Following discussions about the corona virus vaccine developed by British pharmaceutical manufacturer Astrazeneca, the government of England decided to review the vaccine. The vaccine developed with the University of Oxford was announced to provide 70 percent protection against Covid-19.
The corona vaccine developed by Astrazeneca in England gave hope in the fight against the pandemic. However, criticism of the vaccine is mounting. The UK government has also decided to re-examine the vaccine.
In the statement made by the British Ministry of Health in London on Friday, “First and important step for the vaccine to meet and pass the safety, efficacy and quality standards” It was said. In the Ministry’s statement, it was noted that the vaccine review will be carried out by the UK Department of Drug Inspection.
The spokesman for the Swedish and British company Astrazeneca, which noted that the vaccine will be investigated due to doubts about clinical studies and the announced effect of the vaccine, told the German news agency dpa that “the data from the current studies on the vaccine”.
The company’s statement indicated that the effect of the vaccine, which was determined to be 70 percent as a result of the tests, could be increased with a certain dose, and the data obtained from two clinical studies with different dose.
In the combined second and third phase trials, it was stated that subjects were given a half dose and a full dose of vaccine first after one month, and the effect of the vaccine was noted to be determined in 90 percent of agreement with the intermediate results obtained here. The effect was stated to be seen in 62 percent in the third phase trials in which two full doses were applied, while the average effect was therefore evaluated as 70 percent.
Was criticized
However, experts criticize the explanation of the effect according to the result obtained when giving different doses to the subjects. The American researchers also reacted to subjects younger than 55 in the study, giving the vaccine a 90 percent effect. According to experts, older people and especially those with weak defense systems should be included in the research group.
The fact that the vaccine can be stored in refrigerators that provide cooling between 2 and 8 degrees is considered a great advantage.
British Health Minister Matt Hancock stated that they asked the Medicines Inspection Agency to evaluate the data and determine whether the vaccine studies meet strict safety standards and said: “We are working tirelessly to be in the best position to obtain vaccinations after being approved by the independent auditing agency MHRA. “
The vaccine developed by German Biontech and its US partner Pfizer and the vaccines from US-based Moderna are claimed to be about 95 percent. These companies have received billions of orders from around the world so far.
