The COVID-19 vaccine is here for children ages 5-11 years old! This is their shot to get back to a more normal life after months of isolation and masking. The best we can do as parents is make an informed decision based on the scientific information available. Learn more about the Pfizer-BioNTech mRNA vaccine approved for this age group and get answers about common myths and misinformation about COVID-19 vaccines in general.
As of Nov. 2, 2021, the Pfizer-BioNTech vaccine has been endorsed by the U.S. Food and Drug Administration (FDA) and approved for emergency use in this age group with a recommendation made by the Centers for Disease Control and Prevention Advisory Committee on Immunization Practices. The vaccine is given in 2 doses, 21 days apart. Two weeks after the second dose, your child is considered fully vaccinated. Each dose is 10 micrograms (less than the 30 micrograms for patients 12 years and older). The lower dose is safe and works very well in younger children because their immune systems are stronger.
Studies are still ongoing for children under age 5 as well as for the use of the Moderna and Johnson & Johnson/Janssen vaccines in children and teenagers.
The Pfizer vaccine contains the mRNA for the spike protein, lipids (fats) to help the mRNA get into the cells and a salt and sugar buffer to keep the vaccine stable until it is ready to be given. There are no preservatives, latex, eggs or metals in the vials. There are no tissues, gelatin or any materials from animals.
The messenger RNA (mRNA) vaccines work by teaching the body to recognize the COVID-19 virus in the future. Of note, unlike many other vaccines, mRNA vaccines do not contain any parts of inactivated viruses or bacteria.
Here’s how it works! The COVID-19 virus looks like a ball covered in spikes. The mRNA vaccine teaches your body to make proteins that look just like the spikes on COVID-19 but are not actually the virus. None of the other parts of the virus are made. After getting the vaccine, the immune system (system in the body that fights diseases and infections) recognizes the spikes should not be there. It produces antibodies (disease-fighting proteins) that help the body get rid of them. These antibodies remember what to do if and when your body is exposed to the virus in the future. After the mRNA coaches your body how to make the spike protein, it is broken down and leaves the cells in just a few hours.
In the Pfizer vaccine trial for 5–11-year-olds, 1,518 children received the vaccine and 750 received a placebo (an injection that had no vaccine). Three children in the vaccine group and 16 children in the placebo group got COVID-19 infection. The trial had a vaccine efficacy rate of 90.7% (it worked to prevent symptomatic COVID-19 in more than 90 of every 100 participants). The trial has since been expanded to 4,500 children to allow for even more safety monitoring.
The most common side effect was pain at the injection site (71%). Similar to what we have seen in older children and adults, reactions occurred more frequently after the 2nd dose, including:
Side effect | Children with the side effect after dose 1 | Children with the side effect after dose 2 |
---|---|---|
Fatigue | 33% | 39% |
Headache | 22% | 28% |
Chills | 5% | 13% |
Fever | 9% | 13% |
Aches | 9% | 12% |
Lymphadenopathy and rash | 0.9% | 0.9% |
There were NO reports of myocarditis, blood clots, anaphylaxis or death.
Most side effects go away within 1-2 days. The side effects are a signal that the immune system is learning how to protect your child’s body against the virus. If your child doesn’t get side effects, it does not mean the vaccine did not work.
Peter Marks, MD, PhDNo parent should have to lose their child to a vaccine-preventable illness if we have a vaccine that can be deployed that is safe and effective.
Paul Offit, MDWe are not going to get control of this pandemic until we vaccinate the unvaccinated.
Yes, vaccination is still recommended. Research has not shown how long you are protected from getting COVID-19 again after you have recovered. Recent studies are showing evidence that people get better protection by being fully vaccinated compared with having had COVID-19 infection. If your child received antibody-based treatments for COVID-19, talk with your doctor about when to get the vaccine.
Myocarditis has been reported as a very rare side effect (about 1 in 20,000 people) after the 2nd dose of mRNA vaccines, mostly in males ages 16-29 years old. It is very important to put this information in context and weigh the risks and benefits. The risk of getting myocarditis after COVID-19 infection is much higher than the risk of getting myocarditis after vaccination. There were no cases of myocarditis in children ages 5-11 years old in the Pfizer vaccine study. In older children and young adults who developed myocarditis after vaccination, cases were mild and resolved quickly. Compare this to about 75% of children with COVID-19 related MIS-C (multisystem inflammatory syndrome in children) who developed myocarditis, many cases of which were severe with long-term effects.
There is no scientific research that COVID-19 vaccines affect or reduce fertility. In phase 3 trials of mRNA vaccines, an equal number of women in the placebo group (no vaccine) and vaccine group became pregnant. As described above, the mRNA in the Pfizer and Moderna vaccines does not stay in cells after it coaches the body to make the spike proteins.
No, they do NOT. There is zero chance that mRNA vaccines can alter your DNA. To alter DNA, the vaccine would need to be able to enter the cell nucleus. This is not possible since the vaccine contains no signals to be able to do this.
