While offering vaccines, think global and ignore geography: Expert
Demand for vaccines is huge and the two shots that have been approved—Covaxin and Covishield—alone cannot meet the demand, said public health expert Gajendra Singh in an opinion piece for The Indian Express.
Globally many vaccines have proven their safety and efficacy, such as US-based Pfizer and Moderna along with Russian vaccine Sputnik V. The US ones, however, don't suit India's requirements. Pfizer and Moderna require to be stored at -70 degree Celsius, a major logistical challenge. The Russian candidate, Sputnik V, suits Indian requirements of the Indian landscape with two forms. First, a liquid form which would have to be stored at minus 18 degrees Celsius and second, a freeze-dried form, which can be stored at 2-8 degrees Celsius. The latter was developed especially for transportation to remote places. Sputnik V could be a suitable choice for Indian conditions.
