Most of the vaccines, in general, have demonstrated their effectiveness against new variants including Delta in preventing hospitalisations and deaths. However, their effectiveness seems to be waning rapidly over time (6 to 9 months after 2nd dose), necessitating booster doses to those at high risk and to all adults if sufficient vaccine supplies are available.
In addition, a significantly higher number of short-lived vaccine reactions were reported in volunteers who received a second dose of Moderna compared to those who received two doses of either AstraZeneca or Pfizer.
Amid rising threat of ‘Omicron’ variant of Covid-19, as many as 9 girl students studying at a residential school at Dasrathpur in Jajpur district tested positive for the virus on Monday (Dec 6). Reports said that the infected girls were students of Class 6 and 9 at the government-run school.
With Omicron starting to engulf India, the third wave of coronavirus could hit the peak by February with daily cases in the country expected to reach up to 1-1.5 lakh. This information was recently shared by IIT scientist Manindra Agarwal, who is involved in the mathematical projection of trajectory of COVID-19.
The students have been kept in isolation in separate rooms on the premises of the school and undergoing treatment, informed Siddharth Shankar Swain, Angul district Collector.
The recommendations are based on evidence from 16 trials involving 16,236 patients with non-severe, severe, and critical Covid infection.
A decrease of 3,402 cases has been recorded in the active COVID-19 caseload in a span of 24 hours.
Initially, a total of 22 students of the institute were found infected with the virus. It is being suspected that the recently-held annual function UTKARASH-2021 had led to the Covid-19 spread in VIMSAR.
The second worst hit country in terms of cases is India (34,641,561 infections and 473,537 deaths), followed by Brazil (22,147,476 infections and 615,744 deaths).
On November 23, as many as 53 students of a Girl’s High School in Sundargarh district tested positive for Covid-19. The infected students were from Class 9, 9 and 10. The school was later shut for a week in order to prevent the outbreak of more cases.
While 50 per cent of the adult population in India has received two doses of the vaccine, and 84 per cent has received one dose, children are yet to be inoculated in the country.
Initially, three students tested positive and later four more. On Monday, two more tested positive. All of the infected students have been isolated and their primary contacts are also been tracked and quarantined. The infected students will be retested for Covid-19.
According to the State Health Department, more than 800 non-resident Odias (NROs) have already landed in Odisha from several Omicron-hit countries. Out of them, the government does not have information about 320 returnees, which constitutes nearly 40 per cent of the total arrivals.
As Omicron is found to have more than 30 mutations in its spike protein, the main concern over its outbreak is whether disease severity is similar, milder or more severe than with the other variants.
As many as 246 persons out of the total number of travelers who returned to Odisha from other countries after November 24 have tested positive for Covid-19.
