Government expert consultant and Chair Professor of the Department of Microbiology of the University of Hong Kong, Yuan Guoyong attended the online lecture of the Hong Kong Society of Pediatrics today (7th).
He suggested that doctors and nurses should pull the back syringe briefly before injecting Fubitai vaccine to eliminate the inhalation of blood and ensure that the needle will not be accidentally inserted into the blood vessel, so as to reduce the risk of myocarditis in the vaccinated person.
He also suggested injecting in the thigh, "If I get the third shot, I will have a big bun. I am older and may not be good at heart."
Yuan Guoyong said frankly that the best vaccine research technology is the mRNA used in the Fubitai vaccine. The second is the recombinant protein technology used by Novavax.
He believes that the method of groove needle is worthy of consideration. No research has found that two doses of different vaccines will have serious and long-term adverse effects.

Yuan: Those who vaccinate Kexing need to get the third shot sooner
The Delta variant virus is raging around the world. Yuan Guoyong said frankly that it may not be possible to prevent the spread of the virus through vaccination, and the concept of establishing an "immune barrier" is no longer feasible.
He took Kexing Vaccine as an example. If Hong Kong is to build an "immune barrier", 142.9% of the citizens need to complete the vaccination, which is impossible.
However, he emphasized that Fubitai and Kexing vaccines can still reduce the risk of severe illness or death, thereby reducing the pressure on the medical system. He called on all qualified persons to vaccinate.
When asked if the third injection should be given, Yuan Guoyong said that the antibody will drop over time, and if the amount is too low, it can cause serious illness.
He pointed out that the antibodies produced by Forbitux can be maintained for 8 months or even more than a year, and the general public does not need supplementary injections for the time being; while the antibodies produced by Kexing vaccine will last for a shorter period of time, and he expects that the vaccinators will need faster Get the third shot.
He also pointed out that many countries are administering the third dose of vaccine to the public. For example, Israel has already started the third dose of vaccination. Hong Kong can refer to their research data for consideration. There is no need to rush for a while.

Young thigh injections can reduce immediate strenuous exercise
The team led by Yuan Guoyong conducted research in mice earlier and found that an intravenous injection of Fubitai vaccine produced four and five times more cardiac enzymes two days later than intramuscular injections. Therefore, the heart cells of mice are easily damaged and appear obvious. Myocarditis and pericarditis.
However, he emphasized that the dose ratio of mice vaccinated is much higher than that of humans, so the risk of the vaccine to its heart cannot be compared.
However, in order to reduce the risk, he recommends that doctors connect the syringe shortly before the injection to eliminate the inhalation of blood and ensure that the needle will not be accidentally inserted into the blood vessel.
He also suggested injecting the vaccine in the thigh to reduce the risk of the vaccine entering the blood vessels. "If I get the third shot, I will have a big bun. I am older, and my heart may not be good." He said with a smile, the young man is in the thigh. A few days after the injection, it is difficult to move, and it is difficult to exercise vigorously immediately.

Finger ditch needle practice is worth considering
When asked whether Kexing’s vaccination age should be lowered, Yuan Guoyong said that 100 million young people around the world can start considering vaccination, because the hearts of people aged 12 to 16 are still growing and they do not want to affect them; The epidemic will not cause serious illness, so there is no need to rush.
As for whether pregnant women should be vaccinated, he pointed out that the number of injections for pregnant women is not high. For the sake of safety, it is still recommended to get the injections only after delivery.
Yuan Guoyong said frankly that the world's best vaccine research technology is the mRNA used in Fubitai vaccine, followed by the recombinant protein technology used by Novavax.
He believes that the method of groove needle is worthy of consideration, and the temporary study has not found that two doses of different vaccines will have serious and long-term adverse effects.
