| A Chinese official admits low vaccine efficacy, new Covid-19 misinformation spreads on Facebook in Arabic, and massive crowds gather in India despite rising cases. Here's what you should know: Headlines Chinese official calls domestic vaccine efficacy into question and touts the benefits of mRNA technology Gao Fu, the director of the Chinese Center for Disease Control and Prevention, acknowledged on Saturday that China's current vaccines don't have high rates of protection. Gao praised the mRNA shots, despite questioning their safety in the past, and added that Chinese officials are considering giving people doses of more than one vaccine. China currently has five vaccines in use, and it has sent hundreds of millions of domestically made doses to other countries around the world. In a follow-up message on Sunday night, Gao qualified that he had been speaking about the efficacy of "vaccines around the world, not particularly for China." New vaccine conspiracy theories are going viral on Facebook in Arabic Researchers at the Institute of Strategic Dialogue found that new vaccine conspiracy theories are gaining significant traction on Facebook. Between January 1 and February 28, they discovered 18 pages and 10 groups with a combined following of more than 2.4 million people sharing pandemic-related misinformation in Arabic. In response, Facebook said that it has three Arabic fact-checking partnerships and is trying to use AI to detect content that violates its rules. Experts point out that Facebook has had a hard time combating misinformation even in English, and it likely has not made the investment necessary to curb the spread of conspiracy theories in other languages. India's case count is the world's highest, but crowds still gathered for a massive Hindu festival As of today, India has surpassed Brazil to become the second-worst-hit country of the pandemic, and case counts show no signs of decreasing anytime soon. Still, this morning India's Ganges River filled with a million people taking a holy bath as part of Kumbh Mela, a months-long festival. It's estimated that less than 4 percent of India's 1.4 billion people have been vaccinated, and some experts have hypothesized that the country's case count could double in two months. Still, authorities have done little to stop events that could worsen the spread, like this festival and political rallies in states with upcoming elections.

For scientists studying air pollution, the last year has been a big natural experiment with largely promising results. It's clear that air quality can improve quickly when drastic measures are taken. For example, a study published last month found that during March and May 2020, air pollution decreased significantly in six major Indian metropolises compared to years prior. Other recent studies have shown similar trends elsewhere. But researchers have also observed these numbers going back up as Covid-19 restrictions loosened. Lasting improvement will likely require more permanent changes.
