NEW DELHI, Apr 27: The Government is likely to soon reduce the gap between the second dose of COVID-19 vaccine and the precaution dose from the current nine months to six months, official sources said today.A recommendation on lessening the gap is expected to be made by the National Technical Advisory Group on Immunisation (NTAGI) which is set to hold a meeting on April 29, they said.Studies at ICMR and other international research institutions have suggested that antibody level wanes after about six months from the primary vaccination with both doses and giving a booster increases the immune response.All those above the age of 18 who have completed nine months after the administration of the second dose are eligible for the precaution dose.“Taking into account the scientific evidence and findings of the studies done here and internationally, the gap between the second dose of COVID-19 vaccine and the precaution dose will most likely be reduced from the current nine months to six months soon. A final decision will be taken based on the recommendations by the NTAGI which is set to meet on Friday,” a source in the know of the developments said.
