How many people have received the new crown vaccine and have been

In the process of large-scale vaccination of the new crown vaccine, the true effect of the vaccine has always been an issue of great concern to everyone, especially whether it is possible after the vaccination and what is the probability of being infected with the new crown again.

On April 16, local time, the official website of the US Centers for Disease Control and Prevention (CDC) released data on "breakthrough cases" of the new coronavirus disease (COVID-19), which provides a large-scale real-world data reference for this important issue.

Data show that since December 14, 2020, as of April 13, 2021, more than 75 million people in the United States have completed the new crown vaccination program.

According to preliminary calculations based on this figure, the infection rate among those who have completed the vaccination is less than one in ten thousand (about 0.

According to US CDC public information, during the same period from December 14, 2020 to April 13, 2021, a total of 14.

What are the characteristics of people infected after vaccination? Preliminary data shows:

Vaccine breakthrough infection can occur in all age groups eligible for vaccination.

Of the breakthrough infection cases, 3752 (65%) were women.

1695 cases (29%) of vaccine breakthrough infections were asymptomatic.

Among the vaccine breakthrough infection cases, 396 cases (7%) are known to be hospitalized, and 74 cases (1%) have died.

Of these 74 fatal cases, 9 (12%) reported asymptomatic or died from causes unrelated to COVID-19.

Although hospitalizations and deaths are not directly caused by COVID-19, if patients have completed the vaccination procedure and subsequently test positive for the new coronavirus infection, they are still considered to be vaccine breakthrough cases.

The US CDC said that existing research is ongoing and data is being accumulated.

How to understand these data?

1.

But there is evidence that vaccination can reduce the severity of the disease.

2.
In response to these published data, the US CDC stated that the currently reported vaccine breakthrough cases may still be an underestimated number.

This is because, on the one hand, the surveillance system for vaccine breakthrough cases is “passive” dependent on voluntary reports from local health departments; on the other hand, due to lack of testing, not all vaccine breakthrough cases in the real world will be identified, especially It is in the case of asymptomatic or mild disease.

But these monitoring will help to identify the pattern of vaccination infection and provide relevant signals.

3.
These cases do not mean that the vaccine has no protective effect.
The US CDC emphasized that the new crown vaccine is still effective.

Vaccine breakthrough cases only occur in a small proportion of the vaccinated population.
There is currently a lack of demographic characteristics or vaccine characteristics of people who have been infected by a vaccine breakthrough.

The current evidence supports the effectiveness of the new crown vaccine, and it is recommended that all people who meet the vaccination requirements should receive the new crown vaccine as soon as possible.

At the same time, it is recommended that people who have completed the vaccination program still need to take a variety of measures to protect themselves and others, including wearing masks, washing hands frequently, maintaining proper social distance with others, and avoiding crowds and poorly ventilated places.
