Pfizer says COVID-19 vaccine more than 90% effective in kids

Published

 on

Kid-size doses of Pfizer’s COVID-19 vaccine appear safe and nearly 91% effective at preventing symptomatic infections in 5- to 11-year-olds, according to study details released Friday as the U.S. considers opening vaccinations to that age group.

The shots could begin in early November — with the first children in line fully protected by Christmas — if regulators give the go-ahead.

Details of Pfizer’s study were posted online. The Food and Drug Administration was expected to post its independent review of the company’s safety and effectiveness data later in the day.

Advisers to the FDA will publicly debate the evidence next week. If the agency ultimately authorizes the shots, the Centers for Disease Control and Prevention will make the final decision on who should receive them.

Full-strength Pfizer shots already are authorized for anyone 12 or older, but pediatricians and many parents are anxiously awaiting protection for younger children to stem rising infections from the extra-contagious delta variant and help keep kids in school.

More than 25,000 pediatricians and primary care providers already have signed up to get the shots into little arms.

The Biden administration has purchased enough kid-size doses — in special orange-capped vials to distinguish them from adult vaccine — for the nation’s roughly 28 million 5- to 11-year-olds. If the vaccine is cleared, millions of doses will be promptly shipped around the country, along with kid-size needles.

A Pfizer study tracked 2,268 kids in that age group who got two shots three weeks apart of either a placebo or the low-dose vaccine. Each dose was one-third the amount given to teens and adults.

Researchers calculated the low-dose vaccine was nearly 91% effective, based on 16 COVID-19 cases in youngsters given dummy shots versus three cases among vaccinated children. There were no severe illnesses reported among any of the youngsters, but the vaccinated ones had much milder symptoms than their unvaccinated counterparts.

In addition, young children given the low-dose shots developed coronavirus-fighting antibody levels just as strong as teens and young adults who got regular-strength vaccinations.

That’s important information considering that hospitalizations of mostly unvaccinated children reached record levels last month.

The CDC reported earlier this week that even as the delta mutant surged between June and September, Pfizer vaccinations were 93% effective at preventing hospitalizations among 12- to 18-year-olds.

Pfizer’s study of younger kids found the low-dose shots proved safe, with similar or fewer temporary side effects such as sore arms, fever or achiness that teens experience.

The study isn’t large enough to detect any extremely rare side effects, such as the heart inflammation that occasionally occurs after the second dose, mostly in young men.

While children run a lower risk of severe illness or death than older people, COVID-19 has killed more than 630 Americans 18 and under, according to the CDC. Nearly 6.2 million children have been infected with the coronavirus, more than 1.1 million in the last six weeks as the delta mutant surged, the American Academy of Pediatrics says.

Moderna also is studying its COVID-19 shots in elementary school-age youngsters. Pfizer and Moderna are studying even younger children as well, down to 6-month-olds. Results are expected later in the year.

Why BioTech is important

Published

Biotechnology has many advantages including helping improve food quality, quantity, and processing, as well as also has having functions in manufacturing, where simple cells and proteins can be manipulated to produce chemicals.

The source of biotechnology comes from the fact that technology aims to create tools to empower humans, aiming to change humans themselves to better fit them to the world. Also, Biotechnology is the application of advances made in the biological sciences, especially involving the science of genetics and its application.

Its implications in health and medicine gives the importance of Biotechnology, by having scientists being able through genetic engineering, which is the controlled alteration of genetic material, to create new medicines, including interferon for cancer patients, synthetic human growth hormone and synthetic insulin, among others.

As such, the significance of biotechnology is shown by having scientists use the tools of biotechnology to manipulate cells with increasing control, from precision editing of DNA to synthesizing entire genomes from their basic chemical building blocks. These cells could go on to become bomb-sniffing plants, miracle cancer drugs, or ‘de-extinct’ wooly mammoths, and biotechnology may be a crucial ally in the fight against climate change according to the Future of Life Institute.

“The impact of biotech is huge on people’s lives, having the majority of the food we eat coming from engineered plants, which are modified – either via modern technology or by more traditional artificial selection – to grow without pesticides, to require fewer nutrients, or to withstand the rapidly changing climate,” the institute added.

“Manufacturers have substituted petroleum-based ingredients with biomaterials in many consumer goods, such as plastics, cosmetics, and fuels. Your laundry detergent? It almost certainly contains biotechnology. So do nearly all of your cotton clothes,” it noted.

Even so, biotech is present in our detailed lives, helping us in every way possible, such as the assistance to prenatal screening and home pregnancy test, in addition to immunizations and antibiotics, which improved life expectancy. Also, biotechnology is the main reason for many drugs that heal diseases such as cancer and heart disease.

On the other hand, biotechnology has its own disadvantages and consequences for the fact that microbes are tiny and difficult to detect, however the dangers are enormous. Further, engineered cells could divide on their own and spread in the wild, with the possibility of far-reaching consequences.

The unintended consequences of benign research or the purposeful manipulation of biology to cause harm, are factors that prove that biotechnology can be harmful.

iSTAR gains European approval for implant for glaucoma surgery

Published

 on

While glaucoma is the leading cause of irreversible blindness affecting around 100 million people worldwide, iSTAR Medical, a Belgium-based medtech company pioneering novel minimally-invasive implants for glaucoma surgery (MIGS), announced Wednesday, that its breakthrough MIGS device, MINIject™, has been approved in Europe for open-angle glaucoma patients.

As such, MINIject enables more patients to be effectively treated with MIGS because of its powerful and sustained performance combined with an excellent safety profile.

In addition, it represents the most promising and fastest-growing glaucoma therapy, due to its enhanced safety profile compared to traditional surgery. Studies by iSTAR Medical across four trials in over 150 patients, show that MINIject demonstrates a balance of powerful and sustained intra-ocular pressure (IOP) reduction with a positive safety profile.

“With today’s European approval, MINIject becomes the only commercially available MIGS device targeting the supraciliary space as a natural outflow pathway for IOP reduction,” Michel Vanbrabant, CEO of iSTAR Medical, said.

“This is a major milestone for iSTAR Medical and our mission to bring truly next-generation MIGS devices to the glaucoma community,” he noted. “I want to thank our team, our investors, and our medical partners for their continued belief in a safer and better way to manage glaucoma by targeting the supraciliary space, with an implant powered by our proprietary STAR material,” the CEO added.

Professor Dr. Burkhard Dick, head of the Department of Ophthalmology at University Eye Hospital Bochum, Germany, and one of the MINIject STAR-II trial investigators, treated the first patient with MINIject after European approval.

 Moreover, MINIject is being investigated in iSTAR Medical’s pivotal STAR-V study, which was approved by the United States Food and Drug Administration (FDA) in July 2021, the results of which will be instrumental to gain commercial access for MINIject in the U.S. market.

EU regulator authorizes Pfizer’s COVID vaccine for kids 5-11

Published

The European Union’s drug regulator on Thursday authorized Pfizer’s coronavirus vaccine for use on children from 5 to 11 years old, clearing the way for shots to be administered to millions of elementary school pupils amid a new wave of infections sweeping across the continent.

It is the first time the European Medicines Agency has cleared a COVID-19 vaccine for use in young children.

The agency said it “recommended granting an extension of indication for the COVID-19 vaccine Comirnaty to include use in children aged 5 to 11.”

After evaluating a study of the vaccine in more than 2,000 children, the EMA estimated that the vaccine was about 90% effective in preventing symptomatic COVID-19 in young children and said the most common side effects were pain at the injection site, headaches, muscle pain and chills. The agency said the two-dose regimen should be given to children three weeks apart.

At least one country facing spiking infections didn’t wait for the EMA approval. Authorities in the Austrian capital, Vienna, already have begun vaccinating the 5 to 11 age group. Europe is currently at the epicenter of the pandemic and the World Health Organization has warned the continent could see deaths top 2 million by the spring unless urgent measures are taken.

The EMA green light for the vaccine developed by Pfizer and German company BioNTech has to be rubber-stamped by the EU’s executive branch, the European Commission, before health authorities in member states can begin administering shots.

Earlier this week, Germany’s health minister Jens Spahn said shipping of vaccines for younger children in the EU would begin on Dec. 20.

The United States signed off on Pfizer’s kids-sized shots earlier this month, followed by other countries including Canada.

Pfizer tested a dose that is a third of the amount given to adults for elementary school-age children. Even with the smaller shot, children who are 5 to 11 years old developed coronavirus-fighting antibody levels just as strong as teenagers and young adults getting the regular-strength shots, Dr. Bill Gruber, a Pfizer senior vice president, told The Associated Press in September.

But the studies done on Pfizer’s vaccine in children haven’t been big enough to detect any rare side effects from the second dose, like the chest and heart inflammation that has been seen in mostly male older teens and young adults.

American officials noted that COVID-19 has caused more deaths in children in the 5 to 11 age group than some other diseases, such as chickenpox, did before children were routinely vaccinated.

Earlier this month, the EMA said it began evaluating the use of Moderna Inc.’s COVID-19 vaccine for children ages 6 to 11; it estimated that a decision would be made within two months.

Although children mostly only get mild symptoms of COVID-19, some public health experts believe immunizing them should be a priority to reduce the virus’ continued spread, which could theoretically lead to the emergence of a dangerous new variant.

Researchers disagree on how much kids have influenced the course of the pandemic. Early research suggested they didn’t contribute much to viral spread. But some experts say children played a significant role this year spreading contagious variants such as alpha and delta.

In a statement this week, WHO said that because children and teens tend to have milder COVID-19 disease than adults, “it is less urgent to vaccinate them than older people, those with chronic health conditions and health workers.”

It has appealed to rich countries to stop immunizing children and asked them to donate their doses immediately to poor countries who have yet to give a first vaccine dose to their health workers and vulnerable populations.

Still, WHO acknowledged that there are benefits to vaccinating children and adolescents that go beyond the immediate health benefits.

“Vaccination that decreases COVID transmission in this age group may reduce transmission from children and adolescents to older adults, and may help reduce the need for mitigation measures in schools,” WHO said.
