In the past few days, the new crown epidemic has been on the rise, putting pressure on epidemic prevention and control. The good news is that the first domestically produced new crown specific drug has been approved for marketing, but the high price has attracted people’s attention. , What is the difference between the role of the manufacturer’s claim to prevent new crown infection and the preventive role of vaccines? Let’s take a look.
We noticed that this special drug is actually a neutralizing antibody, and the main component is ambavirumab/romisevirumab. If the vaccine is injected into the body, the effect is to stimulate the body to produce Antibodies, then the effect of this drug is equivalent to injecting antibodies directly into the body. Antibodies are the main grip for our body to fight against the new coronavirus and remove it from the body. It is also the first link of the immune clearance mechanism for the new coronavirus. The lack of antibodies means The body’s ability to resist and prevent the new crown will be greatly reduced. If the body does not produce antibodies after the injection, it means that the injection was unsuccessful.
So we can clearly see that the two have their own advantages. The antibodies produced by the injection of the new crown vaccine into the human body are persistent and have a long-term preventive effect, but it needs a process to work. , It takes effect after the antibody is generated in the body, and the effect of neutralizing antibody is effective in a short period of time, and it is immediate, so the injection of the drug can not only treat the new crown, but also prevent the close contact personnel from contracting the virus in a short period of time. If vaccination is equivalent to cultivating internal skills to improve one’s own power, hitting neutralizing antibodies is equivalent to hitting chicken blood in a short period of time, and the power will temporarily increase but cannot be sustained.
Neutralizing antibodies are not only used for the treatment of new crowns. my country is a big country with hepatitis B. In the past, mother-to-child transmission was an important way of hepatitis B infection. It will be infected by the virus in the mother’s blood through the mucous membranes of the eyes, nose, nose and other parts. At this time, the hepatitis B neutralizing antibody can be injected immediately to remove a small amount of hepatitis B virus entering the baby’s body, and then the hepatitis B vaccine can be injected to allow the baby to produce antibodies on its own. , which is the difference between neutralizing antibodies and vaccine prophylaxis.
Generally neutralizing antibodies belong to biological preparations. Most of the preparation processes are complicated, the cost of raw materials is much higher than that of small molecule drugs, and the investment in pre-clinical trials is relatively large. The price at the beginning was relatively high, and the corresponding foreign drugs are currently priced at around 13,000.
