Pune: First signs of ‘herd immunity’ in small population groups.



A new study has revealed that approximately 85 per cent of people who were found infected with COVID-19 in an earlier sero survey have developed protective antibodies. The latest finding is the result of a follow-up study done in five areas– consisting three or four municipal wards each of Pune district of Maharashtra.

According to a report of a News Paper, the sero survey conducted in July and August in Pune, found that, on average, about 51 per cent of the people had been infected with the deadly virus.

The sero surveys which were conducted in several Indian cities estimated the extent of the disease by testing for antibodies among surveyed population groups. However, the presence of antibodies only indicates that the surveyed person has been infected with the disease at some point in time and does not mean that the person has also acquired immunity against the disease.

Speaking to the portal, Dr Gagandeep Kang, one of the co-authors of the study said,”  I don’t think we can still say that Pune has achieved, or is reaching, herd immunity. But the study is important because it shows that wherever there was high sero-positivity, the incidence rate has fallen subsequently,” Dr Gagandeep Kang, one of the co-authors of the study whose preprint was released on Thursday, said. The study is still to be peer reviewed.”

Notably, Pune circle’s (comprising Pune, Solapur and Satara districts) fatalities remained in the double-digit level with 48 fatalities, taking the death toll to 10,387, while daily infections increased by 1,246 to 442,117 cases.

Earlier last week, the Directorate of Health Services had asked officials to ramp up testing in Maharashtra as the second wave of the pandemic is likely to hit the city in January-February 2021.



Health Ministry say’s for COVID-19 vaccin,No vaccination for pregnant, lactating women at this time.



The Union Health Ministry has informed all states and union territories that interchangeability of COVID-19 vaccines is not permitted, and pregnant and lactating women should not be administered the shots as they have not been part of any anti-coronavirus vaccine clinical trial so far.

The Drugs Controller General of India (DCGI) had recently granted emergency use authorisation to two COVID-19 vaccines – Covishield, developed by Oxford University and British-Swedish company AstraZeneca, and manufactured by the Serum Institute of India (SII) and Bharat Biotech’s Covaxin.

India will launch its COVID-19 vaccination drive from January 16 in what Prime Minister Narendra Modi has called the world’s largest inoculation programme.

Ahead of the vaccination drive, in a letter to all states and UTs, the ministry highlighted that under the emergency use authorisation, coronavirus vaccination is indicated only for 18 years and above.

Around three lakh healthcare and frontline workers will be inoculated at 2,934 sites across the country on the first day of the nationwide vaccination drive.

The ministry has already said that getting vaccinated for COVID-19 will be voluntary.

A consignment of an anti-COVID vaccine comprising its 93,000 doses reached Himachal Pradesh’s capital Shimla on January 14, said State Health Secretary Amitabh Avasthi. The consignment of Covishield vaccine had been airlifted from Pune to Chandigarh, from where it was brought to Shimla by road, he said.

A consignment of 18,500 COVID-19 vaccines, to be used in the first phase of inoculation, arrived in Aizawl from New Delhi on the day.

The first consignment of 32,000 doses of COVID-19 vaccine arrived in Arunachal Pradesh in a vaccine van from Guwahati on the day.

Nagaland received its first consignment of 26,500 doses of COVID-19 vaccine, said an official. The vials arrived from Delhi at Dimapur Airport in an aircraft, he said.

A Maharashtra government official has said it will take six to seven months for the vaccine to become available for those who are not in the high-risk category.

Around 1.62 lakh COVID-19 vaccine has reached all the 24 districts of Jharkhand for the scheduled first phase of the vaccination drive on January 16, according to a top Health department official.
