Batman:Handle9: You can opt for whichever vaccine you like however availability is an issue.
There are some economic incentives here to be vaccinated. In government workplaces if you aren't vaccinated you need a weekly PCR at your own expense, if you are vaccinated this is paid for by the state. Many private employers are following suit. I'd say within a year you won't get a residency visa unless you are vaccinated.
Sinopharm is by far the most widely available and most popular. Pfizer is rare as hen's teeth and Astra-zenaca, which is what I have had, somewhat available. Anecdotally Sinopharm has by far the least side effects. Despite the efficacy of Astra-zenaca being somewhat less effective it is still excellent at mitigating the serious effects of COVID. Anecdotally the newer variants are much nastier and most people want to be vaccinated.
When you are driving into oncoming traffic you aren't too concerned about whether you wear a lap belt or a 5 point racing harness. You put on the seat belt you have available.
i'm not sure if that's a good thing: does it means it doesn't do anything. (no side effects = no immune response?)
The publicised efficacy from the stage 3 trials here was 86% and 79% in China. They haven't published any data so it's unclear how that lines up with the western vaccines. It's an inactivated virus vaccination so pretty old technology.
Anecdotally I don't know anyone who has been vaccinated with Sinopharm and has gotten covid. I know a lot of people who were not vaccinated and got covid so take that as you will.
