The Novavax vaccination period, which is effective against delta mutations.

I heard Novavax will soon start vaccination in Korea. Today, Novavax announced the clinical results of adolescents aged 12 to 17.

As you know, Novavax has announced 90.4% of clinical results for adults over the age of 18.

Today is the clinical results for adolescents aged 12 to 17.

The clinical trial was conducted from May 24 to September 27, 2021, and was conducted in 73 locations in the United States by randomly blind vaccinations vs placebo at 2:1. This was a time when delta mutations accounted for the majority in the United States, and all 11 people who confirmed the sequence were delta mutations.

The effect of the vaccine was 79.5%, and the antibody titer after two vaccinations was two to three times that of adults. The virus neutralization test also showed 2.4 to 4 times higher results than adults.

Novavax is planning a clinical test for younger children in the second quarter of 2022. I think the results will be announced around summer.

1. The effect of Novavax's clinical results aged 12 to 17 was 79.5% (effect on delta mutation). In the case of the Pfizer vaccine, the effect on delta mutation was known to be around 80% in the early to mid-80% range)

2. Antibody formation was 2 to 3 times higher than that of adults, and virus neutralization ability was 2.4 to 4 times higher.

3. Childhood clinical trials are scheduled for the second quarter of 2022.
