Covid-19 has infected more than 1 crore people and killed 1.5 lakh so far. On Sunday, the Drug Controller General of India (DCGI), the country's national drug regulator, gave nod to two coronavirus vaccines for restricted emergency use - Serum Institute of India's Covishield and Bharat Biotech's Covaxin.Drugs Controller General of India, VG Somani said, "We will never approve anything if there's slightest of safety concern. Vaccines are 110 % safe. Some side effects like mild fever, pain & allergy are common for every vaccine."That's not all, the DCGI also approved Cadila Healthcare Ltd to conduct Phase 3 clinical trials of its ZyCOV-D vaccine candidate for Covid-19. In the coming weeks, the Pfizer vaccine and Russia's Sputnik-V are likely to be approved for use in India.
Dosage

- In late-stage trials, two full doses were given to the majority of participants in the UK and Brazil and were shown to be 62% effective - but a smaller group of volunteers received by accident half a dose followed by a full dose, and registered 90% effectiveness.
