There are several FDA-approved vaccines that are widely available in the U.S. and around the world.
The vaccine developed by Pfizer Inc. and BioNTech SE has received full approval by the FDA. This vaccine, which shows to be more than 95 percent effective, may help prevent people 12 years old and older from getting seriously ill and hospitalized. Patients receive two doses of this vaccine 21 days apart.
The Pfizer COVID-19 vaccine is also available to children ages 5 to 11 under FDA’s emergency use authorization (EUA). The Pfizer vaccine for children ages 5 to 11 is administered in two separate doses, three weeks apart. Children in this age range receive a lower dose (10 micrograms) than individuals 12 years of age and older (30 micrograms).
The vaccine developed by Moderna Inc. has received emergency use authorization by the FDA. This vaccine, which is about 95 percent effective, can reduce infections among asymptomatic individuals and could potentially help prevent the spread of the virus from person to person. The Moderna vaccine is given to patients 18 years old and older in two different doses 28 days apart.
The Johnson & Johnson (J&J) vaccine is the third to receive emergency use authorization by the FDA. This vaccine was found to be 66 percent effective in preventing COVID-19 illness and was also highly effective in preventing hospitalization and death in those who did get sick after exposure to the virus. According to the CDC, women younger than 50 years old should especially be aware of the rare risk of blood clots with low platelets after vaccination. This vaccine is administered to individuals 18 years old and older as a single injection.
COVID-19 Vaccine Booster Shots
The U.S. Food and Drug Administration (FDA) has approved under emergency use authorization (EUA) a single COVID-19 booster shot from Pfizer, Moderna and Johnson & Johnson for vaccinated individuals over 18 years of age.
The Pfizer and Moderna vaccinated individuals who are 18 years of age and older can receive a single booster dose six months after receiving the second vaccine dose. Johnson & Johnson vaccine recipients 18 years of age and older can receive the booster dose two months after the single-shot vaccine.
