17 and study mRNA-1273-P204 for kids ages 6-11 years). The studies included nearly 8,000 kids in total.

Among participants ages 12-17, vaccine efficacy was 93.3% (95% CI 47.9-99.9) during a time when the ancestral and Alpha strains were predominant. Among the younger group, vaccine efficacy was 76.8% (95% CI -37.3 to 96.6) during a period when Delta was most prevalent.

The committee agreed on the data that COVID-19 vaccines protect children against severe disease. Many children in this age group, however, remain unvaccinated. Approximately 30% of teens and 65% of younger kids have yet to receive a vaccine, according to Oliver.

“We can predict with future COVID-19 surges, the unvaccinated will continue to bear the burden of disease,” she said.

Canada to donate up to 200,000 vaccine doses to combat mpox outbreaks in Africa

Published

 on

 

The Canadian government says it will donate up to 200,000 vaccine doses to fight the mpox outbreak in Congo and other African countries.

It says the donated doses of Imvamune will come from Canada’s existing supply and will not affect the country’s preparedness for mpox cases in this country.

Minister of Health Mark Holland says the donation “will help to protect those in the most affected regions of Africa and will help prevent further spread of the virus.”

Dr. Madhukar Pai, Canada research chair in epidemiology and global health, says although the donation is welcome, it is a very small portion of the estimated 10 million vaccine doses needed to control the outbreak.

Vaccine donations from wealthier countries have only recently started arriving in Africa, almost a month after the World Health Organization declared the mpox outbreak a public health emergency of international concern.

A few days after the declaration in August, Global Affairs Canada announced a contribution of $1 million for mpox surveillance, diagnostic tools, research and community awareness in Africa.

On Thursday, the Africa Centres for Disease Control and Prevention said mpox is still on the rise and that testing rates are “insufficient” across the continent.

Jason Kindrachuk, Canada research chair in emerging viruses at the University of Manitoba, said donating vaccines, in addition to supporting surveillance and diagnostic tests, is “massively important.”

But Kindrachuk, who has worked on the ground in Congo during the epidemic, also said that the international response to the mpox outbreak is “better late than never (but) better never late.”

“It would have been fantastic for us globally to not be in this position by having provided doses a much, much longer time prior than when we are,” he said, noting that the outbreak of clade I mpox in Congo started in early 2023.

Clade II mpox, endemic in regions of West Africa, came to the world’s attention even earlier — in 2022 — as that strain of virus spread to other countries, including Canada.

Two doses are recommended for mpox vaccination, so the donation may only benefit 100,000 people, Pai said.

Pai questioned whether Canada is contributing enough, as the federal government hasn’t said what percentage of its mpox vaccine stockpile it is donating.

“Small donations are simply not going to help end this crisis. We need to show greater solidarity and support,” he said in an email.

“That is the biggest lesson from the COVID-19 pandemic — our collective safety is tied with that of other nations.”

How many Nova Scotians are on the doctor wait-list? Number hit 160,000 in June

Published

 on

 

HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.

The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.

Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.

“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”

The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.

A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.

Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.

“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.

Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.

The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.

“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

Newfoundland and Labrador monitoring rise in whooping cough cases: medical officer

Published

 on

 

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.

Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.

Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.

Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.

The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.

“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.

Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.

Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.

Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.

A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
