Of the approximately 400 people hospitalized in the UK due to the Delta variant (previously the second Indian), 42 people lost their lives: 23 were not vaccinated, 12 were vaccinated with a double dose, and 7 received only one dose . This is why scientists are not surprised that even some vaccinated people will become seriously ill and lose their lives due to the infection.
Around May 15, Delta variant Oh VOC-21APR-02 (predecessor The second India B.1.617.2) Become the dominant United Kingdom, After passing Alpha variant (predecessor English B.1.1.7) Is the source of the sharp increase in the number of cases and deaths last winter.based on New data from Public Health England (Plate heat exchanger), a government agency of the British Ministry of Health and Welfare, up to 96% of new infections are caused by the Delta variant, with cases doubling every 4.5 to 11.5 days, depending on the area affected. Greater Manchester and Lancashire are the most affected counties, while the most severely affected cities are Leicester, Hounslow and Bolton.British experts believe that this variant has a Communicability 60% higher than the Alpha variant; the number of new infections increased from 29,892 to 42,323 within a week, it is not a coincidence that this has also led to an increase in the number of people (controlled by the vaccination campaign) Be hospitalized electronic death toll because Coronavirus disease, An infection caused by the SARS-CoV-2 coronavirus.Although to a lesser extent, patients are also involved Full vaccination.
PHE data Guardian quote Shows that between early February and early June, approximately 33,000 cases of Delta variant infection were recorded in the UK; less than 20,000 cases occurred in unvaccinated subjects, and 7,500 cases occurred in subjects vaccinated with a single dose , 1,800 cases occurred among subjects who received double-dose vaccination.As known in clinical studies, a single dose of Covid vaccine AstraZeneca (Vaxzevria) or di Pfizer-BioNTech (Comirnaty) There is a function around 30% Against asymptomatic Delta mutation infection, 14 days after the second vaccination, AstraZeneca’s protection rate rose to 66.1%, and Pfizer’s mRNA vaccine’s protection rate rose to 93.4%. No vaccine is 100% effective, so it is not surprising that some fully vaccinated people may be infected or even seriously ill.
383 people Be hospitalized Of those diagnosed with Delta mutant coronavirus infection, 251 people (65%) were not vaccinated; 86 people (22%) received a single dose of the vaccine, and 42 people (10%) received two doses of the vaccine. Among all hospitalized patients, 42 died within 1 month after diagnosis: 23 (54%) were not vaccinated; 12 (28%) were fully vaccinated, and 7 (16%) received only one dose. These data indicate that even people who have been vaccinated may become seriously ill and lose their lives due to COVID-19, although this proportion is very low (but experts predict). The latest data released by the U.S. Centers for Disease Control and Prevention also proves this point (CDC) Americans, of whom approximately 100 million are fully immunized (as of April 30, 2021), of which 10,000 have been infected with the coronavirus, 1,000 have been hospitalized, and 2% have died (but not always due to pandemic pathogens) .
“We expect vaccinators to be infected occasionally,” Dr. William Schaffner, a vaccine expert at Vanderbilt University in Nashville, told the New York Times. “There is no vaccine in history that is 100% effective. Vaccination is our best choice to avoid serious and critical illness. Just as not everything in medicine is perfect,” Paul O, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia Professor Fett responded.More Delta variants circulating in the UK Spreadable And possibly more Provocation And it’s more toxic than the Alpha it replaces, so it’s no surprise that a small number of people cannot win the battle against the virus even if they are vaccinated.
