Can antibody tests determine if the COVID-19 vaccine was effective?
The Centers for Disease Control and Prevention (CDC) discourages antibody testing for assessing immunity after getting the vaccine.
A vaccinated person is very likely to get a negative result from a serology test, even if the vaccine was successful and protective. That’s because different serology tests detect antibodies to different parts of the virus.
打的是P疫苗，打第一针时胳膊酸痛了一个晚上，除此之外没有其它任何反应。听说反应越小效果越差，出于好奇，在打完第二针一个月后，去做了antibody test，这是结果：
按压注射位置有痛感，早上起来就不疼了。第2针仍打在左胳膊，注射位置酸痛的程度比第1针还轻, 左胳膊没有疼感。

不知道对比其他人打同样疫苗，或者别的疫苗结果如何
每次抽血时都不敢看，所以到底抽了多少不清楚。
