Understanding the COVID-19 Vaccines
Learn more about Adolescents and COVID-19 Vaccines
Since the COVID-19 pandemic began in March 2020, we have been bombarded with sometimes confusing information about COVID-19 care and prevention. Like many, adolescents and young adults – and their parents – have struggled to understand available information to make the best decisions for themselves. This resource is here to help answer your questions.
What do I need to know?
There are three vaccines authorized in the U.S. for COVID-19, but only one of the three is authorized for adolescents and young adults -- the Pfizer-BioNTech COVID-19 vaccine, which is authorized for people ages 5 years and older.
The Pfizer-BioNTech vaccine is administered with two shots, scheduled at least three weeks apart. Completing two shots is called completing the primary dose. It takes 2 weeks after the primary dose for the body to build protection against the virus that causes COVID-19.
Some people have reported arm soreness at the injection site, which generally goes away quickly. Some people experience short-term side effects after being vaccinated, such as tiredness, headache, or chills. These side effects may affect your ability to do daily activities, but they typically go away in a few days. These are normal signs that your body is building protection.
The CDC recommends that all people 12 and over receive a booster shot five months after their primary dose. A booster shot makes additional antibodies 24-48 hours after vaccination. Side effects to the booster dose are similar to the primary dose. You are considered up-to-date when you have received all recommended COVID-19 vaccines, including boosters.
How do vaccines work?
Vaccines work with your body’s natural defenses to safely develop immunity to disease. They familiarize your immune system with a specific disease-causing invader, or pathogen. Then your immune system recognizes and makes antibodies to that pathogen to fight the disease if you are infected in the future. Different vaccines do this in different ways by using different forms of the pathogen -- for example, a weakened (attenuated), inactivated, or component of the pathogen.
Importantly, vaccines don’t make you sick with the pathogen they’re designed to protect you from. Instead, they give your immune system a practice run at counteracting a weaker, inactivated or partial version of the pathogen.
What can you do to protect your teen?
Talk to your health care provider. They are ready to answer your questions and address your concerns.
Get members of your household the COVID-19 vaccine as soon as you can. The vaccine is the best protection against serious COVID-19 illness.
