Killer T lasts longer than B, about 150% times as long from what I read, but they also disappear after 6 months to 1 year. That's why people catch cold / flu every year, year after year. Only smallpox, polio, measles antibodies last a life time.

Faster than Pfizer. About 3 months to 6 months, compared to 6 months to 1 year.
There is a strong and prolonged rhinovirus surge following school opening which keeps coronavirus at bay. Just wait till November or December, this year's coronavirus surge is going to be nasty.
All of the vaccines starts to wane a few weeks after the 2nd shot. Maybe it is just some fundamental science that immunity decays overtime. But sitting in the US, i found it ludicrous that the government dropped most facemask/social distance requirements so early by claiming such high efficacy rate. We already had Trumpers not believing in covid, now we have liberals also believing in inaccurate/massage covid information. I told my friends everyone should wear facemask around march2020, but they said the guberment say facemask was useless. I told my friend in june2021 that the vaccine doesn't seem to be that great but they said "I believe in the science" (the marketing lingo used by Biden)

No point talking to the Americans. They think differently than Chinese.
