Initial research to assess vaccine efficacy using specific animal models of COVID-19, such as ACE-2 transgenic mice, other laboratory animals, non-human primates, indicates a need for implementation of biosafety level 3 containment measures for handling live viruses, and international coordination to ensure standardized safety procedures.
Utafiti wa mapema wa kutathmini ufanisi wa chanjo kwa kutumia mifamo maalum ya covid-19 ya wananyama, kama vile ACE2 yenye jeni kutoka kwa panya, wanyama wengine wa maabara, na chembe zingine zisizo za kibinadamu, unaonyesha hitaji za hatua za uzuizi wa kiwango cha 3 cha usalama wa chembe za kuambukiza, na uratibu wa kimataifa ili kuhakikisha taratibu sanifu za usalama.
