Am I safe? Are the people who care and take care of me safe? What impact will this situation have on my daily life? (adsbygoogle = window.

This is a comfort to parents, but it does not mean that we should be complacent. Even if children are only mildly infected, they can still be transmitted to adults, and adults may have more serious complications.

And, unlike a new drug, plasma cannot be manufactured in millions of doses; its availability is limited by blood donations.

The durability of human immunity produced by different viruses is not the same. Some will have a life-long protective effect, and some have very limited immunity. There is no definite result for the immunity of the new coronavirus, but through observation of the immunity of other coronaviruses, it can generally be maintained for 6 months to 12 months. Even if the new coronavirus does not have life-long protection, as long as there is a certain period of protection, multiple vaccination with a certain frequency can achieve the protection effect, said by Wu Zunyou recently in a public press, Chief Expert of Epidemiology of Chinese CDC
