On December 8 of last year, the UK started the world’s first general vaccination against the new vaccine against coronavirus infection (Corona 19), which changed some of its vaccination guidelines, generating controversy.
The first and second vaccination intervals have been extended to 12 weeks.
Different vaccines are even recognized
FT “Mixed safety and efficacy cannot be verified”
Astra vaccine today the world’s first vaccine
The Pfizer, Bioentech, AstraZeneca and Oxford vaccines, which the UK approved for emergency use on December 4 and December 30, respectively, must be vaccinated twice at 3- and 4-week intervals, respectively.
However, the Financial Times (FT) recently introduced a revised bill allowing ‘mixed vaccination’, saying: “Cross administration of different vaccines is allowed for the first and second vaccination” in the Green Paper containing guidelines. for vaccination, said the Financial Times (FT). Reported days. The revised guidelines allow people who received the Pfizer vaccine in the first dose to switch from the second dose to the AstraZeneca vaccine.
FT noted that the corona vaccine guidelines from the US Centers for Disease Control and Prevention (CDC) recommended that “two vaccines should be completed with the same product” and that “the safety and efficacy of use of vaccines has not yet been confirmed. Because ”, he explained.
The New York Times (NYT) quoted Professor John Moore of Wail Cornell University School of Medicine as saying: “There is no data on vaccine combination (the safety and efficacy of the vaccine).” “The British government is only trying to avoid the current situation, not scientific judgment. It seems urgent,” he said.
As the controversy grew, Mary Ramsay, Head of Immunization at the Health Department of England (PHE), said: “Combination vaccines are very limited in very rare cases where the same vaccine is not available or (in the first vaccination) is not known I will. ”
The UK previously announced a policy to increase the interval between two vaccine administrations from 3 to 4 weeks to 12 weeks on the 30th of last month, and the controversy continues.
Pfizer, a vaccine developer and manufacturer, made a statement, saying: “As a result of the phase 3 clinical trial, the efficacy and safety of the vaccine administered at 21-day intervals was confirmed, but there is no data on the vaccination case. after exceeding that interval “. The British Medical Association (BMA) also issued a statement noting: “Increasing the interval between vaccinations is an unfair measure for those who already have a second vaccine, such as the elderly or those with underlying diseases, and it is not easy to change the interval suddenly. .
Anthony Pouch, director of the National Institute of Allergy and Infectious Diseases (NIAID), told CNN: “If you look at the data from clinical trials, the 21-day interval is optimal for Pfizer.” “I don’t like (the British government’s plan).”
The UK government’s long vaccination interval or mixed vaccination method appears to be an obstacle to the intention to somehow defeat the spread of Corona 19 by first inoculating as many people as possible. With the spread of the mutant virus, which has a strong spread of around 70%, the UK has more than 50,000 confirmed cases a day for five consecutive days from December 29 to 2.
Meanwhile, according to The Guardian and others for 3 days, the UK will start vaccinating AstraZeneca and Oxford for the first time in the world from the fourth day (local time) in major hospitals and GP hospitals. Korea plans to introduce this vaccine starting in February.
