Covid-19 might not provide as much protection. Pixabay

Covid-19 vaccines may not be fully effective in people who are suffering from obesity, as experts on Tuesday suggested that the process of healing may be slower in obese people as compared to healthy ones.

According to a report on Nature, obesity correlates with a dulled immune response to Covid-19. And vaccines for a handful of other conditions often don’t work as well in obese people, suggesting that a shot for Covid-19 might not provide as much protection as researchers would like.

“The severity of Covid-19 is potentially high in obese or diabetic people. The fact is that the immunity and the process of healing may be slower in an obese person than a healthy person,” Navneet Sood, Pulmonary Consultant, Dharamshila Narayana Superspeciality Hospital, told IANS.

“Such conditions also influence the immune system’s response to vaccines. The same is applied to the Covid-19 vaccine. But there is no study yet which strongly confirms the direct relation between Covid-19 vaccines’ effectiveness and obesity,” Sood added.

Obesity can cause chronic, low-grade inflammation, which is thought to contribute to the increased risk of conditions such as diabetes and heart disease. As a result, people who are obese might have higher levels of a variety of immune-regulating proteins, including cytokines.

The immune responses unleashed by cytokines can damage healthy tissue in some cases of severe Covid-19, according to the report. A recently released study, published in the journal Perspectives on Psychological Science, suggests that depression, stress, loneliness, and poor health behaviors can weaken the body’s immune system and lower the effectiveness of new Covid-19 vaccines.

The researchers emphasize that environmental factors, as well as an individual’s genetics and physical and mental health, can weaken the body’s immune system, slowing the response to a vaccine.

“In addition to the physical toll of COVID-19, the pandemic has an equally troubling mental health component, causing anxiety and depression, among many other related problems. Emotional stressors like these can affect a person’s immune system, impairing their ability to ward off infections,” said the researcher of the study Annelise Madison from the Ohio State University in the US. Health experts also suggest that there are several factors that may lower the effectiveness of new Covid-19 vaccines and therefore it should be avoided.

“Immune system of people with severe health conditions and low immunity may influence the response to the vaccine,” said Jyoti Mutta, Senior Consultant, Microbiology, Sri Balaji Action Medical Institute, New Delhi.

“People on steroids, severe liver diseases, uncontrolled diabetes, or with immunosuppressed conditions like cancer patients, severe kidney patients may come in this category. Also, alcohol consumption should be avoided. If one is leading a healthy lifestyle there is no apparent contraindication,” Mutta added. (IANS)

Surgeons attached a pig kidney to a pair of large blood vessels outside the body of a deceased recipient so they could observe it for two days, and the kidney did what it was supposed to do.

Scientists temporarily attached a pig's kidney to a human body and watched it begin to work, a small step in the decades-long quest to one day use animal organs for lifesaving transplants.

Pigs have been the most recent research focus to address the organ shortage, but among the hurdles: A sugar in pig cells, foreign to the human body, causes immediate organ rejection. The kidney for this experiment came from a gene-edited animal, engineered to eliminate that sugar and avoid an immune system attack.

Killer Smog in Delhi.

Developed by the Indian Institute of Tropical Meteorology (IITM), Pune, a Decision Support System (DSS) that extends the ability of the existing air quality early warning system (AQEWS) to have decision-making capability for air quality management in Delhi-NCR was launched on Tuesday.

The website for the DSS (https://ews.tropmet.res.in/dss/) is designed to help the Commission for Air Quality Management for NCR and Adjoining Areas (CAQM) by delivering quantitative information about the contribution of emissions from Delhi and its 19 surrounding districts; the contribution of emissions from eight different sectors in Delhi; and the contribution from biomass-burning activities in the neighbouring states.

These information would assist in managing the air quality in a timely manner, a release from the Ministry of Earth Sciences said.

The need was stated by the CAQM, which was formed by the Ministry of Environment, Forest and Climate Change, during a meeting held in January 2021.

Recently, the Commission reviewed the progress made by IITM and had in principle approved the current version of DSS for air quality management in the Delhi-NCR. The IITM has also developed a new website for DSS with the entire system made operational, the release said.

Union Minister of State for Earth Sciences, Jitendra Singh, while launching the website for AQEWS on the occasion of 'Azadi Ka Amrit Mahotsav' week organised by the Ministry of Earth Sciences, said, "DSS is a significant contribution to 'Azadi Ka Amrit Mahotsav' on behalf of MoES and IITM and suggestions are invited on this issue."

The website also has a feature whereby the users can create their own emission reduction scenarios (from 20 different districts, including Delhi) so as to examine the possible projected improvement in air quality in Delhi for the next five days.

"This information would explicitly highlight the most important emission sources responsible for the degradation of air quality in Delhi and suggest possible solutions to ameliorate the same. With a plethora of quantitative data, the AQEWS integrated with DSS could become a user-friendly tool for air-quality management in and around Delhi," the release said. (IANS/JB)
