No change in Covishield dose gap: NTAGI

Dr NK Arora, chairman of the Covid-19 working group of National Technical Advisory Group on Immunisation (NTAGI), on Saturday ruled out any change in the gap between two doses of Covishield, saying scientific studies suggest higher efficacy when the interval is longer.

“Any further changes would be based only on scientific evidence and not on random demands,” Arora said. Several states, including Kerala, Karnataka and Maharashtra, are keen to reduce the interval, which is currently 84 days.

Arora said data from the vaccine tracker platform indicated that the way the Covishield doses are being administered is fine.

‘Consider cutting Covishield gap for some’

Therefore, there was no need to change it as of now, he said, adding that the vaccine’s effectiveness in the current interval is being monitored constanty. Virologist T Jacob John differed a little, saying the Covishield dose gap could be reduced to four weeks for senior citizens and individuals at high risk. “They (authorities) should at least think about it,” he said.

Explaining his thought, the retired professor and the head department of clinical virology and microbiology of Christian Medical College (Vellore) said, “If someone wants early immunity, give the second dose at four weeks. But if you want the maximum possible immunity, wait for 84 days. Two doses save lives. So, for individuals at high risk of severe disease and death, four weeks’ interval is the best. For them, protection delayed could mean protection denied. For all others aged between 18 and 60, the 84-day interval is logical.”

Dr MK Sudarshan, chairman of the Karnataka government’s Covid-19 technical advisory committee, said they had recommended the Karnataka health minister to reduce the time gap of Covishield doses to about six weeks because there were sufficient vaccines but not enough second dose takers. “There is enough scientific evidence that one to two months’ gap is effective,” he said.

Theatres & auditoriums to reopen in Maha from Oct 22

A day after the Maharashtra government announced reopening of schools and religious places, CM Uddhav Thackeray on Saturday approved the reopening of cinema halls and auditoriums in the state from October 22. A detailed Standard Operating Procedure (SoP) is still being compiled and will be issued by the government in the next few days. The decision was taken following a meeting of Thackeray with filmmakers, members of the state Covid task force and senior state officials. Cinema and theatre professionals welcomed the CM’s announcement to restart halls on October 22. Stage artistes were especially pleased that their reopening was advanced from the earlier appointed date of November 5.

No need to vaccinate children for reopening schools, says Dr Arora

There was no need to vaccinate children for reopening schools, said NTAGI task force chairman Dr NK Arora. “What is important is to vaccinate parents, teachers and school staffers before the resumption of physical classes,” he said.

The vaccination of healthy children would commence next year, but the immunization of children with comorbidities would start next month, Dr Arora said. He said they were finalising the list of comorbidities in this age group and it would be ready in the next 8-10 days. Virologist Dr T Jacob John said the priority of vaccination for children was not high and schools should reopen before the immunization programme was rolled out.
