Recommendations for vaccination depend on when a person has or had SARS-CoV-2 infection and when they received treatment.
People with a history of infection: Offer vaccination regardless of history of prior symptomatic or asymptomatic SARS-CoV-2 infection.
While there is no recommended minimum interval between infection and vaccination, current evidence suggests that the risk of SARS-CoV-2 reinfection is low in the months after initial infection but may increase with time due to waning immunity. While vaccine supply remains limited, people with recent documented acute SARS-CoV-2 infection may choose to temporarily delay vaccination, if desired. However, they should recognize that the risk of reinfection and, therefore, the need for vaccination, can increase with time following initial infection.
People with a current infection: Defer vaccination of people with known current SARS-CoV-2 infection until the person has recovered from acute illness (if the person has symptoms) and until criteria have been met for them to discontinue isolation. This recommendation applies to any vaccine,including the first and second doses of COVID-19 vaccine.
问题巧的是，上周3刚打完新冠疫苗第一针，第2天（周4）核算检测出阳性（打疫苗前周1检测结果为阴性）
问我怎么办。我拿不准。症状倒是不严重，就是头痛乏力 和咳嗽，也没有味觉丧失，胸痛，呼吸困难之类的，
像这种，现在可不可以吃VC，第2针疫苗还能打吗？还是打前测抗体再说？
另：正在患新冠的人打疫苗后，症状应会减轻还是会加重？

若病况未加重，按道理21天应能转阴了。
都是在读研究生，据说同学中，这几天已陆续发现有5位核算检测阳性的了。
