Called 'latent period than conventional strains to increase even more than 1000 times shorter amount of virus' research results to the delta stock of the new coronavirus that can also be reported, announced the CDC research results existing vaccine is that it is still valid .. The study published by the CDC was conducted in two periods: April 4-June 19, 2021 before the Delta epidemic in the United States, and June 20-July 17 after the Delta epidemic. , It is to calculate the infection rate, hospitalization probability, and mortality rate in each age group.
Regarding the infection rate, before the epidemic of the Delta strain, the infection rate of unvaccinated persons was about 11 times higher than that of those who completed vaccination (95% confidence interval was 7.8 to 15.8 times). After the epidemic of Delta strains, the result was about 4.6 times (95% confidence interval 2.5 to 8.5 times). The probability of hospitalization was 13 times higher for those who had not been vaccinated before the epidemic (11.3-15.6 times for the 95% confidence interval) and 10 times higher for those who had not been vaccinated (8.1 to 13.3 times for the 95% confidence interval) after the epidemic. The mortality rate was 16.6 times (95% confidence interval 13.5-20.4 times) before the epidemic and 11.3 times (95% confidence interval 9.1 to 13.9 times) after the epidemic.
'The findings suggest that the vaccine may be less effective against the new coronavirus and that it may still have a strong effect on hospitalization and death,' the paper said. However, there are some caveats. One caveat is that the reduction in vaccine efficacy against Delta strains is greater in the elderly aged 65 and over. A study of approximately 33,000 adult infected individuals transferred to emergency departments and emergency clinics found that vaccine efficacy was approximately 89% between the ages of 18 and 74, but only 76% between the ages of 75 and older. I did. A study of about 1,000 people taken to five veterans' medical centers also found that the vaccine reduced the probability of hospitalization between the ages of 18 and 64 by 95%, a reduction in this probability of hospitalization of 65. Only 80% were over the age of.
Due to the epidemic of the Delta strain, the number of newly infected people and the number of new deaths have exceeded 100,000 every day since mid-August 2021 in the United States, and the Biden administration has made it mandatory for federal officials to vaccinate. We are strengthening countermeasures.
