Hospitalization chances reduce to 0.06% following COVID vaccination: study

On Saturday, an observational study conducted by the Indraprastha Apollo Hospital has found out that 97.38 percent of those vaccinated are protected from a COVID infection. It added that the hospitalization probability post-inoculation is just 0.06 percent.

The study aimed at evaluating the ‘Breakthrough COVID infections’ (infections post-immunisation). It was carried out on healthworkers (who reported the Indraprastha Apollo Hospital in Delhi) having symptomatic COVID infection, during first 100 days of inoculation drive. Exclusively, the study was conducted on those who took Covishield jabs.

Group Medical Director of Apollo Hospitals Group, Anupam Sibal said, “India has witnessed a huge increase in cases in the second wave of COVID-19 recently, amidst the vaccination drive that is in progress. There have been reports of infections after the vaccination, which are also known as Breakthrough Infections. These infections may occur after partial and full vaccination in some individuals.”

The study findings are expected to publish in a peer-reviewed medical journal.
Dr. Sibal is also senior consultant for Paediatric Gastroenterology. He took note that as per the study, inoculation doesn’t provide 100% immunity, however, it reduces the chance of infection. He added, “Even after full immunization it protects against serious manifestations. Our study demonstrated that 97.38 per cent of those vaccinated were protected from an infection and hospitalisation rate was only 0.06 per cent. The results of the study show that break-through infections occur only in a small percentage and these are primarily minor infections that do not lead to severe disease. There were no ICU admissions or death. Our study makes the case for vaccination stronger.”

The study surveyed 3235 healthworkers, of which 85 had tested COVID positive post-immunisation. Out of them, 65 workers were fully inoculated, whereas 20 were partially inoculated. It was noted that more number of females were affected than the males. However, age did not influence the chance of infection.

One of the key authors of this study, Dr. Vaishya explained that COVID-19 jabs take time to develop suffice immunity in the human body. 

He said that present studies have found out that human body takes atleast two weeks to develop proper immunity after second dose of inoculation. It is really important to take all the necessary precautions and preventive measures even after vaccination, in order to cease breakthrough infections, Vaishya noted.

“In many people, a sense of security creeps in after the vaccination, partial or full, leading to avoidance of COVID appropriate behaviour like not using face masks, social distancing, and hand sanitation. This increases the risk of re-infections. Even after vaccination, it is essential to continue to take precautions to avoid any chance of exposure to the novel coronavirus,” he added.

Experts suggest that people should get inoculated as soon as possible, because at present, it is the only way to minimise deaths and curb COVID infections.

Eventually, this study accentuates the fact that COVID jabs have great capability to minimise infections, and reduces breakthrough infection percentage to 0.06%. However, people still need to follow all the safety guidelines such as wearing mask, maintaining social distancing, avoiding crowds and sanitizing hands, even after being fully inoculated.
