It's not hard to see why CSL has ended production of AZ? Firstly the contract had run out, and secondly AZ has had a very much unwarranted negative attention. Now that other vaccines are available at similar cost it makes good sense to stop the production, and allow CSL to continue doing other things. I agree with you Sinovac, it's obviously a ploy to get students back. Vaccinating kids is on the cards and approvals are in the pipeline. I'm sure the science and risk assessment has been done on opening up schools etc.
If you think there's been no suitable trials done on vaccines, even though there's been a worldwide phase 3 trial done over 12 months, why is a paltry few months enough to convince you to get jabbed?
