Yep, all they had to do was not unleash it from the government lab, but they need to keep creating new 'strains' and 'waves' until they beat the population into compliance.
I'm sure they are going to make a vaccine push, but how does a vaccine prevent against a new strain? Just like how those who get those flu vaccines have to get some new shot every year. They are just testing compliance to people accepting government mandated injectables, and this will culminate in the 'mark of the beast' and people will lap that up given as to how eagerly they are accepting these vaccine shots.
