FDA Expands Pfizer Vaccine Authorization for Ages 12-15
Written on
Chapter 1: Exciting News for Teens
In a pivotal announcement just in time for summer, the U.S. Food and Drug Administration (FDA) has broadened the emergency use authorization for the Pfizer-BioNTech Covid-19 vaccine, now allowing its use for children aged 12 to 15 years. This development is particularly encouraging for teens eager to return to a more conventional lifestyle.
According to the FDA, the Pfizer vaccine has met the necessary safety and effectiveness standards for this age group. Prior to this, it was only approved for individuals aged 16 and older.
Section 1.1: Efficacy of the Pfizer Vaccine
Pfizer recently shared promising results from their phase 3 clinical trial, which demonstrated that the vaccine achieved 100% effectiveness and elicited a robust antibody response in the 12-15 age bracket. This trial involved 2,260 participants from the U.S., revealing only 18 cases of Covid-19, all of which occurred in the placebo group. None of those who received the vaccine contracted the virus.
Subsection 1.1.1: Common Side Effects
The side effects observed in children mirrored those seen in adults. Common reactions included pain at the injection site, fatigue, headaches, chills, muscle aches, fever, and joint discomfort.
Section 1.2: The Changing Landscape of Covid-19 in Children
Historically, Covid-19 infection rates among children have been low, and many remain asymptomatic. However, they can still transmit the virus to adults, including parents and teachers. The emergence of variants such as B.1.1.7 has shifted perceptions regarding the impact of Covid-19 on younger populations. A recent outbreak linked to youth sports in Minneapolis highlighted the rapid spread of infections among children, prompting public health officials to take notice.
Chapter 2: The Data Behind the Decision
As per the FDA's release, the CDC has recorded 1.5 million Covid-19 cases among children aged 11 to 17. Data from the American Academy of Pediatrics reveals that over 3.85 million children have tested positive for the virus since the pandemic began. Thankfully, the majority of children who contract SARS-CoV-2 tend to recover well, with mortality rates among children ranging from 0.00% to 0.21%.

Experts are in consensus that vaccinating children is crucial in curbing the further spread of Covid-19 and is an essential step towards achieving herd immunity in the U.S.
Like other vaccines, the Pfizer vaccine does not contain a live virus, which means individuals cannot contract Covid-19 from the vaccine. The mRNA technology used does not interact with the cell nucleus and does not change a person's DNA. Furthermore, these vaccines do not require adjuvants to boost their effectiveness.
Immunity is not instantaneous following vaccination; it takes time for the body to develop protection. The Pfizer vaccine necessitates two doses: the first dose prepares the immune system, while the second dose enhances the response.

Clinical trials indicate that the Pfizer vaccine offers 95% efficacy one week after the second dose, while the Moderna vaccine provides 94% immunity at least two weeks after the second dose. After completing the vaccination regimen, individuals can feel considerably safer, though the risk of severe disease remains, albeit low.
