Booster Covid dose being deliberated: Govt

December 07, 2021 17:23

Studies to understand the duration of persistence of SARS-CoV-2 antibodies have been undertaken in India and abroad by multiple independent investigators and vaccine manufacturers and scientific evidence on it is still evolving, the Rajya Sabha was informed on Tuesday.

In written reply to a question in the Upper House of Parliament, Minister of State for Health Bharati Pravin Pawar said that in addition to antibodies, other immune mechanisms like cellular or T cell based immune response and memory B cells are created because of vaccination and are responsible for protection against infection.

She was responding to the question on whether the government has conducted any studies to check if there is a case of declining vaccine immunity amongst the elderly population.

Asked whether the government is considering giving booster shots to improve immunity, Pawar said, "The National Technical Advisory Group on Immunization (NTAGI) and the National Expert Group on Vaccine Administration for COVID-19 (NEGVAC) are deliberating and considering scientific evidences related to dose schedule of COVID-19 vaccines and the need for booster dose."

Adequate doses to vaccinate all eligible first dose and due second dose beneficiaries aged 18 years and above by December 2021 have been made available to states and union territories, she said. PTI
