  • Ancovax is India’s first animal vaccine against SARS-CoV-2 virus.
  • It is vaccine for animals like dogs, lions, leopards, mice and rabbits.
  • It is an inactivated vaccine (killed vaccine) developed using the antigen (infectious part) of the Delta variant.
  • In addition, it uses Alhydrogel as an adjuvant to boost the immune response.
  • This vaccine is capable of neutralizing both Delta and Omicron variants.
  • It was developed by the Indian Council of Agricultural Research-National Research Centre on Equines (ICAR-NRCE).
  • The aim of the vaccine is to protect endangered animals such as lions and tigers.
  • The vaccine can protect pets, and animals in the zoo.
  • It can also prevent transmission of disease from companion animals to the humans.

Kits Launched

  • Prior to Ancovax, Russia had registered the world’s first COVID-19 vaccine for animals called Carnivac-Cov in 2021.
  • It generated antibodies against the COVID-19 virus in dogs, cats, foxes and mink.
  • The vaccine contains an inactivated SARS-CoV-2 virus strain to elicit humoral and T cell-mediated immune responses in the animals.
  • The vaccine has been developed to prevent animal-to-human viral transmission.

  • Pseudomogrus sudhii is a new species of jumping spider of the salticidae family.
  • This species inhabits dry grass blades of the desert.
  • This species of jumping spider was found in the Desert National Park.
  • It is the first report of this genus from India. So far, 35 species of spiders of this genus have been discovered worldwide.

Aerosol Study on Transmission of Covid-19

The Aerosol study of the transmission of SARS-CoV-2 gives insight into the transmission characteristics of the novel coronavirus in air in hospital settings and in residential areas and public places.

  • Sampling - A machine, which sucks in air, fitted with a filter on which a gel was spread was taken and worked in the target areas.
  • The samples collected from the filter were either
    1. Used to carry out an RT-PCR test to determine the presence of the virus, or
    2. Cultured by infecting vero cells in the lab (to find out if the collected virus samples were infectious).
  • Findings - Virus was found in samples collected from COVID-19 wards.
  • Outside, in the corridors and near the hospitals the virus was not detected, implying a dilution or removal of the virus.
  • Having separate COVID-19 wards and negative pressure rooms are good, because infection does not spread very far.

Negative pressure rooms are isolation wards in hospitals to keep persons with infectious diseases.

  • The virus was detected even 20-25 feet away from infected persons.
  • This means it is in the air for quite some time. That is why this study confirms that this virus is spreading through air.
  • The virus was detected when they sampled the air in the toilet even 2 hours after an infected person had used it. So, when using public toilets, masks should not be removed, even if no one is present.
  • In a closed space, physical distancing alone is not helpful, because the virus borne on droplets can travel upto 20-25 feet.
  • So, people should have their masks on, in closed space, even if they are 6-10 feet away from infected person.
  • Air cleaning and circulation in closed rooms is important. Sterilization filters may be employed for air conditioning.
