Municipal Disease Control Experts Analysis of Harbin Harbin 60 -year -old new crown pneumonia case in Harbin

On the 20th, the reporter interviewed Luo Chao, the director of the Immunization Planning Institute of the Harbin Disease Control and Control Center, analyzed the vaccination of vaccine in the new crown pneumonia case in the city over 60 years old.

Luo Chao said that after the elderly infected with the new coronal virus, the proportion of severe and death was the highest among all the ages of all crowds, with three main reasons.

The first is that the elderly are weakening with their age. The second is that for the elderly, after generally infected viruses or bacteria, the incidence of autoimmune incidence increases, and it is more prone to inflammatory reactions. Third, most elderly people have basic diseases. If the virus is infected, it will also cause the symptoms of the original disease to be more serious, or it is more prone to complications.

Therefore, the global immune strategy has always taken vaccines for the elderly and people with basic diseases such as chronic diseases as a priority group. The new crown vaccination rate of the elderly is relatively low, coupled with the influence of basic diseases, to increase the vaccination rate of the new crown vaccine for the elderly, especially the increase in the inoculation rate of strengthening needles.

Luo Chao introduced that from the analysis of the new crown epidemic cases from February 28 to early May this year, it can be found that a total of 1,373 positive infected people are 171 elderly people over 60 years old. Among 171 elderly positive infections, 116 people were vaccinated for 3 doses of new crown vaccines, 19 people were vaccinated with 2 doses, and only 6 were vaccinated with only one dose. Of the 36 positive infections who were not completed throughout the process, 10 people were general, asymptomatic and asymptomatic of 26 people, accounting for 27.7%and 72.3%, respectively. Among the 135 positive infected people who were vaccinated with more than 2 doses, 23 people were ordinary, asymptomatic and asymptomatic 112, accounting for 17%and 83%, respectively. Among the 116 people who completed 3 doses, only 18 of the 116 people, with a normal type of only 18 people, and 98 asymptomatic asymptomatic, accounting for 15.5%and 84.5%, respectively.

It can be seen that the elderly over 60 years old, after completing the entire process of immunity, especially after strengthening immunity, even if the new crown virus is infected, most of them are mild and asymptomatic infected. The existing vaccine has a more obvious protection effect on the severity of the new coronary pneumonia, which can effectively reduce the incidence and mortality after the infection. Therefore, it is necessary to supplement the shortcomings of the current vaccination rate of the elderly, and vigorously improve the vaccination rate of the elderly, and achieve "depletion", "should be connected", "should be connected quickly" as soon as possible.
