Antibodies in Covid recovered patients last only 2-3 months

People who have recovered from Covid-19 may have antibodies only for two to three months, said a study published Thursday in Nature Medicine.

However, the conclusions might not necessarily mean that a recovered person can get reinfected, stated the authors.

The limited findings offer clues to one of the biggest questions about Covid recovery, vaccination, and serological surveys.

The Chinese study also found that asymptomatic individuals have less antibodies than symptomatic ones, a fact that could have significant bearing on vaccines.

• 傳統疫苗的有效抗體滴定度，低於自然感染。時效性取決於抗原的釋放方式，故流感等疫苗加含鋁佐劑以延緩抗原降解 -fuz- ♂ (829 bytes) () 06/19/2020 postreply 17:59:52

• 要碰運氣了，現在變異株那麽多，有強的也有弱的。前幾周的好像比較弱，病死率在下降。 -fuz- ♂ (0 bytes) () 06/20/2020 postreply 06:31:16

• 唉，“群免”實質上就是“麻木”。如同流感，每年掃蕩一圈。日子久了，便習慣了。該走的走了，剩下的無所謂了 -fuz- ♂ (0 bytes) () 06/20/2020 postreply 06:34:12
