Studies show that 30 PCs lose vaccine-acquired immunity after 6 months

Hyderabad: A new study on Wednesday showed that about one in three people lose immunity six months after taking jabs, even after record vaccination rates, as cases of covid infections increase. rice field.

These individuals are primarily over 40 years old, have comorbidities such as hypertension and diabetes, and have revealed a study led by AIG Hospitals with the Asian Healthcare Foundation.

These people are at increased risk of SARS-CoV-2 infection because their antibody response tends to be significantly reduced 6 months after being completely vaccinated.

The findings highlight the need for boosters for these vulnerable people after six months.

“Infections are on the rise across the country. Fortunately, the severity of the disease is mild due to multiple factors, including the effects of vaccination, the unique characteristics of the mutant itself, and the innate immunity between populations. “AIG Hospitals Chairman D Nageshwarlady said in a statement.

“This study aims to provide a long-term understanding of the effectiveness of current vaccines and to see if there are specific demographics that require urgent booster immunity,” he added. ..

The study was conducted in a large pool of 1,636 fully vaccinated health care workers.

The researchers measured IgG anti-S1 and IgG anti-S2 antibodies against SARS-CoV-2 in all participants.

An antibody level of 100 AU / ml was estimated to be the minimum level of protection against the virus. This means that individuals with antibody levels below 100 AU / ml are susceptible to infection.

People with antibody levels below 15 AU / ml were considered antibody negative. This means that they did not develop protective immunity against the virus.

Of the total, 6 percent did not develop any immune protection, Dr. Lady said.

The results clearly show that the decline in immunity is directly proportional to age. This means that younger people have more persistent antibody levels than older people.

Currently, there is a 9-month gap in booster doses, benefiting 70% of the population who can maintain adequate antibody levels for more than 6 months.

“But given the size of our country, we also consider 30% of people, especially those who have comorbidities such as high blood pressure and diabetes and are more likely to develop infections 6 months after being fully vaccinated. Should be a prophylactic dose, “Lady added.
