Booster到底可不可以打？

下面两个回答都是从moh网站copy来的，感觉还漏了一种情况。

如果一个人曾经art阳性，但是无症状，自己做家隔离休息，过几天再测就ok了，那这种算是recovered from COVID-19吗？按理说算，但是只有PCR阳性才是政府认可的吧，自己测的，现在根本没法提供证据呀。

莫非当成unknowingly来处理？　

　If I have recovered from COVID-19, and have been vaccinated, do I still need to take the booster dose?A:

At present, persons who have recovered from COVID-19 and were fully vaccinated before their infection, do not need a booster dose.

Recovered persons who were unvaccinated, or partially vaccinated before their infection, should receive one dose of mRNA vaccine at least 3 months after infection to reduce their risk of reinfection, as part of their primary series vaccination. No additional booster dose is recommended at this time.

Are there any safety concerns if I had unknowingly recovered from COVID-19 but take the booster dose?

A:

There are no additional safety concerns with taking the booster vaccination if you had unknowingly recovered from a past infection. There is no known evidence that the vaccination of recovered persons causes over-stimulation, autoimmune disorders or other safety concerns.
