Both Sinovac and Astra have been finalized and approved as shown in your link.

There's nothing strange about it. Vaccines have been politicized based on political views instead of scientific views so I tend not to look at published efficacy rates.

Not true. Sinovac is recognised in these countries so you can consider these countries instead https://www.schengenvisainfo.com/news/eu-travel-covishield-sinopharm-sinovac-vaccines-are-most-widely-accepted-by-eu-countries-after-those-authorised-by-ema/ Austria Cyprus Finland Greece Iceland Netherlands Spain Sweden

As long as both types of vaccines are recognized in that country as approved vaccines, it shouldn't be a problem.
