With this approval, roughly 28 million more kids will become eligible for the coronavirus vaccine across the US. It comes at a pivotal time as schools have now reopened globally and the Delta variant is affecting more kids than ever. 

While kids’ risk of severe illness from COVID is still low, there have been over 500 pediatric deaths related to COVID-19. Over 40 deaths have also occurred due to a rare but serious coronavirus-linked condition called multi-system inflammatory syndrome (MIS-C), according to the CDC.

While some parents are planning to get their kids vaccinated, others are planning to wait it out before scheduling those shots.

Here’s everything you need to know about COVID Pfizer vaccination for children under 12 in Singapore. 


13 Facts About Covid Pfizer Vaccination Of Children Under 12, In Singapore And Other Countries


1. Efficacy of the vaccine

Pfizer’s clinical trial which started in March included 4,500 children ages 5 to 11 years. Almost two-thirds received a lower dose COVID vaccine and others received a placebo. This is to compare the outcomes for efficacy and side effects.  

It was found that the vaccine was 100% effective at protecting kids from any severe illness from coronavirus. The levels of antibody produced by kids in this age group were comparable to the immune response seen in kids 12 and over and adults.

Elizabeth Lloyd, M.D., a pediatric infectious diseases expert at the University of Michigan Health C.S. Mott Children’s Hospital, said that the vaccine produced a strong immune response in young kids and found that in multiple scenarios, the benefits of the vaccine outweighed the risks for this age group.


2. Side effects

Younger kids also experienced minor side effects.

For instance, more than two-third had pain and soreness at the injection site and two-fifths faced fatigue and nearly a third reported headaches. 

These side effects turned worse after the second dose, but it usually lasted just a couple of days. Lloyd explained that there were four serious adverse events that occurred during the trial, but further probe revealed that none of them were in any way related to the vaccine. 

Out of the 3,000 children who received the vaccine, there were only three cases of the COVID-19, but none of them led to any severe illness. 


3. Risk of Myocarditis

Myocarditis is a kind of inflammation in and around the heart and is an extremely rare side effect of the vaccine. It has predominantly affected men who are under the age of 30 and about 1 in 20,000 kids aged 12-17 years.

The good news is that none of the kids in the Pfizer trial between the ages of 5 and 11 years experienced myocarditis.

However, since it’s so rare, experts will continue to monitor it as a large number of kids receive the vaccine. Experts say that younger kids have an even lower risk of developing any rare side effects because they’re receiving a lower dose of the vaccine and are less likely to get myocarditis due to their developing immune systems.

For those who are 12 and above and have experienced myocarditis after the second dose of the vaccine, their symptoms are usually mild and short-lived, such as shortness of breath and chest pain. They resolve after a couple of days.


4. Dose of the Covid Pfizer vaccine

Kids who fall in the age group of 5-11 years will receive about a third of the dose as compared to those 12 and older – 10 micrograms compared to the 30 micrograms adults and teens receive. The smaller doses will be distributed with smaller needles and it will be easier for paediatricians and pharmacists to administer the vaccine to younger kids.

Experts say that current studies are on to see if a lower dose may eventually be appropriate for adults as well. 

Children aged 5-11 years will receive two doses of the vaccine three weeks apart. They will be considered fully vaccinated two weeks after they are given their second jab.

5. Where can kids get their jabs?

Once your kids are officially eligible, they will be able to get a COVID-19 vaccine from their paediatrician, at retail pharmacies, hospitals, health clinics, or even school-based sites depending on the location.

Unlike the vaccine rollout for adults, where the priority was on high-risk groups, all kids ages 5 to 11 will be eligible to get the dose. 


6. Younger kids should take both doses

Several studies conducted in adults show that the COVID-19 vaccine doesn’t offer the same protection after just one shot.

According to studies, just one dose of the Pfizer vaccine was only 30% effective against the Delta variant specifically.

Llyod mentions that both doses are necessary to get immunity and therefore, full vaccination for all ages is recommended.


7. Kids with underlying medical conditions shouldn’t skip their doses

The Pfizer trial for ages 5-11 years didn’t exclude kids suffering from allergies, asthma or any other comorbidities, like obesity, congenital heart disease, among others.

Doctors don’t recommend skipping vaccination because of any underlying medical condition. 

Jesse Hansen, M.D., a pediatric cardiologist says that vaccination is all the more important for kids who are immunocompromised in any way. 


8. When parents should consult doctors

There are some kids who are getting specific medications that may impact their immune response and make the vaccine less effective.

These families need to have conversations with their care teams as they plan to get their kids vaccinated. 

Kids who are preparing for surgery should also consult their doctors on the best timing to get the vaccine. Experts recommend that kids with a history of any severe allergic reaction should consult with their provider. 


9. How long should kids who have had COVID-19 wait to get vaccinated?

Kids can get vaccinated as soon as they feel better and have no symptoms, and are also done with any required quarantine. 

Llyod says, “It’s beneficial for kids to get vaccinated after having coronavirus and I wouldn’t recommend waiting longer than a couple of months.”

He further explains that no harmful viral particles will be shed from those who got the COVID vaccine. So, parents need not worry as there are no live viruses used in the COVID-19 vaccine.


10. How to prepare kids before their doses?

Some kids may be scared of needles, so as parents you can use child-friendly language to talk to them and explain why getting a shot is important not only for them but also for people around them. 

Similarly, you can also use various distractions like a video on the iPad or mobile phone. Assure them that the needle prick will just be like a poke and that you will be there with them all throughout the process.

11. Should kids still mask up after getting both their doses?

The recommendations may vary depending on how prevalent the virus is in the community. At present, both the American Academy of Pediatrics and CDC recommend kids to mask in schools and indoors.

In Singapore, children aged six and above are legally required to wear masks. Similarly, many kindergartens and pre-schools also strongly encourage the same practice for younger kids. 


12.  Do healthy kids need to get their vaccine?

Even though children are at low risk of severe illness or death from COVID-19, but unfortunately, there are some who do get hospitalised and their condition might turn fatal.

According to the federal data, ever since the start of the pandemic, over 1.9 million children aged 5-11 years have been infected, and there have been 94 deaths. 

There are some kids who are also experiencing other issues due to MIS-C and long-haul symptoms. Parents, therefore, need to remember that while their child’s risk of complications is low, vaccination is a simple way to protect children from COVID risks and also at the same time prevent the development of new variants. 


13. Status of Moderna and Johnson & Johnson’s vaccines for children under 12

Moderna’s vaccine for kids 6-11 are expected to be next in line to be reviewed by the FDA for emergency authorisation. The company had announced that its COVID-19 vaccine is also safe and effective and that it plans to submit data soon.

On the other hand, Johnson & Johnson’s clinical trials for kids as young as 12 are expected to start this fall.

Data from the other two age cohorts from the Pfizer trial – (children ages 2-5) and (children 6 months to 2 years of age) – are expected in the fourth quarter of this year.
