เนื่องจากเราเพิ่งฉีดวัคซีน ASTRAZENECA ไปเมื่อวันศุกร์ที่ 16 ก.ค. วันนี้ก็เลยขอลองเข้าไปดูเว็บไซท์ของ WHO ซะหน่อย ว่าเขาพูดถึงวัคซีนแต่ละตัวว่าอย่างไรบ้าง
How efficacious is the vaccine?
SINOVAC (2 JUNE)
A large phase 3 trial in Brazil showed that two doses, administered at an interval of 14 days, had an efficacy of 51% against symptomatic SARS-CoV-2 infection, 100% against severe COVID-19, and 100% against hospitalization starting 14 days after receiving the second dose.
ASTRAZENECA (11 FEB)
The AZD1222 vaccine
against COVID-19 has an efficacy of 63.09% against symptomatic SARS-CoV-2
Longer dose intervals within the 8 to 12 weeks range are associated with greater vaccine efficacy.

28 days after inoculation Janssen Ad26.CoV2.S was found to have an efficacy of 85.4% against severe disease and 93.1 % against hospitalization.
SINOPHARM (10 MAY)

The Moderna vaccine has been shown to have an efficacy of approximately 94.1 per cent in protecting against COVID-19, starting 14 days after the first dose.
