Hello, I’m hoping to get some help on this topic... my employer in SE Asia has informed us that this weekend we must have the Sinovac or if not, pay to have weekly covid tests at our own expense (approx 60gbp a time). There is no other vaccine available at present. How safe is the Sinovac, especially in relation to in the future having a different vaccine (our home country has not approved this one)? I understand it has been developed using a more traditional method of delivery using inactivated virus, unlike the others currently approved. Any advice would be helpful, I’m not even overly keen on having any vaccine but I’m sure there will be a point in time when I’ll have to have it to return home. Thanks in advance!
