First Baby Born with Antibodies Against Coronavirus.

#GS-3 #SCIENCE AND TECHNOLOGY #PRELIMS FACT

Pediatricians have reported the first known case of a woman who gave birth to a baby with antibodies against the novel coronavirus. She was given the first dose of the COVID-19 vaccine during her pregnancy.

Key Points

  • As per a yet-to-be peer-reviewed study, the mother had received a single dose of the Moderna mRNA vaccine at 36 weeks and three days of her gestation period.
  • The study was posted in the preprint server medRxiv.
  • Three weeks later, the woman gave birth to a healthy and vigorous girl.
  • The blood sample taken immediately after the birth of the baby revealed the presence of antibodies against the SARS-CoV-2 virus.
  • The co-authors of the study Paul Gilbert and Chad Rudnick from Florida Atlantic University in the U.S then reported it as the first known case of an infant with SARS-CoV-2 IgG antibodies detectable in cord blood after maternal vaccination.
  • The woman, who has been breastfeeding the baby exclusively, received the second dose of the vaccine as per the normal 28-day vaccination protocol timeline.
  • While earlier studies have shown that the passage of antibodies from COVID-recovered mothers to their fetuses via the placenta was lower than expected, the current research suggests “potential for protection and infection risk reduction from SARS-CoV-2 with maternal vaccination.”

However, the co-authors note that further long-term studies are required to quantify the antibody response in babies born to vaccinated mothers.

The pediatricians wrote that the protective efficacy in newborns and ideal timing of maternal vaccination remains unknown. They have urged other investigators to create pregnancy and breastfeeding registries as well as to conduct efficacy and safety studies of the COVID-19 vaccines in a pregnant and breastfeeding woman and their offspring.


 

CSIR-NIO PROJECTS TO MAP GENETIC DIVERSITY IN INDIAN OCEAN 

#GS-1 #GEOGRAPHY 

The Council of Scientific and Industrial Research-National Institute of Oceanography (CSIR-NIO), Goa, has started a project for mapping the genetic diversity of organisms and the effect of micronutrients and trace metals on them in the Indian Ocean. The project is supported by the CSIR, under one of its flagship projects TraceBioMe.

Key Points

  • The project envisages extensive sampling of water, plankton sediments, and different organisms in various parts of the Indian Ocean with an aim to study the presence of different kinds of organisms and the trace metals and micronutrients found therein.
  • Modern state-of-the-art molecular techniques as well classical techniques will be used to trace and study the different kinds of organisms.
  • In the 1st phase of the project, microscopic organisms will be investigated.
  • A 90-day long expedition onboard research vessel RV Sindhu Sadhana with 30 scientists took off from Visakhapatnam on March 15.
  • The expedition will be completed in two-legs till the end of May. It will cover over 9,000 nautical miles, and end in Goa.
  • The data generated under this program will help to achieve the SDG14 goals, which aim at conserving and sustainably use the oceans, seas, and marine resources.
  • Scientists from the CSIR-NIO have set out on a mission to identify and characterize the genes and proteins in the ocean to understand the cellular-level operations of organisms in the ocean by utilizing emerging biomedical techniques, such as proteomics and genomics.

This study will enable scientists to identify the factors controlling the changes in RNA and DNA in the oceans and various stressors impacting them. They will also be used as tracers to track the causative factors and suggest possible solutions for their mitigation impacting society. In addition, these large pools of RNA and DNA libraries of the oceans would be utilized for future bioprospecting in the Indian Ocean for human benefit.
