While much of the focus has been on antibodies, which help fight off infection, there is also interest in the way our T lymphocytes -- a type of white blood cell -- may build &quot;immunity memory.&quot;</p><p>But little is known yet about how these cells operate against Covid-19.</p><div><strong>CHILDREN AND COVID</strong></div><div class="embed-wrap"><figure data-feedback="fb:likes,fb:comments"><img src="http://sa.kapamilya.com/absnews/abscbnnews/media/2020/afp/09/10/20200426-covid-spain-play-jump-rope-afp.jpg"/><figcaption>A woman jumps rope with a girl in Valencia on April 26, 2020, amid a national lockdown to prevent the spread of the COVID-19 disease. <em>Jose Jordan, AFP</em></figcaption></figure></div><p>As children head back to classrooms, it is still unclear what exact role they play in the spread of coronavirus.</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/news/09/10/20/deped-ready-for-oct-5-school-opening-amid-calls-for-academic-freeze">DepEd ready for Oct. 5 school opening amid calls for academic freeze</a></li></ul><p>We know that severe illness is very rare in young children with COVID-19, with most developing mild symptoms -- or none at all.</p><p>But could they still be vectors of infection?</p><p>&quot;When symptomatic, children shed virus in similar quantities to adults and can infect others in a similar way,&quot; says the European Centre for Disease Prevention and Control.</p><p>&quot;It is unknown how infectious asymptomatic children are.&quot;</p><p>Several studies have suggested children are less likely to transmit the disease, perhaps because with fewer symptoms they would not be coughing or sneezing, which increases the risk of viral spread.</p><p>However, many experts say a distinction should be drawn between young children and adolescents, who appear just as contagious as adults.</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/overseas/09/02/20/us-coronavirus-rates-are-rising-fast-among-children">US coronavirus rates are rising fast among children</a></li></ul><div><br/><strong>VACCINE SAFETY </strong></div><div class="embed-wrap"><figure data-feedback="fb:likes,fb:comments"><img src="http://sa.kapamilya.com/absnews/abscbnnews/media/2020/news/09/10/20200812-makati-community-vaccine-gc-000_9161.jpg"/><figcaption>Health workers administer flu and pneumonia vaccines to 71-year-old Pedro Martinez as part of their community vaccination drive in Barangay Pembo, Makati City on Aug. 12, 2020. <em>George Calvelo, ABS-CBN News</em></figcaption></figure></div><p>Much is riding on the development of an effective, safe vaccine, and this week the WHO listed 35 vaccine candidates going through clinical trials on humans around the world.</p><p>Nine of them are already at, or preparing for, the final stage -- known as Phase 3 -- which requires thousands of volunteers to measure large-scale effectiveness.</p><p>Big-spending superpowers the United States, Russia, and China are accelerating the process in an attempt to be the first to have a vaccine, even before the end of the year.</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/news/09/09/20/russia-eyes-production-of-potential-covid-19-vaccine-in-philippines">Russia eyes production of potential COVID-19 vaccine in Philippines</a></li></ul><p>But experts urge patience, warning that speed should not compromise safety or public confidence.</p><p>As an example of the need for caution, pharmaceutical giant AstraZeneca and the University of Oxford have &quot;paused&quot;
