New Delhi:
Interchangeability of Covid-19 vaccines is not permitted and pregnant and lactating women should not be administered the shots as they have not been part of any anti-coronavirus vaccine clinical trial so far, the health ministry said on Thursday.
In a letter to all states and Union territories, the ministry highlighted that under the emergency use authorisation, coronavirus vaccination is indicated only for 18 years and above. If required, the Covid-19 vaccine and other vaccines should be separated by an interval of at least 14 days.
"Interchangeability of Covid-19 vaccines is not permitted. The second dose should also be of the same Covid-19 vaccine which was administered as the first dose," the letter written by Manohar Agnani, Additional Secretary, Union health ministry said.
Prime Minister Narendra Modi will flag off India’s Covid-19 vaccination drive at 10.30am on January 16 with 3,006 sites where the roll-out will get under way virtually connected during the launch. The Co-WIN IT platform that will track the drive from back-end to beneficiaries is also likely to be activated with its use initially limited to central and state governments.
A dedicated 24×7 call centre — 1075 — has also been established for addressing queries related to the Covid-19 pandemic, vaccine rollout and the Co-WIN software, said an official release. “Around 100 beneficiaries will be vaccinated at each session site on the inaugural day,” the government said on Thursday.
The Co-WIN platform, central to planning, implementation and monitoring of the vaccination drive, will offer limited access to healthcare workers, enabling them to feed some data and receive information about their vaccination. The names of about one crore health workers have been prepopulated on the platform.
Co-WIN will be available to the general public in the form of an online website as well as a mobile application within a month, said Health Minsitry officials. .
Healthcare workers from government and private sectors, including ICDS workers, will receive vaccine shots during the initial phase, moving on to frontline workers.
The ministry has listed precautions and contraindications for Covid-19 vaccination along with a comparative factsheet for both the vaccines (Covishield and Covaxin) which contains information on vaccine platform, physical specifications, dosage, cold-chain storage requirements, contraindications and minor AEFIs (adverse event following immunization).
It said this information should be disseminated to programme managers across all levels and through them to cold-chain handlers and vaccinators for ready reference.
Listing the contraindications, the health ministry cautioned against administration of the vaccine in persons with a history of anaphylactic or allergic reaction to a previous dose of Covid-19 vaccine, and in those with immediate or delayed onset anaphylaxis or allergic reaction to vaccines or injectable therapies, pharmaceutical products, food items, among others.
According to the letter, in case of persons having active symptoms of SARS-CoV-2 infection, coronavirus infected patients who have been given anti-SARS-CoV-2 monoclonal antibodies or convalescent plasma and acutely unwell and hospitalised patients due to any illness, the Covid-19 vaccination is to be deferred for four to eight weeks after recovery.
"Pregnant and lactating women have not been a part of any Covid-19 vaccine clinical trial so far. Therefore, women who are pregnant or not sure of their pregnancy and lactating women should not receive COVID-19 vaccine at this time," the letter stated.
The vaccine should be administered with caution in persons with a history of any bleeding or coagulation disorder (like clotting factor deficiency, coagulopathy or platelet disorder, it said.
"Following conditions are not contraindicated for Covid-19 vaccines –persons with past history of SARS-CoV-2 infection and or RT-PCR positive illness, history of chronic diseases and morbidities and immuno-deficiency, HIV, patients on immune suppression due to any condition," the letter stated.
Prime Minister Narendra Modi will launch India's massive Covid-19 vaccination drive on January 16 via video conferencing, even as adequate doses of Bharat Biotech's 'Covaxin' and Serum Institute's 'Covishield' vaccines have been delivered across the country to all states and Union territories.
The letter also mentions mild AEFIs following vaccination for both the vaccines.
In case of Covishied, some mild AEFI may occur like injection site tenderness, injection site pain, headache, fatigue, myalgia, malaise, pyrexia, chills and arthralgia and nausea.
Some mild AEFIs in case of Covaxin include injection site pain, headache, fatigue, fever, body ache, abdominal pain, nausea and vomiting, dizziness-giddiness, tremor, sweating, cold, cough and injection site swelling.
