I don't know where to ask this, Google throws propaganda at the question.
For reasons of travel, I now have to be vaccinated to enter a certain country. So if one has to choose, which is safest?
EDIT - just to clarify, by safe I mean less likely to damage. Vaccine effectiveness isn't a variable here.
It's important to know that even traditional vaccines can cause serious issues. Proper testing removes the ones with higher risk, which along with all the propaganda is why just saying something is a vaccine means it's good in the west. Countries that receive less tested vaccines, or even rejects don't have as positive results.
A live polio vaccine mutating and becoming the leading cause of polio in the world is a recent example. ADE (Antibody Dependent Enhancement) and other issues can also occur.
I haven't done any research on Sinovac or Covaxin, so I'm not saying there are problems with them, but if you're going to take one, try to find evidence of the risks and effectiveness (including over time).
People infected with SARS nearly 20 years ago have t-cell resistance to SARS-Cov-2, which is 20% different (far higher % than any SARS2 variants). This may mean a vaccine with a more complete pathogen would be more effective and longer lasting, but research is where you find out if it actually is.
Yes, by safe I mean less likely to damage. Vaccine effectiveness isn't a variable here.
