Until very recently, vaccines against the virus that causes COVID-19 were not allowed in young people under the age of 16 years. We need safe and effective vaccines to protect this population, allow schools to open, and to help protect everyone else (this is called herd immunity).
The vaccine produces a very good immune response in this age group
In a major international clinical trial, researchers compared two shots 21 days apart of the Pfizer vaccine with placebo (dummy vaccine) in 2,260 volunteers aged 12 to 15 years. Similar to other age groups, the vaccine worked in the participants and was safe with only mild side effects. For example, 79 to 86% of participants had pain at the site of the shot, 60 to 66% of participants had fatigue, and 55 to 65% had headaches. There were no serious vaccine-related reactions. Compared to older children and young people 16 to 25 years of age, the immune response against the virus was even better in 12-15 year olds. For those who never had a COVID infection before, there were no new cases after the second dose. For those in the placebo group, there were 16 new COVID-19 infections after the second “dummy” shot. This means the vaccine was 100% successful.
This shows that the Pfizer vaccine works and is safe for young people (12-15 years).
