Why do we need the fourth dose of vaccine?

With the counterattack of the epidemic across the country, the media announced that the fourth dose of the new crown vaccine is coming soon. After injection, this vaccine can not only add "partners" to the human body's immunity and improve the body resistance of the elderly, but it can also fight against volatile viruses and reduce the mortality rate of infected people. It is of great help in our fight against the epidemic. Help

1. It can add "partners" to human immunity and improve the body resistance of the elderly. The recurring COVID-19 epidemic has brought inconvenience to many people’s lives. Most people in our country have received three shots of the COVID-19 vaccine on time and have developed a certain degree of resistance in their bodies. But as time goes by and the new coronavirus mutates crazily, the efficacy of these three shots of the vaccine is obviously not enough.

Under this situation, the fourth dose of vaccine is also on the agenda. According to media reports, the fourth dose of vaccine is a booster shot, which is not much different in nature from the third dose of vaccine we injected. But its effect is very strong. After entering the human body, it adds a "partner" to the body's immunity. It can quickly identify, neutralize or kill viruses, adding another layer of protection to the human body.

Especially for the frail and sick elderly, it is imperative to get the fourth shot. As many elderly people grow older, some of them suffer from high blood pressure, diabetes and other diseases. If they are infected by the new coronavirus, they can easily cause complications. This fourth dose of vaccine can improve their resistance and help them build an "immune wall" in their bodies.

2. Fight against the variability of viruses and reduce the mortality rate of infected people. Nowadays, the number of infections in many places across the country is rising sharply, all caused by mutated viruses, and the fourth dose of the vaccine is to combat this newly mutated virus. Research shows that the newly launched fourth shot of the vaccine is very effective and can increase the body's antibodies fivefold. Only with sufficient antibodies can we effectively fight against the volatile virus and reduce the probability of the human body being infected with the new coronavirus.

In addition, after receiving the fourth dose of the vaccine, even if you are unfortunately infected with the virus, the antibodies in the body will help the body quickly return to a healthy state, which can greatly reduce the rate of severe illness and reduce the risk of infection. mortality rate, and its protective effect on the human body is self-evident.

Summary: Although the fourth dose of the vaccine has not yet become popular, its enhanced efficacy will definitely help us improve our resistance and alleviate the pressure the epidemic has brought to people everywhere.
