One in four people experiences mild, short-lived systemic side effects like headache, fatigue, and tenderness after receiving either the Pfizer or AstraZeneca vaccine, according to a new study published in the journal Lancet Infectious Diseases. Most side effects peaked within the first 24 hours following vaccination and usually lasted 1-2 days, and majorly among women under 55 years of age, said researchers from the King’s College London.

“The data should reassure many people that in the real world, after-effects of the vaccine are usually mild and short-lived, especially in the over 50’s who are most at risk of the infection,” Tim Spector, Professor of Genetic Epidemiology at the varsity.”The results also show up to 70 percent protection after 3 weeks following a single dose,” Spector said.

The team analyzed data from 627,383 users of the ZOE Covid Symptom Study app who self-reported systemic and local effects within eight days of receiving one or two doses of the Pfizer vaccine or one dose of the AstraZeneca vaccine between December 8 and March 10. The findings showed 25.4 percent of vaccinated people indicated suffering from one or more systemic (excluding the area where the injection took place) side effects, whereas 66.2 percent reported one or more local (at the injection site) side effects.

About 13.5 percent of participants reported side effects after their first Pfizer dose, 22.0 percent after the second Pfizer dose, and 33.7 percent after the first AstraZeneca dose. The most reported systemic side effect was headache — 7.8 percent of people after the first Pfizer dose and 13.2 percent after the second Pfizer dose, while 22.8 percent of people reported headache after the first dose of the AstraZeneca vaccine.

Nearly 8.4 percent and 14.4 percent of people reported fatigue after the first and second dose of Pfizer vaccine, while 21.1 percent reported fatigue after their first dose of AstraZeneca vaccine. A whopping 57.2 percent and 50.9 percent reported tenderness after the first and second dose of Pfizer vaccine, and 49.3 percent after the first dose of AstraZeneca vaccine, the researchers said.

The study also reports a significant decrease of infection rates from 12 to 21 days after the first dose of the Pfizer (58 percent reduction) and AstraZeneca (39 percent reduction) vaccines compared to a control group. The drop in infection at least 21 days after the first dose for Pfizer is 69 percent and for AstraZeneca 60 percent, the findings showed.

Moreover, Covid survivors were three times more likely to have side effects that affect the whole body after receiving doses of the Pfizer vaccine than those without known infection and almost twice more likely after the first dose of the AstraZeneca vaccine.(IANS/JC)

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)
