FDA, Pfizer delay authorization for COVID vaccine for kids under 5: What to know

The FDA will review data on all three doses of the vaccine for young kids, instead of starting with just two. The data should be available in early April.

For the most up-to-date news and information about the coronavirus pandemic, visit the WHO and CDC websites.

Parents of children under 5 will have to wait a little longer to get their kids vaccinated against COVID-19.

Pfizer and BioNTech announced Friday that the companies are extending their «rolling submission» process for the vaccine for kids 6 months through 4 years and are waiting for more data on all three doses before asking the US Food and Drug Administration to authorize the first two shots. Just two doses of the vaccine weren’t effective for the whole age group.

The FDA said on Friday that the agency is postponing its Feb. 15 committee meeting, which would’ve included a vote on whether to move forward with the first doses of the COVID-19 vaccine for young kids. The agency said that it will provide an updated time for a new meeting once the FDA receives additional data for the full vaccine.

«The extension allows the FDA time to receive updated data on the two- and three-dose regimen, conduct a thorough evaluation of it, and facilitate a robust, public discussion,» Pfizer and BioNTech said in the announcement. The companies expect to have three-dose protection data by early April, they said.

Last week, Pfizer and BioNTech submitted data to the FDA for authorization of their COVID-19 vaccine for children 6 months through 4 years old. While the vaccine for children under 5 is expected to be a three-dose vaccine series (it’s one-tenth the volume of Pfizer’s vaccine for people 12 and up), the FDA asked the companies to submit data on the first two doses as part of a «rolling submission» process.

In December, Pfizer announced that while two doses of the vaccine were effective in children ages 6 months to 2 years, two shots failed to promote a strong enough immune response in children ages 2 through 4 years. This prompted the company to start testing a three-dose version of the vaccine for children under 5.

Updated Sunday, the Centers for Disease Control and Prevention’s Pediatric COVID-19 Vaccination Operational Planning Guide indicates that the agency has 10 million vaccine doses ready for dispersal, and that state and local health officials could start receiving doses as early as Feb. 21. Without FDA authorization beforehand, this will be postponed.

Kids as young as 5 have been able to be vaccinated against COVID-19 since October 2021. The Kaiser Family Foundation reports that 28.1% of kids 5 to 11 have received at least one vaccine shot as of Jan. 18. Read on to learn everything you need to know about COVID-19 vaccines for kids under 5.

Also, learn about whether we’ll need a fourth booster shot, the latest on long COVID and the possibility of a vaccine that works against all COVID-19 variants.

Why did Pfizer and the FDA extend the authorization process?

At the FDA’s request, Pfizer and BioNTech started the submission process last week for authorization of the first two doses of the vaccine for kids 6 months through 4 years last week.

But in a statement Friday, the FDA said: «Based on the agency’s preliminary assessment, and to allow more time to evaluate additional data, we believe additional information regarding the ongoing evaluation of a third dose should be considered as part of our decision-making for potential authorization.»

The vaccine for children under 5 covers kids 6 months through 4 years. While two shots of the smaller-dose vaccine were effective in babies and toddlers 6 months to 2 years, receiving only two doses failed to promote a strong immune response in children 2 to 4 years. Studies on a third dose are ongoing, but expected to complete the series for kids under 5.

«Given that the study is advancing at a rapid pace, the companies will wait for the three-dose data as Pfizer and BioNTech continue to believe it may provide a higher level of protection in this age group,» the companies said Friday.

The extension of the rolling submission process for the vaccine for kids under 5 comes as a disappointment for many parents wanting to protect their younger children against COVID-19, but it’s more in line with earlier estimates from public health officials on when a COVID-19 vaccine might be available for the age group.

When can babies and children under 5 get the vaccine?

Once Pfizer and BioNTech submit additional information to the FDA, a committee of experts that gathers to discuss safety and effectiveness data and vote on whether or not the FDA should authorize a vaccine will meet. The agency will provide an update on timing for the meeting on the vaccine for kids under 5 once they receive more data, FDA Commissioner Dr. Janet Woodcock and Dr. Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research said in a statement Friday.

«This will give the agency time to consider the additional data, allowing for a transparent public discussion as part of our usual scientific and regulatory processes for COVID-19 vaccines,» the doctors said.

The advisory committee’s meetings are open to the public.

If the FDA does authorize Pfizer’s vaccine for children as young as 6 months old, the CDC typically goes through the same process: An outside panel of health experts will discuss the benefits and risks of recommending the vaccine to children under 5 years old. If they vote to recommend Pfizer’s vaccine for the younger age group, the CDC’s director will likely accept the panel’s decision and the small doses of Pfizer’s COVID-19 vaccine for kids will become available in pediatricians’ offices or other clinics.

Pfizer and BioNTech’s COVID-19 vaccine is not the only one being studied in kids under 5, however. Moderna said in January that it expects to report vaccine data on children 2 to 5 years in March. In a few countries outside the US, including Canada, Moderna’s vaccine has received regulatory authorizations for adolescents 12 and up.

How is Pfizer’s child vaccine for young kids different?

Pfizer and BioNTech’s vaccine for children 6 months through 4 years comes in two doses that are one-tenth the volume of the vaccine for people age 12 and up. A third 3-microgram dose is being researched right now is expected to complete the series.

The vaccine for kids 5 to 11 is one-third the dose given to everyone 12 and up, and it’s delivered in two doses. Pfizer’s vaccine for kids can also be stored for up to 10 weeks in a fridge, making it easier to administer, and the cap on the vial is orange instead of purple and gray to avoid mix-ups.

And if it helps to put your kids at ease, the needle used to administer the child’s dose of vaccine is also smaller.

Can my child get a COVID booster?

Children as young as 12 can now get a booster dose of Pfizer’s COVID-19 vaccine, given at least five months after their primary vaccination series.

Most kids younger than 12 can’t get a booster, although the CDC recommends a third dose of the Pfizer vaccine for children 5 and up who are immunocompromised. They’re eligible for a third shot 28 days after their second dose.

Where can my kid get a booster shot?

Since Pfizer’s COVID-19 vaccine is the lone vaccine approved for people under 18, it’s generally only available in doctor’s offices and public health clinics, not pharmacies and other mass vaccination sites.

Call your pediatrician or local health clinic for a recommendation on where to go. Parents may also text their ZIP code to 438829 or use this vaccine finder link to find a clinic near them that has the child vaccine available.

Do kids really need a COVID-19 vaccine?

According to a report from the American Academy of Pediatrics, children made up 25% of reported COVID-19 cases for the week ending Feb. 3. (The AAP says the definition of «child» varies by the states reporting.) While pediatric cases were lower than in January, child COVID-19 were «double the peak level of the delta surge in 2021,» the AAP reported.

While it’s true children are much less likely to get severely sick from the virus than adults, some children have died or been hospitalized with the virus. An infection, even a mild case, requires quarantining and potentially sending classmates out of the classroom and back to remote learning. And kids can experience dangerous complications from COVID-19, including long COVID and MIS-C.

There are also racial disparities in the severity of how sick children get from COVID-19: Kids ages 5 to 11 who are Black, Native American or Hispanic are three times more likely to be hospitalized with COVID-19 than white children, according to an FDA advisory panel presentation. Of that group, about 1 in 3 will require admission to an intensive care unit.

Are booster shots safe for children?

In a statement following its authorization of booster doses for kids 12 to 15, the FDA said it reviewed real-world data from more than 6,300 children in Israel, ages 12 to 15, who received a booster shot at least five months after their second dose of Pfizer.

No additional safety concerns were reported to date in those individuals, according to the FDA.

«These additional data enabled the FDA to reassess the benefits and risks of the use of a booster in the younger adolescent population in the setting of the current surge in COVID-19 cases,» the agency said. «The data shows there are no new safety concerns following a booster in this population.»

What are the side effects? Is the COVID vaccine safe for kids?

Vaccine side effects in kids ages 5 to 11 are mostly mild and similar to those adults may experience, according to the CDC, including soreness at the injection site, fever, muscle soreness, nausea and fatigue. In a Dec. 13 report from the agency, the CDC reviewed reports from safety monitoring systems on more than 8 million doses of Pfizer’s vaccine given to kids ages 5 to 11, confirming that children’s immune systems respond well to the vaccine with common mild side effects, and that serious adverse events are rarely reported.

Inflammation of the heart muscle, known as myocarditis, and of the muscle’s outer lining, called pericarditis, are rare and typically mild side effects linked to the Moderna and Pfizer vaccines, mostly in adolescent males and young men ages 12 to 29. (Myocarditis can also occur after infection with COVID-19.)

In one study, the CDC said that 54 recipients out of a million males ages 12 to 17 experienced myocarditis following the second dose of Pfizer-BioNTech’s Comirnaty vaccine. In contrast, kids ages 5 to 11 who catch COVID-19 have a higher risk of multisystem inflammatory syndrome, or MIS-C, a potentially serious complication involving inflammation of the heart, lungs, kidneys, brain, skin, eyes or other organs.

«The bottom line is that getting COVID is much riskier to the heart than anything in this vaccine, no matter what age or sex you are,» Dr. Matthew Oster, a pediatric cardiologist at Children’s Healthcare of Atlanta, told the CDC in November as reported by ABC News.

Do I need to give consent for my young child to get vaccinated?

Yes, parents generally need to consent to their children receiving medical care, including Pfizer’s COVID-19 vaccine. This is especially true for younger children.

However, depending on which state you live in, there may be a legal precedent for teens and other kids to request the vaccine without parental permission: Tennessee’s vaccine director, Michelle Fiscus, was fired in August allegedly in part for sending out a memo detailing Tennessee’s «mature minor doctrine,» which explains how minors may seek medical care without the consent of their parents.

If my child has a serious health condition, can they get a third shot?

The CDC recommended a third dose for children as young as 5 who are «moderately to severely» immunocompromised, 28 days after their second shot. This guidance for immunocompromised children (including kids who’ve had an organ transplant or are taking medications that suppress the immune system) is in line with guidance for adults whose bodies don’t mount a good immune response to the COVID-19 vaccines.

My child has allergies. Can they get the vaccine?

Yes, though you might be asked to stick around the waiting room so health care providers can monitor them for (extremely rare) allergic reactions that can occur after any vaccination.

«If the child has a history of anaphylaxis or other severe allergies, then the observation time after the injection may be 30 minutes instead of 15,» said Dr. Anne Liu, an infectious disease specialist with Stanford Hospital and Clinics and the Lucile Packard Children’s Hospital. Children who have been prescribed an EpiPen for any reason should bring it to their vaccine appointment, Liu added.

As with adults, children with an allergy to an ingredient in Pfizer’s COVID-19 shouldn’t take it. You can find a list of ingredients in Pfizer’s vaccine for kids ages 5 to 11 on the FDA’s fact sheet.

Can my child get the COVID-19 shot at the same time as other vaccines?

According to the CDC, your child may get other vaccines when they go in for their COVID shot without waiting 14 days between appointments. Flu shots can be given to children ages 6 months and older.

Apple, I’m (Sky) Blue About Your iPhone 17 Air Color

Commentary: The rumored new hue of the iPhone 17 Air is more sky blah than sky blue.

I can’t help but feel blue about the latest rumor that Apple’s forthcoming iPhone 17 Air will take flight in a subtle, light-hued color called sky blue.

Sky blue isn’t a new color for Apple. It’s the featured shade of the current M4 MacBook Air, a shimmer of cerulean so subtle as to almost be missed. It’s silver left too close to an aquarium; silver that secretly likes to think it’s blue but doesn’t want everyone else to notice.

Do Apple employees get to go outside and see a real blue sky? It’s actually vivid, you can check for yourself. Perhaps the muted sky blue color reflects a Bay Area late winter/early spring frequent layer of clouds like we typically see here in Seattle.

«Who cares?» you might find yourself saying. «Everyone gets a case anyway.» I hear you and everyone else who’s told me that. But design-focused Apple is as obsessive about colors as they are about making their devices thinner. And I wonder if their heads are in the clouds about which hues adorn their pro products.

Making the case for a caseless color iPhone

I’m more invested in this conversation than most — I’m one of those freaks who doesn’t wrap my phone in a case. I find cases bulky and superfluous, and I like to be able to see Apple’s design work. Also, true story, I’ve broken my iPhone screen only twice: First when it was in a «bumper» that Apple sent free in response to the iPhone 4 you’re-holding-it-wrong Antennagate fiasco, and second when trying to take long exposure starry night photos using what I didn’t realize was a broken tripod mount. My one-week-old iPhone 13 Pro slipped sideways and landed screen-first on a pointy rock. A case wouldn’t have saved it.

My current model is an iPhone 16 Pro in black titanium — which I know seems like avoiding color entirely — but previously I’ve gone for colors like blue titanium and deep purple. I wanted to like deep purple the most but it came across as, in the words of Patrick Holland in his iPhone 14 Pro review, «a drab shade of gray or like Grimace purple,» depending on the light.

Pros can be bold, too

Maybe the issue is too many soft blues. Since the iPhone Pro age began with the iPhone 11 Pro, we’ve seen variations like blue titanium (iPhone 15 Pro), sierra blue (iPhone 13 Pro) and pacific blue (iPhone 12 Pro).

Pacific blue is the boldest of the bunch, if by bold you mean dark enough to discern from silver, but it’s also close enough to that year’s graphite color that seeing blue depends on the surrounding lighting. By comparison, the blue (just «blue») color of the iPhone 12 was unmistakably bright blue.

In fact, the non-Pro lines have embraced vibrant colors. It’s as if Apple is equating «pro» with «sophisticated,» as in «A real pro would never brandish something this garish.» I see this in the camera world all the time: If it’s not all-black, it’s not a «serious» camera.

And yet I know lots of pros who are not sophisticated — proudly so. People choose colors to express themselves, so forcing that idea of professionalism through color feels needlessly restrictive. A bright pink iPhone 16 might make you smile every time you pick it up but then frown because it doesn’t have a telephoto camera.

Color is also important because it can sway a purchase decision. «I would buy a sky blue iPhone yesterday,» my colleague Gael Cooper texted after the first rumor popped online. When each new generation of iPhones arrive, less technically different than the one before, a color you fall in love with can push you into trading in your perfectly-capable model for a new one.

And lest you think Apple should just stick with black and white for its professional phones: Do you mean black, jet black, space black, midnight black, black titanium, graphite or space gray? At least the lighter end of the spectrum has stuck to just white, white titanium and silver over the years.

Apple never got ahead by being beige

I’m sure Apple has reams of studies and customer feedback that support which colors make it to production each year. Like I said, Apple’s designers are obsessive (in a good way). And I must remind myself that a sky blue iPhone 17 Air is a rumored color on a rumored product so all the usual caveats apply.

But we’re talking about Apple here. The scrappy startup that spent more than any other company on business cards at the time because each one included the old six-color Apple logo. The company that not only shaped the first iMac like a tipped-over gumdrop, that not only made the case partially see-through but then made that cover brilliant Bondi blue.

Embrace the iPhone colors, Apple.

If that makes you nervous, don’t worry: Most people will put a case on it anyway.

Astronomers Say There’s an Increased Possibility of Life on This Distant Planet

Using the James Webb Space Telescope, astronomers are working to confirm potential evidence of life on a distant exoplanet dubbed K2-18b.

Astronomers are nearing a statistically significant finding that could confirm the potential signs of life detected on the distant exoplanet K2-18b are no accident.

The team of astronomers, led by the University of Cambridge, used data from the James Webb Space Telescope (which has only been in use since the end of 2021) to detect chemical traces of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), which they say can only be produced by life such as phytoplankton in the sea. 

According to the university, «the results are the strongest evidence yet that life may exist on a planet outside our solar system.»

The findings were published this week in the Astrophysical Journal Letters and point to the possibility of an ocean on this planet’s surface, which scientists have been hoping to discover for years. In the abstract for the paper, the team says, «The possibility of hycean worlds, with planet-wide oceans and H2-rich atmospheres, significantly expands and accelerates the search for habitable environments elsewhere.»

Not everyone agrees, however, that what the team found proves there’s life on the exoplanet.

Science writer and OpenMind Magazine founder Corey S. Powell posted about the findings on Bluesky, writing, «The potential discovery of alien life is so enticing that it drags even reputable outlets into running naive or outright misleading stories.» He added, «Here we go again with planet K2-18b.Um….there’s strong evidence of non-biological sources of the molecule DMS.»

K2-18b is 124 light-years away and much larger than Earth (more than eight times our mass), but smaller than Neptune. The search for signs of even basic life on a planet like this increases the chances that there are more planets like Earth that may be inhabitable, with temperatures and atmospheres that could sustain human-like lifeforms. The team behind the paper hopes that more study with the James Webb Space Telescope will help confirm their initial findings.

More research to do on finding life on K2-18b

The exoplanet K2-18b is not the only place where scientists are exploring the possibility of life, and this research is still an early step in the process, said Christopher Glein, a geochemist, planetary researcher and lead scientist at San Antonio’s Southwest Research Institute. Excitement over the significance of the research, he said, should be tempered.

«We need to be careful here,» Glein said. «It appears that there is something in the data that can’t be explained, and DMS/DMDS can provide an explanation. But this detection is stretching the limits of JWST’s capabilities.»

Glein added, «Further work is needed to test whether these molecules are actually present. We also need complementary research assessing the abiotic background on K2-18b and similar planets. That is, the chemistry that can occur in the absence of life in this potentially exotic environment. We might be seeing evidence of some cool chemistry rather than life.»

The TRAPPIST-1 planets, he said, are being researched as potentially habitable, as is LHS 1140b, which he said «is another astrobiologically significant exoplanet, which might be a massive ocean world.»

As for K2-18b, Glein said many more tests need to be performed before there’s consensus on life existing on it.

«Finding evidence of life is like prosecuting a case in the courtroom,» Glein said. «Multiple independent lines of evidence are needed to convince the jury, in this case the worldwide scientific community.» He added, «If this finding holds up, then that’s Step 1.»
