Corona 19 vaccine is not very helpful in preventing the aftereffects of breakthrough infection

There have been no studies that have shown the exact relationship between vaccination and sequelae.

Although the COVID-19 vaccine is effective in preventing infection and severe conversion, it is pointed out that the breakthrough infection is not very helpful in preventing sequelae compared to those who are not vaccinated.

According to the international scientific journal Nature today (27th) local time, in a Facebook survey conducted by an American law firm, 44 out of 1950 vaccinated people had breakthrough infections, and more than half of them, 24, suffered from various sequelae. confirmed to be suffering from

In addition, 40% of respondents said that the aftereffects they suffered after receiving the COVID-19 vaccine improved, and 14% said their symptoms worsened.

However, because this questionnaire was not randomized, it was found not to be suitable for use in determining the proportion of post-vaccination breakthrough-infected patients with sequelae.

However, Nature explained, “In any case, realistically, it shows that there are people suffering from aftereffects among the breakout infections.”

Meanwhile, a survey of approximately 1,500 vaccinated health care workers in Israel identified 39 breakthrough infections, of which 7 (19%) had sequelae lasting more than 6 weeks.

In addition, a study conducted at King’s College in the UK found that the vaccine only halved the risk of lasting sequelae for at least four weeks if a person who received a breakthrough infection was infected.

The King’s College research team particularly noted that 11% of those infected without the vaccine complained of sequelae, and 5% of those infected with breakthrough infections had sequelae.

Claire Steve, a professor at King’s College, said, “Although the proportion of patients with sequelae among breakthrough infections is rather small, the existence itself is meaningful.

In addition, although the results of the study have not yet been peer-validated, there are also analyzes that this situation will worsen in the future.

The University of Oxford, England, compared the electronic medical records of infected people after only receiving the flu vaccine with about 10,000 breakthrough infections and found that the COVID-19 vaccine did not protect those vaccinated against some sequelae.

According to statistics released by the British government in October, a single dose of the COVID-19 vaccine reduced the number of reported sequelae cases by 13%, and a second dose decreased by an additional 9%.

So far, there have been no studies that have accurately determined the correlation between COVID-19 vaccination and sequelae.

But as the number of sequelae continues to rise, Congress last December allocated $1.15 billion to the National Institutes of Health (NIH) to study the long-term health effects of COVID-19 infection on citizens.

The NIH announced that it will conduct a follow-up study on the causes and consequences of COVID-19 infection sequelae among more than 10,000 citizens for four years.
