這是藥商 Valneva 實驗中的疫苗 - VLA2001，有網友表示他們最終做"完"的時間是在2022年中，但預計在今年9月就公布報告，並在今年Q3申請EUA ：

Study To Compare The Immunogenicity Against COVID-19, Of VLA2001 Vaccine To AZD1222 Vaccine (COV-COMPARE)

Brief Summary:

This is a multicentre, randomized, observer-blind, active-controlled, superiority, study to compare the immunogenicity of VLA2001 to AZD1222 in terms of GMT.

Approximately 4000 participants will be recruited in the study. About 3000 participants aged 30 years and above will be randomized in a 2:1 ratio to receive 2 intramuscular recommended doses of either VLA2001 (n=3000) or AZD1222 (n=1000). In addition, approximately 1000 subjects aged 18-29 years will participate in this study in a non-randomized, open-label fashion to receive VLA2001. The 2 doses of vaccination for both vaccines will be administered 28 days apart, on Days 1 and 29. All visits will be conducted at the clinical site on an outpatient basis.

雖然現在還不知道結果會如何，但無疑的還是有其它藥商在研發新冠肺炎疫苗。
