'Someone may have diabetes, but at what level the disease qualifies as a comorbid condition is something a doctor will decide upon and certify accordingly.'
If the vaccine is recommended for use as a booster against Omicron, it may significantly boost the demand for Covishield in India.
As the Omicron variant of Sars-CoV-2 takes centrestage, vaccine makers in India are of the view that scaling up the existing vaccines to make them more effective is possible.
After ramping up production to meet the steep demand spike during the Covid-19 pandemic, Indian medical device makers are now struggling with idle capacity. According to industry estimates, around a third of the installed capacity, especially for consumables, disposables, small-ticket electronic items, etc., is lying unutilised. Sample this: India used to produce just 6.24 million pieces of PPE kits per annum before the pandemic, but by June this was ramped up to 233.87 million pieces per annum.
A nasal vaccine, one expert said, is a "fantastic idea" for two reasons -- one, it can potentially create sterile immunity, and two, it is easy to administer and thus scalable.
Will syringe shortage puncture India's Covid vaccine plans?
In September, Bharat Biotech aimed to supply 35 million doses, and take this up to 55 million by October. This is still less than what the Indian government expects from the company.
Pfizer can show the FDA approval to the Indian regulator and present a case that based on whatever data submitted, the US regulator has granted a full marketing nod, says Sohini Das.
The Centre is looking to procure around 1 billion syringes between September and December to support the COVID-19 vaccination drive.
Gennova has also got permission for phase-2 and 3 clinical trials for its lyophilised mRNA vaccine for injection from the subject expert committee advising the Central Drugs Standards Control Organisation, reports Sohini Das.
Government institutions and pharma industry are examining if a 'cocktail' approach to making a multi-variant Covid-19 vaccine works against multiple strains of the ever-mutating virus, reports Sohini Das.
The health system is trying to ensure that it isn't caught by surprise -- the way it was last time. So, hectic preparations are on.
While Lupin is working on a Remdesivir powder for inhalation, Glenmark has tied up with a Canadian Biotech firm for nitric oxide nasal spray that reduces Sars-CoV-2 viral load and thus transmission.
If things go according to plan, the vaccine would be available in the market by the end of this year.
Adar Poonawalla said he was hopeful that Covovax, the Novavax vaccine made by SII, will be launched around October this year for adults and for children by the first quarter of next year, depending on DCGI approvals.
India is not keen to 'bow down' to demands related to indemnity against legal liabilities in case any vaccine recipient develops severe adverse reactions post inoculation.
While Covishield supplies would meet the target of 500 mn doses between August and December, it looks like Covaxin would miss the target of 400 mn unless the partner sites of Bharat Biotech ramp up very rapidly, reports Sohini Das.
But no extra risk after second dose, shows study led and funded by drug maker, reports Sohini Das.
'The Centre is planning to procure five million vials of Remdesivir ahead of the third wave. What's better is that this time, the government is paying us in advance,' said a senior executive of a Mumbai-based pharma player which makes Remdesivir. Sohini Das reports.
So far, no other vaccine has been approved globally for children below 12 years. Sohini Das reports.
