The epidemic situation in the United States is severe, and the supply of vaccines is blocked by bad weather. Do you still need to wear a mask in 2022?

I think it is necessary to wear a mask before 2022. The epidemic in the United States is undoubtedly a very serious country, and the base of the epidemic in the United States is very large. Although the vaccine has a certain effect on the epidemic situation, it can't be guaranteed that the epidemic situation can be controlled at 100%, and masks should be worn.

The United States is the most serious country in the world, and the number of vaccines purchased by the United States is also very large. Although the United States has been hit so hard, its national strength has not been greatly affected. The ability to buy vaccines is still very secure, and the United States itself is constantly developing vaccines. As long as the vaccine cannot completely resist the epidemic, it is necessary to wear a mask in 2022.

First, the United States was the hardest hit area in the world before. The global epidemic situation exceeded 65.438+0.6 billion 65.438+0.0 billion, with the largest data contributed by the United States, and the epidemic situation in the United States reached about 30 million. Almost 30% of the confirmed cases in the world. In fact, the United States is very powerful and has a lot of wealth. But in the face of so many confirmed cases, it needs a lot of resources to play a good role.

Second, vaccines cannot play an absolute role. The research on vaccines in our country is actually excellent. Even so, the protection rate of vaccines in China is only about 80%, and the protection ability of vaccines is even lower for other countries. In fact, what I want to express here is that the vaccine can't protect 100%, and each of us needs to bear 20% of the risk of infection. This 20% possibility requires us to wear masks in the next few years.

Third, China also needs to wear masks when it has vaccines. Even if there is a vaccine, it can't play a complete protective role, so it is actually common sense in life to wear a mask. However, universal vaccination is still necessary. Only when everyone is vaccinated can the impact of the epidemic on our human society become smaller.

Because the control of the epidemic in our country is in place, many people in our country are lax about the epidemic, thinking that the epidemic is over, but the epidemic is far from over. The epidemic situation abroad still has a great influence on our domestic epidemic situation, and everyone in China must pay attention to daily protection. Only when the epidemic situation all over the world is under control can our country not be affected by the epidemic situation.
