In the wake of the CDC‘s approval of Pfizer and Moderna‘s Covid-19 vaccine for babies as young as six months, at least one expert has questioned the move.

Dr. Sarah Long, an infectious diseases expert at the Drexel University College of Medicine, told the New York Times: ‘We should just assume that we don’t have efficacy data.’ 

That comes off the back of Pfizer’s own reporting that said their statements of 80% effectiveness in children under five was based on the responses of just three children.

Those children were part of a group of ten but seven were given a placebo.

And there are also concerns about the Moderna shot, which is only between 37 per cent and 51 per cent effective, depending on the age of the child receiving it.

Dr. Sally Long of Drexel University has stated that ‘We should just assume that we don’t have efficacy data’ about vaccines for those under five years old.

According to the Times report, the CDC noted in their meeting this past Friday on whether or not to approve the vaccines that Pfizer’s metric was unreliable. 

Dr. Long said that despite this she was ‘comfortable enough’ in approving the vaccines based on other data. 

Both Moderna and Pfizer’s vaccines were shown to have a success rate of around 95% in adults. However in Moderna’s case, that number is just 37% in children aged two through five. 

The shot is effective in 51 per cent of children aged between six months and 23 months.  

Earlier in June 2022, FDA advisors met to discuss new vaccines to deal with new mutations of Covid-19. Public health authorities have expressed a worry that a new mutation in the latter part of the year, could undermine vaccines, reports CNBC.

According to the CDC, the Pfizer vaccine requires three shots for those between six months and five years old. Moderna requires tw.

According to the CDC, the Pfizer vaccine requires three shots for those between six months and five years old. Moderna requires two. 

For Moderna, it takes around 42 days after the first dose to achieve maximum protection in a child. In Pfizer’s case, it takes 90 days. Although, Pfizer’s protection may last for longer, reports the Times. 

While Dr. William Towner, who performed vaccine trials for both Moderna and Pfizer, told the Times he felt most parents who choose to vaccinate would opt for Moderna as it has one less shot. 

However Dr. Towner noted: ‘It’s really going to be impossible to say on is better than the other.’ 

Around 2.5 million doses of the Pfizer vaccine and 1.3 million of Moderna have been ordered. 

According to the census bureau, there are around 20 million children aged between six months and five years old in the United States. 

In November, Pfizer’s vaccine was approved for five to 11 year olds but less than 30% of that age group has received two doses.

A survey from the Kaiser Family Foundation Vaccine Monitor in April found that just 18% of parents were planning to vaccinate the children if and when they were approved for under fives.

CDC Director Rochelle Walensky has signed off on Covid-19 vaccines for babies as young as six months old – and couldn’t keep the smile from her face as she announced the news on June 18. 

Walensky’s approval came hours after a panel of advisors to the U.S. Centers for Disease Control and Prevention on Saturday voted unanimously 12-0 to recommend COVID-19 vaccines for children as young as six months

This means that a nationwide role out is likely to begin next week, even though the most recent statistics show just 442 children aged between 0 and four have died of COVID in the US since the pandemic began two years ago. 

The U.S. Food and Drug Administration on Friday authorized Moderna Inc’s shot for children aged six months to fiveyears, and Pfizer-BioNTech’s vaccine for children aged six months to four years. Pfizer’s vaccine is already authorized for children over the age of five.

Following the approval, Walensky posted a clip on Twitter where she said: ‘Nearly 20 million children are now able to get vaccinated against Covid-19. I know many parents with very young children have been anticipating this day.’

Walensky continued: ‘We now know, based on rigorous scientific review, that the vaccines available here in the United States can be used can be used safely and effectively in children under five. Vaccinating children is a critical opportunity to protect them against hospitalization and death from Covid-19.’

For children ages one through four years old, Covid-19 is the fifth leading cause of death. 

The same data says that hospitalizations of that age group spiked during December 2021 at the height of the Omicron wave. 

But for the vast majority of children infected by COVID, the symptoms are exceptionally mild.

Conversely, young children are at risk of a rare but potentially serious – and even deadly – inflammation of the heart linked to COVID vaccines called myocarditis. 

Millions of American children have already been infected with COVID and recovered, further complicating the issue, as an infection is believed to leave people with at least a few months of immunity.   

That has left many parents weighing up whether to vaccinate their child, although experts have urged them to do so.

The shot will also be welcomed by parents of under-fives with underlying conditions that leave the vulnerable to potentially-serious side effects from COVID.

And the virus itself is also found to have caused a rare but serious inflammatory disorder dubbed MIS-C, meaning some parents may opt to get their children the shot to try and protect them from that condition. 

In a statement, Walensky said: ‘Together, with science leading the charge, we have taken another important step forward in our nation’s fight against COVID-19.’

The director added: ‘We know millions of parents and caregivers are eager to get their young children vaccinated, and with today’s decision, they can.’ 

‘I encourage parents and caregivers with questions to talk to their doctor, nurse, or local pharmacist to learn more about the benefits of vaccinations and the importance of protecting their children by getting them vaccinated.’

According to the CDC’s own statistics, 442 children ages four and under have died in the US from Covid-19

For children ages 1 through 4 years old, Covid-19 is the fifth leading cause of death

President Joe Biden has said that the national rollout for children will begin after the holiday weekend

one of the doctors on the CDC panel, said following the vote. ‘Here is an opportunity to prevent a known risk.’

President Joe Biden’s administration plans to roll out the vaccines to the under five age groups on Tuesday following the Juneteenth holiday weekend. 

‘We will begin shipping millions of vaccine doses for kids to thousands of locations parents know and trust – including pediatricians’ offices, children’s hospitals, and pharmacies,’ Biden said in a statement on Friday.

‘As doses are delivered, parents will be able to start scheduling vaccinations for their youngest kids as early as next week, with appointments ramping up over the coming days and weeks.’

Biden’s Covid tsar, Dr. Ashish Jha, has said that there will be 10 million doses available for babies and children

Biden’s Covid tsar, Dr. Ashish Jha, has said that there will be ten million doses available for babies and children.

 Dr. Matthew Daley, a senior clinician investigator at Kaiser Permanente’s Institute of Health Research, said on Friday that those over the age of five who are not vaccinated were ten times more likely for die from Covid-19. 

Dr. Daley did not say what the fatality rates were for unvaccinated children under the age of five. 

While many parents in the United States are eager to vaccinate their children, it is unclear how strong demand will be for the shots. 

The Pfizer-BioNTech vaccine was authorized for children aged five to 11 in October, but only about 29% of that group is so far fully vaccinated, federal data shows.

CVS Health Corp plans to provide vaccines to children aged 18 months and older while Rite Aid Corp and Walmart Inc plan to offer these shots for kids who are at least three years old. Infants are traditionally vaccinated at a doctor’s office.

Public health officials have been pushing for childhood vaccinations ahead of the new school year as they hope shots for the age group will help prevent hospitalizations and deaths if COVID-19 cases rise again.

The CDC advisers will meet again next week to consider whether to back use of the Moderna vaccine for children and adolescents aged six-17. 

There has been some concern about the rate of rare cases of heart inflammation in teenage boys and young men from the Moderna vaccine, and the advisers are expected to consider that data.

Moderna requires two doses.

How long is it in between doses?

The first and second doses are given within three weeks of each other. 

How long does it take to reach maximum protection? 

Maximum protection is achieved within 42 days.

Why does Moderna only have two doses?

Moderna has a higher dosage  of the vaccine which is why it works faster
