Second dose of covishield: Will the government shorten the vaccine dose range? – duration of dose of Indian covid-19 vaccine

The central government is preparing to shorten the interval for taking two doses of the Kovichield vaccine. Currently, the interval between taking two doses of CoviShield vaccine is 12 to 16 weeks.

The Center is known to be willing to propose reducing this to 4-6 weeks. The Times of India reports that Karnataka state government officials have said that orders in this regard are likely to be issued soon.

There has been a huge increase in the production and distribution of the vaccine. Therefore, experts advising the Karnataka government had recommended that the interval between doses of Covshield be shortened.

Meanwhile, the interval between taking two doses of Kovacs, which the government provides at no cost, is likely to continue for 4 to 6 weeks.

The Kovid-19 State Technical Advisory Committee (TAC) had written to the state government on Sunday asking the Center to reduce the interval between taking the second dose of the Kovshield vaccine.

By shortening the interval between the second dose of the vaccine, more people can be vaccinated. The committee also said that this would allow people to be fully protected from the spread of the third wave before the expected outbreak.

“It is very important to reduce the interval between taking the vaccine,” said TAC Chairman Dr. MK Sudarshan said.

‘The government had shortened the interval to provide co-shields to students abroad. This should apply to everyone, “he said.

At the time of taking the Kovishield vaccine in India, the interval between taking two doses was 4 to 6 weeks. Then it rose to 6 to 8 weeks.

When the second wave of Kovid arrived and the large-scale infection was confirmed at the time, the vaccine was delivered in small quantities. Additionally, the interval between vaccinations was extended to 12 weeks in May.

Vaccine production and distribution improved in July. Consequently, vaccination campaigns in Karnataka have increased.

On September 17 alone, 31 lakh doses were administered. The government now aims to give 12 lakh doses every Wednesday.

In Karnataka, the first dose was given to 3.8 lakh people, which is about 78% of the target. About 30 percent (1.5 million) of people are fully vaccinated with two doses of the vaccine.

Nationwide, 66 percent took the first dose of the vaccine. 22% of people take both doses. An estimated 82.4 million people have been vaccinated so far across India.

According to the central government, vaccine production is expected to increase by Rs 30 million in October. They say it will hit 100 million rupees in December.

Karnataka currently receives 1 crore dose per month. The state government expects it to reach 1.5 million rupees in October.

‘The number of people taking the first dose will be reduced from next month. This is a good time to reduce the interval between doses of Kovichield. ‘ – Said a senior official of the state health department.

The official said he had written to the central government on the matter, but was in a position to reduce the time limit.

“Based on the available evidence, the timing for taking the vaccine is being reviewed,” said Dr. NK Arora, chairman of the National Group of Experts on Vaccine Administration.

‘All decisions are based on science. Their goal is to better protect our people. The National Vaccine Tracker claims to provide 97 percent protection against death with a single dose. He added that if two doses of the vaccine had been taken, it would have been 98 percent.

Dr Arundhati Chandrasekhar, Managing Director, National Health Mission, Karnataka, said: “We are waiting to hear what the Central Government has to say on the matter.” They also say that shortening the interval between doses can speed up the vaccination campaign.
