Named a way to double the chances of asymptomatic development of COVID-19
British doctors have found that vaccinated patients are about twice as likely to tolerate COVID-19 asymptomatically and 66 percent less likely to need hospitalization than sick people who have not received the vaccine. Such conclusions are named in the journal Lancet Infectious Diseases.
So, the chances of developing asymptomatic forms of COVID-19 rose by 63 percent after the first dose of the vaccine and by 94 percent after the second. “Vaccinated patients were 70 percent less likely to be hospitalized compared to those who did not receive the vaccine,” the study said.
British doctors led by Claire Steves, a senior researcher at King's College London, found that only 0.5 percent of people vaccinated with a single dose of the drug contracted the coronavirus, and 0.2 percent fell ill after a full course of vaccinations.
Scientists also recorded a sharp decrease in the incidence of overt forms of COVID-19 and in the likelihood of long-term symptoms of infection. Moreover, both of these indicators were about 1.5-2 times lower among vaccinated Britons than among people who had not yet received the vaccine. Patients were also about 70 percent less likely to be hospitalized with two doses of the vaccine.
Earlier, the deputy director for scientific work of the Central Research Institute of Epidemiology of Rospotrebnadzor, Corresponding Member of the Russian Academy of Sciences, Alexander Gorelov, said that 82 percent of those who had the infection developed protection against coronavirus. A study by Rospotrebnadzor showed that almost every fifth Russian who had been ill with COVID-19 – 18 percent – did not develop antibodies.
