Pune: The National Technical Advisory Group of Chairman of Immunization Dr.
N K Arora told TOI that Russian Vaksin Sputnik V might not be able to enter the government’s inoculation site until the supply increased substantially.
Explain the reason behind the delay of supply, Arora said, “Sputnik V uses two different adenovirus as a virus vector.
The first shot contains Adenovirus 26 (AD26) as a virus vector, while the second contains adenovirus 5 (AD5).
The second dose making is a process Slow because the AD5 virus grows very slowly.
Because the second dose takes time to produce, inventory has been postponed.
The first dose of vaccine will only be available when the second shot inventory increases.
“So far, only a few doses of lakh vaccines are available for use in India.
Some private hospitals have run out of the first dose of vaccines, sources at one facility at Pune told Wednesday.
Dr.
Arora said that some viruses grow very slowly in controlled conditions, including adenovirus 5.
“The virus has been used in the past for candidate vaccines and has caused the same problem.
Sputnik V availability so far in India is not high enough to combine it in a free vaccination program Government, “he said.
Vaccines must be stored at -18 ° C for stability and potential.
Apart from Russia, only India produces vaccines, he said, adding that the manufacturing process has begun in India, but the problems in increasing the production of the second dose are experienced here and also in Russia.
