I have no problem with the Russian vaccine. I think the Chinese Sinovac sounds pretty good too.Pfizer and Moderna (company ticker symbol MRNA) are both MRNA vaccines. This MRNA is the newest technology and in some people, might show some serious allergic reactions. - this is why I'd prefer traditional vaccine like Sputnik with 92% protection or JNJ's one with 72% ... I know you guys have prejudice against Russia, but all of us got dozens of Russian vaccines and we are still alive
Sinovac is a very traditional vaccine made with dead or inactive virus.
What I'm hearing from medical friends though (including a few doctors who've gotten the shot) is that they think the Pfizer vaccine is best. The cold storage requirement has been relaxed as well, so the Pfizer shots are becoming more feasible. Canada is going to get massive shipments of them soon.
