欧美的情况，如果没有合格疫苗，就要看痊愈者产生的抗体了。 此Science论文有3万多个个体，5个月后大多数个体还是有中高量抗体。 Robust neutralizing antibodies to SARS-CoV-2 infection persist for months Abstract SARS-CoV-2 has caused a global pandemic with millions infected and numerous fatalities. Questions regarding the robustness, functionality, and longevity of the antibody response to the virus remain unanswered. Here we report that the vast majority of infected individuals with mild-to-moderate COVID-19 experience robust IgG antibody responses against the viral spike protein, based on a dataset of 30,082 individuals screened at Mount Sinai Health System in New York City. We also show that titers are relatively stable for at least a period approximating 5 months and that anti-spike binding titers significantly correlate with neutralization of authentic SARS-CoV-2. Our data suggests that more than 90% of seroconverters make detectible neutralizing antibody responses. These titers remain relatively stable for several months after infection. https://science.sciencemag.org/content/early/2020/10/27/science.abd7728

好消息。总算有点儿盼头了
