Why should people aged 12- 17 be vaccinated with COVID-19 vaccine?

The function of vaccine is to make a certain proportion of people produce immune antibodies (COVID-19 original strain, about 60% to 70% of people can achieve group immunity by vaccination with efficient vaccine. Delta strain needs about 85% population vaccination) to achieve group immunity, the virus will not spread widely (of course, there will be infection). The vaccination rate of young people in a country is obviously not up to the vaccination rate (there are still many young people who do not meet the vaccination conditions), so the elderly and children should be vaccinated to meet the vaccination rate requirements.

If you want to vaccinate the elderly and children with foreign vaccines, you need to do a separate clinical trial (Phase III). For example, Pfizer and Modena have done clinical trials for the elderly and children. Several COVID-19 vaccines in China have not been independently tested in the elderly over 60 years old and adolescents and children under 65,438+07 years old. It is inappropriate to vaccinate the elderly and children directly, which violates medical ethics and is very unsafe.
