Latest debate: How long does immunity against COVID-19 last after vaccination?

Reports of health agencies in parts of the world considering a booster dose against fading immunity, particularly among the elderly, even after two doses of vaccine, has raised the uncomfortable question in India, which is struggling to vaccinate its vast population.

Several experts from Karnataka argued against the need for a booster dose while saying that “a breakthrough infection itself will act like a booster dose”.

A human body produces better antibody response against COVID-19 through natural infection than a third dose of vaccination,” said Dr. Mudassir Azeez Khan, Head of Community Medicine at Mysore Medical College and Research Institute (MMC&RI).

Longer inter-dosage interval may offer better immunity

COVID-19 vaccination with an inter-dosage interval of 10-14 weeks elicits a stronger immune response than when the vaccine is delivered at an interval of 4-6 weeks, a study done amongst a closely followed patient cohort in Kochi has reported.

The difference in immune response, when the interval between shots is extended, is more than three-fold. The longer the gap between the two shots, the higher the levels of anti-spike protein antibody response produced. This essentially means that two doses of vaccine delivered at a longer interval is likely to give stronger and longer-lasting immunity against COVID-19, says Padmanabha Shenoy, a clinical immunologist and rheumatologist at Kochi, who led the study.

Schools set to reopen in Kodagu on September 17

The long wait of students has finally ended as the schools and colleges in Kodagu are set to reopen for resuming physical classes for the first time this year in the wake of the Test Positivity Rate (TPR) falling below 2% in the district. The classes will resume from Friday.

The government had not permitted schools and colleges to reopen in Kodagu in view of the worrying TPR, which was above 2% for a long period. Thus, even as schools reopened in other districts, they remained closed in Kodagu. Kodagu’s proximity to Kerala was another reason the State went slow on reopening schools.

Classroom teaching for students of classes VI to X and PU will begin from Friday as government, aided and unaided schools will reopen. All PU colleges will reopen for offline classes.
