Recently, Evusheld (Enzyte), a neutralizing antibody drug that can be used for pre-exposure prophylaxis of neo-crown, has successfully passed special import approval in the Boao Le Cheng International Medical Tourism Advance Zone in Hainan, and began to be administered to the first batch of appointees in early July.
Unlike the New Crown vaccine, which induces spontaneous immunity by injecting inactivated antigens and proteins into the body, the drug supports the immune system by replenishing antibodies through neutralizing antibody therapy. Experts say that the vaccine and neutralizing antibodies can play a complementary role in the means of prevention of the new crown, which can also be understood as equivalent to a new pathway of prevention.
It is reported that the prophylaxis is indicated for pre-exposure prophylaxis of neo-coronavirus in adults and adolescents (age ≥ 12 years and weight ≥ 40 kg). And it has been shown that Enzyte reduces the risk of serious illness and death by 50.5%. In the face of the current BA.4/BA.5, the neutralizing activity of Enzid is reduced, but it still has some neutralizing activity.
On July 4, Hainan Boao Le Cheng Advance Zone Administration said: Ensiade, as a long-acting neutralizing antibody against neo-coronavirus, is preferentially indicated for the prevention of neo-coronavirus infection in people with impaired immune function or immunocompromised (including patients with malignant hematological or other tumors undergoing chemotherapy, patients on medication after organ transplantation, dialysis patients, patients with multiple sclerosis and rheumatoid arthritis who are on immunosuppressive drugs). (including patients with diseases such as rheumatoid arthritis who are on immunosuppressive drugs). In addition, the drug can provide protection for people who are ineffective with vaccines and who need additional protection in addition to vaccines.
According to known information, the prophylactic drug is still not included in health insurance and it is relatively expensive at 13,300/two shots.
The new crown epidemic has been going on for 3 years now, and over the past 3 years, it has been proven through extensive practice that vaccination is still the most effective and cost-effective means of prevention. In addition, regular nucleic acid testing for people at high risk of exposure is also an effective means of preventing serious illness and preventing the spread of the epidemic on a large scale.
The New Coronavirus Rapid Test is a highly sensitive test that uses PCR technology to exponentially replicate specific nucleic acid fragments of the virus to detect whether a sample belongs to a person who is infected at a very low viral load, detecting traces of the New Coronavirus in the early stages of human infection and bringing forward the gateway to prevention.
At this time, when preventive drugs are not yet approved and the price is high, vaccination and regular nucleic acid testing are the most effective and economical means of prevention!
