It can be called B plan.
Some reasons
1 If there's no time to develop a regular vaccine.
2 It's relatively mild.
3 Vaccinate on proper body parts such as corneal that may cause less side effects.
Why is the corneal?The event of professor wangguangfa infected with virus is a excelent sample.
1.1There is a relatively clear time for infection and cure(January 14th-30th).
1.2 He weared a N95 mask and no goggles.
1.3 He's eye discomfort first and then there are some upper respiratory symptoms.
1.4 His symptoms are relatively mild for people around 60.
Professor wangguangfa's Self description
The expert group is not equipped with goggles, because it is generally not needed, but if there are more patients, the local virus concentration is relatively high, the ventilation is not good, and the space is narrow, under the promotion of these conditions, it is possible to infect through the mucous membrane. It's just a conjecture.
The day after I returned to Beijing, I was in a meeting at that time. I felt something wrong with my eyes. I took a look at the camera of my mobile phone and my eyes were red. Then there were symptoms of the upper respiratory tract, stuffy nose, mild runny nose, sore throat, and then fever and chills.
Why is the corneal?
1.1 People can be infected with the virus through it.
1.2 Thickness and absence of blood vessels and tissue structure , etc may provide sufficient buffer for the virus.
1.3 The immune system of the virus will also build up quickly(It took Professor wangguangfa about 16 days to recover .).
1.4 The cornea is relatively far away from the lung that being infected can be very serious.
All above are conjectures.It needs to be confirmed by data.
4 Use immunizations by spraying.
5 Vaccinate specific groups of people like young Doctor and Nurse.
