Cod vaccines provide solid protection against hospitalization and death when infected with the disease, but are not very effective in treating long-term symptoms.
This was revealed in a study conducted by Washington University in the United States.
Previously, medical experts had expected that the risk of a person contracting cocaine after using the vaccine would be significantly reduced.
But research published in the journal Nature Medicine found that vaccine users had a 15 percent lower risk of developing long-term infections than non-vaccinators.
Research has shown that vaccines work best for the purpose for which they were developed, to prevent serious illness and death, but their effectiveness against long codes is not great.
The researchers said that cod vaccines were developed within the first year of the epidemic and that until then doctors, scientists and patients were unaware of the presence of long cod and therefore were not designed to protect against long-term symptoms.
“We now know that the virus can have long-term effects and we need to review vaccines,” he said.
The study used national health data from the US Department of Veterans Affairs.
This was the data of approximately 34,000 people who became infected with COD after vaccination and more than 113,000 people who did not use the vaccine who became infected with COD between January and October 2021.
After overcoming the disease, these individuals were examined for 6 months to see if they were experiencing long-term symptoms.
Research has shown that the use of vaccines does not provide much protection against long codes, but they are more effective in preventing some of the more dangerous long-term symptoms.
According to research, the use of vaccines reduces the risk of long-term lung diseases by about 50% and the risk of blood clots by 56%.
The researchers said that not everyone had the long-term symptoms of cod, but only 10 per cent of those who became ill after vaccination had long cod, but since the number of patients was so high, 10 per cent was too high. Seem.
The study did not examine the effects of booster doses, but researchers said that one should not expect too much difference from booster because vaccines are not designed to protect against long code.
“We need to consider additional measures to protect against the long-term effects of the virus,” he said.
