The world's first COVID-19 vaccine for inhalation was approved for emergency use. What is the difference?

The first inhalation vaccine in Connaught was approved and put into use, which can be used as a booster. There are some differences between inhalation vaccine and traditional vaccine in inoculation form and protection effect. It should be said that this is a good progress. Although it is not a revolutionary breakthrough, it is also greatly convenient, and everyone has improved the effectiveness of the vaccine.

In this way, it is a traditional vaccine. It is necessary to let the vaccine enter the human body by injection, and then gradually play a role. Hitting people is not a terrible thing for many people, but some people are afraid of injections since childhood. I feel dizzy and uncomfortable at the sight of needles. The inhalation vaccine developed now does not need to be injected again. Just like inhaling a little air freshener, this vaccine can be inhaled into the body by inhalation to achieve non-invasive intervention.

There has also been some progress in the protective effect, because the original way of injecting boils is to make the human body produce humoral immunity and cellular immunity. However, this inhalation vaccine can make people immune to respiratory mucosa, because the atomized drug particles inhaled into the human body will directly act on the human respiratory tract, and the main channel of COVID-19 virus infection is to infect the lungs through the human respiratory tract. This can produce better antagonistic effect, which can be said to improve the effectiveness of the vaccine to a certain extent, which is a moderate progress.

Strengthening needles may be done in the future, but the way may change. At the earliest time, vaccination was by injection, but in recent years, new methods have gradually developed. For example, by ultrasonic injection, when you feel no pain, the vaccine has been injected, for example, by inhalation, and the effect will not be affected. And painless vaccination will definitely be carried out after the booster needle. Everyone knows the possibility that COVID-19 will end soon in a short time, so this progress is a good thing.
